Just FYI: on master (and perhaps 4.0), child jobs do not inherit their parent's
mapping policy by default. You have to add “-mca rmaps_base_inherit 1” to your
mpirun cmd line.

On further investigation removing the "preconnect_all" option does change the

Removing the preconnect_all option didn't resolve the problem unfortunately.
I tried changing a few of the other options that I pass to mpirun. What does
seem to make a difference is the "--map-by node" option. If I remove that
option that my test code runs successfully - the output is in the
Thanks - I'll try removing that option.

I see you are using “preconnect_all” - that is the source of the trouble. I
don’t believe we have tested that option in years and the code is almost
certainly dead. I’d suggest removing that option and things should work.

I'm running into problems trying to spawn MPI processes across multiple nodes
on a cluster using recent versions of OpenMPI. Specifically, using the attached
Fortan code, compiled using OpenMPI 3.1.2 with:
mpif90 test.F90 -o test.exe
and run via a PBS scheduler using the attached test1.pbs, it
