 +====== MOAB Scheduler ======
 +PBS Torque is used to schedule and run jobs on our cluster. Two PBS processes are required to run jobs. On the PBS server, the pbs_server process runs to accept your job and add it to the queue. It will also dispatch the job to the nodes to run under the pbs_mom process.
 +
 +
 +==== Useful MOAB Commands ====
 +1. [[https://docs.adaptivecomputing.com/maui/commands/showq.php|showq]] - Displays information about active, eligible, blocked, and/or recently completed jobs.
 +
 +2. [[https://docs.adaptivecomputing.com/maui/commands/showstart.php|showstart]] - Displays the estimated start time of a job based a number of analysis types.
 +
 +3. [[https://docs.adaptivecomputing.com/maui/commands/checkjob.php|checkjob]] - Allows end users to view the status of their own jobs.
 +
 +====Useful External Resources====
 +[[https://www.icer.msu.edu/sites/default/files/files/understand_job_scheduler_v2.pdf|MSU -Understand job scheduler and resource manager]] - Describes the batch queuing system and has some useful diagrams explaining the interrelationship between the scheduler and the server.
