Torque provides administrators the ability to run scripts before and/or after each job executes. With such a script, a site can prepare systems, perform node health checks, prepend and append text to output and error log files, cleanup systems, and so forth.
The following table shows which MOM runs which script. All scripts must be in the TORQUE_HOME/mom_priv/ directory and be available on every compute node. The "Mother Superior" is the pbs_mom on the first node allocated for a job. While it is technically a sister node, it is not a "Sister" for the purposes of the following table.
The initial working directory for each script is TORQUE_HOME/mom_priv/.

| presetup.prologue | Mother Superior | 8th argument | root | Readable and executable by root and NOT writable by anyone but root (e.g., -r-x-----) |
