 | Architectures réparties en Java RMI, CORBA, JMS, sockets, SOAP, services web de Annick Fron Commentaire Ce livre s'adresse aux ingénieurs logiciel, développeurs, architectes et chefs de projet. Il s'adresse aussi aux étudiants en écoles d'ingénieurs et en masters d'informatique. Une architecture logicielle répartie suppose des données différentes et des tâches différentes traitées sur des machines différentes. Il en découle bien évidemment des problèmes de transmissions de données et de synchronisation entre processus. Très longtemps les applications réparties ont été réservées à des applications d'experts (espace, militaire), mais à présent les besoins se diversifient (communication en pair à pair, multiplication des réseaux). Le langage Java qui est né avec les applications en réseau apporte une simplification importante qui met cette technologie à la portée de tous, notamment dans le monde industriel. Le but de cet ouvrage est de donner les clés qui permettront de définir la solution la mieux adaptée à chaque situation rencontrée. Il commence par une explication des concepts de base des architectures réparties en Java. Il tente ensuite d'extraire la substantifique moelle sur la meilleure manière de faire communiquer deux machines entre elles. Enfin, il donne une vue d'ensemble des solutions techniques actuellement disponibles. |

 | Peer-to-peer Computing Building Supercomputers with Web Technologies de Alfred Wai-Sing Loo Commentaire Client/Server architecture was first proposed in the late 1980s as an alternative to conventional mainframe systems. Mainframe processing quickly becomes a bottleneck in any information system, but client/server models shift the processing burden to the client computer. Through workload sharing, client/server systems can improve overall efficiency while reducing budgets. Companies are again searching for ways to improve their processing power without further investment in new hardware and software. Many client computers are idle most of the time, and have unused disk space. The next logical step is to maximise the resources of these computers, and the peer-to-peer (P2P) model is the answer. A new and simple peer-to-peer model will be introduced in this book. In it: Readers will be taught to install peer-to-peer systems which can then manage and distribute the processing power of any number of clients. The size of network can range from two to over a million computers. The software necessary to implement peer-to-peer systems quickly can be downloaded from the book's website. The deployment of web technologies will enable individuals and organisations of all sizes to use computers across a network as though it were a single supercomputer to solve complex problems, and after reading this book, readers will be able to install a peer-to-peer system of any size. |

 | Simulation à événements discrets Modèles déterministes et stochastiques - Exemples d'applications implémentés en Delphi et en C++ de Gérard Fleury, Philippe Lacomme et Alain Tanguy Commentaire Les techniques de simulation permettent de prédire le comportement de systèmes complexes en phase de conception (dimensionnement d'une chaîne de production, par exemple) ou d'optimiser les performances de systèmes existants, qu'il s'agisse de stockage, de transport, de services ou de procédés industriels. S'initier aux techniques de simulation par l'exemple Cet ouvrage introduit les techniques de simulation à événements discrets à travers des exemples de complexité croissante, en évitant autant que possible les exposés théoriques à priori. Il montre d'abord comment réaliser des modèles de simulation déterministes, avant d'aborder la prise en compte du hasard (modèles stochastiques). Un chapitre est dédié au couplage entre simulation et méthodes d'optimisation (recuit simulé et algorithmes génétiques). Le livre s'achève sur une autre technique, celle des automates cellulaires, appliquée à la simulation de la propagation de feux de forêt. Une véritable boîte à outils logicielle fournie sur le CD-Rom d'accompagnement Tous les exemples du livre sont implémentés sous forme de programmes Windows à l'interface graphique soignée, que vous trouverez sur le CD-Rom d'accompagnement. Ces programmes, dont le code source est fourni en Delphi et pour certains en C++, vous aideront à vous familiariser avec la réalisation de modèles de simulation. Vous pourrez également les adapter facilement à vos propres besoins grâce à leur structure modulaire (structures de données et bibliothèque d'objets réutilisables). |

 | Scientific Parallel Computing de L. Ridgway Scott , Terry Clark et Babak Bagheri Commentaire What does Google's management of billions of Web pages have in common with analysis of a genome with billions of nucleotides? Both apply methods that coordinate many processors to accomplish a single task. From mining genomes to the World Wide Web, from modeling financial markets to global weather patterns, parallel computing enables computations that would otherwise be impractical if not impossible with sequential approaches alone. Its fundamental role as an enabler of simulations and data analysis continues an advance in a wide range of application areas. Scientific Parallel Computing is the first textbook to integrate all the fundamentals of parallel computing in a single volume while also providing a basis for a deeper understanding of the subject. Designed for graduate and advanced undergraduate courses in the sciences and in engineering, computer science, and mathematics, it focuses on the three key areas of algorithms, architecture, languages, and their crucial synthesis in performance. The book's computational examples, whose math prerequisites are not beyond the level of advanced calculus, derive from a breadth of topics in scientific and engineering simulation and data analysis. The programming exercises presented early in the book are designed to bring students up to speed quickly, while the book later develops projects challenging enough to guide students toward research questions in the field. The new paradigm of cluster computing is fully addressed. A supporting web site provides access to all the codes and software mentioned in the book, and offers topical information on popular parallel computing systems. Integrates all the fundamentals of parallel computing essential for today's high-performance requirements Ideal for graduate and advanced undergraduate students in the sciences and in engineering, computer science, and mathematics Extensive programming and theoretical exercises enable students to write parallel codes quickly More challenging projects later in the book introduce research questions New paradigm of cluster computing fully addressed Supporting web site provides access to all the codes and software mentioned in the book |

 | Super-Recursive Algorithms de Mark Burgin Commentaire The main achievement of the theory of computations is the elaboration of an exact mathematical model of an algorithm done less than seventy years ago by introducing recursive and partial recursive functions, Turing machines, and Post formal systems. The famous Church-Turing Thesis claims that these models (called recursive algorithms) are the most general. The reason of this is that all mathematical models of algorithms that appeared later were either equivalent or even weaker than Turing machines (or equivalently, partial recursive functions). Theory of super-recursive algorithms refutes this Thesis because computing power of super-recursive algorithms is much greater than that of the conventional, or recursive, algorithms. Consequently, the discovery of super-recursive algorithms provides for a new understanding of some important mathematical results including the famous Gödel incompleteness theorem. In 'Super-Recursive Algorithms,' fundamentals of the theory of super-recursive algorithms will be explained. It will be demonstrated that while recursive algorithms gave a correct theoretical representation of computers at the beginning of the 'computer era', super-recursive algorithms are more adequate as mathematical models for modern computers. In addition to this, super-recursive algorithms provide for a better theoretical frame for computing methods in various areas: for numerical analysis, for search and other operations with huge data arrays, for control and monitoring systems, etc. In the lecture, emphasize will be given to applications related to search in huge and, especially, in dynamic data arrays. |

 | High performance Linux clusters with OSCAR, Rocks, OpenMosix, and MPI de Joseph D. Sloan Commentaire To the outside world, a "supercomputer" appears to be a single system. In fact, it's a cluster of computers that share a local area network and have the ability to work together on a single problem as a team. Many businesses used to consider supercomputing beyond the reach of their budgets, but new Linux applications have made high-performance clusters more affordable than ever. These days, the promise of low-cost supercomputing is one of the main reasons many businesses choose Linux over other operating systems. This new guide covers everything a newcomer to clustering will need to plan, build, and deploy a high-performance Linux cluster. The book focuses on clustering for high-performance computation, although much of its information also applies to clustering for high-availability (failover and disaster recovery). The book discusses the key tools you'll need to get started, including good practices to use while exploring the tools and growing a system. You'll learn about planning, hardware choices, bulk installation of Linux on multiple systems, and other basic considerations. Then, you'll learn about software options that can save you hours--or even weeks--of deployment time. Since a wide variety of options exist in each area of clustering software, the author discusses the pros and cons of the major free software projects and chooses those that are most likely to be helpful to new cluster administrators and programmers. A few of the projects introduced in the book include: MPI, the most popular programming library for clusters. This book offers simple but realistic introductory examples along with some pointers for advanced use. OSCAR and Rocks, two comprehensive installation and administrative systems openMosix (a convenient tool for distributing jobs), Linux kernel extensions that migrate processes transparently for load balancing PVFS, one of the parallel filesystems that make clustering I/O easier C3, a set of commands for administering multiple systems Ganglia, OpenPBS, and cloning tools (Kickstart, SIS and G4U) are also covered. The book looks at cluster installation packages (OSCAR & Rocks) and then considers the core packages individually for greater depth or for folks wishing to do a custom installation. Guidelines for debugging, profiling, performance tuning, and managing jobs from multiple users round out this immensely useful book. . |

 | Patterns for parallel programming de Timothy G. Mattson , Beverly A. Sanders et Berna L. Massingill Commentaire This book uses a patterns approach to help software engineers master the challenges of writing software to run on parallel computers. Parallel computing is not a new term, but increased desktop processor power and the advent of grid computing have brought it into greater attention recently Helps IT departments better leverage company resources A catalog of proven solutions to recurring problems faced by parallel programmers This is a book to help software engineers become parallel programmers. While the demand for parallel software is large and growing, accomplished parallel programmers are in short supply. This new book helps seasoned software practitioners make the transition to this highly specialized discipline of programming. The authors employ a design patterns approach, providing proven solutions to recurring challenges faced by parallel programmers. The result is a highly-practical treatment of the topic that will help software engineers increase their skillset, and ultimately learn to "think" parallel. . |

 | Analyse d'écoulements fluides à partir de séquences de Thomas Corpetti Commentaire Cet ouvrage présente deux méthodes pour analyser les écoulements fluides à partir de séquences d'images par ordinateur. Il traite d'abord du problème de l'estimation du mouvement par la vision sur ordinateur. Il propose ensuite un estimateur de mouvement spécialement conçu pour les phénomènes dynamiques de nature fluide. Dans ce contexte, l'utilisation de techniques standard, originalement conçues pour des mouvements rigides et reposant sur des hypothèses parfois trop simples au regard de la physique des phénomènes étudiés, est délicate. L'estimateur de mouvement proposé intègre des données physiques dans les modèles génériques (équation de continuité et régularisation div-curl en particulier). Ce livre est ensuite consacré à l'analyse d'un champ de déplacement préalablement estimé, relatif à un mouvement fluide. Une méthode visant à extraire les vortex et puits/sources de l'écoulement en s'appuyant sur le modèle de Rankine est proposée. La méthode est fondée sur une représentation analytique du champ des vitesses et permet d'extraire d'autres informations pertinentes relatives à l'écoulement (fonctions de potentiels, décomposition selon Helmholtz de l'écoulement, points singuliers, ...). |
