You don't *have* to do this, of course. If you've got it working
with ssh, that's fine. But the integration with torque can be better:

- you can disable ssh for non-root accounts (assuming no other
services need rsh/ssh)
- users don't have to setup ssh keys to run MPI jobs (a small thing,
but sometimes nice when the users aren't computer scientists)
- torque knows about all processes on all nodes (not just the mother
superior) and can therefore both track and kill them if necessary

Just my $0.02...
