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.

Porting OMTTs to CORBA

Jörg Kienzle

The Common Object Request Broker Architecture standardizes a platform- and programming-language-independent distributed object com-puting environment. It also provides a standard for several distributed servic-es. The Object Transaction Service provides an ...

On the Weakest Failure Detector for Non-Blocking Atomic Commit.

Rachid Guerraoui

This paper addresses the question of the weakest failure detector to solve the Non-Blocking Atomic Commit (NBAC) problem in an asynchronous system. We define the set A of timeless failure detectors which excludes detectors that provide information about gl ...

Using Optimistic Atomic Broadcast in Transaction Processing Systems

André Schiper, Matthias Wiesmann, Fernando Pedone

Atomic broadcast primitives are often proposed as a mechanism to allow fault-tolerant cooperation between sites in a distributed system. Unfortunately, the delay incurred before a message can be delivered makes it difficult to implement high performance, s ...

On the Hardness of Failure-Sensitive Agreement Problems

Rachid Guerraoui

In [CT96], [FRT99], and [SM95], respectively, it was stated that the weakest failure detector for any of non-blocking atomic commit, terminating reliable broadcast and leader election, is the Perfect failure detector P. This paper presents a counter exampl ...

The database state machine and group communication issues

Fernando Pedone

Distributed computing is reshaping the way people think about and do daily life activities. On-line ticket reservation, electronic commerce, and telebanking are examples of services that would be hardly imaginable without distributed computing. Nevertheles ...

The Database State Machine Approach

Rachid Guerraoui, André Schiper, Fernando Pedone

Database replication protocols have historically been built on top of distributed database systems, and have consequently been designed and implemented using distributed transactional mechanisms, such as atomic commitment. We present the database state mac ...

A Systematic Classification of Replicated Database Protocols based on Atomic Broadcast

André Schiper, Matthias Wiesmann, Fernando Pedone

Database replication protocols based on group communication primitives have recently emerged as a promising technology to improve database fault-tolerance and performance. Roughly speaking, this approach consists in exploiting the order and atomicity prope ...
