I have been having some difficulties getting the right combination of
SLURM, PMIx, and OMPI 3.1.x (specifically 3.1.2) to compile in such a way
that both the srun method of starting jobs and mpirun/mpiexec will also run.
If someone has a slurm 18.08 or newer, PMIx, and OMPI 3.x that works with
both srun and mpirun and wouldn't mind sending me the version numbers and
any tips for getting this to work, I would appreciate it.
Should mpirun still work? If that is just off the table and I missed the
memo, please let me know.
I'm asking for both because of programs like OpenFOAM and others where
mpirun is built into the application. I have OMPI 1.10.7 built with
similar flags, and it seems to work.
[bennet@beta-build mpi_example]$ srun ./test_mpi
The sum = 0.866386
Elapsed time is: 0.000458
[bennet@beta-build mpi_example]$ mpirun ./test_mpi
The sum = 0.866386
Elapsed time is: 0.000295
SLURM documentation doesn't seem to list a recommended PMIx, that I can
find. I can't find where the version of PMIx that is bundled with OMPI is
specified.
I have slurm 18.08.0, which is built against pmix-2.0.2. We settled on
that version with SLURM 17.something prior to SLURM supporting PMIx 2.1.
Is OMPI 3.1.2 balking at too old a PMIx?
Sorry to be so at sea.
I built OMPI with
./configure \
--prefix=${PREFIX} \
--mandir=${PREFIX}/share/man \
--with-pmix=/opt/pmix/2.0.2 \
--with-libevent=external \
--with-hwloc=external \
--with-slurm \
--with-verbs \
--disable-dlopen --enable-shared \
CC=gcc CXX=g++ FC=gfortran
I have a simple test program, and it runs with
[bennet@beta-build mpi_example]$ srun ./test_mpi
The sum = 0.866386
Elapsed time is: 0.000573
but, on a login node, where I just want a few processors on the local node,
not to run on the compute nodes of the cluster, mpirun fails with
[bennet@beta-build mpi_example]$ mpirun -np 2 ./test_mpi

It looks like orte_init failed for some reason; your parallel process is
likely to abort. There are many reasons that a parallel process can
fail during orte_init; some of which are due to configuration or
environment problems. This failure appears to be an internal failure;
here's some additional information (which may only be relevant to an

Primary job terminated normally, but 1 process returned
a non-zero exit code. Per user-direction, the job has been aborted.

mpirun detected that one or more processes exited with non-zero status,
thus causing
the job to be terminated. The first process to do so was:
Process name: [[13610,1],0]
Exit code: 1
