Do you define the slots in the host definition and not the queue setting in Torque? In SGE the amount of slots for each queue instance residing on a maschine is defined in the queue definition. It should be set to 64 in your case. If you have one and only one queue, there is no need to set any slotcount in the exechost definition. If you have two queue instances on a maschine, and want to limit the number of slots across both queue instances to avoid oversubscription, you need to define the overall limit in the exechost definition (to be complete: or in an RQS, but ignre it for now). Having a limit defined in the exechost definition, you can be sure that the node will never run more processes than defined slots (often set to the real number of cores in a maschine). == In your case: define 64 slots in each queue, and don't limit the number of slots across all queues in the exechost definition. -- Reuti > I *DO* understand that a suspended job will keep pages in memory.
