[petsc-users] Compiling PETSc with strumpack in ORNL Frontier

[Vanella, Marcos (Fed)]

Hi all, we are trying to compile PETSc in Frontier using the structured matrix hierarchical solver strumpack, which uses GPU and might be a good candidate for our Poisson discretization.
The list of libs I used for PETSc in this case is:

$./configure COPTFLAGS="-O3" CXXOPTFLAGS="-O3" FOPTFLAGS="-O3" FCOPTFLAGS="-O3" HIPOPTFLAGS="-O3 --offload-arch=gfx90a" --with-debugging=0 --with-cc=cc --with-cxx=CC --with-fc=ftn --with-hip --with-hip-arch=gfx908 --with-hipc=hipcc   --LIBS="-L${MPICH_DIR}/lib -lmpi ${CRAY_XPMEM_POST_LINK_OPTS} -lxpmem ${PE_MPICH_GTL_DIR_amd_gfx90a} ${PE_MPICH_GTL_LIBS_amd_gfx90a}" --download-kokkos --download-kokkos-kernels --download-suitesparse --download-hypre --download-superlu_dist --download-strumpack --download-metis --download-slate --download-magma --download-parmetis --download-ptscotch --download-zfp --download-butterflypack --with-openmp-dir=/opt/cray/pe/gcc/12.2.0/snos --download-scalapack --download-cmake --force

I'm getting an error at configure time:

 Looking in the configure.log file I see error like this related to strumpack compilation:

/opt/cray/pe/craype/2.7.19/bin/CC -D__HIP_PLATFORM_AMD__=1 -D__HIP_PLATFORM_HCC__=1 -Dstrumpack_EXPORTS -I/autofs/nccs-svm1_home1/vanellam/Software/petsc/arch-linux-frontier-opt-gcc-direct/externalpackages/git.strumpack/src -I/autofs/nccs-svm1_home1/vanellam/Software/petsc/arch-linux-frontier-opt-gcc-direct/externalpackages/git.strumpack/petsc-build -isystem /autofs/nccs-svm1_home1/vanellam/Software/petsc/arch-linux-frontier-opt-gcc-direct/include -isystem /opt/rocm-5.4.0/include -isystem /opt/rocm-5.4.0/hip/include -isystem /opt/rocm-5.4.0/llvm/lib/clang/15.0.0/.. -Wno-lto-type-mismatch -Wno-psabi -O3 -fPIC -fopenmp -Wno-lto-type-mismatch -Wno-psabi -O3 -fPIC -fopenmp -fPIC -Wall -Wno-overloaded-virtual -fopenmp -x hip --offload-arch=gfx900 --offload-arch=gfx906 --offload-arch=gfx908 --offload-arch=gfx90a --offload-arch=gfx1030 -MD -MT CMakeFiles/strumpack.dir/src/clustering/NeighborSearch.cpp.o -MF CMakeFiles/strumpack.dir/src/clustering/NeighborSearch.cpp.o.d -o CMakeFiles/strumpack.dir/src/clustering/NeighborSearch.cpp.o -c /autofs/nccs-svm1_home1/vanellam/Software/petsc/arch-linux-frontier-opt-gcc-direct/externalpackages/git.strumpack/src/clustering/NeighborSearch.cpp

It seems the configure is picking up CC (g++) instead of hipcc as the compiler for strumpack.

I wonder if anyone has come across this issue or has any suggestions?
Thanks!
Marcos
