Thanks Gilles - I appreciate all the detail.
Ahh, that's great that Open MPI now supports specifying an ssh port simply
through the hostfile. That'll make things a little simpler when I have
that use case in the future.
Oh of course - that makes sense that Open MPI requires TCP ports too rather
Adam,
there are several things here
with an up-to-date master, you can specify an alternate ssh port via a

Open MPI requires more than just ssh.
- remote nodes (orted) need to call back mpirun (oob/tcp)
- nodes (MPI tasks) need
