Carlos,
Open MPI 3.0.2 has been released, and it contains several bug fixes, so I do
encourage you to upgrade and try again.
if it still does not work, can you please run
mpirun --mca oob_base_verbose 10 ...
and then compress and post the output ?
out of curiosity, would
mpirun --mca ro
Nathan,
Same issue with OpenMPI 3.1.1 on POWER9 with GCC 7.2.0 and CUDA9.2.

Thank you all for your reply Jeff, Gilles and rhc.
Thank you Jeff and rhc for clarifying to me some of the openmpi's internals.

Just wanted to follow up on my own post.
Turns out there was a missing symlink (much embarrassment) on by build host.
That’s why you don’t see “pmix_v1” in the “srun —mpi=list” output (previous
post).
Once I fixed that and rebuilt SLURM, I was able to launch existing OpenMPI 3.x
apps with,
There is a name for my pain and it is “OpenMPI + PMIx”. :)
I’m looking at upgrading SLURM from 16.05.11 to 17.11.05 (bear with me, this is
not a SLURM question).
After building SLURM 17.11.05 with
‘--with-pmix=/opt/pmix/1.1.5:/opt/pmix/2.1/1’ and installing a test instance, I
see
$ srun --mp
Sorry for late response. But I just wanted to inform you that I found
another workaround, unrelated to the method we discussed here.

Hi,
I have successfully built Open MPI version 2.1.3 from scratch in Ubuntu 14.04 64 bit and using GCC 4.9. The result was the following shared libraries (needed for a program to use Open MPI):
dummy@machine:~/$ ldd /home/dummy/openmpi/build/lib/libmpi.so /home/dummy/openmpi/build/lib
