Sorry, but don't follow. Are you talking about perceus modules? I didn't think we wanted standard passwd/group files sent to the nodes, which is what perceus normally does. I can't even find where xcpu stores the information for xgroupset/xuserset! (I guess this shows that it is not trivial to get into the xcpu code...). Also, what do you mean by the "-u" switch for xcpu? Oh, I just looked at xcpufs.c and I see it there - it is not in the man page for xcpufs, though... I guess this would do the trick if we simply want all users and groups to be authenticated on the nodes at all time. I would much prefer to have the batch queuing systems do this on a job-by-job basis, sort of like the node ownership setting that bjs does on bproc clusters, since this would prevent people from running interactively on the nodes that are owned by someone else.
