Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Message passing and shared memory are two techniques parallel programs use for coordination and communication. This paper studies the strengths and weaknesses of these two mechanisms by comparing equivalent, well-written message-passing and shared-memory p ...
We compare the performance of software-supported shared memory on a general-purpose network to hardware-supported shared memory on a dedicated interconnect. Up to eight processors, our results are based on the execution of a set of application programs on ...
The paper discusses implementations of fine-grain memory access control, which selectively restricts reads and writes to cache-block-sized memory regions. Fine-grain access control forms the basis of efficient cache- coherent shared memory. The paper focus ...
\begin{abstract} This paper presents the LWNS a light weight name service specially designed for groupware applications and an example of its use. The chosen application, called {\sc Duplex}, is a collaborative editing environment for users connected throu ...
The paper describes Tempest, a collection of mechanisms for communication and synchronization in parallel programs. With these mechanisms, authors of compilers, libraries, and application programs can exploit-across a wide range of hardware platforms-the b ...
Recent research has offered programmers increased options for programming parallel computers by exposing system policies (e.g., memory coherence protocols) or by providing several programming paradigms (e.g. message passing and shared memory) on the same p ...
Distributed shared memory 8DSM) is an abstraction of shared memory on a distributed memory machine. Hardware DSM systems support this abstraction at the architecture level; software DSM systems support the abstraction within the runtime system. One of the ...
This paper summarizes how distributed shared memory (DSM) can be both efficiently and portably supported by the Tempest interface. Tempest is a collection of mechanisms for communication and synchronization in parallel programs. These mechanisms provide co ...
Unlike compiler-generated message-passing code, the coherence mechanisms in shared-memory systems work equally well for regular and irregular programs. In many programs, however compile-time information about data accesses would permit data to be transferr ...
We describe a parallel implementation of a genetic linkage analysis program that achieves good speedups, even for analyses on a single pedigree and with a single starting recombination fraction vector. Our parallel implementation has been run on three diff ...
