Projects CHRONOS : A totally ordered timestamping system (http ://chronos.univ-pau.fr). OSA (03/2006 - 10/2006, at INRIA) : Open Simulation Architecture, A Collaborative Platform for Component-Based Discrete-Event Simulation. UsECC (Ubiquitous storage ECC-coding, at INRIA) - A code in Maple for simulating US Storage, an ECC-coding storage system. MASCOPT (06/2005 11/2005, at INRIA) : Mascotte Optimization, a library that provides a set of tools for network optimization problems. Examples of problems are routing, grooming, survivability, or virtual network design.
