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 ...
