Abstract

Die ersten Kapitel konzentrieren sich auf die Informatik und beinhalten informatische Grundbegriffe, Rechnerarchitekturen und ein Performancemodell, OpenMP als Programmierumgebung für Mehrkernrechner und MPI und PVM als Programmiermodelle für Rechner mit verteiltem Speicher. Anschließend werden mathematische Algorithmen, Performancebetrachtungen, Design paralleler Programme und Ausführungen zu Simulationsprogrammen aus den Ingenieur- und Naturwissenschaften gegenübergestellt. Die nächsten Kapitel sind Performancebetrachtungen und Parallelisierungsstrategien für mathematische Algorithmen gewidmet, bevor abschließend GPUs behandelt und Teile der zuvor erläuterten Algorithmen auf diese übertragen und diskutiert werden. Roter Faden durch das mit vielen Erläuterungen und Quelltextbeispielen angereicherte Buch ist die Performanceanalyse unterschiedlicher Speicherungstechniken von Feldern am Beispiel der algorithmischen Lösung linearer Gleichungssysteme. Dazu wird zunächst das Gaußsche Eliminationsverfahren auf ein Blockverfahren umgestellt und dieses mit sehr hoher Performance auf einem Mehrkernrechner parallelisiert. Bei der iterativen Lösung linearer Gleichungssysteme steht das konjugierte Gradienten-Verfahren und seine fein granulare Parallelisierung im Vordergrund. Besonderes Augenmerk richtet sich dabei auf die Matrix-Vektor-Multiplikation und die Abhängigkeit der Performance von der Speicherungstechnik der Matrix. Gebietszerlegungsmethoden zur Lösung linearer Gleichungssysteme bieten einen grob granularen Parallelisierungsansatz, der für das massiv parallele Rechnen der fein granularen Parallelisierung auf Schleifenebene überlegen ist.

Abstract

This two volume set LNCS 7016 and LNCS 7017 constitutes the refereed proceedings of the 11th International Conference on Algorithms and Architectures for Parallel Processing, ICA3PP 2011, held in Melbourne, Australia, in October 2011. The first volume presents 24 revised regular papers and 17 revised short papers together with the abstract of the keynote lecture - all carefully reviewed and selected from 85 initial submissions. The papers cover the many dimensions of parallel algorithms and architectures, encompassing fundamental theoretical approaches, practical experimental results, and commercial components and systems and focus on two broad areas of parallel and distributed computing, i.e., architectures, algorithms and networks, and systems and applications.
