• Visibility: PBS Private
• Change Control: Experimental
• Details:
  • New interface: new mom_priv/config variable.
  • vnode_per_numa_node is a Boolean. 
    Setting it to FALSE will cause PBS to create one vnode per Cray compute node.  This is the default behavior
    when $vnode_per_numa_node is not set in mom_priv/config.
    Setting it to TRUE will cause PBS to create one vnode per Cray numa node.
  • the value of vnode_per_numa_node should be set to the same value on all of the PBS moms for that Cray system.
    
    

Interface: PBScrayseg

• resources_available.PBScrayseg will be set to 0 when vnode_per_numa_node is unset or set to FALSE
• resources_available.PBScrayseg will be set to the segment ordinal of the associated NUMA node when vnode_per_numa_node is set to TRUE
