Further you will see a countdown of how much longer the session will be activesomething like login2.stampede2.tacc.utexas.edu where a login node prefixes the stampede2.tacc.utexas.edu address. Otherwise you should see something like: c455-011.stampede2.tacc.utexas.edu where a computer number has prefixed the stampede2 address. Additionally, the "showq" command is available on head node, while it is not available within an idev node.
