13.3.1 PBS RM Extensions

RM extensions within PBS are utilized by using the '-W' flag. To enable this flag, some versions of PBS must be rebuilt.(NOTE: TORQUE and recent OSCAR distributions come with the flag enabled by default. Most other versions do not.)
The required steps are documented below.

> qterm -t quick #shutdown PBS server (cd to the directory from which you executed the PBS 'configure' at install time) make distclean ./configure <WITH OPTIONS>

create addparam script
(chmod +x addparam)

addparam x S

Note In Maui 3.2.x, only the 'x' parameter needs to be added.

make

(backup current $PBS_HOMEDIR directory contents, NOTE: $PBS_HOMEDIR defaults to /usr/spool/PBS)

> make install

(restore old $PBS_HOMEDIR directory contents)

> pbs_server # restart PBS server

A job's QOS level can then be specified using qsub's '-W' flag, i.e., qsub -W x=iQOS:hi -l nodes=4 ...

(addparam script follows)

#!/bin/sh
#script: addparam
#usage: addparam $Parameter [S|L]
