13.3.1 PBS Resource Manager Extensions
Resource manager extensions within PBS are used by setting the -W flag. To enable this flag, some versions of PBS must be rebuilt. TORQUE and recent OSCAR distributions come with the flag enabled by default. Most other versions do not. The required steps are documented in what follows:
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
> make
(backup current $PBS_HOMEDIR directory contents)
 |
$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 ...
