Enhancing Code Saturne's performance with usage of GPU

Post by rv82 »

Hello folks!

Is it possible to enhance Code Saturne's performance with usage of nVidia's or Radeon's GPU? If yes, then what I have to do, to get this enhancing? Is using of e.g. nVidia CUDA BLAS enough? Or may be exists some enhanced version of Scotch that can work on GPU?

Thank you!

Hello,

There is no current work on this on our side. Besides standalone tests (https://hal.archives-ouvertes.fr/hal-01662043), there have been tests on Power8 machines using PETSc, and I am aware of other tests which are in progress, but since the computational intensity is quite low (the code is more memory bound than compute bound), getting additional performance is not easy so using GPUs is not a priority.

Regards,

Yvan
