<h1>13.3.1 PBS RM Extensions</h1>RM extensions within PBS are utilized by using the '<b>-W</b>' flag. To enable this flag, some versions of PBS must be rebuilt.(NOTE: <a href="http://docs.adaptivecomputing.com/torque">TORQUE</a> and recent OSCAR distributions come with the flag enabled by default. Most other versions do not.)<br>
The required steps are documented below.
<p><b>> qterm -t quick #shutdown PBS server</b> (cd to the directory from which you executed the PBS 'configure' at install time) <b>make distclean</b> <b>./configure <WITH OPTIONS></b></p>
<p><b>create <a href="13.3.1pbsrmextensions.html#addparam">addparam</a> script</b><br>
(chmod +x addparam)</p>
<p><b>addparam x S</b><br></p>
<table class="note">
<tbody>
<tr>
<td class="noteIMG"><img src="note.png" title="Note" alt="Note"></td>
<td class="noteDetail">In Maui 3.2.x, only the '<b>x</b>' parameter needs to be added.</td>
</tr>
</tbody>

<p><b>make</b></p>
<p>(backup current $PBS_HOMEDIR directory contents, NOTE: $PBS_HOMEDIR defaults to /usr/spool/PBS)</p>
<p><b>> make install</b></p>
<p>(restore old $PBS_HOMEDIR directory contents)</p>
<p><b>> pbs_server # restart PBS server</b></p>
<p>A job's QOS level can then be specified using qsub's '-W' flag, i.e., qsub -W x=iQOS:hi -l nodes=4 ...<br></p>
