This is just a guess but - is it possible after building slurm
against PMIx, you should build openmpi against SLURM's PMIx
instead of directly using external? I would assume slurm's PMI
server now "knows" PMIx.

HI Gilles,
I tried both “—with-pmix=/opt/pmix” and “—with-pmix=internal” and got the same
“UNREACHABLE” error both ways. I tried the “external” first since that is what
SLURM was built against.
I’m missing something simple/basic - just not sure what it is.
Thanks,
Charlie

Charles,
did you build Open MPI with the external PMIx ?
iirc, Open MPI 2.0.x does not support cross version PMIx
Cheers,
Gilles

Anyone successfully using PMIx with OpenMPI and SLURM? I have,
1. Installed an “external” version (1.1.5) of PMIx.
2. Patched SLURM 15.08.13 with the SchedMD-provided PMIx patch (results in an
mpi_pmix plugin along the lines of mpi_pmi2).
3. Built OpenMPI 2.0.1 (tried 2.0.3 as well).
However,
