I checked the v1.10 source code, and for some reasons, it seems
rmaps_rank_file_path is defined.
before invoking mpirun, can you please run
ompi_info --all | grep rmaps_rank_file
and confirm that
Cheers,

Hi all,
We have an application named "GAMESS" that worked fine with OpenMPI
v1.8.4 but having problems with v1.8.8.
The mpi command in the application is:
orterun --oversubscribe -mca hwloc_base_binding_policy
core:overload-allowed -np $NPROCS --npernode $PPN2
$GMSPATH/gamess.$VERNO.x < /dev/null
The above command works for v1.8.4 but for v1.8.8, it give the
following error:
--------------------------------------------------------------------------
Conflicting directives for mapping policy are causing the policy
to be redefined:
New policy: RANK_FILE
Prior policy: BYCORE:OVERSUBSCRIBE
Please check that only one policy is defined.
--------------------------------------------------------------------------
We used to have binding issues with v1.8.8 which led to poor
application performances. To resolve it, we added the following
parameters to the "openmpi-mca-params.conf" file:
orte_hetero_nodes=1
hwloc_base_binding_policy=core
rmaps_base_mapping_policy=core
The above changes in v1.8.8 work great for other stuff but breaks
GAMESS. Does anyone know how to resolve the conflict? Any suggestion
is appreciated.
Thanks,
