I hope this email finds you well.

I am a student from Oakland University who is trying to use PETSc in my

I found that the PETSc 3.16 now is supporting the AMG preconditioner of
hypre on Nvidia and AMD GPU, however, do you use OpenCL to do it? or do you
use Cuda on Nvidia and Hip on AMD, if it is not OpenCL, how do you enable
it 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,
