Abstract:

Emerging VLSI/ULSI technologies have created new opportunities in designing computer architectures capable of hiding the latencies and synchronization overheads associated with von Neumann-style multiprocessing. Pure Dataflow architectures have been suggested as solutions, but they do not adequately address the issues of local memory latencies and fine-grain synchronization costs. In this thesis, we propose a novel hybrid dataflow/von Neumann architecture, called the Super-Actor Machine, to address the problems facing von Neumann and pure dataflow machines. This architecture uses a novel high-

Abstract:

The FFT is an efficient algorithm for computing the DFT. It drastically reduces the cost of implementing the DFT on digital computing systems. Nevertheless, the FFT is still computationally intensive, and continued technological advances of computers demand larger and faster implementations of this algorithm. Past attempts at producing high-performance, and small FFT implementations, have focused on custom hardware (ASICs and FPGAs). Ultimately, the most efficient have been single-chipped, streaming I/O, pipelined FFT architectures. These architectures increase computational concurrency throug

Abstract:

Modern devices such as smartphones and smartwatches spend a large amount of their life idle, waiting for external events. During this time, they are expending energy, using up battery life. Increasing power consumption is a rising concern to users and researchers alike. Power gating, turning off a blocks of hardware when idle, reduces static power consumption. The Metal-Oxide-Semiconductor Field-Effect Transistors (MOSFETs) currently employed in processors leak current. Even in power gated circuits, MOSFET power gating may only save between 60-80% of power. A different type of switch, a N

However, due to patchy support and the existence of multiple approaches for Native Multicast, the support for Native Multicast is fragmented into isolated areas termed Multicast Islands. This renders Native Multicast unfit to be used as an Internet wide application.

Modern main memory is primarily built using dynamic random access memory (DRAM) chips. As DRAM chip scales to higher density, there are mainly three problems that impede DRAM scalability and performance improvement. First, DRAM refresh overhead grows from negligible to severe, which limits DRAM scalability and causes performance degradation. Second, although memory capacity has increased dramatically in past decade, memory bandwidth has not kept pace with CPU performance scaling, which has led to the memory wall problem. Third, DRAM dissipates considerable power and has been reported to accoun

Nous nous intéressons dans cette thèse aux grandes architectures parallèles hybrides, c'est-à-dire aux architectures parallèles qui sont une combinaison de processeurs généraliste (Intel Xeon par exemple) et de processeurs accélérateur (GPU Nvidia). L'exploitation efficace de ces grappes hybrides pour le calcul haute performance est au cœur de nos travaux. L'hétérogénéité des ressources de calcul au sein des grappes hybrides pose de nombreuses problématiques lorsque l'on souhaite les exploiter efficacement avec de grandes applications scientifiques existantes. Deux principales problématiques o

Abstract:

Les travaux présentés dans le cadre de cette thèse portent sur l'étude, la conception, le développement et le test d'un système de reconnaissance de mots manuscrits non contraints en-ligne pour une application omni-scripteurs. Le système proposé repose sur une architecture hybride neuro-markovienne comportant d'une part, un réseau de neurones à convolution (TDNN et/ou SDNN), et d'autre part des modèles de Markov à états cachés (MMC). Le réseau de neurones a une vision globale et travaille au niveau caractère, tandis que le MMC s'appuie sur une description plus locale et permet le passage du ca

Abstract:

Les systèmes de calcul actuels sont généralement des grappes de machines composés de nombreux processeurs à l'architecture fortement hiérarchique. Leur exploitation constitue le défi majeur des implémentations de modèles de programmation tels MPI ou OpenMP. Une pratique courante consiste à mélanger ces deux modèles pour bénéficier des avantages de chacun. Cependant ces modèles n'ont pas été pensés pour fonctionner conjointement ce qui pose des problèmes de performances. Les travaux de cette thèse visent à assister le développeur dans la programmation d'application de type hybride. Il s'appuien

Abstract:

Les nouvelles architectures de calcul intensif intègrent de plus en plus de microprocesseurs qui eux-mêmes intègrent un nombre croissant de cœurs de calcul. Cette multiplication des unités de calcul dans les architectures ont fait apparaître des topologies fortement hiérarchiques. Ces architectures sont dites NUMA. Les algorithmes de simulation numérique et les solveurs de systèmes linéaires qui en sont une brique de base doivent s'adapter à ces nouvelles architectures dont les accès mémoire sont dissymétriques. Nous proposons dans cette thèse d'introduire un ordonnancement dynamique adapté au
