You can also change the location of tmp files with the following mca option:
-mca orte_tmpdir_base /some/place
ompi_info --param all all -l 9 | grep tmp
MCA orte
You can also change the location of tmp files with the following mca option:

MCA orte: parameter "orte_tmpdir_base" (current value: "", data
source: default, level: 9 dev/all, type: string)
Bill,
the root cause is likely there is not enough free space in /tmp.
the simplest, but slowest, option is to run mpirun --mac btl tcp ...
if you cannot make enough space under /tmp (maybe you run diskless)
there are some options to create these kind of files under /dev/shm

I've tested the binary on the one Intel node (some
sort of 4-core Xeon) and it runs, but when I try to run it on any of
the old Sunfire opteron compute nodes it appears to hang (although
