Hello world ! This is my first blog. I'm Rémi Bourgeois, PhD. I am a researcher/engineer working at the French Atomic Energy Commission (CEA). I work on the TRUST platform, a HPC (multi-GPU) CFD code that serves as a basis for many research/industrial applications.

I like to write about what I do as it forces me to formalize my idea, and because I think it might help others.

My research / engineering interests include:

  • GPU kernel / application optimization.
  • Using / picking GPU-enabled linear algebra libraries wisely.
  • Finite volume methods, MHD convection see my PhD thesis on the subject !
  • Continuous integration (gitlab / github).
  • Communication avoiding algorithms.
  • Experimenting with reduced precision.

The opinions expressed here are only mine, and do not reflect the opinions of CEA. Moreover, I am very prone to errors and quick conclusion. If you spot one, feel free to reach and discuss !
