I am a permanent CEA computer scientist at Maison de la Simulation where I lead the Science of Computing team. My research focuses on programming models for high-performance computing. I am especially interested in the question of separation of concerns between the simulated domain specific aspects and optimization aspects.

I try to concretize my research into production-level software like the DDC, Deisa, or PDI libraries whose development I started, or Kokkos, a project of the Linux Foundation originating from the US DoE. I also try to apply these libraries in production into real codes like the Gysela code for example.

I lead the CExA project that contributes to the Kokkos ecosystem. I also take part in the NumPEx programme, that intends to contribute to the French Exascale software stack. In this programme, I co-lead the Exa-DoST project about IO and data analysis libraries and tools, in the Exa-DI project, I co-lead the work on software packaging, deployment, and CI/CD, and in the Exa-Soft project, I take part in the work GPU programming models.

Multiple positions are funded and available to work with me:

• join the CExA project as a software engineer,
• join the CExA project as a DevOps engineer,
• multiple PhD are funded in the context of CExA and NumPEx, let me know if you are interested,
• motivated interns are always welcome!
