Subject: Re: [OMPI users] Question regarding mpirun options with ompi-restart

I'll preface my response with the note that I have not tried any of
those options with the C/R functionality. It should just work, but I
am not 100% certain. If it doesn't, let me know and I'll file a bug to
fix it.

You can pass any mpirun option through ompi-restart by using the
--mpirun_opts option.

So something like:
  shell$ ompi-restart --mpirun_opts "-npernode 2" ompi-global-snapshot-1234
