I think that is a good idea. I am trying to do it myself but it is getting messy. Thanks, On Wed, Jul 7, 2021 at 9:50 AM Stefano Zampini <[email protected]> wrote:
Do you want me to open an MR to handle the sequential case?

OK, I found where its not protected in sequential.

Thanks, but that did not work.
It looks like this is just in MPIAIJ, but I am using SeqAIJ. ex2 (below) uses PETSC_COMM_SELF everywhere.

Stefano has mentioned this before. He reported cuSparse matrix-matrix vector products use a very amount of memory.

I am running out of memory in GAMG. It looks like this is from the new cuSparse RAP. I was able to run Hypre with twice as much work on the GPU as this run. Are there parameters to tweek for this perhaps or can I disable it?
Thanks, Mark
