  Jan 2013 - Jan 2014

  Teaching Assistant (45h):
  Master 1 in Computer Sciences (Versailles Saint Quentin en Yvelines
  University)
  - System programming: Fall 2013 & 2014
  - Parallel programming (POSIX threads, OpenMP): Springs 2013, 2014

• Assistant

  Exascale Computing Research, Versailles — Research
  Jan 2011 - Jan 2015

  Thesis subject: "Improving the Hybrid model MPI+Threads through
  applications, runtimes, and performance tools"
  &#9679 Collaboration with CEA/DAM
  &#9679 Field: High Performance Computing
  &#9679 Programming models: MPI, OpenMP
  Achievements:
  &#9679 Implemented an adaptive tree on the OpenMP runtime, part of
  MPC, in order to lower the overhead of the OpenMP runtime on a
  large spectrum of threads. Obtained a speedup of 4.9x with MPC
  against the Intel Compiler, on 128 OpenMP threads.
  &#9679 Optimized the MPI_Allreduce operation in a parallel manner, by
  using idle OpenMP threads. Gained a speedup of 5.29x on MC, a
  MPI+OpenMP application simulating transport of particles, and
  relying on Monte Carlo methods.
  &#9679 Unified collective operations: Implemented an optimized global
  barrier as a proof of concept, involving MPI tasks and OpenMP
  threads for the same operation. A speedup of 2.45x was gained
  for a configuration with 2 MPI tasks and 64 OpenMP threads on a
  128-core node.
  &#9679 First implementation of OpenMP Tools API (OMPT) in MPC.
  Technical environment: C language, git versioning tool, Linux
