You mean to remove them from the nodes completely? This is tricky as SGE can't look ahead like: I will get an increment of h_vmem by 4 GB if I remove job 45636. For this you would need a co-scheduler. If jobs can still be scheduled to the node, then you could combine the subordination (which will suspend a queue instance and hence a job running therein) with a checkpointing interface to reschedule the low priority job when it gets suspended - so it's back to the waiting queue but at the top (instead of delete and resubmit the job, where it would be at the end). -- Reuti > On 1/12/2012 2:21 PM, Reuti wrote: >> Am 12.01.2012 um 13:14 schrieb Semi: >> >>> I have 3 queues.
