• Visibility: Public
• Change Control: Stable
• Synopsis: Modifications to include initial MoM config settings for Cray.
  
• Standing of the interface : modified interface
  
• Details
  • if on real Cray or Cray ALPS simulator, then initialize the PBS_HOME/mom_priv/config to have these:

  • $vnodedef_additive 0

  • $alps_client /opt/cray/alps/default/bin/apbasilNote: If on Cray ALPS simulator use '$alps_client /opt/alps/apbasil.sh'.<path to ALPS API>

  • $usecp *:/home /home

Interface:  Scheduler.revert_to_defaults() 

...

• 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.
