Hello -
We are starting to see some mpi processes "hang" (really cpu spin and
never complete) on 32 bit architectures on Fedora during package tests.
Some examples:
hpl 2.2 and openmpi 2.1.5 on i686 and arm:
https://koji.fedoraproject.org/koji/taskinfo?taskID=31129461
hdf5 1.8.20 and openmpi 3.1.3 on i686 with the "t_cache" test.
https://copr-be.cloud.fedoraproject.org/results/@scitech/openmpi3.1/fedora-28-i386/00830432-hdf5/builder-live.log
I'm at a loss as to how to debug this further.
