You can run on AMD GPUs now with -dm_vec_type kokkos -dm_mat_type aijkokkos,
for example. GAMG works that way, with the PtAP setup on device. If you use
MatSetValuesCOO, then matrix assembly is also entirely on-device.

Hi Qi, Mark,
My colleague Suyash Tandon has almost completed a PETSc HIP port
(essentially a hipification of the CUDA port) and has been trying to test
it on the same OpenFOAM 3D Lid-driven case. It would be interesting to see
what the optimal HYPRE parameters are as we could experiment from the A
Hi Mark,
Sure, I will try a 3D Lid-driven case by combining OpenFOAM, PETSc and
HYPRE, let's see what would happen.
Kind regards,
Qi

Hi Qi, these are good discussions and data and we like to share, so let's
keep this on the list.
* I would suggest you use a 3D test. This is more relevant to what HPC
applications do.
* In my experience, hypre's default parameters are tuned for 2D low order
problems like this so I would start wit
