Interactive nodes are systems where you get a <code>bash</code> shell from which you can run your code. This mode of operation is conceptually similar to running your code on your own computer, the difference being that you have access to much more CPU and memory. To check out an interactive node, run the <code>big_machine</code> or <code>any_machine</code> command from your login shell. Before running these commands, you will want to be in a [[CommunityData:Tmux|<code>tmux</code>]] or <code>screen</code> session so that you can start your job, and log off without having to worry about your job getting terminated. | Interactive nodes are systems where you get a <code>bash</code> shell from which you can run your code.
