Cool thanks Reuti. Now the parallel job suspends the equal number of 1-core jobs. So a single 8-core job suspends 8 1-core jobs. Best, Joseph On 6/24/2012 2:27 AM, Reuti wrote:

When I set suspend_thresholds to .9, all 16 1-core jobs get suspended instead of 8 cores. Or are you saying that a parallel job using 8-cores cannot suspend 8 1-core jobs?correct. At least it's not working for slotwise subordination, for the traditional format it should work. If you specify just: subordinate_list free=1 it should suspend all jobs in "free" as soon as one slot is used in the superordinated queue. -- ReutiJoseph On 6/22/2012 5:43 AM, Reuti wrote:Hi, Am 22.06.2012 um 05:17 schrieb Joseph Farran:I am playing with subordinate queues. I have defined "owner" queue and "free" queue. The owner queue has: # qconf -sq owner | grep subordinate subordinate_list slots=8(free:0:sr) If I submit a 1-core job to owner queue, OGE suspends 1 core (slot) job from free queue. If I submit another 1 core job to owner queue, OGE suspend another 1 core job from free queue and so on. All is well. Now, if I submit a parallel job that uses 8 cores, OGE will still suspend 1 core job and not 8 1-core jobs, so the node is now over subscribed. What is the trick in telling OGE to suspend 8 slots if an 8 slot job is submitted?yes, it's not working with slotweise subordination. If you use the original synatx by specifying a threshold, all will be suspended as expected. -- Reuti |
