CExA project
CExA projects aims to develop and support the adoption of a Kokkos-based GPU model to Compute at Exascale At CEA and beyond.
Our technical contributions
Support our applications
- Test UVM viability & performance
- Add required solvers to Kokkos-kernels
Test on our hardware & improve kokkos for it
- Intel PVC backend improvement
- Nvidia Grace Hopper memory management handling
Work on specific projects in the Kokkos ecosystem
- DDC: Discrete Domain Computation library
- Kokkos-fft: Performance portable FFT with a Kokkos API
- lead by CExA
- Kokkos Comm: Kokkos-MPI integration
- co-lead by CExA
Improvements to software quality
- Setup GPU CI for CEA libraries
- Maintaining Kokkos Spack recipes
- Huge refactor & redesign for
Kokkos::create_mirror[_view][_and_copy]
Improvement to Kokkos documentation
- Website improvement
- Cheat-sheets creation
Our contributions to dissemination
- Trainings
- First training with Christian Trott & Damien Lebrun september 2023in Saclay
- Second training on June 17-19 2024 @ Saclay with Damien Lebrun & Luc Berger-Vergiat
- Regular online meetings: Informal presentations & discussions about Kokkos, its ecosystem & GPU at large
- CExA virtual café in French, once a month
- Kokkos virtual tea-time in English, once a month
- Kokkos slack now has a #general-fr channel (~10% of the whole community)
