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.

Gossiping Capabilities

Rachid Guerraoui, Anne-Marie Kermarrec, Maxime Monod, Davide Frey

Gossip-based protocols are now acknowledged as a sound basis to implement collaborative high-bandwidth content dissemination: content location is disseminated through gossip, the actual contents being subsequently pulled. In this paper, we present HEAP, HE ...

On the Complexity of Asynchronous Gossip

Rachid Guerraoui, Seth Gilbert

In this paper, we study the complexity of gossip in an asynchronous, message-passing fault-prone distributed system. In short, we show that an adaptive adversary can significantly hamper the spreading of a rumor, while an oblivious adversary cannot. In the ...

On Obstruction-Free Transactions

Rachid Guerraoui, Michal Kapalka

This paper studies obstruction-free software transactional memory systems (OFTMs). These systems are appealing, for they combine the atomicity property of transactions with a liveness property that ensures the commitment of every transaction that eventuall ...

Stretching Transactional Memory

Rachid Guerraoui, Michal Kapalka, Aleksandar Dragojevic

Transactional memory (TM) is an appealing abstraction for programming multi-core systems. Potential target applications for TM, such as business software and video games, are likely to involve complex data structures and large transactions, requiring speci ...

Permissiveness in Transactional Memories

Rachid Guerraoui, Vasu Singh

We introduce the notion of permissiveness in transactional memories (TM). Intuitively, a TM is permissive if it never aborts a transaction when it need not. More specifically, a TM is permissive with respect to a safety property

A Scalable and Oblivious Atomicity Assertion

Rachid Guerraoui, Marko Vukolic

This paper presents SOAR: the first oblivious atomicity assertion with polynomial complexity. SOAR enables to check atomicity of a single-writer multi-reader register implementation. The basic idea underlying the low overhead induced by SOAR lies in greedi ...

The Weakest Failure Detector for Message Passing Set-Agreement

Rachid Guerraoui

In the set-agreement problem, n processes seek to agree on at most n−1 different values. This paper determines the weakest failure detector to solve this problem in a message-passing system where processes may fail by crashing. This failure detector, calle ...

How to solve consensus in the smallest window of synchrony

Rachid Guerraoui, Seth Gilbert, Dan Alistarh

This paper addresses the following question: what is the minimum-sized synchronous window needed to solve consensus in an otherwise asynchronous system? In answer to this question, we present the first optimally-resilient algorithm ASAP that solves consens ...
