you mean: his parallel jobs use SSH? It should work independend of
the node from which he submits.
It wiln work, but you will have neither accounting nor complete job
control, as SGE isn't aware that something was started on a node. You
a) recompile SGE with the flag -tight-ssh to get also a Tight SSH
b) Can he adjust his calls to use rsh instead? Often this can be done
by setting an environment variable, and override the compiled-in
