Our first CExA virtual coffee will take place on Monday, November the 27th, 2023 starting at 1PM. It can be followed on Zoom, by phone, from a visio room or from the Mandelbrot room in the Digiteo Saclay building.

Baptiste Legouix will give a talk entitled “Performance portable Fourier & Spline transforms for Vlasov-Poisson numerical solve”

Performance portable Fourier & Spline transforms for Vlasov-Poisson numerical solve

Numerical changes of basis functions is a very usefull tool for numerical simulation: involved in interpolations, integrations, PDE solvers… In the context of a collaboration between Mdls and IRFM, a Fourier and a Spline transform kernels have been developed and integrated in the library DDC to address the use-case of the gyrokinetic code Gysela in a performance perspective (compatibility with GPU).

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

Kokkos Korner

For those interested, the coffee will be followed by a “Kokkos Korner”. If you’ve tried Kokkos tutorials and you’re stuck, if you have issues with Kokkos use, our experts will be available at 2PM in Si vous avez essayé les tutoriaux Kokkos et que vous êtes bloqués, si vous avez des difficultés avec son utilisation, nos experts Kokkos seront disponibles à 14h au même endroit pour répondre à vos questions. Pour ceux qui ne peuvent pas se déplacer sur Saclay, nous sommes joignable sur le slack de Kokkos : https://kokkosteam.slack.com/messages , canal #general-fr.
