For now upstream worked around it by using MPI_ADDRESS_KIND which equals 4 in both OpenMPI and MPICH. This bug appears to have been reported against 'rawhide' during the Fedora 28 development cycle. Changing version to '28'. Reported upstream, too. Upstream bug was closed as "it's an opaque handle is because different MPI implementations can define it differently". I'll just go with upstream says. |
Description of problem: MPI_OFFSET_KIND=4 in OpenMPI while it equals 8 in MPICH on 32bit arches. I don't know which is correct, but this difference has caused compilation issues in cp2k-5.1 with MPICH: [...] /builddir/build/BUILD/cp2k-5.1/src/mpiwrap/message_passing.F:3588:70: type_descriptor%type_handle, ierr) 1 Error: Type mismatch in argument 'array_of_displacements' at (1); passed INTEGER(8) to INTEGER(4) [...] Version-Release number of selected component (if applicable): openmpi-2.1.1-5.fc28.i686 mpich-3.2.1-2.fc28.i686 How reproducible: Always Steps to Reproduce: 1. grep MPI_OFFSET_KIND= mpich-i386/mpif.h mpich-i386/mpiof.h openmpi-i386/mpif-config.h Actual results: mpich-i386/mpif.h: PARAMETER (MPI_OFFSET_KIND=8) mpich-i386/mpiof.h: PARAMETER (MPI_OFFSET_KIND= 8) openmpi-i386/mpif-config.h: parameter (MPI_OFFSET_KIND=4) Expected results: The value should be the same across MPI implementations.
