I've used SR's with decent success for blocking out access during lab times.
Example: SRCFG[bloc122mw] GROUPLIST=root SRCFG[bloc122mw] STARTTIME=07:30:00 SRCFG[bloc122mw] ENDTIME=17:00:00 SRCFG[bloc122mw] DAYS=MON,WED SRCFG[bloc122mw] HOSTLIST=bloc122-[00-32] I also do pbsnodes -o via cron to mark the nodes offline so that Globus MDS reports the correct number of available nodes. It also provides a second layer of protection against a job starting when it's not suppose to. It's a different story when using SR's in place of partitions. I just couldn't get it to behave as desired in terms of keeping jobs from particular classes separated, so I went back to partitions. // Steve Tom Rudwick wrote: > I recommend not using standing reservations.
