Background

Geoffroy is a scientist with expertise in operating systems, system tools, system libraries, MPI, MPI+X, file system, system profiling.

Over the years, Geoffroy participated to numerous projects from virtualization for HPC, resilience for HPC, HPC runtimes, application profiling and many others. At the moment, his main focus is the execution of MPI+OpenMP applications on leadership platforms, the optimization of scientific simulations for computing platforms offering a deep and complex memory hierarchy, the composition of multi-physics simulations using operating system enclaves, and participate to the MPI standard based on OLCF requirements.
