Book Synopsis Distributed Fault-tolerance Techniques for Local Computations by : Brahim Hamid
Download or read book Distributed Fault-tolerance Techniques for Local Computations written by Brahim Hamid and published by . This book was released on 2007 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ce travail constitue une contribution théorique et pratique à l'étude de la tolérance aux pannes dans les système distribués, et de spécifier l'impacte de la théorie des graphes dans ce domaine. Précisément, on s'intéresse aux pannes de processus et nous considérons les pannes transitoires et les pannes franches. Notre but est d'étudier ces systèmes dans le contexte de la localité: Les seuls calculs autorisés sont ceux à base d'informations locales. Ceci revient à capturer la notion de détection et de correction des configurations ``illégales'' qui résultent de l'état arbitraire du systeme. Comme modèle, on utilisera les calculs locaux et à passage de messages. Nos constructions sont basées sur les techniques les plus répondues dans ce domaine: La détection de pannes et l'auto-stabilisation. En combinant ces deux techniques et en gardant la localité comme but ultime, nous construisons un nouvel outil pour transformer un algorithme intolérant en un autre algorithme équivalent mais qui est tolérant aux pannes, dont la preuve de correction est déduite du premier. D'une autre part, nous avons augmenté la plate-forme Visidia pour simuler les pannes. Les pannes transitoires sont simplement simulées à travers des vues permettant de changer l'état des noeuds. Pour les pannes franches, en premier le détecteur de pannes est intégré dans Visidia, en plus d'une interface pour mesurer ses performances pour atteindre les comportements attendus. En second, à travers des vues, l'utilisateur peut stopper le travail d'un noeud et simuler la panne d'un processus. Pour termier cette thèse, nous sollicitons la théorie de graphe pour aider la tolérance aux pannes selon deux aspects. Nous présentons une nouvelle formalisation du test de la connexité de graphes en utilisant la notion de fils de secours. Un algorithme distribué et local pour tester la 2-connexité est proposé dans les deux modèles. Ce résultat nous illumine à propos de la manière dont un pont peut être construit entre ces deux modèles. En second, le calcul des fils de secours est entendu pour étudier la maintenance de forêts d'arbres recouvrants en présence de pannes franches.
Book Synopsis Transforming Computer Technology by : Arthur L. Norberg

Available in PDF, EPUB and Kindle. Book excerpt: Winner of the Association of American Publishers Professional and Scholarly Publishing Award for Computer Science Over the course of several decades, the Pentagon's Information Processing Techniques Office (IPTO) helped transform computing from a cumbersome enterprise based on batch processing to the instantly interactive, graphically rich, highly intelligent computing of today. With the purpose of improving command and control systems for the military, IPTO researchers strengthened time-sharing, laid the groundwork for graphics and parallel processing, contributed to the study of artificial intelligence, and developed the wide-area network that came to be known as the Internet. Transforming Computer Technology examines these and other developments at the Defense Department's Advanced Research Projects Agency in its heyday between 1962 and 1986. The authors show how Pentagon programs affected significant developments in both computer science and engineering. They analyze the management of the office, the origins and growth of important IPTO programs, and the interaction of the staff with the R & D community. They pay special attention to IPTO's role in executing research at the leading edge of computing and networking and in working with the military to transfer that research into practical use. And they show how, by the 1990s, the research results had been assimilated into systems both for the military and for civilian society.

Book Synopsis Where Wizards Stay Up Late by : Matthew Lyon
Download or read book Where Wizards Stay Up Late written by Matthew Lyon and published by Simon and Schuster. This book was released on 1999-08-19 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: Twenty five years ago, it didn't exist. Today, twenty million people worldwide are surfing the Net. Where Wizards Stay Up Late is the exciting story of the pioneers responsible for creating the most talked about, most influential, and most far-reaching communications breakthrough since the invention of the telephone. In the 1960's, when computers where regarded as mere giant calculators, J.C.R. Licklider at MIT saw them as the ultimate communications devices. With Defense Department funds, he and a band of visionary computer whizzes began work on a nationwide, interlocking network of computers. Taking readers behind the scenes, Where Wizards Stay Up Late captures the hard work, genius, and happy accidents of their daring, stunningly successful venture.
