[petsc-users] SuperLU + GPUs

Wed Apr 15 19:17:08 CDT 2020

Ah, OK 'check' will test SuperLU. Semi worked:

s20:13 mark/feature-xgc-interface-rebase *= ~/petsc$ make
PETSC_DIR=/ccs/home/adams/petsc PETSC_ARCH=arch-summit-dbg-gnu-cuda-omp
check
Running check examples to verify correct installation
Using PETSC_DIR=/ccs/home/adams/petsc and
PETSC_ARCH=arch-summit-dbg-gnu-cuda-omp
C/C++ example src/snes/tutorials/ex19 run successfully with 1 MPI process
C/C++ example src/snes/tutorials/ex19 run successfully with 2 MPI processes
