It's also worth noting that because of problem reports about PMI2 with Slurm to the OMPI developers there was discussion about disabling PMI2 by default for Slurm. See the thread "RFC: Force Slurm to use PMI-1 unless PMI-2 is specifically requested" that starts here: http://www.open-mpi.org/community/lists/devel/2014/05/14690.php # We have been seeing a lot of problems with the Slurm PMI-2 support # (not in OMPI - it's the code in Slurm that is having problems). At # this time, I'm unaware of any advantage in using PMI-2 over PMI-1 # in Slurm - the scaling is equally poor, and PMI-2 does not supports # any additional functionality. # # I know that Cray PMI-2 has a definite advantage, so I'm proposing # that we turn PMI-2 "off" when under Slurm unless the user # specifically requests we use it. Not sure if this has been raised on slurm-dev yet.
