[http://slurm.schedmd.com/ SLURM] is a queue management system and stands for Simple Linux Utility for Resource Management. SLURM was developed at the Lawrence Livermore National Lab and currently runs some of the largest compute clusters in the world. SLURM is the primary job manager on Cheaha (BigGreen- new hardware) while GridEngine continues to be the job manager on the old hardware.
The Slurm documentation has moved to the new documentation site at https://uabrc.github.io.


SLURM is similar in many ways to GridEngine or most other queue systems. You write a batch script then submit it to the queue manager (scheduler). The queue manager then schedules your job to run on the queue (or '''partition''' in SLURM parlance) that you designate. Below we will provide an outline of how to submit jobs to SLURM, how SLURM decides when to schedule your job and how to monitor progress.

=== General SLURM Documentation ===
The primary source for documentation on SLURM usage and commands can be found at the [http://slurm.schedmd.com/ SLURM] site. If you Google for SLURM questions, you'll often see the Lawrence Livermore pages as the top hits, but these tend to be outdated.
 
A great way to get details on the SLURM commands is the man pages available from the Cheaha cluster. For example, if you type the following command:
 
<pre>
man sbatch
</pre>
you'll get the manual page for the sbatch command.
