Sharing Data and Work Across Concurrent Analytical Queries
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.
Software transactional memory (STM) offers a disciplined concurrent programming model for exploiting the parallelism of modern processor architectures. This paper presents the first \emph{deterministic} specification automata for strict serializability and ...
In practice, concurrent programming systems based on message passing are often instantiations of the actor model. A popular implementation of this form of concurrency is the Erlang programming language. Erlang supports massively concurrent systems such as ...
Software transactional memory (STM) is a promising technique for writing concurrent programs. So far, most STM approaches have been experimentally evaluated with small-scale microbenchmarks. In this paper, we present several surprising results from impleme ...
Software transactional memory (STM) is a promising technique for controlling concurrency in modern multi-processor architectures. STM aims to be more scalable than explicit coarse-grained locking and easier to use than fine-grained locking. However, STM im ...

Query processing in traditional Database Management Systems (DBMS) has been extensively studied in the literature and adopted in industry. Such success is, in part, due to the performance of their Query Execution En-gines (QEE) for supporting the execution ...
Superscalar out-of-order microarchitectures can be modified to support redundant execution of a program as two concurrent threads for soft-error detection. However, the extra workload from redundant execution incurs a performance penalty due to increased c ...
A common requirement of many scienti c applications is the ability to process queries involving expensive predicates corresponding to user programs. Optimizing such queries is hard because static cost predictions and statistical estimates are not applicabl ...
In this paper we address the problem of encoding complex concurrency control in reconfigurable systems. Such systems can be often reconfigured, either statically, or dynamically, in order to adapt to new requirements and a changing environment. We therefor ...
We address programming abstractions for building protocols from smaller, reusable microprotocols. The existing protocol frameworks, such as Appia and Cactus, either restrict the amount of concurrency between microprotocols, or depend on the programmer, who ...
