[petsc-users] Petsc support for BoomerAMG from PCHYPRE to run on Nvidia and AMD GPUs

[Qi Yang]

To whom it may concern,

Hope this email finds you well.

I am a student from Oakland University who is trying to use Petsc in my
project.

I found that the Petsc 3.16 now is supporting AMG preconditioner of hypre
with gpu on Nvidia and AMD card, however, do you use openCL to realize it ?
or do you realize it by using cuda on Nvidia and hip on AMD, if it is not
openCL, how do you enable with flag? like -pc_hypre_gamg_mat_type
aijcusparse or just -mat_type aijcusparse(which is already used in former
edition)?

Sorry for the disturbance, I did not find the answer in your document,
looking forward to hearing from you soon.

Appreciate your time.

Best regards,
Qi
