[petsc-users] Preliminaries to use gpu capabilities

[Edoardo alinovi]

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!
