That didn't travel well from the midst of the Peak District. I meant if you use ssh (or rsh) for the communication, you can wrap it to set up ssh forwarding of the chosen port (I think -- I've not done it). > AFAIK is always a random one used - being it `ssh`, `rsh` or > -builtin-.

[In case anyone wonders, it's a random port because SGE needs to be able to start multiple instances of the communication daemon program under its control; I'm not sure if that's spelt out anywhere.] > But MPI needs random ports being open too.

How do people typically run more loosely-coupled systems, like desktops, under SGE, though? _______________________________________________ users mailing list [email protected] https://gridengine.org/mailman/listinfo/users
