Graph Chatbot

Chattez avec Graph Search

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.

The Alpha of Indulgent Consensus

Rachid Guerraoui

This paper presents a simple framework unifying a family of consensus algorithms that can tolerate process crash failures and asynchronous periods of the network, also called indulgent consensus algorithms. Key to the framework is a new abstraction we intr ...

Spatial Memory Streaming

Anastasia Ailamaki, Babak Falsafi

Prior research indicates that there is much spatial variation in applications' memory access patterns. Modern memory systems, however, use small fixed-size cache blocks and as such cannot exploit the variation. Increasing the block size would not only proh ...

The Weakest Failure Detectors to Boost Obstruction-Freedom

Rachid Guerraoui, Michal Kapalka

This paper determines necessary and sufficient conditions to implement wait-free and non-blocking contention managers in a shared memory system. The necessary conditions hold even when universal objects (like compare-and-swap) or random oracles are availab ...

Can a Helmholtz solver run on a cluster?

Marc Anthony David Habisreutinger, Emmanuel Leriche, Vincent Keller

Our vectorized Helmholtz solver runs at 85% efficiency on a NEC SX-5. The most time-consuming parts have been ported on SMP, NUMA, and cluster architectures. It is shown that an OpenMP version can deliver similar performance when running it on a 16 process ...

Compilation for Delay Impact Minimization in VLIW Embedded Systems

David Atienza Alonso, José Luis Ayala Rodrigo

Tomorrow’s embedded devices need to run high resolution multimedia as well as need to support multistandard wireless systems which require an enormous computational complexity with a very low energy consumption and very high performance constraints. In thi ...

Transactional Memory

James Richard Larus

The advent of multicore processors has renewed interest in the idea of incorporating transactions into the programming model used to write parallel programs. This approach, known as transactional memory, offers an alternative, and hopefully better, way to ...

Store-Ordered Streaming of Shared Memory

Anastasia Ailamaki, Babak Falsafi

Coherence misses in shared-memory multiprocessors account for a substantial fraction of execution time in many important scientific and commercial workloads. Memory streaming provides a promising solution to the coherence miss bottleneck because it improve ...

Temporal Streaming of Shared Memory

Anastasia Ailamaki, Babak Falsafi

Coherent read misses in shared-memory multiprocessors account for a substantial fraction of execution time in many important scientific and commercial workloads. We propose Temporal Streaming, to eliminate coherent read misses by streaming data to a proces ...

What Can Be Implemented Anonymously?

Rachid Guerraoui, Eric Ruppert

Abstract. The vast majority of papers on distributed computing assume that processes are assigned unique identifiers before computation begins. But is this assumption necessary? What if processes do not have unique identifiers or do not wish to divulge the ...
