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.

Atomic boxes: coordinated exception handling with transactional memory

Vincent Gramoli, Pascal Felber

In concurrent programs raising an exception in one thread does not prevent others from operating on an inconsistent shared state. Instead, exceptions should ideally be handled in coordination by all the threads that are affected by their cause. In this pap ...

Democratizing Transactional Programming

Rachid Guerraoui, Vincent Gramoli

The Transaction abstraction is arguably one of the most appealing middleware paradigms. It lies typically between the programmer of a concurrent or distributed application on the one hand, and the operating system with the underlying network on the other h ...

Transaction Polymorphism

Rachid Guerraoui, Vincent Gramoli

Concurrent implementations of abstract types usually rely on lock-free primitives or locks and are highly tuned to support a finite set of efficient operations. However, it is very hard to extend such types for specific needs by adding new operations. The ...

Émulation de mémoire partagée en environnements distribués dynamiques

Vincent Gramoli

Most distributed systems are large-scale and dynamic. Communication has thus become a critical issue and the shared memory, which is a reliable paradigm of communication, allow distributed nodes to exchange information through read and write operations. In ...

Brief Announcement: Transaction Polymorphism

Rachid Guerraoui, Vincent Gramoli

In this work, we present transaction polymorphism; a synchronization technique that provides more control to the programmer than traditional (i.e., monomorphic) transactions to achieve comparable performance to generic lock-based and lock-free solutions. ...

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 ...

Composing Relaxed Transactions

Rachid Guerraoui, Vincent Gramoli, Mihai Letia

As the classical transactional abstraction is sometimes considered too restrictive in leveraging parallelism, a lot of work has been devoted to devising relaxed transactional models with the goal of improving concurrency. Nevertheless, the quest for improv ...

The VELOX Transactional Memory Stack

Rachid Guerraoui, Vincent Gramoli, Michal Kapalka, Aleksandar Dragojevic, Pascal Felber

The adoption of multi- and many-core architectures for mainstream computing undoubtedly brings profound changes in the way software is developed. In particular, the use of fine grained locking as the multi-core programmer’s coordination methodology is cons ...

On the Input Acceptance of Transactional Memory

Vincent Gramoli, Pascal Felber

We present the Input Acceptance of Transactional Memory (TM). Despite the large interest for performance of TMs, no existing research work has investigated the impact of solving a conflict that does not need to be solved. Traditional solutions for a TM to ...

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 ...
