The execution directory for each script is TORQUE_HOME/mom_priv/.
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. "Mother Superior," as referenced in the following table, is the pbs_mom on the first node allocated, and the term "Sisters" refers to pbs_moms, although note that a Mother Superior is also a sister node.
The execution directory for each script is TORQUE_HOME/mom_priv/.
