[petsc-users] SuperLU + GPUs

Sherry, I did rebase with master this week:
SuperLU:
Version: 5.2.1
Includes: -I/ccs/home/adams/petsc/arch-summit-opt-gnu-cuda-omp/include
Library:
-Wl,-rpath,/ccs/home/adams/petsc/arch-summit-opt-gnu-cuda-omp/lib
-L/ccs/home/adams/petsc/arch-summit-opt-gnu-cuda-omp/lib -lsuperlu
I see the same thing with a debug build.
If anyone is interested in looking at this, I was also able to see that
plex/ex10 in my branch, which is a very simple test , also does not crash
and also does not seem to use GPUs in SuperLU.
