Our lab has invested in UTK's Newton cluster. Much of the info below is taken from various pages of cluster documentation
ssh username@newton0.usg.utk.edu
Newton has limited storage in each user's ~ directory. You can request project-specific storage at http://newton.utk.edu/bin/view/Main/StorageApplication. There is also scratch storage. See more here
If you want to run an interactive job (i.e., interact with a command line program), use the command qrsh
qstat for status of your jobs
qstat -u \* for all jobs on the cluster
qstat -g c for a list of available queues
