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.

Dynamic Byzantine Reliable Broadcast

Rachid Guerraoui, Jovan Komatovic, Dragos-Adrian Seredinschi, Andrei Tonkikh

Reliable broadcast is a communication primitive guaranteeing, intuitively, that all processes in a distributed system deliver the same set of messages. The reason why this primitive is appealing is twofold: (i) we can implement it deterministically in a co ...

Optimal Fair Computation

Rachid Guerraoui, Junxiong Wang

A computation scheme among n parties is fair if no party obtains the computation result unless all other n-1 parties obtain the same result. A fair computation scheme is optimistic if n honest parties can obtain the computation result without resorting to ...

Asynchronous Gossip

Rachid Guerraoui, Seth Gilbert

We study the complexity of gossip in an asynchronous, message-passing fault-prone distributed system. We show that an adaptive adversary can significantly hamper the spreading of a rumor, while an oblivious adversary cannot. The algorithmic techniques prop ...

HydEE: Failure Containment without Event Logging for Large Scale Send-Deterministic MPI Applications

Thomas Ropars

High performance computing will probably reach exascale in this decade. At this scale, mean time between failures is expected to be a few hours. Existing fault tolerant protocols for message passing applications will not be efficient anymore since they eit ...

The Complexity Of Early Deciding Set Agreement

Rachid Guerraoui, Bastian Pochon

In the k-set agreement problem, each processor starts with a private input value and eventually decides on an output value. At most k distinct output values may be chosen, and every processor's output value must be one of the proposed values. We consider a ...

How Efficient Can Gossip Be? (On the Cost of Resilient Information Exchange)

Rachid Guerraoui, Seth Gilbert, Dan Alistarh, Morteza Zadimoghaddam

Gossip, also known as epidemic dissemination, is becoming an increasingly popular technique in distributed systems. Yet, it has remained a partially open question: how robust are such protocols? We consider a natural extension of the random phone-call mode ...

How Efficient Can Gossip Be? (On the Cost of Resilient Information Exchange)

Gossip, also known as epidemic dissemination, is becoming an in- creasingly popular technique in distributed systems. Yet, it has remained a partially open question: how robust are such protocols? We consider a natural ex- tension of the random phone-call ...

JErlang: Erlang with Joins

Hubert Plociniczak

ERLANG is an industrially successful functional language that uses the Actor model for concurrency. It supports the message-passing paradigm by providing pattern-matching over received messages. Unfortunately coding synchronisation between multiple process ...

Sharing is Harder than Agreeing

Rachid Guerraoui

One of the most celebrated results of the theory of distributed computing is the impossibility, in an asynchronous system of

n

processes that communicate through shared memory registers, to solve the set agreement problem where the processes need to deci ...

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 ...
