This is to introduce the node ramp down feature, which basically releases no longer needed sister nodes early from running jobs.
Interface 1: New command: 'pbs_release_nodes'
Visibility: Public
Change Control: Stable
Synopsis: Release a specified set of sister nodes or vnodes, or all sister nodes or vnodes assigned to the specified job. The nodes released will then be made available for scheduling other jobs.
Permission: Only job owner, admin, PBS manager, or PBS operator will be allowed to perform the release nodes action.
