 ======Managing Jobs======
-=====Managing Jobs on the Cluster=====
-The above commands work well when you have not logged out of the cluster while running the job.  Because of the cluster's [[Hardware_Configuration|setup]], there are many nodes that could be running your job.  When you log in to the cluster, you are automatically sent to a particular node //econ7// through //econ18//.  This might not be the same node that is running your job. To get to a particular nod use
- <code>ssh econ7</code>
-And then to see processes that are running under your username in this node:
- <code>ps ux</code>
-======Renice-ing=====
-You can change how many CPU cycles are given to your job by using the command <code>renice</code>.  Once you know the process id, you can use the command:
- <code>renice -n <priority> -p <process id></code>
-to change the [[nice]]ness of your process.  If you are running a computationally intensive job, please set your job to a high niceness level, so that you don't monopolize cluster resources :)
 =====General Job Management=====
-Once you have a job running, you might want to change it's priority (<code>renice</code>) or stop it.  To check on the list of running jobs, use the command <code>top</code>.

-[[http://unixhelp.ed.ac.uk/CGI/man-cgi?top|Top]] is an interactive program that dynamically lists processes running on the server.  Pressing '?' will get you to a help page.  Pressing 'q' gets out of the help page, and also quits top altogether.

 Alternatively, press 'q' to stop top.  Then, type use the <code>kill</code> command.
