As you note, there is no correlation between release number and libtool
versioning. The comment in VERSION explains the libtool rules and you can see
why the two values differ.
The PMIx master is at release version 3.0 as it includes new APIs that have not
yet been released. The configure
I made a good deal of progress, and I now have OpenMPI 3.0.0 capable
of being run.
I do have one final point of confusion, however. It appears that
--with-pmi= fails because configure is testing for
a non-existent major version of PMIx, 3. Perhaps that is the major
version of the OMPI
Hi Bennet
I suspect the problem here lies in the slurm PMIx plugin. Slurm 17.11 supports
PMIx v2.0 as well as (I believe) PMIx v1.2. I’m not sure if slurm is somehow
finding one of those on your system and building the plugin or not, but it
looks like OMPI is picking up signs of PMIx being
I might be offbase here, but I think what was implied is that
you've built openmpi with --with-pmi without supplying the path
that holds pmi2 libs.
First build slurm with pmi, then build openmpi with path to pmi
so in slurm.
That might not provide pmix, but it
Howard,
Thanks for the reply.
I think, based on a previous reply, that we may not have the right
combinations of pmi and slurm lined up. I will have to coordinate with our
admin who compiles and installs slurm, and once we think we have slurm with
pmix, I'll try again and post the
Hello Bennet,
What you are trying to do using srun as the job launcher should work.
Could you post the contents
of /etc/slurm/slurm.conf for your system?
Could you also post the output of the following command:
ompi_info --all | grep pmix
to the mail list.
the config.log from your build would
What Charles said was true but not quite complete. We still support the older
PMI libraries but you likely have to point us to wherever slurm put them.
However,we definitely recommend using PMIx as you will get a faster launch

Charlie,
Thanks a ton! Yes, we are missing two of the three steps.
Will report back after we get pmix installed and after we rebuild
Slurm. We do have a new enough version of it, at least, so we might
have missed the target, but we did at least hit the barn. ;-)

I think that OpenMPI is supposed to support SLURM integration such that
srun ./hello-mpi
should work? I built OMPI 2.1.2 with
export CONFIGURE_FLAGS='--disable-dlopen --enable-shared'
export COMPILERS='CC=gcc CXX=g++ FC=gfortran F77=gfortran'
CMD="./configure \
--prefix=${PREFIX} \
