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)
