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.

Early Deciding Synchronous Renaming in O( logf ) Rounds or Less

Rachid Guerraoui, Dan Alistarh, Hagit Albo Attiya

Renaming is a fundamental problem in distributed computing, in which a set of n processes need to pick unique names from a namespace of limited size. In this paper, we present the first early-deciding upper bounds for synchronous renaming, in which the run ...

Laws of Order: Expensive Synchronization in Concurrent Algorithms Cannot be Eliminated

Rachid Guerraoui, Hagit Albo Attiya

Building correct and efﬁcient concurrent algorithms is known to be a difﬁcult problem of fundamental importance. To achieve ef- ﬁciency, designers try to remove unnecessary and costly synchro- nization. However, not only is this manual trial-and-error proc ...

Structured Derivation of Semi-Synchronous Algorithms

André Schiper, Martin Hutle, Zarko Milosevic, Fatemeh Borran, Hagit Albo Attiya

The semi-synchronous model is an important middle ground between the synchronous and the asynchronous models of distributed computing. In this model, processes can detect (timeout) when other processes fail. However, since detection is done by timing out, ...

COMBINE: An Improved Directory-Based Consistency Protocol

Vincent Gramoli, Hagit Albo Attiya

This paper presents COMBINE, a directory-based consistency protocol for shared objects, designed for large-scale distributed systems with unreliable links. Directory-based consistency protocols support move requests, allowing to write the object locally, a ...

Fast Randomized Test-and-Set and Renaming

Rachid Guerraoui, Seth Gilbert, Dan Alistarh, Hagit Albo Attiya, Andrei Giurgiu

Most people believe that renaming is easy: simply choose a name \emph{at random}; if more than one process selects the same name, then try again. We highlight the issues that occur when trying to implement such a scheme and shed new light on the read-write ...

A Provably Starvation-Free Distributed Directory Protocol

Vincent Gramoli, Hagit Albo Attiya

This paper presents Combine, a distributed directory protocol for shared objects, designed for large-scale distributed systems. Directory protocols support move requests, allowing to write the object locally, as well as lookup requests, providing a read-on ...

The Complexity of Obstruction-Free Implementations

Rachid Guerraoui, Hagit Albo Attiya

Obstruction-free implementations of concurrent ob jects are optimized for the common case where there is no step contention, and were recently advocated as a solution to the costs associated with synchronization without locks. In this paper, we study this ...

Partial Snapshot Objects

Rachid Guerraoui, Eric Ruppert, Hagit Albo Attiya

We introduce a generalization of the atomic snapshot object, which we call the partial snapshot object. This object stores a vector of values. Processes may write components of the vector individually or atomically scan any subset of the components. We inv ...
