If both RESOURCE_RESERVE and SLOT_RESERVE are defined in the same queue, job slot reservation and memory reservation are both enabled and an error is displayed when the cluster is reconfigured. SLOT_RESERVE is ignored.
The following queue enables memory reservation for pending jobs:
Begin Queue
QUEUE_NAME = reservation
DESCRIPTION = For resource reservation
PRIORITY=40
RESOURCE_RESERVE = MAX_RESERVE_TIME[20]
End Queue
