Enable GPU support in MFEM + hypre example. #14

Closed balos1 closed 2 years ago

luszczek commented 2 years ago

I get an error in mfem/hypre-superlu/CMakeFiles/convdiff.dir/build.make due to missing variables:

mfem/hypre-superlu/convdiff: SUNDIALS::PETSC_VEC-NOTFOUND
mfem/hypre-superlu/convdiff: SUNDIALS::PETSC_SNES-NOTFOUND

The message is:

mfem/hypre-superlu/CMakeFiles/convdiff.dir/build.make:114: *** target pattern contains no `%'.  Stop.

I get the same:

mfem/petsc/CMakeFiles/obstacle.dir/build.make:113: *** target pattern contains no `%'.  Stop.

and:

mfem/sundials/CMakeFiles/transient-heat.dir/build.make:109: *** target pattern contains no `%'.  Stop.

I added a new GPU-enabled MFEM+HYPRE example in https://github.com/xsdk-project/xsdk-examples/tree/balos1/updates commit 886b8b0.

I think the example mfem/hypre-superlu/convdiff.cpp can also be modified slightly to enable GPU support when using HYPRE, at least; usinig GPU-enabled SuperLU in MFEM is not tested and may require some additions in MFEM.

@luszczek, I encountered the same issue as you -- it should be fixed now in this Spack branch: https://gitlab.com/xsdk-project/spack-xsdk/-/tree/xsdk-examples -- it was an issue with a cmake file in SUNDIALS.
