[petsc-users] Combining SUPERLU_DIST with CUDA fails

[Roland Richter]

Hei,

I tried to combine CUDA with superlu_dist in petsc using the following
configure-line:

/./configure PETSC_ARCH=mpich-complex-linux-gcc-demo
--CC=/opt/intel/oneapi/mpi/2021.5.0/bin/mpicc
--CXX=/opt/intel/oneapi/mpi/2021.5.0/bin/mpicxx
--FC=/opt/intel/oneapi/mpi/2021.5.0/bin/mpifc --CFLAGS="-mavx2
-march=native -O3" --CXXFLAGS="-mavx2 -march=native -O3"
--FFLAGS="-mavx2 -march=native -O3"
--CUDAFLAGS=-allow-unsupported-compiler --CUDA-CXX=g++
--prefix=/opt/petsc --with-blaslapack=1 --with-mpi=1
--with-scalar-type=complex --download-suitesparse=1 --with-cuda
--with-debugging=0 --with-openmp --download-superlu_dist --force/

but the configure-step fails with several errors correlated with CUDA
and superlu_dist, the first one being

/cublas_utils.c:21:37: error: ‘CUDART_VERSION’ undeclared (first use in
this function); did you mean ‘CUDA_VERSION’?//
//   21 |     printf("CUDA version:   v %d\n",CUDART_VERSION);//
//      |                                     ^~~~~~~~~~~~~~//
//      |                                     CUDA_VERSION/

Compiling superlu_dist separately works, though (including CUDA).

Is there a bug somewhere in the configure-routine? I attached the full
configure-log.

Thanks!

Regards,

Roland
