[petsc-dev] cuda with kokkos-cuda build fail

Fri Jan 7 11:17:38 CST 2022

These are cuda/cusparse tests. The Kokkos versions are fine and cusparse
w/o a Kokkos build is fine.

I do have some #ifdefs in the code. Maybe something snuck into the #ifdef
KOKKOS, but I can't imagine what that could even be.

I have had problems with very large "cuda" jobs (on Summit with 21 MPI
processes per GPU) running out of "resources" with a Kokkos build, that
went away with a pure CUDA build (ie, w/o Kokkos), but these are tiny tests.

I will try it again.

Thanks,
