We are running Maui 3.3.1 and Torque 2.5.3 on Centos 5.6 and are having problems getting standing reservations to work the way we want. We have a handful of groups of users that have purchased nodes in our cluster. They would like to be able to get access to the resources that they paid for without having to wait, but we would like the resources to get utilized when they aren't being used. I think that we should be able to accomplish this with standing reservations and preemption. I had the below configuration running last week and a user in group1 had a job in the queue that was going to have to wait over a day to run. At that time it looked to me like there were nodes reserved with the fluent reservation, but they were sitting idle and not allowing his job to run. Does anybody see anything wrong with the config file to not allow jobs to run in this reservation? How about the overall goal of standing reservations that allow all users in, but owners are allowed to preempt?
We have very similar needs and configuration, I have torque 2.5.5, maui 3.3.1 and centos 5.6.
My current configuration, however, is not using standing reservation. The relevant parts are: PREEMPTPOLICY SUSPEND USERCFG[DEFAULT] MAXJOB=8,16 MAXPROC=128,256 MAXJOBQUEUED=8QOSCFG[climahigh] PRIORITY=100000 MAXPROC=64 MAXJOB=2 QFLAGS=PREEMPTOR,RESTARTPREEMPT
QOSCFG[DEFAULT] PRIORITY=0 QFLAGS=PREEMPTEE CLASSCFG[short] PRIORITY=20000 CLASSCFG[climahigh] PIORITY=50000 QDEF=climahigh QLIST=climahigh:DEFAULTWe use features on torque to differentiate between nodes whih belongs to the clima group and "general use" nodes.
I've not tested it extensively, but for now it seems to work. .a. -- Antonio Messina I.T. Specialist email: [email protected] | The Abdus Salam ICTP phone: +39 040-2240-691 | Strada Costiera, 11 fax: +39 040-2240-7691 | 34151 Trieste, Italy
