Download or read book Environnement de programmation parall le adapt au traitement d images et au calcul scientifique written by Abdelkrim Fatni and published by . This book was released on 1998 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les applications " Grand Challenge " nécessitent une puissance de calcul très importante. Malgré la haute performance des outils informatiques engendrée par la haute intégration des circuits électroniques, la puissance requise par ces applications, de l'ordre du tera-flops, reste non satisfaite. Le challenge pose a l'informaticien trouve sa solution dans la parallélisation de l'environnement de calcul. Celui-ci est constitué du calculateur, de l'algorithmique, du langage de programmation et de son compilateur. Mais l'environnement ne peut être efficace que s'il y a adéquation entre ces différentes composantes. Dans ce but, un environnement de programmation parallèle adapte au traitement d'images et au calcul scientifique est proposé dans cette thèse. Dans cette étude nous avons introduit le langage C// et son compilateur. Le langage C// est une extension parallèle du C basée sur le modèle de programmation a parallélisme de données. Le modèle d'exécution est de type SPMD à mémoire partagée et physiquement distribuée (DSM). Plusieurs processeurs de la machine exécutent le même programme et communiquent à travers des variables partagées. Des points de synchronisation sont utilisés par le programmeur pour coordonner les divers flots de la machine et maintenir la cohérence de données. L'atelier de compilation de C // se compose de deux phases consécutives. La première phase consiste en la traduction du code C // en code C après analyse syntaxique et sémantique des constructions parallèles relevant de notre paradigme de programmation. Ce code sera ensuite compilé par le compilateur Gcc de la FSF (Free Software Foundation) en code machine. L'utilité de Gcc provient de sa disponibilité, sa portabilité et sa configurabilité pour d'autres plates-formes. La machine symphonie nous a servi d'exemple pour la configuration de Gcc. Nous avons aussi implanté l'atelier de compilation sur la machine GFLOPS. Plusieurs applications relevant du domaine de traitement d'images ont été développées et simulées sur GFLOPS. Ceci nous a permis d'évaluer et de valider notre environnement de programmation C // sur cette machine. Les premiers résultats sont très encourageants.

This book was released on 2007-07-07 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers up a deep understanding of concepts and practices behind the composition of heterogeneous components. After the analysis of existing computation and execution models used for the specification and validation of different sub-systems, the book introduces a systematic approach to build an execution model for systems composed of heterogeneous components. Mixed continuous/discrete and hardware/software systems are used to illustrate these concepts. The benefit of reading this book is to arrive at a clear vision of the theory and practice of specification and validation of complex modern systems. Numerous examples give designers highly applicable solutions.

Available in PDF, EPUB and Kindle. Book excerpt: This comprehensive volume offers readers a progressive and highly detailed introduction to the complex behavior of neutrons in general, and in the context of nuclear power generation. A compendium and handbook for nuclear engineers, a source of teaching material for academic lecturers as well as a graduate text for advanced students and other non-experts wishing to enter this field, it is based on the author’s teaching and research experience and his recognized expertise in nuclear safety. After recapping a number of points in nuclear physics, placing the theoretical notions in their historical context, the book successively reveals the latest quantitative theories concerning: • The slowing-down of neutrons in matter • The charged particles and electromagnetic rays • The calculation scheme, especially the simplification hypothesis • The concept of criticality based on chain reactions • The theory of homogeneous and heterogeneous reactors • The problem of self-shielding • The theory of the nuclear reflector, a subject largely ignored in literature • The computational methods in transport and diffusion theories Complemented by more than 400 bibliographical references, some of which are commented and annotated, and augmented by an appendix on the history of reactor physics at EDF (Electricité De France), this book is the most comprehensive and up-to-date introduction to and reference resource in neutronics and reactor theory.
