Ralph,
the cxx_win_attr issue is dealt at
https://github.com/open-mpi/ompi/pull/1473
iirc, only big endian and/or sizeof(Fortran integer) > sizeof(int) is
impacted.
the second error seems a bit weirdest at a time.
once in a while, MPI_File_open fails, and when it fails, it always fails
silently.
in this case (MPI_File_open failed), if --mca mpi_param_check true, then
next calls to MPI-IO will also fail silently.
if --mca mpi_param_check false (or Open MPI was configure'd with
--without-mpi-param-check),
then something will go wrong in MPI_File_close
that raises several questions ...
- why does MPI-IO default behavior is to fail silently ?
(point to point or collective will abort by default)
- why does MPI_File_open fails once in a while ?
(Open MPI bug ? ROMIO bug ? intermittent failure caused by the NFS
filesystem ?)
- is there a bug in the test ?
for example, the program could abort with error code 77 (skip) if
MPI_File_open fails
Cheers,
Gilles
