• • These lines should appear in PBS_HOME/mom_priv/config:
  •         $vnodedef_additive 0
  •         $alps_client <path to ALPS API>
  •         $usecp *:<Absolute path to /home directory>  <Absolute path to /home directory>
    
    Notes: $usecp setting above is used to enable local copy of job output of jobs that ran on compute nodes.
    $vnodedef_additive 0 will allow MoM to tell the server that there are vnodes missing, which the server will mark as stale.

• • PBS_HOME/sched_priv/sched_config will have 'vntype' in the resources line.

3) Server

• • 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

  • if on real Cray or Cray ALPS simulator, then initialize the PBS_HOME/mom_priv/config to have these:

  • $vnodedef_additive 0

  • $alps_client <path to ALPS API>

  •                $usecp *:<Absolute path to /home directory>  <Absolute path to /home directory>

  • If on a Cray or Cray ALPS simulator then perform below:
    • Enable Restore the default 'PBS_translate_mpp' hook by:
      • Copying PBS_EXEC/lib/python/altair/pbs_hooks/PBS_translate_mpp.HK to PBS_HOME/server_priv/hooks/PBS_translate_mpp.HK
        Then set enabled=true in PBS_HOME/server_priv/hooks/PBS_translate_mpp.HK
        • In this way, the shipped version (i.e. default version) of the hook will be in PBS_HOME for any PTL test to enable if desired.
