 # Running Jobs on Polaris

+
+***SLINGSHOT 11 Upgrade: The upgrade will take place in three phases, with each phase taking place during one of the normally scheduled maintenance periods. During this time, there will be an additional queue, `ss11`. This queue will contain compute nodes that have been upgraded to Slingshot 11. The compute nodes in the `prod` queue will contain the Slingshot 10 nodes. The number of nodes in the `prod` queue will dwindle with each maintenance until all computes nodes have been upgraded to Slingshot 11. Once all compute nodes have been upgraded, the `prod` queue will once again have 496 nodes and the `ss11` queue will be removed.***
+
+***ATTENTION: From October 16th through November 13th, the Polaris nodes will be upgraded in 'chunks' to Slingshot 11. This will affect the prod queue sizes. Please read about the changes to the queues below.***

 There are five production queues you can target in your qsub (`-q <queue name>`):

 **Note:** Jobs in the demand queue take priority over jobs in the preemptable queue.
 This means jobs in the preemptable queue may be preempted (killed without any warning) if there are jobs in the demand queue.
