Available in PDF, EPUB and Kindle. Book excerpt: Dans cette thèse, nous nous intéressons à l'adaptation de l'algorithmique aux architectures parallèles. Les plateformes hautes performances actuelles disposent de plusieurs niveaux de parallélisme et requièrent un travail considérable pour en tirer parti. Les superordinateurs possèdent de plus en plus d'unités de calcul et sont de plus en plus hétérogènes et hiérarchiques, ce qui complexifie d'autant plus leur utilisation.Nous nous sommes intéressés ici à plusieurs aspects permettant de tirer parti des architectures parallèles modernes. Tout au long de cette thèse, plusieurs problèmes de natures différentes sont abordés, de manière plus théorique ou plus pratique selon le cadre et l'échelle des plateformes parallèles envisagées.Nous avons travaillé sur la modélisation de problèmes dans le but d'adapter leur formulation à des solveurs existants ou des méthodes de résolution existantes, en particulier dans le cadre du problème de la factorisation en nombres premiers modélisé et résolu à l'aide d'outils de programmation linéaire en nombres entiers.La contribution la plus importante de cette thèse correspond à la conception d'algorithmes pensés dès le départ pour être performants sur les architectures modernes (processeurs multi-coeurs, Cell, GPU). Deux algorithmes pour résoudre le problème du compressive sensing ont été conçus dans ce cadre : le premier repose sur la programmation linéaire et permet d'obtenir une solution exacte, alors que le second utilise des méthodes de programmation convexe et permet d'obtenir une solution approchée.Nous avons aussi utilisé une bibliothèque de parallélisation de haut niveau utilisant le modèle BSP dans le cadre de la vérification de modèles pour implémenter de manière parallèle un algorithme existant. A partir d'une unique implémentation, cet outil rend possible l'utilisation de l'algorithme sur des plateformes disposant de différents niveaux de parallélisme, tout en ayant des performances de premier ordre sur chacune d'entre elles. En l'occurrence, la plateforme de plus grande échelle considérée ici est le cluster de machines multiprocesseurs multi-coeurs. De plus, dans le cadre très particulier du processeur Cell, une implémentation a été réécrite à partir de zéro pour tirer parti de celle-ci.

This book was released on 2008-05-31 with total page 496 pages. Available in PDF, EPUB and Kindle. Book excerpt: Multi-objective optimization (MO) is a fast-developing field in computational intelligence research. Giving decision makers more options to choose from using some post-analysis preference information, there are a number of competitive MO techniques with an increasingly large number of MO real-world applications. Multi-Objective Optimization in Computational Intelligence: Theory and Practice explores the theoretical, as well as empirical, performance of MOs on a wide range of optimization issues including combinatorial, real-valued, dynamic, and noisy problems. This book provides scholars, academics, and practitioners with a fundamental, comprehensive collection of research on multi-objective optimization techniques, applications, and practices.

Available in PDF, EPUB and Kindle. Book excerpt: The innovative progress in the development oflarge-and small-scale parallel computing systems and their increasing availability have caused a sharp rise in interest in the scientific principles that underlie parallel computation and parallel programming. The biannual "Parallel Architectures and Languages Europe" (PARLE) conferences aim at presenting current research material on all aspects of the theory, design, and application of parallel computing systems and parallel processing. At the same time, the goal of the PARLE conferences is to provide a forum for researchers and practitioners to ex change ideas on recent developments and trends in the field of parallel com puting and parallel programming. The first ~wo conferences, PARLE '87 and PARLE '89, have succeeded in meeting this goal and made PARLE a conference that is recognized worldwide in the field of parallel computation. PARLE '91 again offers a wealth of high-quality research material for the benefit of the scientific community. Compared to its predecessors, the scope of PARLE '91 has been broadened so as to cover the area of parallel algo rithms and complexity, in addition to the central themes of parallel archi tectures and languages. The proceedings of the PARLE '91 conference contain the text of all con tributed papers that were selected for the programme and of the invited papers by leading experts in the field.

Available in PDF, EPUB and Kindle. Book excerpt: Nous avons étudié dans un premier temps quelques problèmes fondamentaux sur les réseaux point à point basés sur les graphes de Cayley. La complexité de certains problèmes de formulation simple n'a pas encore été trouvée pour certaines machines parallèles. Par exemple, on ne connaît pas actuellement la complexité du tri sur un hyper cube. Nous avons présenté divers algorithmes autour de la sélection sur les réseaux hyper cubiques en utilisant les algorithmes de tri les plus rapides actuellement connus. Nous avons aussi défini certaines décompositions des graphes de Cayley qui permettent de décrire des algorithmes de communication générale simples et efficaces, comme la diffusion et le commérage pour le star-graph. Dans un second temps, nous avons étudié les réseaux basés sur des interconnexions optiques. Le problème des machines parallèles de réseau d'interconnexion point -à -point provient de la faiblesse des communications générales qui sont souvent sollicitées dans la plupart des programmes scientifiques actuels. Les interconnexions optiques permettent de créer des réseaux plus denses avec des débits plus importants que les technologies classiques. Dans ce type de réseau, nous avons reconsidéré diverses problématiques du parallélisme. Nous avons regardé le comportement de quelques opérations de communication générale, comme la diffusion. Nous avons d'autre part donné les propriétés d'extensibilité de ces réseaux

Download or read book Algorithms written by Sanjoy Dasgupta and published by McGraw-Hill Higher Education. This book was released on 2006 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text, extensively class-tested over a decade at UC Berkeley and UC San Diego, explains the fundamentals of algorithms in a story line that makes the material enjoyable and easy to digest. Emphasis is placed on understanding the crisp mathematical idea behind each algorithm, in a manner that is intuitive and rigorous without being unduly formal. Features include:The use of boxes to strengthen the narrative: pieces that provide historical context, descriptions of how the algorithms are used in practice, and excursions for the mathematically sophisticated. Carefully chosen advanced topics that can be skipped in a standard one-semester course but can be covered in an advanced algorithms course or in a more leisurely two-semester sequence.An accessible treatment of linear programming introduces students to one of the greatest achievements in algorithms. An optional chapter on the quantum algorithm for factoring provides a unique peephole into this exciting topic. In addition to the text DasGupta also offers a Solutions Manual which is available on the Online Learning Center."Algorithms is an outstanding undergraduate text equally informed by the historical roots and contemporary applications of its subject. Like a captivating novel it is a joy to read." Tim Roughgarden Stanford University
