Hello,
When PETSc is installed with GPU support, will it run only on GPUs or can it be
run on CPUs (without GPUs)? Currently, PETSc crashes when run on CPUs.
Thank you.
Best regards,
Karthik.

Hi Barry,
Thanks, I am interested in this PCMPI solution provided by PETSc!
I tried the src/ksp/ksp/tutorials/ex1.c which is configured in CMakelists as
follows:
./configure PETSC_ARCH=config-debug --with-scalar-type=complex
--with-fortran-kernels=1 --with-debugging=0 --with-logging=0 --with-c
