The following is fairly annoying (though I understand the problem is real):
$ [full-path-to]/mpirun -mca btl sm,self -np 2 examples/ring_c
PMIx has detected a temporary directory name that results
in a path that is too long for the Unix domain socket:
Temp dir:
/var/folders/mg/q0_5yv791yz65cdnbglcqjvc0000gp/T/openmpi-sessions-502@anlextwls026-173_0
/53422
Try setting your TMPDIR environmental variable to point to
something shorter in length
Of course this comes from the fact that something outside my control has
set TMPDIR to a session-specific directory (same value as $XDG_RUNTIME_DIR)
TMPDIR=/var/folders/mg/q0_5yv791yz65cdnbglcqjvc0000gp/T/
I am just reporting this for three minor reasons
1) Just in case nobody was aware of this problem
2) To request that an FAQ entry related to this be added
3) Yes, the message is clear, but it could be improved by indicating the
allowable length of $TMPDIR
