Hi James,<br><br>Thanks for your prompt response and explaining me the history of Torque and its architecture. So pbs_server is resource manager that takes care of the resource provisioning, pbs_sched/Maui for scheduling the job and resource allocation and pbs_mom for monitoring the computer node.. right??<br>
<br>So I guess that qmgr is part of pbs_server to set up the queues. Now let's say for a cluster of 20 nodes, 5 different queues are specified based on different type of execution priorities. Can all nodes consume jobs from any of the queues or they are configured for specific queues?<br>
<br>And what happens when a job arrives at the pbs_server? Does pbs_sched/Maui get the status info from the pbs_server about the available resources, and based on a job's requirements put that into a specific queue? Does it also allocate a specific execution node for that particular job or the compute node reads the job from a certain queue? In this case, adding dynamic nodes is possible?<br>
<br>My thoughts pretty are disjointed but I would much appreciate the explanations..<br><br>Best Regards,<br>Omer<br><br><br><br><div class="gmail_quote">On Feb 19, 2008 5:37 PM, James J Coyle <<a href="mailto:jjc@iastate.edu">jjc@iastate.edu</a>> wrote:<br>

Torque even allows you to wriote your own pbs_sched scheduler, or use<br> one of the few that were made. I used a special scheduler for an SGI<br> Origin 2000.<br><br>> --===============1031051813==<br>> Content-Type: multipart/alternative;<br>
