Hello Petsc friends, As many people is doing, I would like to explore a bit gpu capabilities (cuda) in petsc.
Before attemping any coding effort I would like to hear from you if all of this make sense: - compile mpi with cuda support - compile petsc with cuda support - build matrix and vectors as MATAIJCUSPARSE and VECMPICUDA to tell petsc using gpu. That's really it or do I need to take care of something else? I have seen that there is an amgXWrapper library aroud, but not sure if it is still relevant now or not. Thank you for the suggestions!
