Can you clarify what "suspension" means? is it SIGSTOP; followed by SIGCONT when resources are free? As mentioned we don't want jobs to swap out, but hadn't considered subordinate_list, since it is not something we are familiar with. If my new understanding is correct, we can forget about using injecting nice into qsub; and get the desired effect with subordinate_list and queue priority alone? Is there any way (best way) to prevent stopped jobs from swapping out? Regards, -George -- George Georgalis, (415) 894-2710, http://www.galis.org/
