Logging In
You will need to use SSH (Secure Shell) in order to access the cluster. Windows users can use PuTTY or Cygwin. MacOS users can use the built-in Terminal application.

Now you have moved from the login node to a one of the compute nodes on the cluster. While simple things like editing a file or making new folders can be done on a login node, they can also be done on a compute node, and as you run more complicated jobs on Insomnia, some things simply will not work unless you are first on a compute node.
