In message-passing parallel applications, messages are not delivered in a strict order. The number of messages, their content and their destination may depend on the ordering of their delivery. Nevertheless, for most applications, the computation results s ...
Stream processing has a long history as a way of describing and implementing specific kinds of computational processes. So far, however, it has largely remained an exotic field of endeavor, with relatively small momentum compared to traditional von Neumann c ...
The parallelized model is first presented and a scalability study is achieved. For computational time saving and memory requirement reasons, the implementation of a three dimensional SPH code implies the need for its parallelization, in order to make possi ...
Instruction-grain program monitoring tools, which check and analyze executing programs at the granularity of individual instructions, are invaluable for quickly detecting bugs and security attacks and then limiting their damage (via containment and/or reco ...
There is a rapid rise of multi-cores in recent hardware architectures. To exploit computational power of multi-core architectures, software should shift to be as concurrent as possible; and therefore should have concurrency control mechanisms. There are di ...
This thesis describes our research results in the context of peer-to-peer information retrieval (P2P-IR). One goal in P2P-IR is to build a search engine for the World Wide Web (WWW) that runs on up to hundreds of thousands or even millions computers distri ...
Transactional memory (TM) is a promising paradigm for concurrent programming. Whereas the number of TM implementations is growing, however, little research has been conducted to precisely define TM semantics, especially their progress guarantees. This pape ...
Biotechnology is an area of great innovations that promises to have deep impact on everyday life thanks to profound changes in biology, medicine, and health care. This article will span from the description of the biochemical principles of molecular biolog ...
Transactional memory (TM) is a promising paradigm for concurrent programming. This paper is an overview of our recent work on defining a theory of TM. We first present a correctness condition of a TM, ensured by most existing TM implementations. Then, we d ...
We study erasure-coded atomic register implementations in an asynchronous crash-recovery model. Erasure coding provides a cheap and space-efficient way to tolerate failures in a distributed system. This paper presents ORCAS, Optimistic eRasure-Coded Atomic ...
