Reuti, Thank you. Our queue is backed up, so it will take a little while before I can try this.
I assume that by specifying the nodes this way, I don't need (and it would confuse the system) to add -nolocal. In other words, qsub will try to put the parent node somewhere in this set. Is this the idea?
