Description Ron Lovell 2019-02-15 14:01:45 UTC
A known issue in libpsm2 11.2.23 (Intel IFS- causes a 15s delay starting programs when there are no hfi1 devices present on the system.
See https://github.com/intel/opa-psm2/issues/33. This issue is present in Tumbleweed, as I see delay when I try to start MPI programs with Open MPI
mpiexec(1) or mpirun(1).

Looking at https://github.com/intel/opa-psm2/releases it appears release IFS- corresponding to PSM2 11.2.77 addresses the issue.
I can only confirm that it's resolved on my systems with the current 11.2.78 builds on Debian Sid and Fedora Rawhide.

The issue causes a 15s delay when mpiexec(1)/mpirun(1) start an MPI program.
It also affects other programs linked to libpsm2. In my case, my MPI programs run normally, so it's just a nuisance, not a show-stopper.

Correction: That new release of IFS is, not
Comment 2 Ron Lovell 2019-02-15 14:23:35 UTC
I should have mentioned that I'm using openmpi3-3.1.1, not the default openmpi 1.10.7. The default version might not even link libpsm2.

The update to libpsm2-2 11.2.78-1.1 resolves the MPI start delay issue on my Tumbleweed x86_64 system. Great work, guys!
