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.

Formalizing and verifying transactional memories

Vasu Singh

Transactional memory (TM) has shown potential to simplify the task of writing concurrent programs. TM shifts the burden of managing concurrency from the programmer to the TM algorithm. The correctness of TM algorithms is generally proved manually. The goal ...

Transactions in the Jungle

Rachid Guerraoui, Michal Kapalka, Vasu Singh

Transactional memory (TM) has shown potential to simplify the task of writing concurrent programs. Inspired by classical work on databases, formal definitions of the semantics of TM executions have been proposed. Many of these definitions assumed that acce ...

Transactional memory, linking theory and practice

Vincent Gramoli, Srivatsan Ravi

Transactional memory appears promising for democratizing concurrent programming. Its potential lies in producing code that is extensible as atomicity is preserved under composition of transactions. This new abstraction raises several challenges such as the ...

Fast Access to Distributed Atomic Memory

Rachid Guerraoui, Marko Vukolic, Ron Levy, Partha Dutta

We study eﬃcient and robust implementations of an atomic read-write data structure over an asynchronous distributed message-passing system made of reader and writer processes, as well as a number of servers implementing the data structure. We determine the ...

Extensible Transactional Memory Testbed

Vincent Gramoli, Pascal Felber

Transactional Memory (TM) is a promising abstraction as it hides all synchronization complexities from the programmers of concurrent applications. More particularly the TM paradigm operated a complexity shift from the application programming to the TM prog ...

Efficient System-Enforced Deterministic Parallelism

Bryan Alexander Ford

Deterministic execution offers many benefits for debugging, fault tolerance, and security. Current methods of executing parallel programs deterministically, however, often incur high costs, allow misbehaved software to defeat repeatability, and transform t ...

Theory of Transactional Memory

Michal Kapalka

Transactional memory (TM) is a promising paradigm for concurrent programming, in which threads of an application communicate, and synchronize their actions, via inmemory transactions. Each transaction can perform any number of operations on shared data, an ...

Tight Failure Detection Bounds on Atomic Object Implementations

Rachid Guerraoui

This article determines the weakest failure detectors to implement shared atomic objects in a distributed system with crash-prone processes. We first determine the weakest failure detector for the basic register object. We then use that to determine the we ...

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 ...

Model checking transactional memories

Rachid Guerraoui, Vasu Singh

Model checking transactional memories (TMs) is difficult because of the unbounded number, length, and delay of concurrent transactions, as well as the unbounded size of the memory. We show that, under certain conditions satisfied by most TMs we know of, th ...
