Sure, I’ll ask the machine admins to update and let you know how it goes.
In the meantime, I was just wondering if someone has run this little program
with an up-to-date OpenMPI and if it worked. If so, then I will know the
problem is with our setup.
Thanks

You cited Open MPI v2.1.1. That's a pretty ancient version of Open MPI.
Any chance you can upgrade to Open MPI 4.0.x?

OK, but then on this other machine it hangs. This one is using SLURM, so I’m
not exactly sure but I think this tells me the OpenMPI version:
siegel@cisc372:~$ mpiexec.openmpi --version
mpiexec.openmpi (OpenRTE) 2.1.1

It looks like your output somehow
Your code looks correct, and based on your output I would actually suspect that
the I/O part finished correctly, the error message that you see is not an IO
error, but from the btl (which is communication related).
What version of Open MPI are using, and on what file system?
Thanks
