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.

Reconfigurable Distributed Storage for Dynamic Networks

Vincent Gramoli, Seth Gilbert

This paper presents a new algorithm for implementing a reconfigurable distributed shared memory in an asynchronous dynamic network. The algorithm guarantees atomic consistency (linearizability) in all executions in the presence of arbitrary crash failures ...

On the Correctness of Transactional Memory

Rachid Guerraoui, Michal Kapalka

Transactional memory (TM) is perceived as an appealing alternative to critical sections for general purpose concurrent programming. Despite the large amount of recent work on TM implementations, however, very little effort has been devoted to precisely def ...

Deferred-update database replication

Rodrigo Malta Schmidt

This thesis is about the design of high-performance fault-tolerant computer systems. More specifically, it focuses on how to develop database systems that behave correctly and with good performance even in the event of failures. Both performance and depend ...

A Formal Analysis of the Deferred Update Technique

Rodrigo Malta Schmidt, Fernando Pedone

The deferred update technique is a widely used approach for building replicated database systems. Its fame stems from the fact that read-only transactions can execute locally to any single database replica, providing good performance for workloads where tr ...

Tashkent: Uniting Durability with Transaction Ordering for High-Performance Scalable Database Replication

Sameh Mohamed Elnikety, Fernando Pedone

In stand-alone databases, the functions of ordering the transaction commits and making the effects of transactions durable are performed in one single action, namely the writing of the commit record to disk. For efficiency many of these writes are grouped ...

A Primary-Backup Protocol for In-Memory Database Replication

Rodrigo Malta Schmidt, Fernando Pedone

The paper presents a primary-backup protocol to manage replicated in-memory database systems (IMDBs). The protocol exploits two features of IMDBs: coarse-grain concurrency control and deferred disk writes. Primary crashes are quickly detected by backups an ...

Lucky Read/Write Access to Robust Atomic Storage

Rachid Guerraoui, Marko Vukolic, Ron Levy

This paper establishes tight bounds on the \emph{best-case} time-complexity of distributed atomic read/write storage implementations that tolerate \emph{worst-case} conditions. We study asynchronous robust implementations where a writer and a set of reader ...

Consistent Main-Memory Database Federations under Deferred Disk Writes

Rodrigo Malta Schmidt, Fernando Pedone

Current cluster architectures provide the ideal environment to run federations of main-memory database systems (FMMDBs). In FMMDBs, data resides in the main memory of the federation servers, significantly improving performance by avoiding I/O during the ex ...
