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

 +===== Where to begin =====
 +SLURM is a set of command line utilities that can be accessed via the command line from **most** any computer science system you can login to. Using our main shell servers (linux.cs.uchicago.edu) is expected to be our most common use case, so you should start there.

 +== Performance is slow ==
 +This is expected. The maximum speed this server will ever be able to achieve is 1Gb/s because of its single 1G ethernet uplink. If this cluster gains in popularity we plan on upgrading the network and storage server.

When the interactive session starts, you will notice that you are no longer on a login node, but rather one of the compute nodes dedicated to this queue. The ''%%--pty%%'' option allows the session to act like a standard terminal. will start a command line shell (''%%/bin/bash%%'') on the 'general' queue with 500 MB of RAM for 6 hours; 1 core on 1 node is assumed as these parameters (''%%-n 1 -N 1%%'') were left out.
