- 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
- Checking that $alps_client and its value exists in PBS_HOME/mom_priv/config, and if so:
- If on Cray or Cray ALPS simulator, then recreate the out-of-box Cray-specific custom resources and vnodes,
- As part of reverting resources, the PBS_HOME/server_priv/resourcedef file is removed.
- 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.
- As part of reverting hooks, all hooks, except built-in hooks, are disabled.
