<h1>14.7 Problems with Individual Jobs</h1>
<p>To determine why a particular job will not start, there are several commands which can be helpful.</p>

<p>Checkjob will evaluate the ability of a job to start immediately. Tests include resource access, node state, job constraints (ie, startdate, taskspernode,QOS, etc). Additionally, command line flags may be specified to provide further information.</p>
<p>-l <POLICYLEVEL> // evaluate impact of throttling policies on job feasibility<br>
-n <NODENAME> // evaluate resource access on specific node<br>
-r <RESERVATION_LIST> // evaluate access to specified reservations</p>
<p><b><a href="commands/checknode.html">checknode</a></b></p>

<p><b><a href="commands/diagnosequeue.html">diagnose -q</a></b></p>
