Shared vs Dedicated

SMP nodes are often used to run jobs that do not use all available resources on that node. How Moab handles these unused resources is controlled by the parameter NODEACCESSPOLICY. If this parameter is set to SHARED, Moab allows tasks of other jobs to use the resources. If this parameter is set to DEDICATED, Moab marks these resources unavailable for use by other jobs.

Reservations

As far as the resource manager allows, Moab tracks the aggregate usage of shared resources on a per job basis.
