    <p>Hei,</p>

    <p>I tried to combine CUDA with superlu_dist in petsc using the

      following configure-line:</p>

    <p><i>./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</i></p>

    <p>but the configure-step fails with several errors correlated with

      CUDA and superlu_dist, the first one being</p>

    <p><i>cublas_utils.c:21:37: error: ‘CUDART_VERSION’ undeclared

        (first use in this function); did you mean ‘CUDA_VERSION’?</i><i><br>

      </i><i>   21 |     printf("CUDA version:   v

        %d\n",CUDART_VERSION);</i><i><br>

      </i><i>      |                                     ^~~~~~~~~~~~~~</i><i><br>

      </i><i>      |                                     CUDA_VERSION</i></p>

    <p>Compiling superlu_dist separately works, though (including CUDA).</p>

    <p>Is there a bug somewhere in the configure-routine? I attached the

      full configure-log.<br>

    </p>

    <p>Thanks!</p>

    <p>Regards,</p>

    <p>Roland<br>
