Martin Ramos, M.; Noel, M.

2010-01-01

In the European Union, in order to support the Community activities on operational experience, a centralized regional network on nuclear power plants operational experience feedback (European Clearinghouse on Operational Experience Feedback for Nuclear Power Plants) was established in 2008 at the EC JRC-IE, Petten (The Netherlands) on request of nuclear Safety Authorities of several Member States. Its main goal is to improve the communication and information sharing on OEF, to promote regional collaboration on analyses of operational experience and dissemination of the lessons learned. The enlarged EU Clearinghouse was launched in April 2010, and it is currently gathering the Regulatory Authorities of Finland, Hungary, Lithuania, the Netherlands, Romania, Slovenia, Switzerland, Bulgaria, Czec Republic, France, Germany, Slovak Republic, and Spain (these last six countries as observers). The OECD Nuclear Energy Agency, the IAEA, the EC Directorates General of the JRC and ENER are also part of the network. Recently, collaboration between some European Technical Support Organizations (such IRSN and GRS) and the EU Clearinghouse has been initiated. This paper explains in detail the objectives and organization of the EU Clearinghouse, as well as the most relevant activities carried out, like research work in trend analysis of events ocurred in NPP, topical reports on particular events, dissemination of the results, quarterly reports on events reported publicly and operational experience support to the members of the EU Clearinghouse.

The Global Earth Observation System of Systems (GEOSS) is established to support the study of the Earth system in a global community. It provides services for social management, quick response, academic research, and education. The purpose of GEOSS is to achieve comprehensive, coordinated and sustained observations of the Earth system, improve monitoring of the state of the Earth, increase understanding of Earth processes, and enhance prediction of the behavior of the Earth system. In 2009, GEO called for a competition for an official GEOSS clearinghouse to be selected as a source to consolidating catalogs for Earth observations. The Joint Center for Intelligent Spatial Computing at George Mason University worked with USGS to submit a solution based on the open-source platform - GeoNetwork. In the spring of 2010, the solution is selected as the product for GEOSS clearinghouse. The GEOSS Clearinghouse is a common search facility for the Intergovernmental Group on Ea rth Observation (GEO). By providing a list of harvesting functions in Business Logic, GEOSS clearinghouse can collect metadata from distributed catalogs including other GeoNetwork native nodes, webDAV/sitemap/WAF, catalog services for the web (CSW)2.0, GEOSS Component and Service Registry (http://geossregistries.info/), OGC Web Services (WCS, WFS, WMS and WPS), OAI Protocol for Metadata Harvesting 2.0, ArcSDE Server and Local File System. Metadata in GEOSS clearinghouse are managed in a database (MySQL, Postgresql, Oracle, or MckoiDB) and an index of the metadata is maintained through Lucene engine. Thus, EO data, services, and related resources can be discovered and accessed. It supports a variety of geospatial standards including CSW and SRU for search, FGDC and ISO metadata, and WMS related OGC standards for data access and visualization, as linked from the metadata.

Brown-Vialetto-Van Laere syndrome

Full Text Available Abstract The Brown-Vialetto-Van Laere syndrome (BVVL is a rare neurological disorder characterized by progressive pontobulbar palsy associated with sensorineural deafness. Fifty-eight cases have been reported in just over 100 years. The female to male ratio is approximately 3:1. The age of onset of the initial symptom varies from infancy to the third decade. The syndrome most frequently presents with sensorineural deafness, which is usually progressive and severe. Lower cranial nerve involvement and lower and upper motor neuron limb signs are common neurological features. Other features include respiratory compromise (the most frequent non-neurological finding, limb weakness, slurring of speech, facial weakness, and neck and shoulder weakness. Optic atrophy, retinitis pigmentosa, macular hyperpigmentation, autonomic dysfunction, epilepsy may occur. The etiopathogenesis of the condition remains elusive. Approximately 50% of cases are familial, of which autosomal recessive is suggested. The remaining cases are sporadic. The diagnosis is usually based on the clinical presentation. Investigations (neurophysiological studies, magnetic resonance imaging of the brain, muscle biopsy, cerebrospinal fluid examination are done to exclude other causes or to confirm the clinical findings. The differential diagnoses include the Fazio-Londe syndrome, amyotrophic lateral sclerosis, Nathalie syndrome, Boltshauser syndrome and Madras motor neuron disease. Treatment with steroids or intravenous immunoglobulin may result in temporary stabilization of the syndrome. However, the mainstays of management are supportive and symptomatic treatment, in particular assisted ventilation and maintenance of nutrition via gastrostomy. The clinical course of BVVL is variable and includes gradual deterioration (almost half of cases, gradual deterioration with stable periods in between (a third of cases and deterioration with abrupt periods of worsening (just under a fifth of cases

BACT analysis under the Clean Air Act's PCD program

Simms, P.; Walke, J. [National Resources Development Council, Washington, DC (United States)

2006-11-15

Before a company may build a new major industrial source of air pollution, or make modifications to an existing major source in the USA it must apply for and receive a Clean Air Act (CAA) Prevention of Significant Deterioration (PSD) permit. State environmental agencies typically issue such permits, either under state law or by exercising delegated authority to implement the federal PSD program. To fully comply with the CAA, the emissions limits identified as BACT must incorporate consideration of more than just add-on emissions control technology, they must also reflect appropriate considerations of fuel quality (e.g. low-sulfur coal) and process changes (e.g. advanced combustion techniques) as a means of controlling emissions, and must consider the other environmental and public welfare benefits of the identified emissions control options. Several states including New Mexico and Illinois have already determined that innovated technologies, such as Integrated Gasification Combined Cycle (IGCC), must be considered in connection with the BACT analysis for new coal-fired power plants. Even the notion that BACT is categorically limited in scope to the general type of facility proposed is contrary to EPA precedent. For example, the Environmental Appeals Board (EAB) has explained that permitting authorities retain the discretion under the definition of BACT to require dramatically different facility designs (e.g. a natural gas plant instead of a coal-fired power plant). The best advice for any permit applicant is to include in the BACT analysis a careful and honest examination of better performing alternative processes and/or innovative combustion techniques and to aggressively pursue such options wherever feasible. 17 refs.

Résumé Les biofilms bactériens sont des amas structurés de cellules bactériennes enrobés d’une matrice polymérique et attachés à une surface. Le biofilm protège les bactéries et leur permet de survivre dans des conditions environnementales hostiles. Les bactéries du biofilm peuvent résister à la réponse immunitaire de l’hôte et sont beaucoup plus résistantes aux antibiotiques et aux désinfectants que les cellules bactériennes planctoniques. La capacité de former un biofilm est maintenant reconnue comme une caractéristique propre à plusieurs microorganismes. La présence de biofilms lors d’infections demande donc de nouvelles méthodes de prévention, de diagnostic et de traitement. De même, la présence de biofilms sur des surfaces retrouvées à la ferme, à l’abattoir ou à l’usine de transformation affectera l’efficacité du protocole de désinfection. De façon surprenante, la formation de biofilms chez les bactéries pathogènes des animaux et les bactéries zoonotiques est un sujet relativement peu étudié. Ce bref compte rendu a pour objectif de sensibiliser les intervenants en santé animale à l’importance des biofilms. PMID:24688172

European clearinghouse on nuclear power plants operational experience feedback

International Nuclear Information System (INIS)

Ranguelova, Vesselina; Bruynooghe, Christiane; Noel, Marc

2010-01-01

Learning from operational experience and applying this knowledge promptly and intelligently is one of the ways to improve the safety of Nuclear Power Plant (NPP). Recent reviews of the effectiveness of Operational Experience Feedback (OEF) systems have pointed to the need for further improvement, with importance being placed on tailoring the information to the needs of the regulators. In 2007, at the request of a number of nuclear safety regulatory authorities in Europe, the Institute for Energy of the European Commission's Joint Research Centre (EC JRC) initiated a project on Nuclear Power Plant operational experience feedback, which adopts an integrated approach to the research needed to strengthen the European capabilities for assessment of NPP operational events and to promote the development of tools and mechanisms for the improved application of the lessons learned. Consequently, a so-called ''European Clearinghouse'' on NPP OEF was established, which includes scientific officers from the EC JRC, a number of European nuclear safety regulatory authorities and some of their Technical Support Organizations (TSOs). The paper discusses the activities implemented in 2008 within the framework of the European Clearinghouse on NPP OEF (hereinafter called the European NPP Clearinghouse) and provides an overview of the main conclusions drawn from the safety studies performed. Outlook of the activities carried out in 2009 are given. (orig.)

Full Text Available OBJETIVO: Avaliar mudanças, ao longo dos anos, na freqüência de resistência à norfloxacina e ciprofloxacina em bactérias isoladas de uroculturas. MÉTODOS: Resultados de todas as uroculturas com crescimento bacteriano de pelo menos 10(5 unidades formadoras de colônias por mL de urina (UFC/mL, realizadas no Serviço de Nefrologia da Universidade Federal da Bahia durante o período 1983-1994, foram analisadas. As bactérias incluídas na análise foram aquelas mais freqüentemente isolados: Escherichia coli (n=668, Klebsiella spp. (n=286, Staphylococcus spp. (n=186, Proteus spp. (n=135 e Enterobacter spp. (n=129. RESULTADOS: A freqüência de bactérias resistentes à norfloxacina foi de 3,2%, no período 1983-1986; 5,9%, no período 1987-1990; e 9,1%, no período 1991-1994 (p<0,05. Klebsiella spp. e Enterobacter spp. foram as bactérias que apresentaram maiores aumentos na freqüência de resistência à norfloxacina. Para a ciprofloxacina, constatou-se resistência em 7,4% das bactérias isoladas, no período 1985-1989, e 16,5%, no período 1990-1994 (p<0,05. Esse aumento na freqüência de bactérias resistentes à ciprofloxacina foi mais marcante para Enterobacter spp. e Staphylococcus spp. CONCLUSÕES: Os resultados do presente estudo mostram um aumento gradual na freqüência de resistência à norfloxacina e ciprofloxacina entre as bactérias mais comumente isoladas em uroculturas. A influência do uso prévio de quinolonas e de peculiaridades da bactéria infectante, nesses achados, representa importante questão a ser investigada.

First insights from common GRS and IRSN evaluations of operational experiences for the European Clearinghouse

International Nuclear Information System (INIS)

Maqua, M.; Bertrand, R.

2012-01-01

The European Clearinghouse on Operating Experience Feedback (OEF) for NPPs was established in 2008 by several European Nuclear Safety Regulators. The technical work on common operational experience evaluation was launched at the Joint Research Center of the European Union. Main goals of the European Clearinghouse include promotion of collaboration on OEF, dissemination of the lessons learnt from NPP operational experience and promoting advanced event assessment approaches and methods. The extended knowledge of both IRSN and GRS in the evaluation of the national operating experiences in France and Germany, respectively, is used by the European Clearinghouse with the objective of receiving detailed insights on safety related topics. IRSN and GRS develop common reports on safety issues upon request of the Clearinghouse that involve a detailed review of their national event databases, and that are combined afterwards in a European Clearinghouse report including also the review carried out by the JRC on the basis of the Incident Report System (IRS) database and the US NRC Licensee Event Reports (LERs) database. The aim is to perform in-depth analyses (causes, root causes, contributing factors, actual and potential consequences, and lessons learnt) of specific OEF topics. 3 topics have been already analyzed: -) external events (Serious accidents caused by external hazards were not found in the German and French operating experience), -) ageing of components (it can be concluded that ageing management in French and German NPP is basically effective), and -) component supply (the main cause for events related to the supply of components was insufficiency during manufacturing or testing). This paper is followed by the slides of the presentation

The Clearinghouse provides emergency management and response professionals, scientific and engineering communities with prompt information on ground failure, structural damage, and other consequences from significant seismic events such as earthquakes or tsunamis. Clearinghouse activations include participation from Federal, State and local government, law enforcement, fire, EMS, emergency management, public health, environmental protection, the military, public and non-governmental organizations, and private sector. For the August 24, 2014 S. Napa earthquake, over 100 people from 40 different organizations participated during the 3-day Clearinghouse activation. Every organization has its own role and responsibility in disaster response; however all require authoritative data about the disaster for rapid hazard assessment and situational awareness. The Clearinghouse has been proactive in fostering collaboration and sharing Essential Elements of Information across disciplines. The Clearinghouse-led collaborative promotes the use of standard formats and protocols to allow existing technology to transform data into meaningful incident-related content and to enable data to be used by the largest number of participating Clearinghouse partners, thus providing responding personnel with enhanced real-time situational awareness, rapid hazard assessment, and more informed decision-making in support of response and recovery. The Clearinghouse efforts address national priorities outlined in USGS Circular 1242, Plan to Coordinate NEHRP post-earthquake investigations and S. 740-Geospatial Data Act of 2015, Sen. Orrin Hatch (R-UT), to streamline and coordinate geospatial data infrastructure, maximizing geospatial data in support of the Robert T. Stafford Act. Finally, the US Dept. of Homeland Security, Geospatial Management Office, recognized Clearinghouse's data sharing efforts as a Best Practice to be included in the forthcoming 2015 HLS Geospatial Concept of Operations.

Introduction Analyse du profil bactériologique des pieds diabétiques pris en charge à l'hôpital militaire de Rabat et son influence sur l'antibiothérapie de première intention. Méthodes Etude prospective non randomisée étalée sur 18 mois, ayant concerné 105 patients. Après recueil des données et en attente des résultats bactériologiques nos patients ont été divisés en deux groupes: un groupe a été mis sous Amoxicilline + Acide clavulanique + Gentamycine (59 patients) et un groupe sous Ertapénème±Gentamycine (46 patients). Résultats L’étude a regroupé 85 hommes et 20 femmes (sexe ratio = 4.26). L’âge moyen est de 64.4 ans. La gangrène a été observée chez 79% des malades; elle était humide-donc surinfectée en principe- dans 43% des cas. Par ailleurs, 67% des malades ont un chiffre de globules blancs 12000 définissant une infection sévère. L'ostéolyse a été mise en évidence chez 27% de nos patients. Parmi les différentes techniques de prélèvements: 81% ont été profonds dont 21% de biopsie osseuse per opératoire et 14% de prélèvements combinés. 42% de ces prélèvements sont poly microbiens et 21% sont stériles. Les résultats bactériologiques viennent confirmer la prédominance des bactéries aérobies à Gram positif. Le taux de remplacement de l'Ertapénème est de 22% contre un taux de 50% pour l'Amoxiclav. Conclusion L'antibiothérapie ne doit être instaurée qu'en cas d'infection du pied diabétique diagnostiquée sur les critères cliniques établis par les consensus internationaux récents. Le respect des mesures de lutte contre la diffusion de la résistance bactérienne s'avère primordiale. PMID:27386024

2001-10-01

Full Text Available Diazotrophic bacteria isolated from banana plants were characterized by morphological and physiological aspects. Three different groups of these plant-bacteria could be established. Two of them showed similarity to species of the Herbaspirillum genus. The third one was different because used only a few carbon substrates and produced water diffusible compounds that fluoresced under UV light. All three bacterial groups were thin rods with mono or bipolar flagella, presented negative reaction in Gram stain, showed catalase activity, were able to reduce nitrate and grew better in semi-solid JNFb medium at 31ºC. The nitrogenase activity was detected in semi-solid N-free JNFb medium and expressed higher values when pH ranged from 6.5 to 7.0 (groups I and II and 6.0 to 6.5 (group III. The diazotrophs isolated from banana plants were distinct from species of Herbaspirillum previously identified in gramineous plants.Bactérias diazotróficas do tipo Herbaspirillum isoladas de bananeiras foram avaliadas pelas características morfológicas e fisiológicas de crescimento. Três grupos de bactérias foram estabelecidos, sendo dois relacionados às espécies de Herbaspirillum e diferentemente o terceiro grupo apresentou habilidade em crescer com poucos substratos orgânicos e produziu substância fluorescente em meio B de King. As bactérias dos três grupos eram bastonetes com flagelos mono ou bipolares, apresentaram reação negativa na coloração de Gram, expressaram atividade de catalase e oxidade, foram capazes de reduzir o nitrato e cresceram melhor em meio JNFb semi-sólido incubado a 31ºC. A atividade da nitrogenase, medida através da atividade de redução de acetileno, foi máxima em meio JNFb semi-sólido, após o ajuste de pH na faixa de 6,0 a 7,0 (grupos I e II e 5,5 a 6,5 (grupo III. As bactérias diazotróficas associadas às bananeiras são diferentes das espécies de Herbaspirillum anteriormente identificadas em gramíneas.

Smart Grid Information Clearinghouse (SGIC)

2014-08-31

Since the Energy Independence and Security Act of 2007 was enacted, there has been a large number of websites that discusses smart grid and relevant information, including those from government, academia, industry, private sector and regulatory. These websites collect information independently. Therefore, smart grid information was quite scattered and dispersed. The objective of this work was to develop, populate, manage and maintain the public Smart Grid Information Clearinghouse (SGIC) web portal. The information in the SGIC website is comprehensive that includes smart grid information, research & development, demonstration projects, technical standards, costs & benefit analyses, business cases, legislation, policy & regulation, and other information on lesson learned and best practices. The content in the SGIC website is logically grouped to allow easily browse, search and sort. In addition to providing the browse and search feature, the SGIC web portal also allow users to share their smart grid information with others though our online content submission platform. The Clearinghouse web portal, therefore, serves as the first stop shop for smart grid information that collects smart grid information in a non-bias, non-promotional manner and can provide a missing link from information sources to end users and better serve users’ needs. The web portal is available at www.sgiclearinghouse.org. This report summarizes the work performed during the course of the project (September 2009 – August 2014). Section 2.0 lists SGIC Advisory Committee and User Group members. Section 3.0 discusses SGIC information architecture and web-based database application functionalities. Section 4.0 summarizes SGIC features and functionalities, including its search, browse and sort capabilities, web portal social networking, online content submission platform and security measures implemented. Section 5.0 discusses SGIC web portal contents, including smart grid 101, smart grid projects

Bactérias e fungos benéficos na endosfera das plantas

Julierme Zimmer Barbosa

2014-10-01

Full Text Available No solo, a região da rizosfera em comparação com a massa de solo apresenta marcado contraste biológico, sendo um nicho de grande densidade e diversidade de microorganismos.  Alguns fungos e bactérias benéficos ao desenvolvimento vegetal têm capacidade de colonizar o interior de plantas a partir do solo, conhecidos como organismos endofíticos. Possivelmente sejam as bactérias nodulíferas, com sua reconhecida capacidade de fixar N em leguminosas as mais conhecidas. Bactérias não nodulíferas tem a capacidade de colonizar o interior das raízes das plantas através de regiões de crescimento, em seguida, podem ser carregadas via xilema rumo à parte aérea. Podem ser encontrados em todos os órgãos vegetais, todavia, poucos estudos têm analisado as populações que transitam no continuum solo-planta até atingir caules, folhas, flores, frutos e sementes. O ultimo grupo de organismos endofíticos apresentado é o grupo dos fungos micorrízicos, esses se caracterizam como um sistema de exploração do solo paralelo ao sistema radicular que, com diâmetro extremamente reduzido conseguem minar um grande volume de solo com pequena alocação de C, o que é extremamente benéfico na aquisição de nutrientes, também podem ser benéficos em condições abióticas adversas. Em adição, alguns fungos endofíticos benéficos também podem colonizar órgãos aéreos das plantas. As interações microbiológicas que ocorrem na endosfera são altamente complexas, simultâneas e dependentes de uma série de fatores, assim seu entendimento é de fundamental importância à aplicação prática dos conhecimentos acerca de microorganismos endofíticos em agrossistemas.

As computing has changed, so has the role of both the compiler and the compiler writer. The proliferation of processors, environments, and constraints demands an equally large number of compilers. To adapt, compiler writers retarget code generators, add optimizations, and work on issues such as code space or power consumption. Engineering a Compiler re-balances the curriculum for an introductory course in compiler construction to reflect the issues that arise in today's practice. Authors Keith Cooper and Linda Torczon convey both the art and the science of compiler construction and show best practice algorithms for the major problems inside a compiler. ·Focuses on the back end of the compiler-reflecting the focus of research and development over the last decade ·Applies the well-developed theory behind scanning and parsing to introduce concepts that play a critical role in optimization and code generation. ·Introduces the student to optimization through data-flow analysis, SSA form, and a selection of sc...

Ocorrências de bactérias solubilizadoras de fosfato de cálcio nas raízes de plantas na Amazônia brasileira

2001-09-01

Full Text Available O uso de bactérias solubilizadoras de fosfato pode ser uma alternativa de baixo custo em sistemas agroflorestais na Amazônia, onde os preços e o transporte, aliados à baixa capacidade de aquisição dos produtores, dificultam o uso de adubos solúveis. Em solos sem histórico de cultivo, os fosfatos estão ligados principalmente ao Al, enquanto nos previamente cultivados e corrigidos com calagem, esses fosfatos podem estar ligados ao Ca, limitando seus usos pelas plantas. Existem poucas informações sobre bactérias solubilizadoras de fosfato (BSF na Amazônia, sendo necessário intensificar os estudos nesse sentido. O primeiro passo dessas pesquisas é um estudo sobre a ecologia dessas bactérias, identificando o local e a freqüência de ocorrência. Para isso, foram coletadas amostras de raízes de plantas nos estados do Acre, Amazonas e Rondônia, as quais foram colocadas em placas de Petri com um meio específico capaz de identificar suas presenças. Foram utilizados 28 espécies de plantas de diversas famílias e dois tipos de vegetação múltipla (pastagem e capoeira. Os índices de presença dessas bactérias foram muito baixos (0-10%, evidenciando que, nessas condições, essas bactérias não contribuem efetivamente para melhorar a nutrição das plantas com fósforo.

2012-11-01

Brown-Vialetto-Van Laere syndrome (BVVLS [MIM 211530]) is a rare neurological disorder characterized by infancy onset sensorineural deafness and ponto-bulbar palsy. Mutations in SLC52A3 (formerly C20orf54), coding for riboflavin transporter 2 (hRFT2), have been identified as the molecular genetic correlate in several individuals with BVVLS. Exome sequencing of just one single case revealed that compound heterozygosity for two pathogenic mutations in the SLC52A2 gene coding for riboflavin transporter 3 (hRFT3), another member of the riboflavin transporter family, is also associated with BVVLS. Overexpression studies confirmed that the gene products of both mutant alleles have reduced riboflavin transport activities. While mutations in SLC52A3 cause decreased plasma riboflavin levels, concordant with a role of SLC52A3 in riboflavin uptake from food, the SLC52A2-mutant individual had normal plasma riboflavin concentrations, a finding in line with a postulated function of SLC52A2 in riboflavin uptake from blood into target cells. Our results contribute to the understanding of human riboflavin metabolism and underscore its role in the pathogenesis of BVVLS, thereby providing a rational basis for a high-dose riboflavin treatment.

Rosinski, A.; Morentz, J.; Beilin, P.

2017-12-01

The principal function of the California Earthquake Clearinghouse is to provide State and Federal disaster response managers, and the scientific and engineering communities, with prompt information on ground failure, structural damage, and other consequences from significant seismic events such as earthquakes and tsunamis. The overarching problem highlighted in discussions with Clearinghouse partners is the confusion and frustration of many of the Operational Area representatives, and some regional utilities throughout the state on what software applications they should be using and maintaining to meet State, Federal, and Local, requirements, and for what purposes, and how to deal with the limitations of these applications. This problem is getting in the way of making meaningful progress on developing multi-application interoperability and the necessary supporting cross-sector information-sharing procedures and dialogue on essential common operational information that entities need to share for different all hazards missions and related operational activities associated with continuity, security, and resilience. The XchangeCore based system the Clearinghouse is evolving helps deal with this problem, and does not compound it by introducing yet another end-user application; there is no end-user interface with which one views XchangeCore, all viewing of data provided through XchangeCore occurs in and on existing, third-party operational applications. The Clearinghouse efforts with XchangeCore are compatible with FEMA, which is currently using XchangeCore-provided data for regional and National Business Emergency Operations Center (source of business information sharing during emergencies) response. Also important, and should be emphasized, is that information-sharing is not just for response, but for preparedness, risk assessment/mitigation decision-making, and everyday operational needs for situational awareness. In other words, the benefits of the Clearinghouse

Ana Flávia Mairinck Meirelles

Full Text Available RESUMO A alface é uma das hortaliças folhosas mais consumidas no Brasil, gerando grande demanda por seu cultivo. É cultura exigente em nutrientes e requer solo rico em matéria orgânica para obtenção de produtividade elevada, com necessidade de aplicação de grandes doses de compostos orgânicos, onerando os custos da produção. Ácidos húmicos (AH e bactérias diazotróficas (B apresentam hormônios vegetais, como auxinas, que promovem alongamento celular, aumento das raízes e da absorção de nutrientes, levando ao crescimento e desenvolvimento das plantas. Por essas características, podem ser utilizados como bioestimulantes na promoção da produtividade da alface. O objetivo deste trabalho foi avaliar a produtividade da alface em resposta à aplicação de ácidos húmicos e bactérias diazotróficas, em condições de campo. Os ácidos húmicos foram isolados de esterco bovino e as bactérias usadas foram provenientes da coleção de bactérias do Setor de Floricultura da Universidade Federal de Viçosa - Campus Florestal, extraídas de orquídeas Cymbidium sp.. O experimento foi realizado em condições de campo, com o cv.

O delineamento adotado foi em blocos casualizados, com cinco repetições. A aplicação dos bioestimulantes foi realizada logo após o transplantio. Foram avaliados atributos fitotécnicos da parte aérea das plantas. Concluiu-se que os tratamentos utilizados, principalmente a combinação AH+B, aumentaram a produtividade da alface.

EVALUATION DE L’IMPACT ENVIRONNEMENTAL : Evaluation des potentialités de transfert de l’ADN des plantes transgéniques vers les bactéries du sol

Directory of Open Access Journals (Sweden)

Simonet Pascal

2000-07-01

Full Text Available Les bactéries se caractérisent par leurs stratégies évolutives multiples incluant mutations ponctuelles, remaniements endogènes par déplacements de séquences d’insertion ou de transposons, délétions ou amplifications de larges régions d’ADN et acquisition de nouveaux gènes par transfert horizontal d’informations génétiques. Les récentes et toutes premières analyses conduites sur les données des quelques génomes bactériens totalement séquencés indiquent le rôle tout à fait fondamental qu’ont pu jouer les transferts latéraux de gènes dans l’évolution bactérienne [1-3]. Nombre de travaux sont aujourd’hui conduits afin d’élucider le rôle des trois mécanismes de transfert (conjugaison, transformation et transduction dans l’évolution et l’adaptation des bactéries aux conditions changeantes de leur environnement. En particulier, l’accroissement inquiétant de la proportion de germes résistants aux antibiotiques serait le fait de la dispersion de plasmides porteurs des gènes de résistance parmi la microflore pathogène ? Dans ces cisconstances, la question de savoir si les plantes transgéniques, très souvent pourvues de tels gènes, pourraient constituer un facteur aggravant la dissémination d’éléments menaçant potentiellement la santé humaine est donc totalement justifiée. Tout au long de l’évolution, la nature a cependant établi un certain nombre de filtres moléculaires afin de limiter les flux de gènes, notamment entre organismes phylétiquement très éloignés. La caractéristique des plantes transgéniques tient à ce que certains des gènes des transgènes, et en particulier ceux conférant la résistance aux antibiotiques, ont une origine procaryotique susceptible de leur permettre de contourner les barrières moléculaires. Cependant, d’autres facteurs environnementaux, biotiques et abiotiques vont intervenir pour favoriser ou au contraire limiter les échanges de g

Michael D. Sharp

1993-01-01

Full Text Available Class-specific optimizations are compiler optimizations specified by the class implementor to the compiler. They allow the compiler to take advantage of the semantics of the particular class so as to produce better code. Optimizations of interest include the strength reduction of class:: array address calculations, elimination of large temporaries, and the placement of asynchronous send/recv calls so as to achieve computation/communication overlap. We will outline our progress towards the implementation of a C++ compiler capable of incorporating class-specific optimizations.

Full Text Available Araucaria angustifolia is an environmentally threatened tree and the whole biota of the Araucaria Forest should be investigated with the aim of its preservation. Diazotrophic bacteria are extremely important for the maintenance of ecosystems, but they have never been studied in Araucaria Forests. In this study, diazotrophic bacteria were isolated from Araucaria roots and soil, when grown in semi-specific, semi-solid media. The diazotrophic character of some recovered isolates could be confirmed using the acetylene reduction assay. According to their 16S rRNA sequences, most of these isolates belong to the genus Burkholderia.Araucaria angustifolia é uma espécie arbórea ameaçada de extinção e toda a comunidade viva das Florestas de Araucária deve ser estudada com a finalidade de sua preservação.

1994-05-01

The US Department of Energy's (DOE's) Pollution Prevention Information Clearinghouse (EPIC) is a computer system intended for the exchange of pollution prevention information DOE-wide. EPIC is being developed as a distributed system that will allow access to other databases and applications. The first prototype of EPIC (Prototype I) was put on-line in January 1994. Prototype I contains information on EM-funded pollution prevention projects; relevant laws, regulations, guidance, and policy; facility and DOE contacts; and meetings and conferences. Prototype I also gives users access to the INEL Hazardous Solvent Substitution Data System (HSSDS) and to information contained on the US Environmental Protection Agency's (EPNS) Pollution Prevention Infbrmation Exchange System (PIES) as a test of the distributed system concept. An initial user group of about 35 is testing and providing feedback on Prototype I. Prototype II, with a Graphical User Interface (GUI), is planned for the end of CY94. This paper describes the current state of EPIC in terms of architecture, user interface, and information content. Plans for Prototype II and the final system are then discussed. The EPIC development effort is being coordinated with EPA and US Department of Defense (DoD) efforts to develop or upgrade their pollution prevention information exchange systems

If file A depends on file B, (A uses a module defined by B), you must finish compiling B before you can begin compiling A. Some Fortran compilers (Intel ifort, GNU gfortran and IBM xlf, at least) offer an option to ‘‘verify syntax’’, with the side effect of also producing any associated Fortran module files. As it happens, this option usually runs much faster than the object code generation and optimization phases. For some projects on some machines, it can be advantageous to compile in two passes: The first pass generates the module files, quickly; the second pass produces the object files, in parallel. We achieve a 3.8× speedup in the case study below.

Feliciano, M.; Anderson, H. D.; Bond, J. W., III

1976-01-01

NASA/Langley is engaged in a program to develop an adaptable guidance and control software concept for spacecraft such as shuttle-launched payloads. It is envisioned that this flight software be written in a higher-order language, such as HAL/S, to facilitate changes or additions. To make this adaptable software transferable to various onboard computers, a compiler writing system capability is necessary. A joint program with the Air Force Space and Missile Systems Organization was initiated to determine if the Compiler Writing System (CWS) owned by the Air Force could be utilized for this purpose. The present study explores the feasibility of including the HAL/S language constructs in CWS and the effort required to implement these constructs. This will determine the compilability of HAL/S using CWS and permit NASA/Langley to identify the HAL/S constructs desired for their applications. The study consisted of comparing the implementation of the Space Programming Language using CWS with the requirements for the implementation of HAL/S. It is the conclusion of the study that CWS already contains many of the language features of HAL/S and that it can be expanded for compiling part or all of HAL/S. It is assumed that persons reading and evaluating this report have a basic familiarity with (1) the principles of compiler construction and operation, and (2) the logical structure and applications characteristics of HAL/S and SPL.

Rôle des bactéries sulfurogènes dans la corrosion du fer Involvment of Sulfidogenic Bacteria in Iron Corrosion

Directory of Open Access Journals (Sweden)

Marchal R.

2006-12-01

Full Text Available Cet article fait le point sur les connaissances concernant l'implication des bactéries sulfurogènes dans la corrosion des aciers au carbone. Après la description de quelques cas récents tirés de l'industrie pétrolière, la physiologie des bactéries sulfurogènes qui jouent le rôle principal dans le mécanisme de la corrosion anaérobie d'origine bactérienne est examinée. La participation des bactéries productrices d'H2S à la constitution de biofilms est une condition importante à la manifestation des phénomènes de corrosion. Les différentes hypothèses de mécanismes décrites par la littérature sont passées en revue. Indépendamment du rôle physicochirnique joué par les sulfures de fer, non couvrants, bons conducteurs électriques, il en ressort que l'acidification résultant du métabolisme cellulaire est un facteur crucial, non seulement en termes d'électrochimie, mais également en termes de croissance microbienne. L'acidification métabolique explique vraisemblablement la fourniture des ions ferreux pour le micro-organisme dans un environnement chargé d'ions sulfures et finalement la persistance de son activité physiologique dans un micro environnement riche en H2S. The involvement of sulfidogenic bacteria in the corrosion of carbon steel is reviewed. After a brief description of some recent cases drawn from the petroleum industry, the physiology of the sulfidogenic bacteria which plays the most important role in the mechanism of anaerobic bacterial corrosion is examined. The involvement of H2S-producing bacteria to the biofilm formation is a prerequisite for biocorrosion. The hypothetical mechanisms described in the literature are reviewed. Regardless of the physicochemical role played by iron sulfides, which have been shown to be non-covering and to have good properties of electric conductivity, the acidification arising from cellular metabolism has been found to be an important parameter, not only in terms of

Compiler issues associated with safety-related software

International Nuclear Information System (INIS)

Feinauer, L.R.

1991-01-01

A critical issue in the quality assurance of safety-related software is the ability of the software to produce identical results, independent of the host machine, operating system, or compiler version under which the software is installed. A study is performed using the VIPRE-0l, FREY-01, and RETRAN-02 safety-related codes. Results from an IBM 3083 computer are compared with results from a CYBER 860 computer. All three of the computer programs examined are written in FORTRAN; the VIPRE code uses the FORTRAN 66 compiler, whereas the FREY and RETRAN codes use the FORTRAN 77 compiler. Various compiler options are studied to determine their effect on the output between machines. Since the Control Data Corporation and IBM machines inherently represent numerical data differently, methods of producing equivalent accuracy of data representation were an important focus of the study. This paper identifies particular problems in the automatic double-precision option (AUTODBL) of the IBM FORTRAN 1.4.x series of compilers. The IBM FORTRAN version 2 compilers provide much more stable, reliable compilation for engineering software. Careful selection of compilers and compiler options can help guarantee identical results between different machines. To ensure reproducibility of results, the same compiler and compiler options should be used to install the program as were used in the development and testing of the program

Introduction L'eau est utilisée d'une façon primordiale dans tout le processus de la fabrication des produits alimentaires. Les industries agroalimentaires du Nord du Maroc utilisent différentes sources d'eaux mais l'eau de réseau public et l'eau de puits sont les principales sources d'eau utilisée. Cette eau peut s'avérer la source principale des éventuelles contaminations et altérations des aliments. Notre but est d'évaluer la qualité bactériologique de l'eau utilisée par les industries agroalimentaires dans la région du Nord du Maroc, d'identifier les différents germes responsables de la pollution de ces eaux et de définir les principales causes de cette pollution. Méthodes Des échantillons d'eau prélevés aux robinets ou des puits ont été analysés pour la recherche des germes indicateurs de la pollution (coliformes totaux (CT), coliformes fécaux (CF), entérocoques intestinaux (E), microorganismes revivifiables (MOR), anaérobies sulfitoréducteurs) et les germes pathogènes (Salmonelles, Staphylocoques, Pseudomonas aeruginosa). Le dénombrement des bactéries a été fait par la technique de filtration et par incorporation en milieu solide en surfusion. Résultats Les résultats ont montré que les eaux du réseau public ont été de qualité bactériologique satisfaisante tandis que 40% des eaux des puits ont été non conformes aux normes à cause de la présence des indicateurs de pollution CT, CF, E et MOR. En revanche, les germes pathogènes, en particulier les Salmonelles, ont été absents dans les eaux de tous les puits analysés. Conclusion La pollution de ces puits a été généralement liée au non-respect des conditions de puisage hygiéniques. La qualité bactériologique des eaux de ces puits peut être améliorée par une protection adéquate. PMID:28450992

C to VHDL compiler

Science.gov (United States)

Berdychowski, Piotr P.; Zabolotny, Wojciech M.

2010-09-01

The main goal of C to VHDL compiler project is to make FPGA platform more accessible for scientists and software developers. FPGA platform offers unique ability to configure the hardware to implement virtually any dedicated architecture, and modern devices provide sufficient number of hardware resources to implement parallel execution platforms with complex processing units. All this makes the FPGA platform very attractive for those looking for efficient heterogeneous, computing environment. Current industry standard in development of digital systems on FPGA platform is based on HDLs. Although very effective and expressive in hands of hardware development specialists, these languages require specific knowledge and experience, unreachable for most scientists and software programmers. C to VHDL compiler project attempts to remedy that by creating an application, that derives initial VHDL description of a digital system (for further compilation and synthesis), from purely algorithmic description in C programming language. This idea itself is not new, and the C to VHDL compiler combines the best approaches from existing solutions developed over many previous years, with the introduction of some new unique improvements.

Algorithmic synthesis using Python compiler

Science.gov (United States)

Cieszewski, Radoslaw; Romaniuk, Ryszard; Pozniak, Krzysztof; Linczuk, Maciej

2015-09-01

This paper presents a python to VHDL compiler. The compiler interprets an algorithmic description of a desired behavior written in Python and translate it to VHDL. FPGA combines many benefits of both software and ASIC implementations. Like software, the programmed circuit is flexible, and can be reconfigured over the lifetime of the system. FPGAs have the potential to achieve far greater performance than software as a result of bypassing the fetch-decode-execute operations of traditional processors, and possibly exploiting a greater level of parallelism. This can be achieved by using many computational resources at the same time. Creating parallel programs implemented in FPGAs in pure HDL is difficult and time consuming. Using higher level of abstraction and High-Level Synthesis compiler implementation time can be reduced. The compiler has been implemented using the Python language. This article describes design, implementation and results of created tools.

The development of oncology treatment guidelines: an analysis of the National Guidelines Clearinghouse.

Palta, Manisha; Lee, W Robert

2011-01-01

In the last 2 decades, guidelines have been developed to improve quality of patient care. A recent editorial of guideline development procedures suggested the process has significant limitations that affect their scientific validity.(1) This prompted us to review oncology treatment guidelines to determine if such limitations are widespread. We performed a review of oncology treatment guidelines registered at the National Guidelines Clearinghouse (www.guideline.gov). Each guideline was independently reviewed by 2 authors and the following criteria were assessed: coordinating organization, guideline panel composition, reporting conflict of interest, peer review, dissent, expiration date, PubMed citation, and evidence-based scoring and grading of recommendations. Disagreements were resolved by consensus in subsequent discussions. Sixty-four guidelines were reviewed (39 [61%] were developed by a medical specialty society and 25 [39%] were developed by government agencies). Fifty (78%) guideline panels were multidisciplinary and 44 (69%) included individuals with epidemiologic and health services research expertise. Potential conflicts of interest were disclosed in 43 (67%) guidelines. Sixty (94%) guidelines underwent peer review, with external review in 31 (48%). Seventeen (27%) guidelines are indexed by PubMed. Fifty-one (80%) guidelines included evidence-based methodologies and 46 (72%) used evidence-based scoring of recommendations. Significant differences were observed according to coordinating organization (eg, disclosure of conflict of interest in 46% of guidelines developed by medical specialty societies versus 100% authored by government agencies [P <.0001]). The majority of oncology-related treatment guidelines registered at the National Guidelines Clearinghouse satisfy most of the criteria for sound guideline development. Significant differences in these criteria were observed according to the coordinating organization that developed the guideline. Copyright

Full Text Available Os ácidos húmicos podem atuar no aumento da população de bactérias diazotróficas introduzidas no interior da planta e, consequentemente, no incremento dos efeitos benéficos sobre a planta hospedeira. Com este trabalho, objetivou-se avaliar o efeito dos ácidos húmicos na inoculação de bactérias diazotróficas endofíticas, em sementes de milho. Foi utilizada a estirpe Herbaspirillum seropedicae Z67 BR 11175. A inoculação das sementes com as bactérias e a adição de ácidos húmicos foram realizadas pelo recobrimento das sementes de milho UENF 506-8, com a mistura de calcário, meio de cultura semisólido, água e cimentante. As sementes recobertas foram semeadas em vasos Leonard. Aos 40 dias após a semeadura, as plântulas foram coletadas, e foi realizada a contagem de bactérias nas raízes pela técnica do Número Mais Provável. Os resultados deste trabalho mostram que os ácidos húmicos não interferem negativamente no crescimento das bactérias e estimulam a colonização da microbiota nativa. No entanto, nas condições avaliadas, a aplicação conjunta de bactérias + ácidos húmicos não estimulou o crescimento da população de bactérias inoculadas nas plântulas de milho.The objective of this research was to evaluate the effect of the humic acids in the inoculation of endophytic diazotrophic bacteria in corn seeds.

ALGOL compiler. Syntax and semantic analysis

International Nuclear Information System (INIS)

Tarbouriech, Robert

1971-01-01

In this research thesis, the author reports the development of an ALGOL compiler which performs the main following tasks: systematic scan of the origin-programme to recognise the different components (identifiers, reserved words, constants, separators), analysis of the origin-programme structure to build up its statements and arithmetic expressions, processing of symbolic names (identifiers) to associate them with values they represent, and memory allocation for data and programme. Several issues are thus addressed: characteristics of the machine for which the compiler is developed, exact definition of the language (grammar, identifier and constant formation), syntax processing programme to provide the compiler with necessary elements (language vocabulary, precedence matrix), description of the first two phases of compilation: lexicographic analysis, and syntax analysis. The last phase (machine-code generation) is not addressed

INIS strategic planning and INIS Clearinghouse document delivery: from four weeks to four minutes

I joined INIS in May 1994 as a consultant to create a Strategic Plan for 1995–2000. I had left a US Department of Justice contractor, Aspen Corporation, which operated the National Criminal Justice Reference Service (NCJRS), as chief of two libraries and manager of a clearinghouse for the world’s criminal justice literature. NCJRS collected this literature, created a bibliographic on-line database and converted non-copyrighted literature to microfiche. The government contract had to be renewed every five years and the Aspen proposal was basically a five year strategic plan, to which I contributed. Thus, when I came to INIS, I had an understanding of the process. The next six months were devoted to preparing STRATEGIC GUIDELINES FOR INIS DEVELOPMENTS 1995–2000 with the caveat: Notice: The guidelines proposed in this report are those of the Information Consultant. They represent a wide range of options that are being presented for further refinement by Peer Reviewers, INIS Consultants and finally the Advisory Committee for INIS. Forwarding of these guidelines does not represent concurrence or nonconcurrence by the INIS Secretariat. 30 September 1994. Member States are now collecting and submitting most of their NCL in electronic format. It is sent to INIS for quality control and consolidation. Consequently, INIS staff has been gradually reduced. The amount of NCL disseminated has remained constant, and an ongoing process to digitize the entire INIS collection on microfiche will be completed in 2016, a process I started in 1999. Before leaving INIS in 1999, I realized that the future would provide a reduced requirement for INIS imaging and recommended the Clearinghouse become a resource for all of the IAEA. Today it serves that purpose

L’asplénie, qu’elle soit fonctionnelle ou anatomique, s’associe à un accroissement du risque d’infection potentiellement fatale ou constituant un danger de septicémie postsplénectomie (SPS). En raison du risque accru de bactériémie par des bactéries encapsulées chez les enfants aspléniques, la vaccination visant à prévenir une infection au Streptococcus pneumoniae, à l’Haemophilus influenzae de type b (Hib) et au Neiserria meningitidis est recommandée. Malgré la prévalence croissante de S pneumoniae pénicillinorésistant, on recommande aussi l’usage de pénicilline prophylactique chez les enfants aspléniques de moins de cinq ans, et pendant au moins un an après une splénectomie. La poursuite de la prophylaxie antibiotique après cette période dépend de la situation clinique de chaque enfant et de la prévalence de S pneumoniae pénicillinorésistant au sein de la collectivité. Lorsque des enfants aspléniques font de la fièvre ou présentent des symptômes non spécifiques, ils devraient faire l’objet d’une évaluation immédiate. Si on présume la présence de septicémie bactérienne, il faut procéder à une analyse du sang et des autres liquides organiques pertinents et entreprendre sur-le-champ une antibiothérapie à large spectre par voie parentérale, laquelle doit agir également contre les souches de S pneumoniae présentes dans la collectivité. Chez les enfants aspléniques souffrant d’une septicémie foudroyante à S pneumoniae, le taux de mortalité est élevé, malgré l’utilisation rapide d’une antibiothérapie convenable, d’où l’importance des mesures préventives.

Python based high-level synthesis compiler

Science.gov (United States)

Cieszewski, Radosław; Pozniak, Krzysztof; Romaniuk, Ryszard

2014-11-01

This paper presents a python based High-Level synthesis (HLS) compiler. The compiler interprets an algorithmic description of a desired behavior written in Python and map it to VHDL. FPGA combines many benefits of both software and ASIC implementations. Like software, the mapped circuit is flexible, and can be reconfigured over the lifetime of the system. FPGAs therefore have the potential to achieve far greater performance than software as a result of bypassing the fetch-decode-execute operations of traditional processors, and possibly exploiting a greater level of parallelism. Creating parallel programs implemented in FPGAs is not trivial. This article describes design, implementation and first results of created Python based compiler.

Automatic Parallelization An Overview of Fundamental Compiler Techniques

CERN Document Server

Midkiff, Samuel P

2012-01-01

Compiling for parallelism is a longstanding topic of compiler research. This book describes the fundamental principles of compiling "regular" numerical programs for parallelism. We begin with an explanation of analyses that allow a compiler to understand the interaction of data reads and writes in different statements and loop iterations during program execution. These analyses include dependence analysis, use-def analysis and pointer analysis. Next, we describe how the results of these analyses are used to enable transformations that make loops more amenable to parallelization, and

A software methodology for compiling quantum programs

Science.gov (United States)

Häner, Thomas; Steiger, Damian S.; Svore, Krysta; Troyer, Matthias

2018-04-01

Quantum computers promise to transform our notions of computation by offering a completely new paradigm. To achieve scalable quantum computation, optimizing compilers and a corresponding software design flow will be essential. We present a software architecture for compiling quantum programs from a high-level language program to hardware-specific instructions. We describe the necessary layers of abstraction and their differences and similarities to classical layers of a computer-aided design flow. For each layer of the stack, we discuss the underlying methods for compilation and optimization. Our software methodology facilitates more rapid innovation among quantum algorithm designers, quantum hardware engineers, and experimentalists. It enables scalable compilation of complex quantum algorithms and can be targeted to any specific quantum hardware implementation.

The Brown-Vialetto-Van Laere and Fazio Londe syndrome revisited: natural history, genetics, treatment and future perspectives

Directory of Open Access Journals (Sweden)

Bosch Annet M

2012-10-01

Full Text Available Abstract The Brown-Vialetto-Van Laere syndrome is a rare neurological disorder which may present at all ages with sensorineural deafness, bulbar palsy and respiratory compromise. Fazio-Londe syndrome is considered to be the same disease entity. Recently it was demonstrated that in some patients the disease is caused by mutations in the SLC52A3 gene which encodes the intestinal (hRFT2 riboflavin transporter. In these patients riboflavin deficiency is the cause of the BVVL/FL syndrome and supplementation of riboflavin proved a life saving treatment. Mutations in the SLC52A2 gene and the SLC52A1 (GPR172B gene, coding for human riboflavin transporters hRFT3 and hRFT1 have been associated with the BVVL syndrome as well. We performed a review of the literature, with emphasis on the natural history and the effects of treatment in these patients. A total of 35 publications were traced reporting on the clinical presentation of 74 patients who presented before age 18. The most prevalent symptoms were bulbar palsy, hearing loss, facial weakness and respiratory compromise. Death was reported in 28 of the 61 untreated patients, with a very low survival in patients presenting before age 4. All 13 patients who were treated with riboflavin survived, with a strong clinical improvement after days to months of treatment in eight patients. Three patients demonstrated a stable clinical course and treatment was stopped early in two patients. Abnormalities in plasma flavin levels and/or plasma acylcarnitine profiles were observed in some but not in all patients, and also patients with normal plasma flavin levels and acylcarnitine profiles demonstrated a striking clinical improvement on riboflavin supplementation. It is now clear that proper diagnosis requires mutation analysis of all three transporter genes and treatment should be started immediately without first awaiting results of molecular analysis. Clinical improvement may be rapid or gradual over a period of

There were two objectives: first, to review the existing data on energy costs of specified activities in the light of the recommendations made by the Joint Food and Agriculture Organization/World Health Organization/United Nations University (FAO/WHO/UNU) Expert Consultation of 1985. Second, to compile existing data on the energy costs of physical activities for an updated annexure of the current Expert Consultation on Energy and Protein Requirements. Electronic and manual search of the literature (predominantly English) to obtain published data on the energy costs of physical activities. The majority of the data prior to 1955 were obtained using an earlier compilation of Passmore and Durnin. Energy costs were expressed as physical activity ratio (PAR); the energy cost of the activity divided by either the measured or predicted basal metabolic rate (BMR). The compilation provides PARs for an expanded range of activities that include general personal activities, transport, domestic chores, occupational activities, sports and other recreational activities for men and women, separately, where available. The present compilation is largely in agreement with the 1985 compilation, for activities that are common to both compilations. The present compilation has been based on the need to provide data on adults for a wide spectrum of human activity. There are, however, lacunae in the available data for many activities, between genders, across age groups and in various physiological states.

Research and development was carried out concerning the automatic parallelized compiler technology which improves on the practical performance, cost/performance ratio, and ease of operation of the multiprocessor system now used for constructing supercomputers and expected to provide a fundamental architecture for microprocessors for the 21st century. Efforts were made to develop an automatic multigrain parallelization technology for extracting multigrain as parallelized from a program and for making full use of the same and a parallelizing tuning technology for accelerating parallelization by feeding back to the compiler the dynamic information and user knowledge to be acquired during execution. Moreover, a benchmark program was selected and studies were made to set execution rules and evaluation indexes for the establishment of technologies for subjectively evaluating the performance of parallelizing compilers for the existing commercial parallel processing computers, which was achieved through the implementation and evaluation of the 'Advanced parallelizing compiler technology research and development project.'

Compiling quantum circuits to realistic hardware architectures using temporal planners

Science.gov (United States)

Venturelli, Davide; Do, Minh; Rieffel, Eleanor; Frank, Jeremy

2018-04-01

To run quantum algorithms on emerging gate-model quantum hardware, quantum circuits must be compiled to take into account constraints on the hardware. For near-term hardware, with only limited means to mitigate decoherence, it is critical to minimize the duration of the circuit. We investigate the application of temporal planners to the problem of compiling quantum circuits to newly emerging quantum hardware. While our approach is general, we focus on compiling to superconducting hardware architectures with nearest neighbor constraints. Our initial experiments focus on compiling Quantum Alternating Operator Ansatz (QAOA) circuits whose high number of commuting gates allow great flexibility in the order in which the gates can be applied. That freedom makes it more challenging to find optimal compilations but also means there is a greater potential win from more optimized compilation than for less flexible circuits. We map this quantum circuit compilation problem to a temporal planning problem, and generated a test suite of compilation problems for QAOA circuits of various sizes to a realistic hardware architecture. We report compilation results from several state-of-the-art temporal planners on this test set. This early empirical evaluation demonstrates that temporal planning is a viable approach to quantum circuit compilation.

Mining User spatiotemporal Behavior in Geospatial Cyberinfrastructure --using GEOSS Clearinghouse as an example

XIA, J.; Yang, C.; Liu, K.; Huang, Q.; Li, Z.

2013-12-01

Big Data becomes increasingly important in almost all scientific domains, especially in geoscience where hundreds to millions of sensors are collecting data of the Earth continuously (Whitehouse News 2012). With the explosive growth of data, various Geospatial Cyberinfrastructure (GCI) (Yang et al. 2010) components are developed to manage geospatial resources and provide data access for the public. These GCIs are accessed by different users intensively on a daily basis. However, little research has been done to analyze the spatiotemporal patterns of user behavior, which could be critical to the management of Big Data and the operation of GCIs (Yang et al. 2011). For example, the spatiotemporal distribution of end users helps us better arrange and locate GCI computing facilities. A better indexing and caching mechanism could be developed based on the spatiotemporal pattern of user queries. In this paper, we use GEOSS Clearinghouse as an example to investigate spatiotemporal patterns of user behavior in GCIs. The investigation results show that user behaviors are heterogeneous but with patterns across space and time. Identified patterns include (1) the high access frequency regions; (2) local interests; (3) periodical accesses and rush hours; (4) spiking access. Based on identified patterns, this presentation reports several solutions to better support the operation of the GEOSS Clearinghouse and other GCIs.

VFC: The Vienna Fortran Compiler

Directory of Open Access Journals (Sweden)

Siegfried Benkner

1999-01-01

Full Text Available High Performance Fortran (HPF offers an attractive high‐level language interface for programming scalable parallel architectures providing the user with directives for the specification of data distribution and delegating to the compiler the task of generating an explicitly parallel program. Available HPF compilers can handle regular codes quite efficiently, but dramatic performance losses may be encountered for applications which are based on highly irregular, dynamically changing data structures and access patterns. In this paper we introduce the Vienna Fortran Compiler (VFC, a new source‐to‐source parallelization system for HPF+, an optimized version of HPF, which addresses the requirements of irregular applications. In addition to extended data distribution and work distribution mechanisms, HPF+ provides the user with language features for specifying certain information that decisively influence a program’s performance. This comprises data locality assertions, non‐local access specifications and the possibility of reusing runtime‐generated communication schedules of irregular loops. Performance measurements of kernels from advanced applications demonstrate that with a high‐level data parallel language such as HPF+ a performance close to hand‐written message‐passing programs can be achieved even for highly irregular codes.

Alvis is a formal modelling language that enables possibility of verification of distributed concurrent systems. An Alvis model semantics finds expression in an LTS graph (labelled transition system). Execution of any language statement is expressed as a transition between formally defined states of such a model. An LTS graph is generated using a middle-stage Haskell representation of an Alvis model. Moreover, Haskell is used as a part of the Alvis language and is used to define parameters’ types and operations on them. Thanks to the compiler’s modular construction many aspects of compilation of an Alvis model may be modified. Providing new plugins for Alvis Compiler that support languages like Java or C makes possible using these languages as a part of Alvis instead of Haskell. The paper presents the compiler internal model and describes how the default specification language can be altered by new plugins.

The national assessment of shoreline change: a GIS compilation of vector cliff edges and associated cliff erosion data for the California coast

Hapke, Cheryl; Reid, David; Borrelli, Mark

2007-01-01

The U.S. Geological Survey has generated a comprehensive data clearinghouse of digital vector cliff edges and associated rates of cliff retreat along the open-ocean California coast. These data, which are presented herein, were compiled as part of the U.S. Geological Survey's National Assessment of Shoreline Change Project. Cliff erosion is a chronic problem along many coastlines of the United States. As coastal populations continue to grow and community infrastructures are threatened by erosion, there is increased demand for accurate information including rates and trends of coastal cliff retreat. There is also a critical need for these data to be consistent from one region to another. One objective of this work is to a develop standard, repeatable methodology for mapping and analyzing cliff edge retreat so that periodic, systematic, and internally consistent updates of cliff edge position and associated rates of erosion can be made at a national scale. This data compilation for open-ocean cliff edges for the California coast is a separate, yet related study to Hapke and others, 2006 documenting shoreline change along sandy shorelines of the California coast, which is itself one in a series that includes the Gulf of Mexico and the Southeast Atlantic coast (Morton and others, 2004; Morton and Miller, 2005). Future reports and data compilations will include coverage of the Northeast U.S., the Great Lakes, Hawaii and Alaska. Cliff edge change is determined by comparing the positions of one historical cliff edge digitized from maps with a modern cliff edge derived from topographic LIDAR (light detection and ranging) surveys. Historical cliff edges for the California coast represent the 1920s-1930s time-period; the most recent cliff edge was delineated using data collected between 1998 and 2002. End-point rate calculations were used to evaluate rates of erosion between the two cliff edges. Please refer to our full report on cliff edge erosion along the California

The proof is highly non-trivial because both the ARMv8 POP and the promising semantics provide some extremely weak consistency guarantees for normal memory accesses; however, they do so in rather different ways. Our proof of compilation correctness to ARMv8 POP strengthens the results of the Kan...

Design of methodology for incremental compiler construction

Directory of Open Access Journals (Sweden)

Pavel Haluza

2011-01-01

Full Text Available The paper deals with possibilities of the incremental compiler construction. It represents the compiler construction possibilities for languages with a fixed set of lexical units and for languages with a variable set of lexical units, too. The methodology design for the incremental compiler construction is based on the known algorithms for standard compiler construction and derived for both groups of languages. Under the group of languages with a fixed set of lexical units there belong languages, where each lexical unit has its constant meaning, e.g., common programming languages. For this group of languages the paper tries to solve the problem of the incremental semantic analysis, which is based on incremental parsing. In the group of languages with a variable set of lexical units (e.g., professional typographic system TEX, it is possible to change arbitrarily the meaning of each character on the input file at any time during processing. The change takes effect immediately and its validity can be somehow limited or is given by the end of the input. For this group of languages this paper tries to solve the problem case when we use macros temporarily changing the category of arbitrary characters.

Méthodes Il s'agit d'une étude descriptive transversale réalisée sur une période de 9 mois entre septembre 2010 et juin 2011, dans le service de bactériologie de l'hôpital militaire d'Instruction Mohammed V. Résultats L’étude bactériologique a été faite sur 240 téléphones mobiles dont 50% provenaient de personnels de sante. Le taux de contamination bactérienne de tous les téléphones mobiles était de 100%. Les cultures des bactéries isolées au niveau des téléphones mobiles du personnel médical étaient plus polymorphes que celles de la population témoin (p=0,028). Parmi 437 bactéries isolées: 223(51%) provenaient de téléphones de personnels de santé et 214(49%) de téléphones de la population témoin avec une différence qui n’était pas statistiquement significative(p>0,05) sauf pour les isolats de Staphylocoque à coagulase négative et Staphylococcus aureus. Les bactéries isolées étaient représentées par: Staphylocoque à coagulase (57,7%), Staphylococcus aureus (18,1%), Corynebacterium sp (18,8%), Bacillus sp (2,3%) et autres (2,2%). La différence entre la prévalence des bactéries isolées selon les services et les fonctions des personnels de santé n’était pas statistiquement significative (p>0,05). La désinfection des téléphones portables par la solution hydroalcoolique a réduit à 99,5% le nombre des colonies. Conclusion Ce travail montre que les téléphones portables pourraient jouer un rôle dans la transmission des infections nosocomiales et communautaires.

Abstract: In this research article a study is made of the approach followed to compile the first-ever monolingual dictionary for Lusoga. Lusoga is a Bantu language spoken in Uganda by slightly over two mil-lion people. Being an under-resourced language, the Lusoga orthography had to be designed, a grammar written, and a corpus built, before embarking on the compilation of the dictionary. This compilation was aimed at attaining an academic degree, hence requiring a rigorous research methodology. Firstly, the prevail-ing methods for compiling dictionaries were mainly practical and insufficient in explaining the theoretical linguistic basis for dictionary compilation. Since dictionaries are based on meaning, the theory of meaning was used to account for all linguistic data considered in dictionaries. However, meaning is considered at a very abstract level, far removed from the process of compiling dictionaries. Another theory, the theory of modularity, was used to bridge the gap between the theory of meaning and the compilation process. The modular theory explains how the different modules of a language contribute information to the different parts of the dictionary article or dictionary information in general. Secondly, the research also had to contend with the different approaches for analysing Bantu languages for Bantu and European audiences. A descrip-tion of the Bantu- and European-centred approaches to Bantu studies was undertaken in respect of (a the classification of Lusoga words, and (b the specification of their citations. As a result, Lusoga lexicography deviates from the prevailing Bantu classification and citation of nouns, adjectives and verbs in particular. The dictionary was tested on two separate occasions and all the feedback was considered in the compilation pro-cess. This article, then, gives an overall summary of all the steps involved in the compilation of the Eiwanika ly'Olusoga, i.e. the Monolingual Lusoga Dictionary

Full Text Available The development of single chip VLSI processors is the key technology of ever growing pervasive computing to answer overall demands for usability, mobility, speed, security, etc. We have so far developed a hardware cryptography-embedded multimedia mobile processor architecture, HCgorilla. Since HCgorilla integrates a wide range of techniques from architectures to applications and languages, one-sided design approach is not always useful. HCgorilla needs more complicated strategy, that is, hardware/software (H/S codesign. Thus, we exploit the software support of HCgorilla composed of a Java interface and parallelizing compilers. They are assumed to be installed in servers in order to reduce the load and increase the performance of HCgorilla-embedded clients. Since compilers are the essence of software's responsibility, we focus in this article on our recent results about the design, specifications, and prototyping of parallelizing compilers for HCgorilla. The parallelizing compilers are composed of a multicore compiler and a LIW compiler. They are specified to abstract parallelism from executable serial codes or the Java interface output and output the codes executable in parallel by HCgorilla. The prototyping compilers are written in Java. The evaluation by using an arithmetic test program shows the reasonability of the prototyping compilers compared with hand compilers.

Automatic Loop Parallelization via Compiler Guided Refactoring

DEFF Research Database (Denmark)

Larsen, Per; Ladelsky, Razya; Lidman, Jacob

For many parallel applications, performance relies not on instruction-level parallelism, but on loop-level parallelism. Unfortunately, many modern applications are written in ways that obstruct automatic loop parallelization. Since we cannot identify sufficient parallelization opportunities...... for these codes in a static, off-line compiler, we developed an interactive compilation feedback system that guides the programmer in iteratively modifying application source, thereby improving the compiler’s ability to generate loop-parallel code. We use this compilation system to modify two sequential...... benchmarks, finding that the code parallelized in this way runs up to 8.3 times faster on an octo-core Intel Xeon 5570 system and up to 12.5 times faster on a quad-core IBM POWER6 system. Benchmark performance varies significantly between the systems. This suggests that semi-automatic parallelization should...

Efetuou-se o levantamento de leguminosas no Parque Estadual de Campos do Jordão e o isolamento de bactérias dos nódulos radiculares destas plantas, seguido da caracterização fenotípica dos isolados. As bactérias dos nódulos foram isoladas em meio de cultura YMA, sendo classificadas de acordo com suas características de crescimento (velocidade de crescimento, cor, produção de polissacarídeo extracelular e mudança de pH do meio. Os resultados foram analisados por análise de agrupamento e análise de componentes principais (PCA. De um total de onze espécies de leguminosas, nove apresentaram nódulos, sendo seis espécies descritas como nodulantes pela primeira vez. Duzentas e doze estirpes de bactérias foram isoladas, havendo variação no formato de nódulos e alta riqueza fenotípica das bactérias isoladas. Essa riqueza ocorreu entre as espécies de leguminosas, entre indivíduos da mesma espécie, entre diferentes formatos de nódulos e, inclusive, entre bactérias isoladas de um mesmo nódulo. As bactérias puderam ser classificadas em vários grupos, de dois a seis de acordo com cada leguminosa, a maioria deles diferentes de Rhizobium tropici, Bradyrhizobium elkanii e Burkholderia sp., que foram utilizados como padrões de crescimento. Existem algumas evidências de que estes grupos distintos podem estar relacionados à presença de Burkholderia spp. nos nódulos destas leguminosas.

On a sollicité les commentaires d’experts en la matière venant de l’extérieur, ainsi que l’aval de sociétés médicales canadiennes (Association pour la microbiologie médicale et l’infectiologie Canada, Société canadienne d’allergie et d’immunologie clinique, Société canadienne d’otorhinolaryngologie et de chirurgie cervicofaciale, Association canadienne des médecins d’urgence et Regroupement canadien des médecins de famille en santé respiratoire). Message principal Le diagnostic de la RSBA repose sur la présence de symptômes particuliers et leur durée; l’imagerie ou une culture n’est pas nécessaire dans les cas peu compliqués. Le traitement dépend de la gravité des symptômes, notamment avec des corticostéroïdes intranasaux (CSIN) recommandés comme monothérapie pour les cas de légers à modérés, quoique leurs bienfaits soient modestes. Le recours à des CSIN accompagnés d’antibiotiques est réservé aux patients qui ne répondent pas aux CSIN après 72 heures et comme traitement initial des patients dont les symptômes sont graves. Le choix de l’antibiotique doit tenir compte du pathogène soupçonné, du risque de résistance, des problèmes concomitants et des tendances locales de la résistance aux antimicrobiens. Des thérapies d’appoint comme l’irrigation nasale avec une solution saline sont recommandées. En présence de cas réfractaires au traitement, d’épisodes récurrents et de signes de complications, on devrait demander une

Full Text Available Suppression of plant diseases due to the action of endophytic microorganisms has been demonstrated in several pathosystems. Experiments under controlled conditions involving endophytic bacteria isolated from leaves and branches of Coffea arabica L and Coffea robusta L were conducted with the objective of evaluating the inhibition of germination of Hemileia vastatrix Berk. & Br., race II, urediniospores and the control of coffee leaf rust development in tests with leaf discs, detached leaves, and on potted seedling of cv. Mundo Novo. The endophytic bacterial isolates tested proved to be effective in inhibiting urediniospore germination and/or rust development, with values above 50%, although the results obtained in urediniospore germination tests were inferior to the treatment with fungicide propiconazole. Endophytic isolates TG4-Ia, TF2-IIc, TF9-Ia, TG11-IIa, and TF7-IIa, demonstrated better coffee leaf rust control in leaf discs, detached leaves, and coffee plant tests. The endophytic isolates TG4-Ia and TF9-Ia were identified as Bacillus lentimorbus Dutky and Bacillus cereus Frank. & Frank., respectively. Some endophytic bacterial isolates were effective in controlling the coffee leaf rust, although some increased the severity of the disease. Even though a relatively small number of endophytic bacteria were tested, promising results were obtained regarding the efficiency of coffee leaf rust biocontrol. These selected agents appears to be an alternative for future replacement of chemical fungicide.Supressão de doenças de plantas por microrganismos endofíticos tem sido demonstrada em diversos patossistemas.

As bactérias BR11417 (Herbaspirillum seropedicae e BR11340 (Burkholderia sp., foram multiplicadas por um período de 24 horas e uma alíquota de 10 mL com 10(8 cel. mL-1 foi transferida para sacos de polipropileno contendo 35 g de turfa. Foram adicionadas duas doses e duas fontes de molibdênio: 1,12 e 2,25 g de molibdato de sódio e de amônio, respectivamente. Como controle, foi utilizado o inoculante sem molibdênio. A legislação brasileira, por meio da lei n° 86955, especifica que os inoculantes comerciais à base de micro-organismos fixadores de nitrogênio apresentem concentrações mínimas de 10(8 células viáveis por grama do produto no momento do uso e que a viabilidade das células seja mantida por um período mínimo de seis meses. Este estudo mostrou que sem a adição do molibdênio ao inoculante, as bactérias sobreviveram com um número de células viáveis em torno de 10(8 células g-1 de inoculante, por um período de até 110 dias. Com a adição do molibdênio, o inoculante manteve-se viável por um período de 180 dias.

Compiled MPI: Cost-Effective Exascale Applications Development

Energy Technology Data Exchange (ETDEWEB)

Bronevetsky, G; Quinlan, D; Lumsdaine, A; Hoefler, T

2012-04-10

The complexity of petascale and exascale machines makes it increasingly difficult to develop applications that can take advantage of them. Future systems are expected to feature billion-way parallelism, complex heterogeneous compute nodes and poor availability of memory (Peter Kogge, 2008). This new challenge for application development is motivating a significant amount of research and development on new programming models and runtime systems designed to simplify large-scale application development. Unfortunately, DoE has significant multi-decadal investment in a large family of mission-critical scientific applications. Scaling these applications to exascale machines will require a significant investment that will dwarf the costs of hardware procurement. A key reason for the difficulty in transitioning today's applications to exascale hardware is their reliance on explicit programming techniques, such as the Message Passing Interface (MPI) programming model to enable parallelism. MPI provides a portable and high performance message-passing system that enables scalable performance on a wide variety of platforms. However, it also forces developers to lock the details of parallelization together with application logic, making it very difficult to adapt the application to significant changes in the underlying system. Further, MPI's explicit interface makes it difficult to separate the application's synchronization and communication structure, reducing the amount of support that can be provided by compiler and run-time tools. This is in contrast to the recent research on more implicit parallel programming models such as Chapel, OpenMP and OpenCL, which promise to provide significantly more flexibility at the cost of reimplementing significant portions of the application. We are developing CoMPI, a novel compiler-driven approach to enable existing MPI applications to scale to exascale systems with minimal modifications that can be made incrementally over

Solidify, An LLVM pass to compile LLVM IR into Solidity

Energy Technology Data Exchange (ETDEWEB)

2017-07-12

The software currently compiles LLVM IR into Solidity (Ethereum’s dominant programming language) using LLVM’s pass library. Specifically, his compiler allows us to convert an arbitrary DSL into Solidity. We focus specifically on converting Domain Specific Languages into Solidity due to their ease of use, and provable properties. By creating a toolchain to compile lightweight domain-specific languages into Ethereum's dominant language, Solidity, we allow non-specialists to effectively develop safe and useful smart contracts. For example lawyers from a certain firm can have a proprietary DSL that codifies basic laws safely converted to Solidity to be securely executed on the blockchain. In another example, a simple provenance tracking language can be compiled and securely executed on the blockchain.

Compiler-Assisted Multiple Instruction Rollback Recovery Using a Read Buffer. Ph.D. Thesis

Science.gov (United States)

Alewine, Neal Jon

1993-01-01

Multiple instruction rollback (MIR) is a technique to provide rapid recovery from transient processor failures and was implemented in hardware by researchers and slow in mainframe computers. Hardware-based MIR designs eliminate rollback data hazards by providing data redundancy implemented in hardware. Compiler-based MIR designs were also developed which remove rollback data hazards directly with data flow manipulations, thus eliminating the need for most data redundancy hardware. Compiler-assisted techniques to achieve multiple instruction rollback recovery are addressed. It is observed that data some hazards resulting from instruction rollback can be resolved more efficiently by providing hardware redundancy while others are resolved more efficiently with compiler transformations. A compiler-assisted multiple instruction rollback scheme is developed which combines hardware-implemented data redundancy with compiler-driven hazard removal transformations. Experimental performance evaluations were conducted which indicate improved efficiency over previous hardware-based and compiler-based schemes. Various enhancements to the compiler transformations and to the data redundancy hardware developed for the compiler-assisted MIR scheme are described and evaluated. The final topic deals with the application of compiler-assisted MIR techniques to aid in exception repair and branch repair in a speculative execution architecture.

An Extensible Open-Source Compiler Infrastructure for Testing

Energy Technology Data Exchange (ETDEWEB)

Quinlan, D; Ur, S; Vuduc, R

2005-12-09

Testing forms a critical part of the development process for large-scale software, and there is growing need for automated tools that can read, represent, analyze, and transform the application's source code to help carry out testing tasks. However, the support required to compile applications written in common general purpose languages is generally inaccessible to the testing research community. In this paper, we report on an extensible, open-source compiler infrastructure called ROSE, which is currently in development at Lawrence Livermore National Laboratory. ROSE specifically targets developers who wish to build source-based tools that implement customized analyses and optimizations for large-scale C, C++, and Fortran90 scientific computing applications (on the order of a million lines of code or more). However, much of this infrastructure can also be used to address problems in testing, and ROSE is by design broadly accessible to those without a formal compiler background. This paper details the interactions between testing of applications and the ways in which compiler technology can aid in the understanding of those applications. We emphasize the particular aspects of ROSE, such as support for the general analysis of whole programs, that are particularly well-suited to the testing research community and the scale of the problems that community solves.

Full Text Available The aim of this study was to characterize keratinolytic bacteria isolated from feather waste. Four isolates were selected after growth on solid medium with feather meal as sole carbon and nitrogen source and screened for proteolytic activity on milk agar plates. Three isolates were Gram-negative (belonged to the genera Burkholderia, Chryseobacterium and Pseudomonas and one was Gram-positive (Microbacterium sp.. These bacteria grew on diverse keratin wastes such as feather meal, raw feathers, chicken nails, hair and wool. Keratinase activity was detected during growth, but the complete degradation of these substrates was not always achieved. The proteolytic character of crude enzymes was assessed using azokeratin and azocasein as substrates. The keratinases were active on both substrates and were similar in keratin hydrolysis when compared with commercially available microbial peptidases. These novel keratinolytic isolates have potential biotechnological use in processes involving keratin hydrolysis.O objetivo deste estudo foi caracterizar bactérias queratinolíticas isoladas resíduos de penas.

Full Text Available RESUMO A cana-de-açúcar é uma cultura de grande destaque na economia, em razão da produção de açúcar, etanol e energia. Tecnologias que possam contribuir para o aumento da produtividade e qualidade da cultura com mínimos danos ao meio ambiente são necessárias. Objetivou-se avaliar a produção de ácido indol acético de cinco estirpes de bactérias diazotróficas e o efeito da inoculação delas na brotação de duas variedades de cana-de-açúcar, RB867515 e IACSP95-5000. A produção de auxina foi determinada pelo teste colorimétrico, usando o reagente de Salkowski. Para avaliar a germinação, foi conduzido um experimento em casa de vegetação, utilizando-se delineamento experimental em blocos ao acaso com quatro repetições e sete tratamentos: controle não inoculado; inoculação mista com as cinco estirpes e inoculação individual com Gluconacetobacter diazotrophicus (Gd estirpe BR11281T(PAL-5T, Herbaspirillum seropedicae (Hs - BR11335 = HRC54, Herbaspirillum rubrisubalbicans (Hr - BR11504 = HCC103, Burkholderia tropica (Bt - BR11366T = PPe 8 T e Azospirillum amazonense (Aa - BR11145 = CBAMc. As bactérias mais eficientes na produção de auxina foram Hs e Hr, declinando 48 h após o crescimento. Hr, Aa e Bt aumentaram o índice de velocidade de germinação e o número de brotações nas duas variedades. Na var. RB867515, a velocidade de germinação ainda foi positivamente influenciada pela inoculação mista, sendo o mesmo observado pela inoculação de Gd na var. IACSP95-5000.

Automating Visualization Service Generation with the WATT Compiler

Science.gov (United States)

Bollig, E. F.; Lyness, M. D.; Erlebacher, G.; Yuen, D. A.

2007-12-01

As tasks and workflows become increasingly complex, software developers are devoting increasing attention to automation tools. Among many examples, the Automator tool from Apple collects components of a workflow into a single script, with very little effort on the part of the user. Tasks are most often described as a series of instructions. The granularity of the tasks dictates the tools to use. Compilers translate fine-grained instructions to assembler code, while scripting languages (ruby, perl) are used to describe a series of tasks at a higher level. Compilers can also be viewed as transformational tools: a cross-compiler can translate executable code written on one computer to assembler code understood on another, while transformational tools can translate from one high-level language to another. We are interested in creating visualization web services automatically, starting from stand-alone VTK (Visualization Toolkit) code written in Tcl. To this end, using the OCaml programming language, we have developed a compiler that translates Tcl into C++, including all the stubs, classes and methods to interface with gSOAP, a C++ implementation of the Soap 1.1/1.2 protocols. This compiler, referred to as the Web Automation and Translation Toolkit (WATT), is the first step towards automated creation of specialized visualization web services without input from the user. The WATT compiler seeks to automate all aspects of web service generation, including the transport layer, the division of labor and the details related to interface generation. The WATT compiler is part of ongoing efforts within the NSF funded VLab consortium [1] to facilitate and automate time-consuming tasks for the science related to understanding planetary materials. Through examples of services produced by WATT for the VLab portal, we will illustrate features, limitations and the improvements necessary to achieve the ultimate goal of complete and transparent automation in the generation of web

Charged particle induced thermonuclear reaction rates: a compilation for astrophysics

International Nuclear Information System (INIS)

Grama, C.

1999-01-01

We report on the results of the European network NACRE (Nuclear Astrophysics Compilation of REaction rates). The principal reason for setting up the NACRE network has been the necessity of building up a well-documented and detailed compilation of rates for charged-particle induced reactions on stable targets up to Si and on unstable nuclei of special significance in astrophysics. This work is meant to supersede the only existing compilation of reaction rates issued by Fowler and collaborators. The main goal of NACRE network was the transparency in the procedure of calculating the rates. More specifically this compilation aims at: 1. updating the experimental and theoretical data; 2. distinctly identifying the sources of the data used in rate calculation; 3. evaluating the uncertainties and errors; 4. providing numerically integrated reaction rates; 5. providing reverse reaction rates and analytical approximations of the adopted rates. The cross section data and/or resonance parameters for a total of 86 charged-particle induced reactions are given and the corresponding reaction rates are calculated and given in tabular form. Uncertainties are analyzed and realistic upper and lower bounds of the rates are determined. The compilation is concerned with the reaction rates that are large enough for the target lifetimes shorter than the age of the Universe, taken equal to 15 x 10 9 y. The reaction rates are provided for temperatures lower than T = 10 10 K. In parallel with the rate compilation a cross section data base has been created and located at the site http://pntpm.ulb.ac.be/nacre..htm. (authors)

Nuclear reaction data are essential for research and development in nuclear engineering, radiation therapy, nuclear physics and astrophysics. Experimental data must be compiled in a database and be accessible to nuclear data users. One of the nuclear reaction databases is the EXFOR database maintained by the International Network of Nuclear Reaction Data Centres (NRDC) under the auspices of the International Atomic Energy Agency. Recently, collaboration among the Asian NRDC members is being further developed under the support of the Asia-Africa Science Platform Program of the Japan Society for the Promotion of Science. We report the activity for three years to develop the Asian collaboration on nuclear reaction data compilation. (author)

Fault-tolerant digital microfluidic biochips compilation and synthesis

CERN Document Server

Pop, Paul; Stuart, Elena; Madsen, Jan

2016-01-01

This book describes for researchers in the fields of compiler technology, design and test, and electronic design automation the new area of digital microfluidic biochips (DMBs), and thus offers a new application area for their methods.  The authors present a routing-based model of operation execution, along with several associated compilation approaches, which progressively relax the assumption that operations execute inside fixed rectangular modules.  Since operations can experience transient faults during the execution of a bioassay, the authors show how to use both offline (design time) and online (runtime) recovery strategies. The book also presents methods for the synthesis of fault-tolerant application-specific DMB architectures. ·         Presents the current models used for the research on compilation and synthesis techniques of DMBs in a tutorial fashion; ·         Includes a set of “benchmarks”, which are presented in great detail and includes the source code of most of the t...

PGHPF – An Optimizing High Performance Fortran Compiler for Distributed Memory Machines

Directory of Open Access Journals (Sweden)

Zeki Bozkus

1997-01-01

Full Text Available High Performance Fortran (HPF is the first widely supported, efficient, and portable parallel programming language for shared and distributed memory systems. HPF is realized through a set of directive-based extensions to Fortran 90. It enables application developers and Fortran end-users to write compact, portable, and efficient software that will compile and execute on workstations, shared memory servers, clusters, traditional supercomputers, or massively parallel processors. This article describes a production-quality HPF compiler for a set of parallel machines. Compilation techniques such as data and computation distribution, communication generation, run-time support, and optimization issues are elaborated as the basis for an HPF compiler implementation on distributed memory machines. The performance of this compiler on benchmark programs demonstrates that high efficiency can be achieved executing HPF code on parallel architectures.

A survey of compiler development aids. [concerning lexical, syntax, and semantic analysis

Science.gov (United States)

Buckles, B. P.; Hodges, B. C.; Hsia, P.

1977-01-01

A theoretical background was established for the compilation process by dividing it into five phases and explaining the concepts and algorithms that underpin each. The five selected phases were lexical analysis, syntax analysis, semantic analysis, optimization, and code generation. Graph theoretical optimization techniques were presented, and approaches to code generation were described for both one-pass and multipass compilation environments. Following the initial tutorial sections, more than 20 tools that were developed to aid in the process of writing compilers were surveyed. Eight of the more recent compiler development aids were selected for special attention - SIMCMP/STAGE2, LANG-PAK, COGENT, XPL, AED, CWIC, LIS, and JOCIT. The impact of compiler development aids were assessed some of their shortcomings and some of the areas of research currently in progress were inspected.

The Katydid system for compiling KEE applications to Ada

Science.gov (United States)

Filman, Robert E.; Bock, Conrad; Feldman, Roy

1990-01-01

Components of a system known as Katydid are developed in an effort to compile knowledge-based systems developed in a multimechanism integrated environment (KEE) to Ada. The Katydid core is an Ada library supporting KEE object functionality, and the other elements include a rule compiler, a LISP-to-Ada translator, and a knowledge-base dumper. Katydid employs translation mechanisms that convert LISP knowledge structures and rules to Ada and utilizes basic prototypes of a run-time KEE object-structure library module for Ada. Preliminary results include the semiautomatic compilation of portions of a simple expert system to run in an Ada environment with the described algorithms. It is suggested that Ada can be employed for AI programming and implementation, and the Katydid system is being developed to include concurrency and synchronization mechanisms.

Proceedings of the workshop on Compilation of (Symbolic) Languages for Parallel Computers

Energy Technology Data Exchange (ETDEWEB)

Foster, I.; Tick, E. (comp.)

1991-11-01

This report comprises the abstracts and papers for the talks presented at the Workshop on Compilation of (Symbolic) Languages for Parallel Computers, held October 31--November 1, 1991, in San Diego. These unreferred contributions were provided by the participants for the purpose of this workshop; many of them will be published elsewhere in peer-reviewed conferences and publications. Our goal is planning this workshop was to bring together researchers from different disciplines with common problems in compilation. In particular, we wished to encourage interaction between researchers working in compilation of symbolic languages and those working on compilation of conventional, imperative languages. The fundamental problems facing researchers interested in compilation of logic, functional, and procedural programming languages for parallel computers are essentially the same. However, differences in the basic programming paradigms have led to different communities emphasizing different species of the parallel compilation problem. For example, parallel logic and functional languages provide dataflow-like formalisms in which control dependencies are unimportant. Hence, a major focus of research in compilation has been on techniques that try to infer when sequential control flow can safely be imposed. Granularity analysis for scheduling is a related problem. The single- assignment property leads to a need for analysis of memory use in order to detect opportunities for reuse. Much of the work in each of these areas relies on the use of abstract interpretation techniques.

Dose calculation with respiration-averaged CT processed from cine CT without a respiratory surrogate

International Nuclear Information System (INIS)

Riegel, Adam C.; Ahmad, Moiz; Sun Xiaojun; Pan Tinsu

2008-01-01

Dose calculation for thoracic radiotherapy is commonly performed on a free-breathing helical CT despite artifacts caused by respiratory motion. Four-dimensional computed tomography (4D-CT) is one method to incorporate motion information into the treatment planning process. Some centers now use the respiration-averaged CT (RACT), the pixel-by-pixel average of the ten phases of 4D-CT, for dose calculation. This method, while sparing the tedious task of 4D dose calculation, still requires 4D-CT technology. The authors have recently developed a means to reconstruct RACT directly from unsorted cine CT data from which 4D-CT is formed, bypassing the need for a respiratory surrogate. Using RACT from cine CT for dose calculation may be a means to incorporate motion information into dose calculation without performing 4D-CT. The purpose of this study was to determine if RACT from cine CT can be substituted for RACT from 4D-CT for the purposes of dose calculation, and if increasing the cine duration can decrease differences between the dose distributions. Cine CT data and corresponding 4D-CT simulations for 23 patients with at least two breathing cycles per cine duration were retrieved. RACT was generated four ways: First from ten phases of 4D-CT, second, from 1 breathing cycle of images, third, from 1.5 breathing cycles of images, and fourth, from 2 breathing cycles of images. The clinical treatment plan was transferred to each RACT and dose was recalculated. Dose planes were exported at orthogonal planes through the isocenter (coronal, sagittal, and transverse orientations). The resulting dose distributions were compared using the gamma (γ) index within the planning target volume (PTV). Failure criteria were set to 2%/1 mm. A follow-up study with 50 additional lung cancer patients was performed to increase sample size. The same dose recalculation and analysis was performed. In the primary patient group, 22 of 23 patients had 100% of points within the PTV pass γ criteria

Seleção de bactérias promotoras de crescimento no abacaxizeiro cultivar Vitória durante a aclimatização Selection of growth-promoting bacteria for pineapple 'Vitória' during acclimatization

Full Text Available A propagação in vitro do abacaxizeiro (Ananas comosus L. Merril resulta na produção de uma grande quantidade de mudas sadias e homogêneas. Apesar dessas vantagens, a necessidade de um longo período de aclimatização onera essa prática agrícola. A aceleração do crescimento das plantas pela inoculação de bactérias diazotróficas endofíticas e epifíticas pode ser útil para diminuir esse período. O objetivo deste trabalho foi avaliar o potencial de 20 estirpes de bactérias diazotróficas em sintetizar indol, solubilizar fosfato de Ca e óxido de Zn e atuar antagonicamente ao fungo fitopatogênico Fusarium subglutinans f. sp. ananas, bem como, posteriormente, avaliar o desempenho do abacaxizeiro 'Vitória' propagado por cultura de tecidos em resposta à inoculação bacteriana durante o período de aclimatização em casa de vegetação.

Transportation legislative data base: State radioactive materials transportation statute compilation, 1989--1993

International Nuclear Information System (INIS)

1994-04-01

The Transportation Legislative Data Base (TLDB) is a computer-based information service containing summaries of federal, state and certain local government statutes and regulations relating to the transportation of radioactive materials in the United States. The TLDB has been operated by the National Conference of State Legislatures (NCSL) under cooperative agreement with the US Department of Energy's (DOE) Office of Civilian Radioactive Waste Management since 1992. The data base system serves the legislative and regulatory information needs of federal, state, tribal and local governments, the affected private sector and interested members of the general public. Users must be approved by DOE and NCSL. This report is a state statute compilation that updates the 1989 compilation produced by Battelle Memorial Institute, the previous manager of the data base. This compilation includes statutes not included in the prior compilation, as well as newly enacted laws. Statutes not included in the prior compilation show an enactment date prior to 1989. Statutes that deal with low-level radioactive waste transportation are included in the data base as are statutes from the states of Alaska and Hawaii. Over 155 new entries to the data base are summarized in this compilation

A Language for Specifying Compiler Optimizations for Generic Software

Energy Technology Data Exchange (ETDEWEB)

Willcock, Jeremiah J. [Indiana Univ., Bloomington, IN (United States)

2007-01-01

Compiler optimization is important to software performance, and modern processor architectures make optimization even more critical. However, many modern software applications use libraries providing high levels of abstraction. Such libraries often hinder effective optimization — the libraries are difficult to analyze using current compiler technology. For example, high-level libraries often use dynamic memory allocation and indirectly expressed control structures, such as iteratorbased loops. Programs using these libraries often cannot achieve an optimal level of performance. On the other hand, software libraries have also been recognized as potentially aiding in program optimization. One proposed implementation of library-based optimization is to allow the library author, or a library user, to define custom analyses and optimizations. Only limited systems have been created to take advantage of this potential, however. One problem in creating a framework for defining new optimizations and analyses is how users are to specify them: implementing them by hand inside a compiler is difficult and prone to errors. Thus, a domain-specific language for librarybased compiler optimizations would be beneficial. Many optimization specification languages have appeared in the literature, but they tend to be either limited in power or unnecessarily difficult to use. Therefore, I have designed, implemented, and evaluated the Pavilion language for specifying program analyses and optimizations, designed for library authors and users. These analyses and optimizations can be based on the implementation of a particular library, its use in a specific program, or on the properties of a broad range of types, expressed through concepts. The new system is intended to provide a high level of expressiveness, even though the intended users are unlikely to be compiler experts.

Compilation of piping benchmark problems - Cooperative international effort

Energy Technology Data Exchange (ETDEWEB)

McAfee, W J [comp.

1979-06-01

This report is the culmination of an effort initiated in 1976 by the IWGFR to evaluate detailed and simplified analysis methods for piping systems with particular emphasis on piping bends. The procedure was to collect from participating member IWGFR countries descriptions of tests and test results for piping systems or bends, to compile, evaluate, and issue a selected number of these problems for analysis, and to compile and make a preliminary evaluation of the analysis results. The Oak Ridge National Laboratory agreed to coordinate this activity, including compilation of the original problems and the final analyses results. Of the problem descriptions submitted three were selected to be used. These were issued in December 1977. As a follow-on activity, addenda were issued that provided additional data or corrections to the original problem statement. A variety of both detailed and simplified analysis solutions were obtained. A brief comparative assessment of the analyses is contained in this report. All solutions submitted have also been included in order to provide users of this report the information necessary to make their own comparisons or evaluations.

Compiling knowledge-based systems from KEE to Ada

Science.gov (United States)

Filman, Robert E.; Bock, Conrad; Feldman, Roy

1990-01-01

The dominant technology for developing AI applications is to work in a multi-mechanism, integrated, knowledge-based system (KBS) development environment. Unfortunately, systems developed in such environments are inappropriate for delivering many applications - most importantly, they carry the baggage of the entire Lisp environment and are not written in conventional languages. One resolution of this problem would be to compile applications from complex environments to conventional languages. Here the first efforts to develop a system for compiling KBS developed in KEE to Ada (trademark). This system is called KATYDID, for KEE/Ada Translation Yields Development Into Delivery. KATYDID includes early prototypes of a run-time KEE core (object-structure) library module for Ada, and translation mechanisms for knowledge structures, rules, and Lisp code to Ada. Using these tools, part of a simple expert system was compiled (not quite automatically) to run in a purely Ada environment. This experience has given us various insights on Ada as an artificial intelligence programming language, potential solutions of some of the engineering difficulties encountered in early work, and inspiration on future system development.

Perspex machine: V. Compilation of C programs

Science.gov (United States)

Spanner, Matthew P.; Anderson, James A. D. W.

2006-01-01

The perspex machine arose from the unification of the Turing machine with projective geometry. The original, constructive proof used four special, perspective transformations to implement the Turing machine in projective geometry. These four transformations are now generalised and applied in a compiler, implemented in Pop11, that converts a subset of the C programming language into perspexes. This is interesting both from a geometrical and a computational point of view. Geometrically, it is interesting that program source can be converted automatically to a sequence of perspective transformations and conditional jumps, though we find that the product of homogeneous transformations with normalisation can be non-associative. Computationally, it is interesting that program source can be compiled for a Reduced Instruction Set Computer (RISC), the perspex machine, that is a Single Instruction, Zero Exception (SIZE) computer.

Compiling gate networks on an Ising quantum computer

International Nuclear Information System (INIS)

Bowdrey, M.D.; Jones, J.A.; Knill, E.; Laflamme, R.

2005-01-01

Here we describe a simple mechanical procedure for compiling a quantum gate network into the natural gates (pulses and delays) for an Ising quantum computer. The aim is not necessarily to generate the most efficient pulse sequence, but rather to develop an efficient compilation algorithm that can be easily implemented in large spin systems. The key observation is that it is not always necessary to refocus all the undesired couplings in a spin system. Instead, the coupling evolution can simply be tracked and then corrected at some later time. Although described within the language of NMR, the algorithm is applicable to any design of quantum computer based on Ising couplings

MIC varies according to the oil used, the major compounds, and the physiology of the bacterium under study. In the present study, the essential oils of the plants Thymus vulgaris (time, Cymbopogon citratus (lemongrass and Laurus nobilis (bay were chemically quantified, and the MIC was determined on the bacteria Staphylococcus aureus ATCC 25923, Escherichia coli ATCC 25922, Listeria monocytogenes ATCC 19117, Salmonella enterica Enteritidis S64, and Pseudomonas aeruginosa ATCC 27853. The essential oil of C. citratus demonstrated bacterial activity at all concentrations tested and against all of the bacteria tested. The majority of essential oil compounds were geranial and neral. The major constituent of T. vulgaris was 1.8-cineol and of L. nobilis was linalool, which presented lower antibacterial activity, followed by 1.8-cineol. The Gram-negative bacteria demonstrated higher resistance to the use of the essential oils tested in this study. E. coli was the least sensitive and was inhibited only by the oils of C. citratus and L. nobilis.Diversos óleos essenciais de plantas condimentares e medicinais possuem atividade antimicrobiana comprovada, sendo de grande interesse para a indústria de alimentos.

Summers, Sioni Paris; Sanders, P.

2017-01-01

Firmware for FPGA trigger applications at the CMS experiment is conventionally written using hardware description languages such as Verilog and VHDL. MaxCompiler is an alternative, Java based, tool for developing FPGA applications which uses a higher level of abstraction from the hardware than a hardware description language. An implementation of the jet and energy sum algorithms for the CMS Level-1 calorimeter trigger has been written using MaxCompiler to benchmark against the VHDL implementation in terms of accuracy, latency, resource usage, and code size. A Kalman Filter track fitting algorithm has been developed using MaxCompiler for a proposed CMS Level-1 track trigger for the High-Luminosity LHC upgrade. The design achieves a low resource usage, and has a latency of 187.5 ns per iteration.

Compiling models into real-time systems

International Nuclear Information System (INIS)

Dormoy, J.L.; Cherriaux, F.; Ancelin, J.

1992-08-01

This paper presents an architecture for building real-time systems from models, and model-compiling techniques. This has been applied for building a real-time model-based monitoring system for nuclear plants, called KSE, which is currently being used in two plants in France. We describe how we used various artificial intelligence techniques for building it: a model-based approach, a logical model of its operation, a declarative implementation of these models, and original knowledge-compiling techniques for automatically generating the real-time expert system from those models. Some of those techniques have just been borrowed from the literature, but we had to modify or invent other techniques which simply did not exist. We also discuss two important problems, which are often underestimated in the artificial intelligence literature: size, and errors. Our architecture, which could be used in other applications, combines the advantages of the model-based approach with the efficiency requirements of real-time applications, while in general model-based approaches present serious drawbacks on this point

Saldana A, H.

1978-01-01

We deal with high level programming language of a Regular Expressions Compiler (REC). The first chapter is an introduction in which the history of the REC development and the problems related to its numerous applicatons are described. The syntactic and sematic rules as well as the language features are discussed just after the introduction. Concerning the applicatons as examples, an adaptation is given in order to solve numerical problems and another for the data manipulation. The last chapter is an exposition of ideas and techniques about the compiler construction. Examples of the adaptation to numerical problems show the applications to education, vector analysis, quantum mechanics, physics, mathematics and other sciences. The rudiments of an operating system for a minicomputer are the examples of the adaptation to symbolic data manipulaton. REC is a programming language that could be applied to solve problems in almost any human activity. Handling of computer graphics, control equipment, research on languages, microprocessors and general research are some of the fields in which this programming language can be applied and developed.

The National Assessment of Shoreline Change:A GIS Compilation of Vector Shorelines and Associated Shoreline Change Data for the Sandy Shorelines of the California Coast

Science.gov (United States)

Hapke, Cheryl J.; Reid, David

2006-01-01

Introduction The Coastal and Marine Geology Program of the U.S. Geological Survey has generated a comprehensive data clearinghouse of digital vector shorelines and shoreline change rates for the sandy shoreline along the California open coast. These data, which are presented herein, were compiled as part of the U.S. Geological Survey's National Assessment of Shoreline Change Project. Beach erosion is a chronic problem along many open-ocean shores of the United States. As coastal populations continue to grow and community infrastructures are threatened by erosion, there is increased demand for accurate information including rates and trends of shoreline migration. There is also a critical need for shoreline change data that is consistent from one coastal region to another. One purpose of this work is to develop standard, repeatable methods for mapping and analyzing shoreline movement so that periodic, systematic, and internally consistent updates of shorelines and shoreline change rates can be made at a National Scale. This data compilation for open-ocean, sandy shorelines of the California coast is one in a series that already includes the Gulf of Mexico and the Southeast Atlantic Coast (Morton et al., 2004; Morton et al., 2005) and will eventually cover Washington, Oregon, and parts of Hawaii and Alaska. Short- and long-term shoreline change evaluations are determined by comparing the positions of three historical shorelines digitized from maps, with a modern shoreline derived from LIDAR (light detection and ranging) topographic surveys. Historical shorelines generally represent the following time-periods: 1850s-1880s, 1920s-1930s, and late 1940s-1970s. The most recent shoreline is from data collected between 1997 and 2002. Long-term rates of change are calculated by linear regression using all four shorelines. Short-term rates of change are end-point rate calculations using the two most recent shorelines. Please refer to our full report on shoreline change of the

2005-03-01

Full Text Available Abstract Background The Marine Genomics project is a functional genomics initiative developed to provide a pipeline for the curation of Expressed Sequence Tags (ESTs and gene expression microarray data for marine organisms. It provides a unique clearing-house for marine specific EST and microarray data and is currently available at http://www.marinegenomics.org. Description The Marine Genomics pipeline automates the processing, maintenance, storage and analysis of EST and microarray data for an increasing number of marine species. It currently contains 19 species databases (over 46,000 EST sequences that are maintained by registered users from local and remote locations in Europe and South America in addition to the USA. A collection of analysis tools are implemented. These include a pipeline upload tool for EST FASTA file, sequence trace file and microarray data, an annotative text search, automated sequence trimming, sequence quality control (QA/QC editing, sequence BLAST capabilities and a tool for interactive submission to GenBank. Another feature of this resource is the integration with a scientific computing analysis environment implemented by MATLAB. Conclusion The conglomeration of multiple marine organisms with integrated analysis tools enables users to focus on the comprehensive descriptions of transcriptomic responses to typical marine stresses. This cross species data comparison and integration enables users to contain their research within a marine-oriented data management and analysis environment.

European Clearinghouse. Incidents related to reactivity management. Contributing factors, failure modes and corrective actions

International Nuclear Information System (INIS)

Bruynooghe, Christiane; Noel, Marc

2009-01-01

This work is part of the European Clearinghouse on Nuclear Power Plant Operational Experience Feedback (NPP-OEF) activity carried out at the Joint Research Centre/Institute for Energy (JRC/IE) with the participation of nine EU Regulatory Authorities. It investigates the 1999 Shika-1 criticality event together with other shortcomings in reactivity management reported to the IAE4 Incident Reporting System in the period 1981-2008. The aim of the work was to identify reactivity control failure modes, reactor status and corrective actions. Initiating factors and associated root causes were also analysed. Five of the 7 factors identified for all events were present in the 1999 Shika-1 event where criticality has been unexpectedly reached and maintained during 15 minutes. Most of the events resulted in changes in procedures, material or staff and management training. The analysis carried out put in evidence that in several instances appropriate communication based on operational experience feedback would have prevented incident to occur. This paper also summarises the action taken at power plants and by the regulatory bodies in different countries to avoid repetition of similar events. It identifies insights that might be useful to reduce the likelihood of operational events caused by shortcomings in reactivity management. (orig.)

ZettaBricks: A Language Compiler and Runtime System for Anyscale Computing

Energy Technology Data Exchange (ETDEWEB)

Amarasinghe, Saman [Massachusetts Inst. of Technology (MIT), Cambridge, MA (United States)

2015-03-27

This grant supported the ZettaBricks and OpenTuner projects. ZettaBricks is a new implicitly parallel language and compiler where defining multiple implementations of multiple algorithms to solve a problem is the natural way of programming. ZettaBricks makes algorithmic choice a first class construct of the language. Choices are provided in a way that also allows our compiler to tune at a finer granularity. The ZettaBricks compiler autotunes programs by making both fine-grained as well as algorithmic choices. Choices also include different automatic parallelization techniques, data distributions, algorithmic parameters, transformations, and blocking. Additionally, ZettaBricks introduces novel techniques to autotune algorithms for different convergence criteria. When choosing between various direct and iterative methods, the ZettaBricks compiler is able to tune a program in such a way that delivers near-optimal efficiency for any desired level of accuracy. The compiler has the flexibility of utilizing different convergence criteria for the various components within a single algorithm, providing the user with accuracy choice alongside algorithmic choice. OpenTuner is a generalization of the experience gained in building an autotuner for ZettaBricks. OpenTuner is a new open source framework for building domain-specific multi-objective program autotuners. OpenTuner supports fully-customizable configuration representations, an extensible technique representation to allow for domain-specific techniques, and an easy to use interface for communicating with the program to be autotuned. A key capability inside OpenTuner is the use of ensembles of disparate search techniques simultaneously; techniques that perform well will dynamically be allocated a larger proportion of tests.

Full Text Available In the process of ocean development, the technology for maritime communication system is a hot research field, of which information security is vital for the normal operation of the whole system, and that is also one of the difficulties in the research of maritime communication system. In this paper, a kind of maritime communication cryptographic SOC(system on chip is introduced, and its compiler framework is put forward through analysis of working mode and problems faced by compiler front end. Then, a loop unrolling factor calculating algorithm based on queue theory, named UFBOQ (unrolling factor based on queue, is proposed to make parallel optimization in the compiler frontend with consideration of the instruction memory capacity limit. Finally, the scalar replacement method is used to optimize unrolled code to solve the memory access latency on the parallel computing efficiency, for continuous data storage characteristics of cryptographic algorithm. The UFBOQ algorithm and scalar replacement prove effective and appropriate, of which the effect achieves the linear speedup.

Full Text Available This paper demonstrates that significant improvements to automatic parallelization technology require that existing systems be extended in two ways: (1 they must combine high‐quality compile‐time analysis with low‐cost run‐time testing; and (2 they must take control flow into account during analysis. We support this claim with the results of an experiment that measures the safety of parallelization at run time for loops left unparallelized by the Stanford SUIF compiler’s automatic parallelization system. We present results of measurements on programs from two benchmark suites – SPECFP95 and NAS sample benchmarks – which identify inherently parallel loops in these programs that are missed by the compiler. We characterize remaining parallelization opportunities, and find that most of the loops require run‐time testing, analysis of control flow, or some combination of the two. We present a new compile‐time analysis technique that can be used to parallelize most of these remaining loops. This technique is designed to not only improve the results of compile‐time parallelization, but also to produce low‐cost, directed run‐time tests that allow the system to defer binding of parallelization until run‐time when safety cannot be proven statically. We call this approach predicated array data‐flow analysis. We augment array data‐flow analysis, which the compiler uses to identify independent and privatizable arrays, by associating predicates with array data‐flow values. Predicated array data‐flow analysis allows the compiler to derive “optimistic” data‐flow values guarded by predicates; these predicates can be used to derive a run‐time test guaranteeing the safety of parallelization.

Mode automata and their compilation into fault trees

International Nuclear Information System (INIS)

Rauzy, Antoine

2002-01-01

In this article, we advocate the use of mode automata as a high level representation language for reliability studies. Mode automata are states/transitions based representations with the additional notion of flow. They can be seen as a generalization of both finite capacity Petri nets and block diagrams. They can be assembled into hierarchies by means of composition operations. The contribution of this article is twofold. First, we introduce mode automata and we discuss their relationship with other formalisms. Second, we propose an algorithm to compile mode automata into Boolean equations (fault trees). Such a compilation is of interest for two reasons. First, assessment tools for Boolean models are much more efficient than those for states/transitions models. Second, the automated generation of fault trees from higher level representations makes easier their maintenance through the life cycle of systems under study

Compiler Technology for Parallel Scientific Computation

Directory of Open Access Journals (Sweden)

Can Özturan

1994-01-01

Full Text Available There is a need for compiler technology that, given the source program, will generate efficient parallel codes for different architectures with minimal user involvement. Parallel computation is becoming indispensable in solving large-scale problems in science and engineering. Yet, the use of parallel computation is limited by the high costs of developing the needed software. To overcome this difficulty we advocate a comprehensive approach to the development of scalable architecture-independent software for scientific computation based on our experience with equational programming language (EPL. Our approach is based on a program decomposition, parallel code synthesis, and run-time support for parallel scientific computation. The program decomposition is guided by the source program annotations provided by the user. The synthesis of parallel code is based on configurations that describe the overall computation as a set of interacting components. Run-time support is provided by the compiler-generated code that redistributes computation and data during object program execution. The generated parallel code is optimized using techniques of data alignment, operator placement, wavefront determination, and memory optimization. In this article we discuss annotations, configurations, parallel code generation, and run-time support suitable for parallel programs written in the functional parallel programming language EPL and in Fortran.

ABSTRACT: On the basis of sample analysis of a Czech adjective, a definition based on the data drawn from the Czech National Corpus (cf. Čermák and Schmiedtová 2003 is gradually compiled and finally offered, pointing at the drawbacks of definitions found in traditional dictionaries. Steps undertaken here are then generalized and used, in an ordered sequence (similar to a work-flow ordering, as topics, briefly discussed in the second part to which lexicographers of monolingual dictionaries should pay attention. These are supplemented by additional remarks and caveats useful in the compilation of a dictionary. Thus, a brief survey of some of the major steps of dictionary compilation is presented here, supplemented by the original Czech data, analyzed in their raw, though semiotically classified form.

A Performance Tuning Methodology with Compiler Support

Directory of Open Access Journals (Sweden)

Oscar Hernandez

2008-01-01

Full Text Available We have developed an environment, based upon robust, existing, open source software, for tuning applications written using MPI, OpenMP or both. The goal of this effort, which integrates the OpenUH compiler and several popular performance tools, is to increase user productivity by providing an automated, scalable performance measurement and optimization system. In this paper we describe our environment, show how these complementary tools can work together, and illustrate the synergies possible by exploiting their individual strengths and combined interactions. We also present a methodology for performance tuning that is enabled by this environment. One of the benefits of using compiler technology in this context is that it can direct the performance measurements to capture events at different levels of granularity and help assess their importance, which we have shown to significantly reduce the measurement overheads. The compiler can also help when attempting to understand the performance results: it can supply information on how a code was translated and whether optimizations were applied. Our methodology combines two performance views of the application to find bottlenecks. The first is a high level view that focuses on OpenMP/MPI performance problems such as synchronization cost and load imbalances; the second is a low level view that focuses on hardware counter analysis with derived metrics that assess the efficiency of the code. Our experiments have shown that our approach can significantly reduce overheads for both profiling and tracing to acceptable levels and limit the number of times the application needs to be run with selected hardware counters. In this paper, we demonstrate the workings of this methodology by illustrating its use with selected NAS Parallel Benchmarks and a cloud resolving code.

HAL/S-FC and HAL/S-360 compiler system program description

Science.gov (United States)

1976-01-01

The compiler is a large multi-phase design and can be broken into four phases: Phase 1 inputs the source language and does a syntactic and semantic analysis generating the source listing, a file of instructions in an internal format (HALMAT) and a collection of tables to be used in subsequent phases. Phase 1.5 massages the code produced by Phase 1, performing machine independent optimization. Phase 2 inputs the HALMAT produced by Phase 1 and outputs machine language object modules in a form suitable for the OS-360 or FCOS linkage editor. Phase 3 produces the SDF tables. The four phases described are written in XPL, a language specifically designed for compiler implementation. In addition to the compiler, there is a large library containing all the routines that can be explicitly called by the source language programmer plus a large collection of routines for implementing various facilities of the language.

Scientific Programming with High Performance Fortran: A Case Study Using the xHPF Compiler

Directory of Open Access Journals (Sweden)

Eric De Sturler

1997-01-01

Full Text Available Recently, the first commercial High Performance Fortran (HPF subset compilers have appeared. This article reports on our experiences with the xHPF compiler of Applied Parallel Research, version 1.2, for the Intel Paragon. At this stage, we do not expect very High Performance from our HPF programs, even though performance will eventually be of paramount importance for the acceptance of HPF. Instead, our primary objective is to study how to convert large Fortran 77 (F77 programs to HPF such that the compiler generates reasonably efficient parallel code. We report on a case study that identifies several problems when parallelizing code with HPF; most of these problems affect current HPF compiler technology in general, although some are specific for the xHPF compiler. We discuss our solutions from the perspective of the scientific programmer, and presenttiming results on the Intel Paragon. The case study comprises three programs of different complexity with respect to parallelization. We use the dense matrix-matrix product to show that the distribution of arrays and the order of nested loops significantly influence the performance of the parallel program. We use Gaussian elimination with partial pivoting to study the parallelization strategy of the compiler. There are various ways to structure this algorithm for a particular data distribution. This example shows how much effort may be demanded from the programmer to support the compiler in generating an efficient parallel implementation. Finally, we use a small application to show that the more complicated structure of a larger program may introduce problems for the parallelization, even though all subroutines of the application are easy to parallelize by themselves. The application consists of a finite volume discretization on a structured grid and a nested iterative solver. Our case study shows that it is possible to obtain reasonably efficient parallel programs with xHPF, although the compiler

Compiler-Enforced Cache Coherence Using a Functional Language

Directory of Open Access Journals (Sweden)

Rich Wolski

1996-01-01

Full Text Available The cost of hardware cache coherence, both in terms of execution delay and operational cost, is substantial for scalable systems. Fortunately, compiler-generated cache management can reduce program serialization due to cache contention; increase execution performance; and reduce the cost of parallel systems by eliminating the need for more expensive hardware support. In this article, we use the Sisal functional language system as a vehicle to implement and investigate automatic, compiler-based cache management. We describe our implementation of Sisal for the IBM Power/4. The Power/4, briefly available as a product, represents an early attempt to build a shared memory machine that relies strictly on the language system for cache coherence. We discuss the issues associated with deterministic execution and program correctness on a system without hardware coherence, and demonstrate how Sisal (as a functional language is able to address those issues.

Pollution prevention incentives and disincentives created by the Clean Air Act

International Nuclear Information System (INIS)

Webb, C.F.; Wolffe, G.S.

1998-01-01

Environmental laws and regulations have not always been implemented in a manner that allows for the consideration of pollution prevention (P2) alternatives as a means of achieving progress toward air quality goals. Recently, the US Environmental Protection Agency (EPA) has been making strides to reinterpret laws and regulations to be more flexible and encourage P2 projects that do not involve end-of-the-pipe controls. For instance, when conducting control technology evaluations such as best available control technology (BACT) and lowest achievable emission rate (LAER), facilities can and should take into consideration P2 options that accomplish the same emission reduction goals as traditional end-of-the-pipe controls. There are also new emissions trading provisions building on those allowed in the acid rain and offset trading programs that promise to make P2 projects much more cost-effective. Several traditional 'command-and-control' programs of the Clean Air Act (CAA) also promote P2 projects. For instance, emission reductions realized through P2 projects show managers a direct cost savings due to reductions in Title V facility annual emissions fees and possibly a direct cost benefit through sale of emission credits. Furthermore, the CAA encourages P2 indirectly through the detail understanding of processes gained from emissions inventories and risk management plans (RMPs). However, many CAA prescriptive programs create disincentives for industry to select P2 alternatives. 30 refs

Workflow with pitfalls to derive a regional airborne magnetic compilation

Science.gov (United States)

Brönner, Marco; Baykiev, Eldar; Ebbing, Jörg

2017-04-01

Today, large scale magnetic maps are usually a patchwork of different airborne surveys from different size, different resolution and different years. Airborne magnetic acquisition is a fast and economic method to map and gain geological and tectonic information for large areas, onshore and offshore. Depending on the aim of a survey, acquisition parameters like altitude and profile distance are usually adjusted to match the purpose of investigation. The subsequent data processing commonly follows a standardized workflow comprising core-field subtraction and line leveling to yield a coherent crustal field magnetic grid for a survey area. The resulting data makes it possible to correlate with geological and tectonic features in the subsurface, which is of importance for e.g. oil and mineral exploration. Crustal scale magnetic interpretation and modeling demand regional compilation of magnetic data and the merger of adjacent magnetic surveys. These studies not only focus on shallower sources, reflected by short to intermediate magnetic wavelength anomalies, but also have a particular interest in the long wavelength deriving from deep seated sources. However, whilst the workflow to produce such a merger is supported by quite a few powerful routines, the resulting compilation contains several pitfalls and limitations, which were discussed before, but still are very little recognized. The maximum wavelength that can be resolved of each individual survey is directly related to the survey size and consequently a merger will contribute erroneous long-wavelength components in the magnetic data compilation. To minimize this problem and to homogenous the longer wavelengths, a first order approach is the combination of airborne and satellite magnetic data commonly combined with the compilation from airborne data, which is sufficient only under particular preconditions. A more advanced approach considers the gap in frequencies between airborne and satellite data, which motivated

Digital Bedrock Compilation: A Geodatabase Covering Forest Service Lands in California

Science.gov (United States)

Elder, D.; de La Fuente, J. A.; Reichert, M.

2010-12-01

This digital database contains bedrock geologic mapping for Forest Service lands within California. This compilation began in 2004 and the first version was completed in 2005. Second publication of this geodatabase was completed in 2010 and filled major gaps in the southern Sierra Nevada and Modoc/Medicine Lake/Warner Mountains areas. This digital map database was compiled from previously published and unpublished geologic mapping, with source mapping and review from California Geological Survey, the U.S. Geological Survey and others. Much of the source data was itself compilation mapping. This geodatabase is huge, containing ~107,000 polygons and ~ 280,000 arcs. Mapping was compiled from more than one thousand individual sources and covers over 41,000,000 acres (~166,000 km2). It was compiled from source maps at various scales - from ~ 1:4,000 to 1:250,000 and represents the best available geologic mapping at largest scale possible. An estimated 70-80% of the source information was digitized from geologic mapping at 1:62,500 scale or better. Forest Service ACT2 Enterprise Team compiled the bedrock mapping and developed a geodatabase to store this information. This geodatabase supports feature classes for polygons (e.g, map units), lines (e.g., contacts, boundaries, faults and structural lines) and points (e.g., orientation data, structural symbology). Lookup tables provide detailed information for feature class items. Lookup/type tables contain legal values and hierarchical groupings for geologic ages and lithologies. Type tables link coded values with descriptions for line and point attributes, such as line type, line location and point type. This digital mapping is at the core of many quantitative analyses and derivative map products. Queries of the database are used to produce maps and to quantify rock types of interest. These include the following: (1) ultramafic rocks - where hazards from naturally occurring asbestos are high, (2) granitic rocks - increased

Nuclear fuel cycle risk assessment: survey and computer compilation of risk-related literature

International Nuclear Information System (INIS)

Yates, K.R.; Schreiber, A.M.; Rudolph, A.W.

1982-10-01

The US Nuclear Regulatory Commission has initiated the Fuel Cycle Risk Assessment Program to provide risk assessment methods for assistance in the regulatory process for nuclear fuel cycle facilities other than reactors. Both the once-through cycle and plutonium recycle are being considered. A previous report generated by this program defines and describes fuel cycle facilities, or elements, considered in the program. This report, the second from the program, describes the survey and computer compilation of fuel cycle risk-related literature. Sources of available information on the design, safety, and risk associated with the defined set of fuel cycle elements were searched and documents obtained were catalogued and characterized with respect to fuel cycle elements and specific risk/safety information. Both US and foreign surveys were conducted. Battelle's computer-based BASIS information management system was used to facilitate the establishment of the literature compilation. A complete listing of the literature compilation and several useful indexes are included. Future updates of the literature compilation will be published periodically. 760 annotated citations are included

As the cost of data movement increasingly dominates performance, developers of finite-volume and finite-difference solutions for partial differential equations (PDEs) are exploring novel higher-order stencils that increase numerical accuracy and computational intensity. This paper describes a new compiler reordering transformation applied to stencil operators that performs partial sums in buffers, and reuses the partial sums in computing multiple results. This optimization has multiple effect son improving stencil performance that are particularly important to higher-order stencils: exploits data reuse, reduces floating-point operations, and exposes efficient SIMD parallelism to backend compilers. We study the benefit of this optimization in the context of Geometric Multigrid (GMG), a widely used method to solvePDEs, using four different Jacobi smoothers built from 7-, 13-, 27-and 125-point stencils. We quantify performance, speedup, andnumerical accuracy, and use the Roofline model to qualify our results. Ultimately, we obtain over 4× speedup on the smoothers themselves and up to a 3× speedup on the multigrid solver. Finally, we demonstrate that high-order multigrid solvers have the potential of reducing total data movement and energy by several orders of magnitude.

Expert Programmer versus Parallelizing Compiler: A Comparative Study of Two Approaches for Distributed Shared Memory

Directory of Open Access Journals (Sweden)

M. F. P. O'Boyle

1996-01-01

Full Text Available This article critically examines current parallel programming practice and optimizing compiler development. The general strategies employed by compiler and programmer to optimize a Fortran program are described, and then illustrated for a specific case by applying them to a well-known scientific program, TRED2, using the KSR-1 as the target architecture. Extensive measurement is applied to the resulting versions of the program, which are compared with a version produced by a commercial optimizing compiler, KAP. The compiler strategy significantly outperforms KAP and does not fall far short of the performance achieved by the programmer. Following the experimental section each approach is critiqued by the other. Perceived flaws, advantages, and common ground are outlined, with an eye to improving both schemes.

Full Text Available We propose a fast data relay (FDR mechanism to enhance existing CGRA (coarse-grained reconfigurable architecture. FDR can not only provide multicycle data transmission in concurrent with computations but also convert resource-demanding inter-processing-element global data accesses into local data accesses to avoid communication congestion. We also propose the supporting compiler techniques that can efficiently utilize the FDR feature to achieve higher performance for a variety of applications. Our results on FDR-based CGRA are compared with two other works in this field: ADRES and RCP. Experimental results for various multimedia applications show that FDR combined with the new compiler deliver up to 29% and 21% higher performance than ADRES and RCP, respectively.

2007-02-15

The main objective with this report, the Construction Experience Compilation Report (CECR), is to compile experiences from the underground works carried out at Forsmark, primarily construction experiences from the tunnelling of the two cooling water tunnels of the Forsmark nuclear power units 1, 2 and 3, and from the underground excavations of the undersea repository for low and intermediate reactor waste, SFR. In addition, a brief account is given of the operational experience of the SFR on primarily rock support solutions. The authors of this report have separately participated throughout the entire construction periods of the Forsmark units and the SFR in the capacity of engineering geologists performing geotechnical mapping of the underground excavations and acted as advisors on tunnel support; Anders Carlsson participated in the construction works of the cooling water tunnels and the open cut excavations for Forsmark 1, 2 and 3 (geotechnical mapping) and the Forsmark 3 tunnel (advise on tunnel support). Rolf Christiansson participated in the underground works for the SFR (geotechnical mapping, principal investigator for various measurements and advise on tunnel support and grouting). The report is to a great extent based on earlier published material as presented in the list of references. But it stands to reason that, during the course of the work with this report, unpublished notes, diaries, drawings, photos and personal recollections of the two authors have been utilised in order to obtain such a complete compilation of the construction experiences as possible.

2014-06-01

Objectives: The aim of this study was to describe and highlight the characteristics of NS in order to compile a preliminary checklist for accurate diagnosis and intervention. Method: An explorative, applied mixed method, multiple case study research design was followed. Purposive sampling was used to select four participants. A comprehensive assessment battery was compiled for data collection. Results: The results revealed a distinct pattern of core stuttering behaviours in NS, although discrepancies existed regarding stuttering severity and frequency. It was also found that DS and NS can co-occur. The case history and the core stuttering pattern are important considerations during differential diagnosis, as these are the only consistent characteristics in people with NS. Conclusion: It is unlikely that all the symptoms of NS are present in an individual. The researchers scrutinised the findings of this study and the findings of previous literature to compile a potentially workable checklist.

The rapidly growing wealth of nuclear data becomes less and less easily accessible to the astrophysics community. Mastering this volume of information and making it available in an accurate and usable form for incorporation into stellar evolution or nucleosynthesis models become urgent goals of prime necessity. we report on the results of the European network NACRE (Nuclear Astrophysics Compilation of REaction rates). The principal motivation for the setting-up of the NACRE network has been the necessity of building up a well-documented and detailed compilation of rates for charged-particle induced reactions on stable targets up to Si and on unstable nuclei of special significance in astrophysics. This work is meant to supersede the only existing compilation of reaction rates issued by Fowler and collaborators. The cross section data and/or resonance parameters for a total of 86 charged-particle induced reactions are given and the corresponding reaction rates are calculated and given in tabular form. When cross section data are not available in the whole needed range of energies, the theoretical predictions obtained in the framework of the Hauser-Feshbach model is used. Uncertainties are analyzed and realistic upper and lower bounds of the rates are determined. Reverse reaction rates and analytical approximations of the adopted rates are also provided. (authors)

Full Text Available O estudo consistiu em avaliar a sobrevivência e a eficiência das bactérias diazotróficas Herbaspirillum seropedicae, Burkholderia sp. e Azospirillum brasilense, inoculadas em dois tipos de turfas. A sobrevivência das bactérias foi determinada pelo método do NúmeroMais Provável (NMP, durante o armazenamento de até seis meses. A eficiência foi avaliada pela contribuição destas bactérias nos parâmetros agronômicos de acúmulo de massa seca e N-total dos grãos nas variedades de arroz IR42 e IAC4440. O experimento foi conduzido emvasos com solo, em delineamento inteiramente casualizado com três repetições, em arranjo fatorial 2 x 4. Os dados obtidos mostraram que o inoculante contendo a estirpe de Burkholderia sp. manteve o número de células viáveis em torno de 108 cel. g-1 de turfa no período testado, enquanto nos demais inoculantes este número ficou em torno de 106. Os ensaios de inoculação não mostraram diferenças significativas quanto à origem das turfas usadas como veículo sobre os parâmetros agronômicos e sobrevivência das bactérias. O tratamento que continha H. seropedicae manteve o acúmulo de massa seca e N-total dos grãos estatisticamente igual ao tratamento que recebeu 40 kg N ha-1, embora tenham sido observados aumentos de 13 e 19,4% nestes parâmetros na variedade IAC4440. Os resultados mostraram-se promissores quanto à utilização da prática de inoculação na cultura do arroz.

The wide field of utilization of FORTH leads us to develop an interpreter. It has been implemented on a MC 68000 microprocessor based computer, with ASTERIX, a UNIX-like operating system (real time system written by C.E.A.). This work has been done in two different versions: - The first one, fully written in C language, assures a good portability on a wide variety of microprocessors. But the performance estimations show off excessive execution times, and lead to a new optimized version. - This new version is characterized by the compilation of the most frequently used words of the FORTH basis. This allows us to get an interpreter with good performances and an execution speed close to the resulting one of the C compiler. (author) [fr

Brown-Vialetto-Van Laere Syndrome (BVVLS), a rare neurological disorder characterized by bulbar palsies and sensorineural deafness, is mainly associated with defective riboflavin transporters encoded by the SLC52A2 and SLC52A3 genes. Here we present a 16-year-old BVVLS patient belonging to a five generation consanguineous family from Indian ethnicity with two homozygous missense mutations viz., c.421C>A [p.P141T] in SLC52A2 and c.62A>G [p.N21S] in SLC52A3. Functional characterization based on 3 H-riboflavin uptake assay and live-cell confocal imaging revealed that the effect of mutation c.421C>A [p.P141T] identified in SLC52A2 had a slight reduction in riboflavin uptake; on the other hand, the c.62A>G [p.N21S] identified in SLC52A3 showed a drastic reduction in riboflavin uptake, which appeared to be due to impaired trafficking and membrane targeting of the hRFVT-3 protein. This is the first report presenting mutations in both riboflavin transporters hRFVT-2 and hRFVT-3 in the same BVVLS patient. Also, c.62A>G [p.N21S] in SLC52A3 appears to contribute more to the disease phenotype in this patient than c.421C>A [p.P141T] in SLC52A2. Copyright © 2016 Elsevier B.V. All rights reserved.

The overall goal of this study is to compile an open-source OPEC[1] Word List (OWL that is available for lexicographic research and vocabulary learning related to English language learning for the purpose of oil marketing and oil industries. To achieve this goal, an OPEC Monthly Reports Corpus (OMRC comprising of 1,004,542 words was compiled. The OMRC consists of 40 OPEC monthly reports released between 2003 and 2015. Consideration was given to both range and frequency criteria when compiling the OWL which consists of 255 word types. Along with this basic goal, this study aims to investigate the coverage of the most well-recognised word lists, the General Service List of English Words (GSL (West ,1953  and  the Academic Word List (AWL (Coxhead, 2000 in the OMRC corpus. The 255 word types included in the OWL are not overlapping with either the AWL or the GSL. Results suggest the necessity of making this discipline-specific word list for ESL students of oil marketing industries. The availability of the OWL has significant pedagogical contributions to curriculum design, learning activities and the overall process of vocabulary learning in the context of teaching English for specific purposes (ESP.

Shear-wave velocity compilation for Northridge strong-motion recording sites

Science.gov (United States)

Borcherdt, Roger D.; Fumal, Thomas E.

2002-01-01

Borehole and other geotechnical information collected at the strong-motion recording sites of the Northridge earthquake of January 17, 1994 provide an important new basis for the characterization of local site conditions. These geotechnical data, when combined with analysis of strong-motion recordings, provide an empirical basis to evaluate site coefficients used in current versions of US building codes. Shear-wave-velocity estimates to a depth of 30 meters are derived for 176 strong-motion recording sites. The estimates are based on borehole shear-velocity logs, physical property logs, correlations with physical properties and digital geologic maps. Surface-wave velocity measurements and standard penetration data are compiled as additional constraints. These data as compiled from a variety of databases are presented via GIS maps and corresponding tables to facilitate use by other investigators.

The RHNumtS compilation: Features and bioinformatics approaches to locate and quantify Human NumtS

Directory of Open Access Journals (Sweden)

Saccone Cecilia

2008-06-01

Full Text Available Abstract Background To a greater or lesser extent, eukaryotic nuclear genomes contain fragments of their mitochondrial genome counterpart, deriving from the random insertion of damaged mtDNA fragments. NumtS (Nuclear mt Sequences are not equally abundant in all species, and are redundant and polymorphic in terms of copy number. In population and clinical genetics, it is important to have a complete overview of NumtS quantity and location. Searching PubMed for NumtS or Mitochondrial pseudo-genes yields hundreds of papers reporting Human NumtS compilations produced by in silico or wet-lab approaches. A comparison of published compilations clearly shows significant discrepancies among data, due both to unwise application of Bioinformatics methods and to a not yet correctly assembled nuclear genome. To optimize quantification and location of NumtS, we produced a consensus compilation of Human NumtS by applying various bioinformatics approaches. Results Location and quantification of NumtS may be achieved by applying database similarity searching methods: we have applied various methods such as Blastn, MegaBlast and BLAT, changing both parameters and database; the results were compared, further analysed and checked against the already published compilations, thus producing the Reference Human Numt Sequences (RHNumtS compilation. The resulting NumtS total 190. Conclusion The RHNumtS compilation represents a highly reliable reference basis, which may allow designing a lab protocol to test the actual existence of each NumtS. Here we report preliminary results based on PCR amplification and sequencing on 41 NumtS selected from RHNumtS among those with lower score. In parallel, we are currently designing the RHNumtS database structure for implementation in the HmtDB resource. In the future, the same database will host NumtS compilations from other organisms, but these will be generated only when the nuclear genome of a specific organism has reached a high

Data compilation of angular distributions of sputtered atoms

International Nuclear Information System (INIS)

Yamamura, Yasunori; Takiguchi, Takashi; Tawara, Hiro.

1990-01-01

Sputtering on a surface is generally caused by the collision cascade developed near the surface. The process is in principle the same as that causing radiation damage in the bulk of solids. Sputtering has long been regarded as an undesirable dirty effect which destroys the cathodes and grids in gas discharge tubes or ion sources and contaminates plasma and the surrounding walls. However, sputtering is used today for many applications such as sputter ion sources, mass spectrometers and the deposition of thin films. Plasma contamination and the surface erosion of first walls due to sputtering are still the major problems in fusion research. The angular distribution of the particles sputtered from solid surfaces can possibly provide the detailed information on the collision cascade in the interior of targets. This report presents a compilation of the angular distribution of sputtered atoms at normal incidence and oblique incidence in the various combinations of incident ions and target atoms. The angular distribution of sputtered atoms from monatomic solids at normal incidence and oblique incidence, and the compilation of the data on the angular distribution of sputtered atoms are reported.

A new compiler for the GANIL Data Acquisition description

International Nuclear Information System (INIS)

Saillant, F.; Raine, B.

1997-01-01

An important feature of the GANIL Data Acquisition System is the description of the experiments by means of a language developed at GANIL. The philosophy is to attribute to each element (parameters, spectra, etc) an operational name which will be used at any level of the system. This language references a library of modules to free the user from the technical details of the hardware. This compiler has been recently entirely re-developed using technologies as the object-oriented language (C++) and object-oriented software development method and tool. This enables us to provide a new functionality or to support a new electronic module within a very short delay and without any deep modification of the application. A new Dynamic Library of Modules has been also developed. Its complete description is available on the GANIL WEB site http://ganinfo.in2p3.fr/acquisition/homepage.html. This new compiler brings a lot of new functionalities, among which the most important is the notion of 'register' whatever the module standard is. All the registers described in the module provider's documentation can now be accessed by their names. Another important new feature is the notion of 'function' that can be executed on a module. Also a set of new instructions has been implemented to execute commands on CAMAC crates. Another possibility of this new compiler is to enable the description of specific interfaces with GANIL Data Acquisition System. This has been used to describe the coupling of the CHIMERA Data Acquisition System with the INDRA one through a shared memory in the VME crate. (authors)

A quantum CISC compiler and scalable assembler for quantum computing on large systems

Energy Technology Data Exchange (ETDEWEB)

Schulte-Herbrueggen, Thomas; Spoerl, Andreas; Glaser, Steffen [Dept. Chemistry, Technical University of Munich (TUM), 85747 Garching (Germany)

2008-07-01

Using the cutting edge high-speed parallel cluster HLRB-II (with a total LINPACK performance of 63.3 TFlops/s) we present a quantum CISC compiler into time-optimised or decoherence-protected complex instruction sets. They comprise effective multi-qubit interactions with up to 10 qubits. We show how to assemble these medium-sized CISC-modules in a scalable way for quantum computation on large systems. Extending the toolbox of universal gates by optimised complex multi-qubit instruction sets paves the way to fight decoherence in realistic Markovian and non-Markovian settings. The advantage of quantum CISC compilation over standard RISC compilations into one- and two-qubit universal gates is demonstrated inter alia for the quantum Fourier transform (QFT) and for multiply-controlled NOT gates. The speed-up is up to factor of six thus giving significantly better performance under decoherence. - Implications for upper limits to time complexities are also derived.

For next-generation super computing systems, research was made on parallel and distributed compiler technology for enhancing an effective performance, and concerned software and architectures for enhancing a performance in coordination with compilers. As for parallel compiler technology, the researches of scalable automated parallel compiler technology, parallel tuning tools, and an operating system to use multi-processor resources effectively are pointed out to be important as concrete technical development issues. In addition, by developing these research results to the architecture technology of single-chip multi-processors, the possibility of development and expansion of the PC, WS and HPC (high-performance computer) markets, and creation of new industries is pointed out. Although wide-area distributed computing is being watched as next-generation computing industry, concrete industrial fields using such computing are now not clear, staying in the groping research stage.

The authors assessed the quality of single-case design (SCD) studies that assess the impact of interventions on outcomes for individuals who are deaf or hard-of-hearing (DHH). More specifically, the What Works Clearinghouse (WWC) standards for SCD research were used to assess design quality and the strength of evidence of peer-reviewed studies available in the peer-reviewed, published literature. The analysis yielded four studies that met the WWC standards for design quality, of which two demonstrated moderate to strong evidence for efficacy of the studied intervention. Results of this review are discussed in light of the benefits and the challenges to applying the WWC design standards to research with DHH individuals and other diverse, low-incidence populations. © The Author 2015.

GRESS, FORTRAN Pre-compiler with Differentiation Enhancement

International Nuclear Information System (INIS)

1999-01-01

1 - Description of program or function: The GRESS FORTRAN pre-compiler (SYMG) and run-time library are used to enhance conventional FORTRAN-77 programs with analytic differentiation of arithmetic statements for automatic differentiation in either forward or reverse mode. GRESS 3.0 is functionally equivalent to GRESS 2.1. GRESS 2.1 is an improved and updated version of the previous released GRESS 1.1. Improvements in the implementation of a the CHAIN option have resulted in a 70 to 85% reduction in execution time and up to a 50% reduction in memory required for forward chaining applications. 2 - Method of solution: GRESS uses a pre-compiler to analyze FORTRAN statements and determine the mathematical operations embodied in them. As each arithmetic assignment statement in a program is analyzed, SYMG generates the partial derivatives of the term on the left with respect to each floating-point variable on the right. The result of the pre-compilation step is a new FORTRAN program that can produce derivatives for any REAL (i.e., single or double precision) variable calculated by the model. Consequently, GRESS enhances FORTRAN programs or subprograms by adding the calculation of derivatives along with the original output. Derivatives from a GRESS enhanced model can be used internally (e.g., iteration acceleration) or externally (e.g., sensitivity studies). By calling GRESS run-time routines, derivatives can be propagated through the code via the chain rule (referred to as the CHAIN option) or accumulated to create an adjoint matrix (referred to as the ADGEN option). A third option, GENSUB, makes it possible to process a subset of a program (i.e., a do loop, subroutine, function, a sequence of subroutines, or a whole program) for calculating derivatives of dependent variables with respect to independent variables. A code enhanced with the GENSUB option can use forward mode, reverse mode, or a hybrid of the two modes. 3 - Restrictions on the complexity of the problem: GRESS

IAEA's experience in compiling a generic component reliability data base

International Nuclear Information System (INIS)

Tomic, B.; Lederman, L.

1991-01-01

Reliability data are essential in probabilistic safety assessment, with component reliability parameters being particularly important. Component failure data which is plant specific would be most appropriate but this is rather limited. However, similar components are used in different designs. Generic data, that is all data that is not plant specific to the plant being analyzed but which relates to components more generally, is important. The International Atomic Energy Agency has compiled the Generic Component Reliability Data Base from data available in the open literature. It is part of the IAEA computer code package for fault/event tree analysis. The Data Base contains 1010 different records including most of the components used in probabilistic safety analyses of nuclear power plants. The data base input was quality controlled and data sources noted. The data compilation procedure and problems associated with using generic data are explained. (UK)

Compilation of requests for nuclear data

International Nuclear Information System (INIS)

Weston, L.W.; Larson, D.C.

1993-02-01

This compilation represents the current needs for nuclear data measurements and evaluations as expressed by interested fission and fusion reactor designers, medical users of nuclear data, nuclear data evaluators, CSEWG members and other interested parties. The requests and justifications are reviewed by the Data Request and Status Subcommittee of CSEWG as well as most of the general CSEWG membership. The basic format and computer programs for the Request List were produced by the National Nuclear Data Center (NNDC) at Brookhaven National Laboratory. The NNDC produced the Request List for many years. The Request List is compiled from a computerized data file. Each request has a unique isotope, reaction type, requestor and identifying number. The first two digits of the identifying number are the year in which the request was initiated. Every effort has been made to restrict the notations to those used in common nuclear physics textbooks. Most requests are for individual isotopes as are most ENDF evaluations, however, there are some requests for elemental measurements. Each request gives a priority rating which will be discussed in Section 2, the neutron energy range for which the request is made, the accuracy requested in terms of one standard deviation, and the requested energy resolution in terms of one standard deviation. Also given is the requestor with the comments which were furnished with the request. The addresses and telephone numbers of the requestors are given in Appendix 1. ENDF evaluators who may be contacted concerning evaluations are given in Appendix 2. Experimentalists contemplating making one of the requested measurements are encouraged to contact both the requestor and evaluator who may provide valuable information. This is a working document in that it will change with time. New requests or comments may be submitted to the editors or a regular CSEWG member at any time

Compilation of requests for nuclear data

International Nuclear Information System (INIS)

1983-01-01

The purpose of this compilation is to summarize the current needs of US Nuclear Energy programs and other applied technolgies for nuclear data. It is the result of a biennial review in which the Department of Energy (DOE) and contractors, Department of Defense Laboratories and contractors, and other interested groups have been asked to review and revise their requests for nuclear data. It was felt that the evaluators of cross section data and the users of these evaluations should be involved in the review of the data requests to make this compilation more useful. This request list is ordered by target nucleus (Isotope) and then reaction type (Quantity). Each request is assigned a unique identifying number. The first two digits of this number give the year the request was initiated. All requests for a given Isotope and Quantity are grouped (or blocked) together. The requests in a block are followed by any status comments. Each request has a unique Isotope, Quantity and Requester. The requester is identified by laboratory, last name, and sponsoring US government agency, e.g., BET, DEI, DNR. All requesters, together with their addresses and phone numbers, are given in appendix B. A list of the evaluators responsible for ENDF/B-V evaluations with their affiliation appears in appendix C. All requests must give the energy (or range of energy) for the incident particle when appropriate. The accuracy needed in percent is also given. The error quoted is assumed to be 1-sigma at each measured point in the energy range requested unless a comment specifies otherwise. Sometimes a range of accuracy indicated by two values is given or some statement is given in the free text comments. An incident particle energy resolution in percent is sometimes given

Architectural and compiler techniques for energy reduction in high-performance microprocessors

Science.gov (United States)

Bellas, Nikolaos

1999-11-01

The microprocessor industry has started viewing power, along with area and performance, as a decisive design factor in today's microprocessors. The increasing cost of packaging and cooling systems poses stringent requirements on the maximum allowable power dissipation. Most of the research in recent years has focused on the circuit, gate, and register-transfer (RT) levels of the design. In this research, we focus on the software running on a microprocessor and we view the program as a power consumer. Our work concentrates on the role of the compiler in the construction of "power-efficient" code, and especially its interaction with the hardware so that unnecessary processor activity is saved. We propose techniques that use extra hardware features and compiler-driven code transformations that specifically target activity reduction in certain parts of the CPU which are known to be large power and energy consumers. Design for low power/energy at this level of abstraction entails larger energy gains than in the lower stages of the design hierarchy in which the design team has already made the most important design commitments. The role of the compiler in generating code which exploits the processor organization is also fundamental in energy minimization. Hence, we propose a hardware/software co-design paradigm, and we show what code transformations are necessary by the compiler so that "wasted" power in a modern microprocessor can be trimmed. More specifically, we propose a technique that uses an additional mini cache located between the instruction cache (I-Cache) and the CPU core; the mini cache buffers instructions that are nested within loops and are continuously fetched from the I-Cache. This mechanism can create very substantial energy savings, since the I-Cache unit is one of the main power consumers in most of today's high-performance microprocessors. Results are reported for the SPEC95 benchmarks in the R-4400 processor which implements the MIPS2 instruction

In high-performance computing systems, parallel I/O architectures usually have very complex hierarchies with multiple layers that collectively constitute an I/O stack, including high-level I/O libraries such as PnetCDF and HDF5, I/O middleware such as MPI-IO, and parallel file systems such as PVFS and Lustre. Our project explored automated instrumentation and compiler support for I/O intensive applications. Our project made significant progress towards understanding the complex I/O hierarchies of high-performance storage systems (including storage caches, HDDs, and SSDs), and designing and implementing state-of-the-art compiler/runtime system technology that targets I/O intensive HPC applications that target leadership class machine. This final report summarizes the major achievements of the project and also points out promising future directions.

Just-in-Time Compilation-Inspired Methodology for Parallelization of Compute Intensive Java Code

Directory of Open Access Journals (Sweden)

GHULAM MUSTAFA

2017-01-01

Full Text Available Compute intensive programs generally consume significant fraction of execution time in a small amount of repetitive code. Such repetitive code is commonly known as hotspot code. We observed that compute intensive hotspots often possess exploitable loop level parallelism. A JIT (Just-in-Time compiler profiles a running program to identify its hotspots. Hotspots are then translated into native code, for efficient execution. Using similar approach, we propose a methodology to identify hotspots and exploit their parallelization potential on multicore systems. Proposed methodology selects and parallelizes each DOALL loop that is either contained in a hotspot method or calls a hotspot method. The methodology could be integrated in front-end of a JIT compiler to parallelize sequential code, just before native translation. However, compilation to native code is out of scope of this work. As a case study, we analyze eighteen JGF (Java Grande Forum benchmarks to determine parallelization potential of hotspots. Eight benchmarks demonstrate a speedup of up to 7.6x on an 8-core system

Proposed methodology selects and parallelizes each DOALL loop that is either contained in a hotspot method or calls a hotspot method. The methodology could be integrated in front-end of a JIT compiler to parallelize sequential code, just before native translation. However, compilation to native code is out of scope of this work. As a case study, we analyze eighteen JGF (Java Grande Forum) benchmarks to determine parallelization potential of hotspots. Eight benchmarks demonstrate a speedup of up to 7.6x on an 8-core system.

Recent advances in PC-Linux systems for electronic structure computations by optimized compilers and numerical libraries.

Science.gov (United States)

Yu, Jen-Shiang K; Yu, Chin-Hui

2002-01-01

One of the most frequently used packages for electronic structure research, GAUSSIAN 98, is compiled on Linux systems with various hardware configurations, including AMD Athlon (with the "Thunderbird" core), AthlonMP, and AthlonXP (with the "Palomino" core) systems as well as the Intel Pentium 4 (with the "Willamette" core) machines. The default PGI FORTRAN compiler (pgf77) and the Intel FORTRAN compiler (ifc) are respectively employed with different architectural optimization options to compile GAUSSIAN 98 and test the performance improvement. In addition to the BLAS library included in revision A.11 of this package, the Automatically Tuned Linear Algebra Software (ATLAS) library is linked against the binary executables to improve the performance. Various Hartree-Fock, density-functional theories, and the MP2 calculations are done for benchmarking purposes. It is found that the combination of ifc with ATLAS library gives the best performance for GAUSSIAN 98 on all of these PC-Linux computers, including AMD and Intel CPUs. Even on AMD systems, the Intel FORTRAN compiler invariably produces binaries with better performance than pgf77. The enhancement provided by the ATLAS library is more significant for post-Hartree-Fock calculations. The performance on one single CPU is potentially as good as that on an Alpha 21264A workstation or an SGI supercomputer. The floating-point marks by SpecFP2000 have similar trends to the results of GAUSSIAN 98 package.

MÉTODOS: Testou-se através de discos de antibiograma e ação em bactérias formadoras de biofilme a ação antimicrobiana de algumas soluções de Ca(OH2 e tergentol usando-se como padrão-ouro o digluconato de clorexidina a 0,12%. RESULTADOS: Os resultados foram analisados através do teste de Kruskal-Wallis e do pós-teste de comparação múltipla de Dunn com valores de p sempre menores que 0,05. A clorexidina obteve melhores resultados em nível de ação antimicrobiana em relação às soluções a base de Ca(OH2 e tergentol. A diferença estatísta da ação da clorexidina frente às demais soluções e aos tipos bacterianos testados não foi significativa para a maiorias dos cruzamentos. CONCLUSÕES: O digluconato de clorexidina a 0,12% foi o egente antimicrobiano mais efetivo neste estudo. As soluções a base de hidróxido de cálcio não apresentaram efetividade satisfatória em relação a clorexidina, principalmente em relação ao Streptococcus mutans. São necessários estudos mais aprofundados para se determinar o real potencial do HCT 20 como anti-séptico bucal.PURPOSES: This research desenvolved in Rio Grande do Norte Federal University, Department of Dentistry purpose evaluation "in vitro" Ca(OH2 and tergentol solutions action in oral cavity that first reside in and cariogenic microorganisms for dental biofilm chemical control increasing.

HOPE: A Python just-in-time compiler for astrophysical computations

Science.gov (United States)

Akeret, J.; Gamper, L.; Amara, A.; Refregier, A.

2015-04-01

The Python programming language is becoming increasingly popular for scientific applications due to its simplicity, versatility, and the broad range of its libraries. A drawback of this dynamic language, however, is its low runtime performance which limits its applicability for large simulations and for the analysis of large data sets, as is common in astrophysics and cosmology. While various frameworks have been developed to address this limitation, most focus on covering the complete language set, and either force the user to alter the code or are not able to reach the full speed of an optimised native compiled language. In order to combine the ease of Python and the speed of C++, we developed HOPE, a specialised Python just-in-time (JIT) compiler designed for numerical astrophysical applications. HOPE focuses on a subset of the language and is able to translate Python code into C++ while performing numerical optimisation on mathematical expressions at runtime. To enable the JIT compilation, the user only needs to add a decorator to the function definition. We assess the performance of HOPE by performing a series of benchmarks and compare its execution speed with that of plain Python, C++ and the other existing frameworks. We find that HOPE improves the performance compared to plain Python by a factor of 2 to 120, achieves speeds comparable to that of C++, and often exceeds the speed of the existing solutions. We discuss the differences between HOPE and the other frameworks, as well as future extensions of its capabilities. The fully documented HOPE package is available at http://hope.phys.ethz.ch and is published under the GPLv3 license on PyPI and GitHub.

Neste estudo, objetivou-se caracterizar a diversidade de bactérias diazotróficas endofíticas associadas a plantas de milho em diferentes locais do Rio Grande do Sul, que apresentavam variações de clima e solo. Para isso, foi usado um método baseado na amplificação do gene nifH grupo I, na análise de fragmentos de restrição (PCR-RFLP e no seqüenciamento dos genes amplificados. Foram calculados os índices de Shannon-Weaver e Equitabilidade para estimar a diversidade dos diazotróficos, bem como a diversidade de nucleotídeos e divergência entre seqüências, para estimar a diversidade genética das comunidades amostradas. Na avaliação da diferenciação entre as comunidades foi utilizado o teste F ST. Foi detectada maior variação entre as comunidades das diferentes regiões do Estado do que dentro das comunidades de cada região avaliada, particularmente entre comunidades provenientes de diferentes tipos de solo, regime pluviométrico e regiões geográficas. O índice de diversidade de Shannon-Weaver indicou diferenças em termos de diversidade de unidades taxonômicas entre as comunidades avaliadas. As comunidades amostradas da região norte do Rio Grande do Sul, que mostrou maior disponibilidade de água e conteúdo de argila, tenderam a apresentar maior diversidade quando comparada às comunidades amostradas na região sul. A análise de Equitabilidade mostrou a dominância de unidades taxonômicas dentro de cada comunidade avaliada, independentemente da região amostrada. Todas as seqüências obtidas foram classificadas como pertencentes ao gene nifH grupo I. Foram obtidas seqüências pertencentes às classes Alfa, Beta e Gama-proteobactéria. Esses resultados demonstraram que existe grande diversidade de bactérias endofíticas fixadoras de N

Full Text Available O laser de baixa potência vem sendo usado para acelerar a cicatrização em úlceras de pressão devido a seus efeitos cicatrizante, antiinflamatório, antiedematoso e analgésico. No entanto, não há consenso quanto a seu efeito em úlceras infectadas. O objetivo deste estudo foi verificar o efeito bactericida da laserterapia e da terapia fotodinâmica (TFD com laser de baixa potência, InGaP, 670 nm, em doses de 2, 4 e 6 J/cm², em bactérias gram-positivas e gram-negativas in vitro. Foram preparadas 32 placas de Petri com bactérias, 16 com Pseudomonas aeruginosa e 16 com Staphilococcus aureus. Aleatoriamente dividiu-se cada grupo em oito subgrupos (duas placas cada: três subgrupos tratados só com laserterapia, em doses de 2 J/cm², 4 J/cm² e 6 J/cm²; três subgrupos tratados com TFD, em doses de 2 J/cm², 4 J/cm² e 6 J/cm²; um tratado apenas com fotossensibilizante (azul de metileno a 0,1 µg/ml; e um subgrupo não tratado (controle. Os subgrupos laser e TFD foram irradiados uma única vez e incubados por 24 horas. Os outros dois subgrupos não receberam irradiação. As culturas foram analisadas visualmente para verificação ou não do halo de inibição. Em todos os subgrupos, de ambas as bactérias, não foi observado qualquer halo de inibição nem de crescimento. Conclui-se que a terapia a laser e a fotodinâmica de baixa potência (InGaP, 670 nm não produziram efeitos bactericidas e/ou bacteriostáticos, tampouco tendo havido efeito bioestimulante sobre as bactérias.Low-level laser therapy has been used to speed up healing process of pressure ulcers due to its antiinflammatory, analgesic, anti-edematous, and scarring effects.

In high-performance computing (HPC), parallel I/O architectures usually have very complex hierarchies with multiple layers that collectively constitute an I/O stack, including high-level I/O libraries such as PnetCDF and HDF5, I/O middleware such as MPI-IO, and parallel file systems such as PVFS and Lustre. Our DOE project explored automated instrumentation and compiler support for I/O intensive applications. Our project made significant progress towards understanding the complex I/O hierarchies of high-performance storage systems (including storage caches, HDDs, and SSDs), and designing and implementing state-of-the-art compiler/runtime system technology that targets I/O intensive HPC applications that target leadership class machine. This final report summarizes the major achievements of the project and also points out promising future directions Two new sections in this report compared to the previous report are IOGenie and SSD/NVM-specific optimizations.

Scalability and connectivity are two key challenges in designing neuromorphic hardware that can match biological levels. In this paper, we describe a neuromorphic system architecture design that addresses an approach to meet these challenges using traditional complementary metal-oxide-semiconductor (CMOS) hardware. A key requirement in realizing such neural architectures in hardware is the ability to automatically configure the hardware to emulate any neural architecture or model. The focus for this paper is to describe the details of such a programmable front-end. This programmable front-end is composed of a neuromorphic compiler and a digital memory, and is designed based on the concept of synaptic time-multiplexing (STM). The neuromorphic compiler automatically translates any given neural architecture to hardware switch states and these states are stored in digital memory to enable desired neural architectures. STM enables our proposed architecture to address scalability and connectivity using traditional CMOS hardware. We describe the details of the proposed design and the programmable front-end, and provide examples to illustrate its capabilities. We also provide perspectives for future extensions and potential applications.

Numerical performance and throughput benchmark for electronic structure calculations in PC-Linux systems with new architectures, updated compilers, and libraries.

A number of recently released numerical libraries including Automatically Tuned Linear Algebra Subroutines (ATLAS) library, Intel Math Kernel Library (MKL), GOTO numerical library, and AMD Core Math Library (ACML) for AMD Opteron processors, are linked against the executables of the Gaussian 98 electronic structure calculation package, which is compiled by updated versions of Fortran compilers such as Intel Fortran compiler (ifc/efc) 7.1 and PGI Fortran compiler (pgf77/pgf90) 5.0. The ifc 7.1 delivers about 3% of improvement on 32-bit machines compared to the former version 6.0. Performance improved from pgf77 3.3 to 5.0 is also around 3% when utilizing the original unmodified optimization options of the compiler enclosed in the software. Nevertheless, if extensive compiler tuning options are used, the speed can be further accelerated to about 25%. The performances of these fully optimized numerical libraries are similar. The double-precision floating-point (FP) instruction sets (SSE2) are also functional on AMD Opteron processors operated in 32-bit compilation, and Intel Fortran compiler has performed better optimization. Hardware-level tuning is able to improve memory bandwidth by adjusting the DRAM timing, and the efficiency in the CL2 mode is further accelerated by 2.6% compared to that of the CL2.5 mode. The FP throughput is measured by simultaneous execution of two identical copies of each of the test jobs. Resultant performance impact suggests that IA64 and AMD64 architectures are able to fulfill significantly higher throughput than the IA32, which is consistent with the SpecFPrate2000 benchmarks.

2012-11-01

Herbal hepatotoxicity is a field that has rapidly grown over the last few years along with increased use of herbal products worldwide. To summarize the various facets of this disease, we undertook a literature search for herbs, herbal drugs and herbal supplements with reported cases of herbal hepatotoxicity. A selective literature search was performed to identify published case reports, spontaneous case reports, case series and review articles regarding herbal hepatotoxicity. A total of 185 publications were identified and the results compiled. They show 60 different herbs, herbal drugs and herbal supplements with reported potential hepatotoxicity, additional information including synonyms of individual herbs, botanical names and cross references are provided. If known, details are presented for specific ingredients and chemicals in herbal products, and for references with authors that can be matched to each herbal product and to its effect on the liver. Based on stringent causality assessment methods and/or positive re-exposure tests, causality was highly probable or probable for Ayurvedic herbs, Chaparral, Chinese herbal mixture, Germander, Greater Celandine, green tea, few Herbalife products, Jin Bu Huan, Kava, Ma Huang, Mistletoe, Senna, Syo Saiko To and Venencapsan(®). In many other publications, however, causality was not properly evaluated by a liver-specific and for hepatotoxicity-validated causality assessment method such as the scale of CIOMS (Council for International Organizations of Medical Sciences). This compilation presents details of herbal hepatotoxicity, assisting thereby clinical assessment of involved physicians in the future. © 2012 John Wiley & Sons A/S.

Guide to Good Practice in using Open Source Compilers with the AGCC Lexical Analyzer

2009-01-01

Full Text Available Quality software always demands a compromise between users' needs and hardware resources. To be faster means expensive devices like powerful processors and virtually unlimited amounts of RAM memory. Or you just need reengineering of the code in terms of adapting that piece of software to the client's hardware architecture. This is the purpose of optimizing code in order to get the utmost software performance from a program in certain given conditions. There are tools for designing and writing the code but the ultimate tool for optimizing remains the modest compiler, this often neglected software jewel the result of hundreds working hours by the best specialists in the world. Even though, only two compilers fulfill the needs of professional developers, a proprietary solution from a giant in the IT industry, and the Open source GNU compiler, for which we develop the AGCC lexical analyzer that helps producing even more efficient software applications. It relies on the most popular hacks and tricks used by professionals and discovered by the author who are proud to present them further below.

Computer and compiler effects on code results: status report

International Nuclear Information System (INIS)

1996-01-01

Within the framework of the international effort on the assessment of computer codes, which are designed to describe the overall reactor coolant system (RCS) thermalhydraulic response, core damage progression, and fission product release and transport during severe accidents, there has been a continuous debate as to whether the code results are influenced by different code users or by different computers or compilers. The first aspect, the 'Code User Effect', has been investigated already. In this paper the other aspects will be discussed and proposals are given how to make large system codes insensitive to different computers and compilers. Hardware errors and memory problems are not considered in this report. The codes investigated herein are integrated code systems (e. g. ESTER, MELCOR) and thermalhydraulic system codes with extensions for severe accident simulation (e. g. SCDAP/RELAP, ICARE/CATHARE, ATHLET-CD), and codes to simulate fission product transport (e. g. TRAPMELT, SOPHAEROS). Since all of these codes are programmed in Fortran 77, the discussion herein is based on this programming language although some remarks are made about Fortran 90. Some observations about different code results by using different computers are reported and possible reasons for this unexpected behaviour are listed. Then methods are discussed how to avoid portability problems

The software of automotive control systems has become increasingly large and complex. High level languages (primarily C) and the compilers become more important to reduce coding time. Most compilers represent real number in the floating point format specified by IEEE standard 754. Most microprocessors in the automotive industry have no hardware for the operation using the IEEE standard due to the cost requirements, resulting in the slow execution speed and large code size. Alternative formats to increase execution speed and reduce code size are proposed. Experimental results for the alternative formats show the improvement in execution speed and code size. 4 refs., 3 figs., 2 tabs.

Full Text Available The genetic diversity of siderophore-producing bacteria of tobacco rhizosphere was studied by amplified ribosomal DNA restriction analysis (ARDRA, 16S rRNA sequence homology and phylogenetics analysis methods. Studies demonstrated that 85% of the total 354 isolates produced siderophores in iron limited liquid medium. A total of 28 ARDRA patterns were identified among the 299 siderophore-producing bacterial isolates. The 28 ARDRA patterns represented bacteria of 14 different genera belonging to six bacterial divisions, namely ?-, ?-, ?-Proteobacteria, Sphingobacteria, Bacilli,and Actinobacteria. Especially, ?-Proteobacteria consisting of Pseudomonas, Enterobacter, Serratia, Pantoea, Erwinia and Stenotrophomonasgenus encountered 18 different ARDRA groups. Results also showed a greater siderophore-producing bacterial diversity than previous researches. For example, Sphingobacterium (isolates G-2-21-1 and G-2-27-2, Pseudomonas poae (isolate G-2-1-1, Enterobacter endosymbiont (isolates G-2-10-2 and N-5-10, Delftia acidovorans (isolate G-1-15, and Achromobacter xylosoxidans (isolates N-46-11HH and N-5-20 were reported to be able to producesiderophores under low-iron conditions for the first time. Gram-negative isolates were more frequently encountered, with more than 95% total frequency. For Gram-positive bacteria, the Bacillus and Rhodococcus were the only two genera, with 1.7% total frequency. Furthermore, the Pseudomonas and Enterobacter were dominant in this environment, with 44.5% and 24.7% total frequency, respectively. It was also found that 75 percent of the isolates that had the high percentages of siderophore units (% between 40 and 60 belonged to Pseudomonas. Pseudomonas sp. G-229-21 screened out in this study may have potential to apply to low-iron soil to prevent plant soil-borne fungal pathogen diseases.A diversidade genética de bactérias de rizosfera de tabaco produtoras de sideróforos foi estudada por meio da técnica de análise de

Northern hemisphere mid-latitude geomagnetic anomaly revealed from Levantine Archaeomagnetic Compilation (LAC).

The rich archaeological heritage of Israel and nearby Levantine countries provides a unique opportunity for archaeomagnetic investigation in high resolution. Here we present a summary of our ongoing effort to reconstruct geomagnetic variations of the past several millennia in the Levant at decadal to millennial resolution. This effort at the Southern Levant, namely the "Levantine Archaeomagnetic Compilation" (LAC), presently consists of data from over 650 well-dated archaeological objects including pottery, slag, ovens, and furnaces. In this talk we review the methodological challenges in achieving a robust master secular variation curve with realistic error estimations from a large number of different datasets. We present the current status of the compilation, including the southern and western Levant LAC data (Israel, Cyprus, and Jordan) and other published north-eastern Levant data (Syria and southern Turkey), and outline the main findings emerging from these data. The main feature apparent from the new compilation is an extraordinary intensity high that developed over the Levant region during the first two millennia BCE. The climax of this event is a double peak intensity maximum starting at ca. 1000 BCE and ending at ca. 735 BCE, accompanied with at least two events of geomagnetic spikes. Paleomagnetic directions from this period demonstrate anomalies of up to 20 degrees far from the averaged GAD field. This leads us to postulate that the maximum in the intensity is a manifestation of an intense mid-latitude local positive geomagnetic anomaly that persisted for over two centuries.

The NEA Data Bank is an international centre of reference for basic nuclear tools used in the analysis and prediction of phenomena in different nuclear applications. The Data Bank collects and compiles computer codes and scientific data and contributes to their improvement for the benefit of scientists in its member countries. In line with this mission, the Data Bank is a core centre of the International Network of Nuclear Reaction Data Centres (NRDC), which co-ordinates the worldwide collection, compilation and dissemination of nuclear reaction data. The NRDC network was established in 1976 from the earlier Four-Centres' Network created in 1966 by the United States, the NEA, the International Atomic Energy Agency (IAEA) and the former Soviet Union. Today, the NRDC is a worldwide co-operation network under the auspices of the IAEA, with 14 nuclear data centres from 8 countries and 2 international organisations belonging to the network. The main objective of the NRDC is to preserve, update and disseminate experimental nuclear reaction data that have been compiled for more than 40 years in a shared database (EXFOR). The EXFOR database contains basic nuclear data on low- to medium-energy experiments for incident neutron, photon and various charged-particle-induced reactions on a wide range of isotopes, natural elements and compounds. Today, with more than 140 000 data sets from approximately 20 000 experiments, EXFOR is by far the most important and complete experimental nuclear reaction database in the world and is widely used in the field of nuclear science and technology. The Data Bank is responsible for the collection and compilation of nuclear reaction data measured in its geographical area. Since 1966, the Data Bank has contributed around 5 000 experiments to the EXFOR database, and it continues to compile new data while maintaining the highest level of quality throughout the database. NRDC co-ordination meetings are held on a biennial basis. Recent meetings

Full Text Available Guava leaf tea of Psidium guajava Linnaeus is commonly used as a medicine against gastroenteritis and child diarrhea by those who cannot afford or do not have access to antibiotics. This study screened the antimicrobial effect of essential oils and methanol, hexane, ethyl acetate extracts from guava leaves. The extracts were tested against diarrhea-causing bacteria: Staphylococcus aureus, Salmonella spp. and Escherichia coli. Strains that were screened included isolates from seabob shrimp, Xiphopenaeus kroyeri (Heller and laboratory-type strains. Of the bacteria tested, Staphylococcus aureus strains were most inhibited by the extracts. The methanol extract showed greatest bacterial inhibition. No statistically significant differences were observed between the tested extract concentrations and their effect. The essential oil extract showed inhibitory activity against S. aureus and Salmonella spp. The strains isolated from the shrimp showed some resistance to commercially available antibiotics. These data support the use of guava leaf-made medicines in diarrhea cases where access to commercial antibiotics is restricted. In conclusion, guava leaf extracts and essential oil are very active against S. aureus, thus making up important potential sources of new antimicrobial compounds.O chá de folhas de goiaba Psidium guajava Linnaeus é comumente usado como remédio nas gastrenterites e diarréias infantis por aqueles que não têm acesso a antibióticos.

The production of the CARETS map data base involved the development of a series of procedures for interpreting, compiling, and verifying data obtained from remote sensor sources. Level II land use mapping from high-altitude aircraft photography at a scale of 1:100,000 required production of a photomosaic mapping base for each of the 48, 50 x 50 km sheets, and the interpretation and coding of land use polygons on drafting film overlays. CARETS researchers also produced a series of 1970 to 1972 land use change overlays, using the 1970 land use maps and 1972 high-altitude aircraft photography. To enhance the value of the land use sheets, researchers compiled series of overlays showing cultural features, county boundaries and census tracts, surface geology, and drainage basins. In producing Level I land use maps from Landsat imagery, at a scale of 1:250,000, interpreters overlaid drafting film directly on Landsat color composite transparencies and interpreted on the film. They found that such interpretation involves pattern and spectral signature recognition. In studies using Landsat imagery, interpreters identified numerous areas of change but also identified extensive areas of "false change," where Landsat spectral signatures but not land use had changed.

The compilation of data of single pion photoproduction experiment below 2 GeV is presented with the keywords which specify the experiment. These data are written on a magnetic tape. Data format and the indices for the keywords are given. Various programs of using this tape are also presented. The results of the compilation are divided into two types. The one is the reference card on which the information of the experiment is given. The other is the data card. These reference and data cards are written using all A-type format on an original tape. The copy tapes are available, which are written by various types on request. There are two kinds of the copy tapes. The one is same as the original tape, and the other is the one different in the data card. Namely, this card is written by F-type following the data type. One experiment on this tape is represented by 3 kinds of the cards. One reference card with A-type format, many data cards with F-type format and one identifying card. Various programs which are written by FORTRAN are ready for these original and copy tapes. (Kato, T.)

Basic circuit compilation techniques for an ion-trap quantum machine

International Nuclear Information System (INIS)

Maslov, Dmitri

2017-01-01

We study the problem of compilation of quantum algorithms into optimized physical-level circuits executable in a quantum information processing (QIP) experiment based on trapped atomic ions. We report a complete strategy: starting with an algorithm in the form of a quantum computer program, we compile it into a high-level logical circuit that goes through multiple stages of decomposition into progressively lower-level circuits until we reach the physical execution-level specification. We skip the fault-tolerance layer, as it is not within the scope of this work. The different stages are structured so as to best assist with the overall optimization while taking into account numerous optimization criteria, including minimizing the number of expensive two-qubit gates, minimizing the number of less expensive single-qubit gates, optimizing the runtime, minimizing the overall circuit error, and optimizing classical control sequences. Our approach allows a trade-off between circuit runtime and quantum error, as well as to accommodate future changes in the optimization criteria that may likely arise as a result of the anticipated improvements in the physical-level control of the experiment.

Innovative strategies that facilitate the use of high quality practice guidelines (PG) are needed. Accordingly, repositories designed to simplify access to PGs have been proposed as a critical component of the network of linked interventions needed to drive increased PG implementation. The National Guideline Clearinghouse (NGC) is a free, international online repository. We investigated whether it is a trustworthy source of child and youth anxiety and depression PGs. English language PGs published between January 2009 and February 2016 relevant to anxiety or depression in children and adolescents (≤ 18 years of age) were eligible. Two trained raters assessed PG quality using Appraisal of Guidelines for Research and Evaluation (AGREE II). Scores on at least three AGREE II domains (stakeholder involvement, rigor of development, and editorial independence) were used to designate PGs as: i) minimum quality (≥ 50%); and ii) high quality (≥ 70%). Eight eligible PGs were identified (depression, n=6; anxiety and depression, n=1; social anxiety disorder, n=1). Four of eight PGs met minimum quality criteria; three of four met high quality criteria. At present, NGC users without the time and special skills required to evaluate PG quality may unknowingly choose flawed PGs to guide decisions about child and youth anxiety and depression. The recent NGC decision to explore the inclusion of PG quality profiles based on Institute of Medicine standards provides needed leadership that can strengthen PG repositories, prevent harm and wasted resources, and build PG developer capacity.

Full Text Available Abstract: Developing and documenting the eleven official languages of South Africa on all levels of communication in order to fulfil all the roles and uses characteristic of truly official languages is a great challenge. To meet this need various bodies such as the National Lexicography Units have been established by the Pan South African Language Board (PanSALB. As far as dictionary compilation is concerned, acquaintance with the state-of-the-art developments in the theory and practice of lexicography is necessary. The focus of the African languages should be directed onto the compilation of monolingual dictionaries. It is important that these monolingual dictionaries should be usable right from the start on a continuous basis. Continued attention should be given to enlarging the corpora and actual consultation of these corpora on the macro- and microstructural levels. The end-products should be of a high lexicographic standard, well-balanced in terms of lemma selection, length of the articles, maximum utilisation of available dictionary space etc. They should also be planned and compiled in such a way that the transition from paper dictionaries to electronic dictionaries could be easily and naturally accomplished. Advanced and continued training in the compilation of monolingual dictionaries should be presented.

Esta propriedade conservante das especiarias está relacionada com a presença de compostos antibacterianos na sua composição. Tais compostos podem ser usados no combate a bactérias deteriorantes de alimentos, por esse motivo, este trabalho visa à investigação da propriedade antimicrobiana dos óleos essenciais de Cinnamomum zeylanicum Blume, Coriandrum sativum L., Cuminum cyminum L., Mentha. piperita L., Ocimum basilicum L., Origanum majorana L., Pimpinella anisum L., Piper nigrum L., Rosmarinus officinalis L. e Zingiber officinalis Rosc. frente a bactérias contaminantes de alimentos. Para esse estudo, foram selecionadas 10 cepas bacterianas deteriorantes de alimentos. Para a realização dos ensaios antibacterianos, foi utilizado o método de difusão em meio sólido. Os resultados mostram que os óleos essenciais das folhas do E. caryophyllata e da C. zeylanicum mostraram uma eficiência na inibição de todas as cepas bacterianas ensaiadas. Os outros óleos produziram atividade antibacteriana, porém com menor espectro de ação. A pesquisa de tais produtos mostra-se bastante promissora, sendo essa uma boa alternativa para a substituição de aditivos químicos em alimentos.Spices are known for their stability against microbial action; that being so, they are included in the group of stable foods.

This paper describes a compiler approach to introducing communication-avoiding optimizations in geometric multigrid (GMG), one of the most popular methods for solving partial differential equations. Communication-avoiding optimizations reduce vertical communication through the memory hierarchy and horizontal communication across processes or threads, usually at the expense of introducing redundant computation. We focus on applying these optimizations to the smooth operator, which successively reduces the error and accounts for the largest fraction of the GMG execution time. Our compiler technology applies both novel and known transformations to derive an implementation comparable to manually-tuned code. To make the approach portable, an underlying autotuning system explores the tradeoff between reduced communication and increased computation, as well as tradeoffs in threading schemes, to automatically identify the best implementation for a particular architecture and at each computation phase. Results show that we are able to quadruple the performance of the smooth operation on the finest grids while attaining performance within 94% of manually-tuned code. Overall we improve the overall multigrid solve time by 2.5× without sacrificing programer productivity.

Aeromagnetic map compilation: procedures for merging and an example from Washington

Directory of Open Access Journals (Sweden)

C. Finn

2000-06-01

Full Text Available Rocks in Antarctica and offshore have widely diverse magnetic properties. Consequently, aeromagnetic data collected there can improve knowledge of the geologic, tectonic and geothermal characteristics of the region. Aeromagnetic data can map concealed structures such as faults, folds and dikes, ascertain basin thickness and locate buried volcanic, as well as some intrusive and metamorphic rocks. Gridded, composite data sets allow a view of continental-scale trends that individual data sets do not provide and link widely-separated areas of outcrop and disparate geologic studies. Individual magnetic surveys must be processed so that they match adjacent surveys prior to merging. A consistent representation of the Earth's magnetic field (International Geomagnetic Reference Field (IGRF must be removed from each data set. All data sets need to be analytically continued to the same flight elevation with their datums shifted to match adjacent data. I advocate minimal processing to best represent the individual surveys in the merged compilation. An example of a compilation of aeromagnetic surveys from Washington illustrates the utility of aeromagnetic maps for providing synoptic views of regional tectonic features.

Brown-Vialetto-Van Laere syndrome represents a phenotypic spectrum of motor, sensory, and cranial nerve neuropathy, often with ataxia, optic atrophy and respiratory problems leading to ventilator-dependence. Loss-of-function mutations in two riboflavin transporter genes, SLC52A2 and SLC52A3, have recently been linked to Brown-Vialetto-Van Laere syndrome. However, the genetic frequency, neuropathology and downstream consequences of riboflavin transporter mutations are unclear. By screening a large cohort of 132 patients with early-onset severe sensory, motor and cranial nerve neuropathy we confirmed the strong genetic link between riboflavin transporter mutations and Brown-Vialetto-Van Laere syndrome, identifying 22 pathogenic mutations in SLC52A2 and SLC52A3, 14 of which were novel. Brain and spinal cord neuropathological examination of two cases with SLC52A3 mutations showed classical symmetrical brainstem lesions resembling pathology seen in mitochondrial disease, including severe neuronal loss in the lower cranial nerve nuclei, anterior horns and corresponding nerves, atrophy of the spinothalamic and spinocerebellar tracts and posterior column-medial lemniscus pathways. Mitochondrial dysfunction has previously been implicated in an array of neurodegenerative disorders. Since riboflavin metabolites are critical components of the mitochondrial electron transport chain, we hypothesized that reduced riboflavin transport would result in impaired mitochondrial activity, and confirmed this using in vitro and in vivo models. Electron transport chain complex I and complex II activity were decreased in SLC52A2 patient fibroblasts, while global knockdown of the single Drosophila melanogaster riboflavin transporter homologue revealed reduced levels of riboflavin, downstream metabolites, and electron transport chain complex I activity. This in turn led to abnormal mitochondrial membrane potential, respiratory chain activity and morphology. Riboflavin transporter knockdown in

ccPDB (http://crdd.osdd.net/raghava/ccpdb/) is a database of data sets compiled from the literature and Protein Data Bank (PDB). First, we collected and compiled data sets from the literature used for developing bioinformatics methods to annotate the structure and function of proteins. Second, data sets were derived from the latest release of PDB using standard protocols. Third, we developed a powerful module for creating a wide range of customized data sets from the current release of PDB. This is a flexible module that allows users to create data sets using a simple six step procedure. In addition, a number of web services have been integrated in ccPDB, which include submission of jobs on PDB-based servers, annotation of protein structures and generation of patterns. This database maintains >30 types of data sets such as secondary structure, tight-turns, nucleotide interacting residues, metals interacting residues, DNA/RNA binding residues and so on.

Sharing analysis in the Pawns compiler

Directory of Open Access Journals (Sweden)

Lee Naish

2015-09-01

Full Text Available Pawns is a programming language under development that supports algebraic data types, polymorphism, higher order functions and “pure” declarative programming. It also supports impure imperative features including destructive update of shared data structures via pointers, allowing significantly increased efficiency for some operations. A novelty of Pawns is that all impure “effects” must be made obvious in the source code and they can be safely encapsulated in pure functions in a way that is checked by the compiler. Execution of a pure function can perform destructive updates on data structures that are local to or eventually returned from the function without risking modification of the data structures passed to the function. This paper describes the sharing analysis which allows impurity to be encapsulated. Aspects of the analysis are similar to other published work, but in addition it handles explicit pointers and destructive update, higher order functions including closures and pre- and post-conditions concerning sharing for functions.

Molecular dynamics and diffusion a compilation

CERN Document Server

Fisher, David

2013-01-01

The molecular dynamics technique was developed in the 1960s as the outgrowth of attempts to model complicated systems by using either a) direct physical simulation or (following the great success of Monte Carlo methods) by b) using computer techniques. Computer simulation soon won out over clumsy physical simulation, and the ever-increasing speed and sophistication of computers has naturally made molecular dynamics simulation into a more and more successful technique. One of its most popular applications is the study of diffusion, and some experts now even claim that molecular dynamics simulation is, in the case of situations involving well-characterised elements and structures, more accurate than experimental measurement. The present double volume includes a compilation (over 600 items) of predicted solid-state diffusion data, for all of the major materials groups, dating back nearly four decades. The double volume also includes some original papers: "Determination of the Activation Energy for Formation and ...

Compilation of Existing Neutron Screen Technology

Directory of Open Access Journals (Sweden)

N. Chrysanthopoulou

2014-01-01

Full Text Available The presence of fast neutron spectra in new reactors is expected to induce a strong impact on the contained materials, including structural materials, nuclear fuels, neutron reflecting materials, and tritium breeding materials. Therefore, introduction of these reactors into operation will require extensive testing of their components, which must be performed under neutronic conditions representative of those expected to prevail inside the reactor cores when in operation. Due to limited availability of fast reactors, testing of future reactor materials will mostly take place in water cooled material test reactors (MTRs by tailoring the neutron spectrum via neutron screens. The latter rely on the utilization of materials capable of absorbing neutrons at specific energy. A large but fragmented experience is available on that topic. In this work a comprehensive compilation of the existing neutron screen technology is attempted, focusing on neutron screens developed in order to locally enhance the fast over thermal neutron flux ratio in a reactor core.

2010-01-01

The Nuclear Energy Division of the Institute for Advanced Studies (IEAv) is conducting the TERRA project (TEcnologia de Reatores Rapidos Avancados), Technology for Advanced Fast Reactors project, aimed at a space reactor application. In this work, to attend the TERRA project, the NALAP code adapted to a microcomputer compiler called Compaq Visual Fortran (Version 6.6) is presented. This code, adapted from the light water reactor transient code RELAP 3B, simulates thermal-hydraulic responses for sodium cooled fast reactors. The strategy to run the code in a PC was divided in some steps mainly to remove unnecessary routines, to eliminate old statements, to introduce new ones and also to include extension precision mode. The source program was able to solve three sample cases under conditions of protected transients suggested in literature: the normal reactor shutdown, with a delay of 200 ms to start the control rod movement and a delay of 500 ms to stop the pumps; reactor scram after transient of loss of flow; and transients protected from overpower. Comparisons were made with results from the time when the NALAP code was acquired by the IEAv, back in the 80's. All the responses for these three simulations reproduced the calculations performed with the CDC compiler in 1985. Further modifications will include the usage of gas as coolant for the nuclear reactor to allow a Closed Brayton Cycle Loop - CBCL - to be used as a heat/electric converter. (author)

L'infection urinaire chez l'insuffisant rénal est fréquente et particulière dans sa prise en charge diagnostique et thérapeutique. L'objectif de notre étude est de déterminer le profil bactériologique et d’étudier les facteurs de risque des infections urinaires chez le patient insuffisant rénal chronique en milieu de néphrologie. Etude prospective débutée en Septembre 2012 menée au service de néphrologie à l'hôpital régional d'Oujda de l'oriental Marocain. Ont été inclus tous les patients hospitalisés en néphrologie avec une infection urinaire documentée. Nous avons analysé les données démographiques, cliniques, biologiques, et thérapeutiques de nos patients à l'admission et au cours de leurs hospitalisations. 48 épisodes d'infections urinaires chez 43 patients ont été colligés dont 3 enfants. L'incidence de l'infection urinaire dans notre étude était de 4,65%. La médiane d’âge était de 53 (32-66) années. 60,4% étaient de sexe féminin. Le germe isolé était un Escheria Coli dans 58,3% et un Klebsiella dans 29,2%. Le germe isolé était résistant à l'amoxicilline-acide clavulanique dans 83% des cas. L'antibiotique prescris en premiére intention chez nos patients était une céphalosporine de 3 éme génération dans 50%. L’évolution chez nos patients était favorable dans 89,6% des cas. 33,3% avaient présenté un sepsis et on a noté le décès dans 10,4% des cas. Les infections urinaires chez l'insuffisant rénal chronique reste très grave vu leur lourde morbi-mortalié d'où l'intêrét d'un dépistage précoce chez cette population. Un usage raisonné des antibiotiques est nécessaire afin de prévenir l'extension des résistances bactériennes. PMID:26213601

A stratified random sample of staff working in 14 higher education institutions in England was used. The results showed that, whilst commitment was lower and levels of occupational stress were significantly higher with regard to work relationships, control and resources and communication, compared to the normative data, staff reported significantly lower levels of stress relating to work-life balance, overload, and job dissatisfaction. Compared to normative data, participants reported significantly lower levels of physical ill-health and psychological outcomes of stress. The results support previous findings identifying a protective effect of job satisfaction against the negative consequences of workplace stress. Opsomming Terwyl dit nie ontken word dat die vlak van werkstres van personeel wat in universiteite en kolleges werk, verhoog nie, ervaar akademiese personeel steeds tevredenheid met hul werk. ’n Gestratifiseerde ewekansige steekproef van personeel wat by 14 hoër opvoedkundige instellings in Engeland werk, is geneem. Die resultate het aangetoon dat hoewel verbondenheid laer en werkstres beduidend hoër was ten opsigte van werksverhoudinge, kontrole en bronne en kommunikasie vergeleke met normatiewe data, personeel beduidend laer vlakke van stres ten opsigte van werklewe balans, oorlading en werkstevredenheid getoon het. Deelnemers het ook beduidend laer vlakke van fisieke ongesondheid en psigologiese uitkomstes van stres gerapporteer. Die resultate ondersteun vorige bevindings wat ’n beskermende effek van werkstevredenheid teen die negatiewe uitkomstes van stres identifiseer.

Software packages for spatial data often implement a hybrid approach of interpreted and compiled programming languages. The compiled parts are usually written in C, C++, or Fortran, and are efficient in terms of computational speed and memory usage. Conversely, the interpreted part serves as a convenient user-interface and calls the compiled code for computationally demanding operations. The price paid for the user friendliness of the interpreted component is-besides performance-the limited access to low level and optimized code. An example of such a restriction is the 64-bit vector support of the widely used statistical language R. On the R side, users do not need to change existing code and may not even notice the extension. On the other hand, interfacing 64-bit compiled code efficiently is challenging. Since many R packages for spatial data could benefit from 64-bit vectors, we investigate strategies to efficiently pass 64-bit vectors to compiled languages. More precisely, we show how to simply extend existing R packages using the foreign function interface to seamlessly support 64-bit vectors. This extension is shown with the sparse matrix algebra R package spam. The new capabilities are illustrated with an example of GIMMS NDVI3g data featuring a parametric modeling approach for a non-stationary covariance matrix.

LISP software generative compilation within the frame of a SLIP system; La compilation generative de programmes LISP dans le cadre d'un systeme SLIP

Sitbon, Andre

1968-04-24

After having outlined the limitations associated with the use of some programming languages (Fortran, Algol, assembler, and so on), and the interest of the use of the LISP structure and its associated language, the author notices that some problems remain regarding the memorisation of the computing process obtained by interpretation. Thus, he introduces a generative compiler which produces an executable programme, and which is written in a language very close to the used machine language, i.e. the FAP assembler language.

The US Nuclear Regulatory Commission has initiated the Fuel Cycle Risk Assessment Program to provide risk assessment methods for assistance in the regulatory process for nuclear fuel cycle facilities other than reactors. Both the once-through cycle and plutonium recycle are being considered. A previous report generated by this program defines and describes fuel cycle facilities, or elements, considered in the program. This report, the second from the program, describes the survey and computer compilation of fuel cycle risk-related literature. Sources of available information on the design, safety, and risk associated with the defined set of fuel cycle elements were searched and documents obtained were catalogued and characterized with respect to fuel cycle elements and specific risk/safety information. Both US and foreign surveys were conducted. Battelle's computer-based BASIS information management system was used to facilitate the establishment of the literature compilation. A complete listing of the literature compilation and several useful indexes are included. Future updates of the literature compilation will be published periodically. 760 annotated citations are included.

Run-Time and Compiler Support for Programming in Adaptive Parallel Environments

Guy Edjlali

Full Text Available For better utilization of computing resources, it is important to consider parallel programming environments in which the number of available processors varies at run-time. In this article, we discuss run-time support for data-parallel programming in such an adaptive environment. Executing programs in an adaptive environment requires redistributing data when the number of processors changes, and also requires determining new loop bounds and communication patterns for the new set of processors. We have developed a run-time library to provide this support. We discuss how the run-time library can be used by compilers of high-performance Fortran (HPF-like languages to generate code for an adaptive environment. We present performance results for a Navier-Stokes solver and a multigrid template run on a network of workstations and an IBM SP-2. Our experiments show that if the number of processors is not varied frequently, the cost of data redistribution is not significant compared to the time required for the actual computation. Overall, our work establishes the feasibility of compiling HPF for a network of nondedicated workstations, which are likely to be an important resource for parallel programming in the future.

1994-12-01

The document contains a compilation of all available scientific and technical data on the irradiation of strawberries. It is intended to assist governments in considering the authorization of this particular application of radiation processing of food and in ensuring its control in the facility and the control of irradiated food products moving in trade. The compilation was prepared in response to the requirement of the Codex General Standard for Irradiated Foods and associated Code that radiation treatment of food be justified on the basis of a technological need or of a need to improve the hygienic quality of food. It was prepared also in response to the recommendations of the FAO/IAEA/WHO/ITC-UNCTAD/GATT International conference on the Acceptance, Control of and Trade in Irradiated Food (Geneva, 1989) concerning the need for regulatory control of radiation processing of food.
