• • The hook PBS_HOME/server_priv/hooks/PBS_translate_mpp.HK is enabled.
  • Based on what is returned by the ALPS inventory :
    • vnodes representing the compute nodes will get created
    • the Cray-specific custom resources (e.g. PBScraynid, PBScrayhost, etc) will get created in PBS_HOME/server_priv/resourcedef.
    • the appropriate Cray-specific custom resources will be added to the vnodes.
    • since the mom config $vnode_per_numa_node is unset by default, there will be no PBScrayseg attribute on the vnodes representing the compute nodes.
  • Server settings :
    • flatuid = true

    • scheduling = true

    • the default queue is workq workq

Interface:  MoM.__init__()

• resources and vnodes
  
  • As part of reverting resources, the PBS_HOME/server_priv/resourcedef file is removed.
    
    • If on Cray or Cray ALPS simulator, then recreate the out-of-box Cray-specific custom resources and vnodes,
      including the ones PBS creates from reading the ALPS inventory, by:
      • Checking that $alps_client and its value exists in PBS_HOME/mom_priv/config, and if so:
        • delete all the vnodes: qmgr -c "delete node @default"
        • add back the MoMs: qmgr -c "create n <MoM hostname>"
        • check until such time that the MoM node has actually been added and the node state is free
        • if successful, then
          
          • the resourcedef file and the vnodes would have reverted to the out-of-box Cray configuration.
        • If there is an error during one of the following:
          • checking if $alps_client is properly configured
          • deleting all vnodes
          • adding MoMs
          then raise an exception.
• hooks
  • As part of reverting hooks, all hooks, except built-in hooks, are disabled.
    
    • if on a Cray ALPS simulator, then enable the PBS_translate_mpp .HK hook.
    • If there is an error during enabling of the PBS_translate_mpp .HK hook, then raise an exception.
