Hello, I'm currently testing a preemtor/preemptee setup with maui 3.2.6p19 and torque 2.1.8.
My test env. is made of 2 nodes, each with 4 cpus If I start a 4-cpus job in the low priority queue and then a 8 cpu job (nodes=2:ppn=4), the first is suspended, and the high priority job is started. good. Now if instead of a 4 cpu job I try to run a one cpu job in the low priority queue, it is never suspended. Looking at the logs, it seems that maui doesn't count the 3 free cpus in the total number of procs available after the preemptible jobs are suspended: 07/09 13:46:47 MRECheck(helios39,MJobGetSNRange-Start,FORCE) 07/09 13:46:47 INFO: N[helios39]->RE[000] S 59(0) -00:00:03 R: 'PROCS: 1'x1 07/09 13:46:47 INFO: N[helios39]->RE[001] E 59(0) 99:23:59:56 R: 'PROCS: 1'x1 07/09 13:46:47 INFO: checking reservation 59 start at time -00:00:03 (O: 7200) 07/09 13:46:47 INFO: resources available at time -00:00:03 during 59 start 07/09 13:46:47 INFO: performing starttime check (1) 07/09 13:46:47 INFO: checking reservation 59 end at time 99:23:59:56 (O: 7200) 07/09 13:46:47 INFO: node helios39 supports 4 tasks of job 60:0 for INFINITY at 00:00:01 07/09 13:46:47 INFO: node helios39 contains preemptible resources (P: 1) 07/09 13:46:47 INFO: preemptible resources found.
