CExA organizes its first international Kokkos tea-time on Wednesday, April the 17th, 2024 for 45min starting at 8AM MT, 10AM EST, 2PM UTC, 4PM CEST. It can be followed on Zoom, by phone, from a visio room or from the Mandelbrot room in the Digiteo Saclay building, France.
Arnaud Durocher will give a talk entitled “Dyablo: A simulation code for astrophysics fluids with adaptive mesh refinement with Kokkos”
Dyablo: A simulation code for astrophysics fluids with adaptive mesh refinement with Kokkos
Arnaud Durocher, Maxime Delorme, CEA-Saclay, IRFU/DEDIP/LILAS
Dyablo is a new code for the simulation of astrophysical plasmas on exascale architectures using Adaptive Mesh Refinement. It is built from the ground up to target new and upcoming Exascale supercomputers with a new codebase in C++ using Kokkos. Dyablo is based on modern software engineering principles to allow “separation of concerns” and collaboration between HPC engineers and physicists through abstract interfaces and modularity. Although Dyablo is still in development, the code is now deployable and usable on all major (French) supercomputers.
We will present Dyablo, how it’s made and what challenges had to be resolved for AMR on GPUs. We will also present two physical problems we resolve with Dyablo in solar physics and cosmology.
Contribute
Any subject is welcome if it is related to the Kokkos ecosystem (developments, usage, projects, issues, etc.) or even to GPU programming at large. Feel free to contact us to propose a talk: contact@cexa-project.org
We target very informal discussion in English. You can propose any subject for discussion even if you don’t have a dedicated slide deck.
Additional info
Join us physically in the Mandelbrot room
The Mandelbrot room of Digiteo Saclay building is in Saclay center, near the Orphée entrance.
