PhD thesis, 3rd year, "Management of structured data on a grid infrastructure in a peer-to-peer environment"

My main research interest is on convergence of grid and peer-to-peer systems, and is illustrated through the JuxMem platform, which stands for Juxtaposed Memory. JuxMem is a data sharing service for grid computing and is designed as a compromise between DSM systems (for transparency and consistency guarantees) and P2P systems (for scalability and high dynamicity). JuxMem offers the illusion of an unique memory storage area across several clusters, users can store/access data following a standard API for process memory management. Moreover, JuxMem provides consistency guarantees for data through various consistency models and protocols as well as fault tolerance. JuxMem relies on the JXTA P2P framework for its discovery and communication mechanisms. Experimental evaluations and validations on the French Grid'5000 testbed via applications based on the DIET (GridRPC system) and OpenCCM (component model) middlewares have been performed.

There is a University Spotlight on the web site of JXTA about JuxMem. There is also a Developer Spotlight on the web site of JXTA about my activities related to JXTA.

Involved in several JXTA-based projects: platform (core of the Java binding of JXTA, committer), jxta-c (core of the C binding of JXTA, committer), JXTANetMap (visual network utility for JXTA networks, committer).  I'm also one of the project owner of JDF (for JXTA Distributed Framework). JDF is a tool allowing to easily test large-scale JXTA-based P2P systems from a single node.

Short Biography

I received my engineering degree from the Institut National des Sciences Appliquées (INSA) of Rennes (France) in 2003 and my master degree at IFSIC, University of Rennes I, the same year. I am currently a PhD student at IRISA, University of Rennes I.
