I did not configure hypre manually, so I guess it is not using GPUs.

FYI, I seem to have the new GPU machine at ORNL (summitdev) working with
GPUs. That is good enough for now.
Thanks,

-dm_vec_type cuda -dm_mat_type aijcusparse -pc_type none -ksp_type fgmres
-snes_monitor_short -snes_rtol 1.e-5
And I just tested it with GAMG and it seems fine. And hypre ran, but it is
not clear that it used GPUs

Presumably hyper must be configured to use GPUs. Currently the PETSc hyper
download installer hypre.py doesn't have any
