I am working in the TADaaM Inria team (previously Runtime Inria Team-Project). My primary research interests are:

• Modeling modern hierarchical and multicore platforms;
• I/O in multicore and NUMA hierarchical machines;
• High performance communication;
• Memory management and migration for OpenMP threads scheduling over hierarchical architectures.
