Objective
This is to enhance PBS reporting of resources_used values, in particular, have MoM accumulate resources_used values that are set in a hook, whether builtin resource or custom resource.
Interface 1: For multi-node jobs, report accumulated resources_used values in accounting logs/qstat -f output, for those resources set in a hook.
- Visibility: Public
- Change Control: Stable
- Synopsis: Display accumulated resources_used values in accounting logs and qstat -f output, for resources that are set in an execjob_prologue, execjob_epilogue, or exechost_periodic hook.
- Details:
- Resources_used resources 'cput', 'mem', 'cpupercent' will continue to be aggregated and reported as before.
The additional resources that can be accumulated are those that are set in a hook, which can be a builtin resource (e.g vmem), or a custom resource.
Builtin resource: If a builtin resource is set in a hook, then any polling done (if any) by MoM for its value will automatically be discontinued. The hook then becomes in charge of updating the value.
- Custom resource
The resource value collected in mother superior mom is aggregated with each of the values obtained from the sister moms whose nodes are part of the job.
