 ===== Notice =====
+**All is back to normal. Please submit jobs from linux1,2,3. Email techstaff@cs.uchicago.edu if you find that something is amiss.**
 The SLURM cluster will become unavailable starting 2017-08-22 for an upgrade. Normal service should resume on 2017-08-25. Please check back here for status updates.
@@ Line 7: / Line 9: @@
 We still run systems with Ubuntu 14.04 installed. As of right now these systems cannot submit jobs to the cluster. This is on purpose. The slurm version jump between 14.04 and 16.04 was so huge that this was unavoidable. This means you should prefer to use linux.cs.uchicago.edu or any CS machine that run Ubuntu 16.04.
+**2017-08-24**: Everything seems to be working as expected. Please start using the cluster again. Email techstaff@cs.uchicago.edu if something is wrong/unexpected/broken/etc.

-To better manage the cluster we have virtualized the job submission nodes and give them all resources of the hardware. So, the actual resources you can consume on any one node is:
-  * 14 Cores, 14 threads

 ===== Usage =====
 Below are some common examples. You should consult the [[http://slurm.schedmd.com/documentation.html|documentation]] of SLURM if you need further assistance.
+=== Default Quotas ===
+By default we set a job to be run on one CPU and allocate 100MB of RAM. If you require more than that you should specify what you need. Using the following options will do: ''%%--mem-per-cpu%%'', ''%%--nodes%%'', ''%%--ntasks%%''.
 === Exclusive access to a node ===

 === Sample script ===
 Make sure you create a directory in which to deposit the ''%%STDIN%%'', ''%%STDOUT%%'', ''%%STDERR%%'' files.
