- Visibility: Public
- Change Control: Stable
- Details:
- Node object in PBS will have an additional attribute called "partition" which can be used to associate a node to a particular partition.
- This attribute will be of type string and it will be settable only by Manager/operator and viewable by all users.
- If "partition" attribute is not set, node will not belong to any partition and default scheduler will schedule jobs on this node.
- PBS admin/manager can set node's partition attribute to an existing partition name and it's corresponding scheduler will be scheduling jobs on this node.
- If nodes are associated to a partition then they can not be linked to any queue which isn't part of that partition. Trying to set a node to a queue which isn't part of it's partition will result into following error:
- qmgr -c "s n node1 queue=workq3"
workq3 is not part of partition <node's partition name>
- qmgr -c "s n node1 queue=workq3"
Nodes with a partition ID (but no queue statement) can run jobs from any of the queues assigned to the same partition (depending upon resource constraints).
- Node object in PBS will have an additional attribute called "partition" which can be used to associate a node to a particular partition.
