Description Dominik 'Rathann' Mierzejewski 2018-01-18 11:04:54 UTC 
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.

Comment 1 Dominik 'Rathann' Mierzejewski 2018-01-18 11:10:44 UTC 
For now upstream worked around it by using MPI_ADDRESS_KIND which equals 4 in both OpenMPI and MPICH.
Comment 2 Fedora End Of Life 2018-02-20 15:21:48 UTC 
This bug appears to have been reported against 'rawhide' during the Fedora 28 development cycle.
Changing version to '28'.
Comment 3 Dominik 'Rathann' Mierzejewski 2018-02-21 10:54:47 UTC 
Reported upstream, too.
Comment 4 Zbigniew Jędrzejewski-Szmek 2018-04-04 08:43:09 UTC 
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.
