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_tmpdir_base /some/place
ompi_info --param all all -l 9 | grep tmp
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)

I've compiled the linpack benchmark using openMPI 1.8.5 libraries
and include files on CentOS 6.4.
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
