I am working in Raymond Namyst's Runtime INRIA Team-Project.
My research interests include (but are not limited to):

• The MPICH2 project: a high-performance Message Passing Interface Implementation. In particular, I co-designed and implemented the Nemesis Communication subsystem, the defaut communication channel in MPICH2 since release 1.1
• Efficient process placement on multicore and NUMA hierarchical machines, for instance with the knem and hwloc projects.
• Hybrid (eg MPI + OpenMP/threads) programming models for HPC
