- Visibility: Public
- Change Control: Experimental
- Details:
- New interface: new mom_priv/config variable.
- alps_create_vnode_per_numa is a Boolean. Setting it to "TRUE" will cause PBS to create one vnode per Cray numa node. This is the
default behavior when alps_create_vnode_per_numa is not set in mom_priv/config. Setting it to "FALSE" will cause PBS to create
one vnode per Cray compute node. - New interface: new mom_priv configure variable.
- NOTENote: when alps_create_vnode_per_numa is set to "FALSE", it will not be possible for PBS to schedule based on segments.
...
- When changing from using one type of vnode create versus another, you must first:
- Quiesce the system (ensure there are no running jobs).
- Remove all existing vnodes of the vntype cray_compute. The easiest way to do this is to delete all vnodes using
- qmgr -c "delete node @default"
- Set the mom_priv configuration /config variable to desired setting in each MoM.
- HUP or restart the MoM.
- Add the MoMs back using qmgr: qmgr -c "create node <mom name>"
