Tracking Group IDs are added to batch jobs to be able to track them regardless if they escape the process tree.
Batch systems that use this feature are:
- Sun Grid Engine (SGE, now known as the Oracle Grid Engine)
- Condor-C batch system
Other batch systems are known to have the feature, but it doesn't seem to be used in (known) Grid deployments:
- LSF
- Torque/PBS
Why do we need this plugin?
Here is an example process tree on a PBS/Torque based cluster Worker Node. For illustration purposes all non-relative processes are removed from the tree:
init-+
├─pbs_mom
│ ├─bash
│ │ └─1337.stro.n /var/spool/pbs/mom_priv/jobs/1337.stro.nikhef.nl.SC
│ │ └─jobwrapper /opt/lcg/libexec/jobwrapper ./CREAM31337_jobWrapper.sh
│ │ └─CREAM31337_ -l ./CREAM31337_jobWrapper.sh
│ │ └─glexec /bin/bash payload.sh
