Tmux

The problem: When building code for the MI300A you may encounter quite long compilation times. In order to anyway being able to build large applications, you can deploy a tool called tmux.

When calling tmux from a shell it somewhat opens another shell within the first one. You can "leave" that shell by holding Ctrl and pressing b as well as pressing d afterwards (without Ctrl being held!). Actually this does not stop the shell but dispatch your terminal from said shell (which continues running "in the background", even if you log out from the system).

When you like to return to the shell still running "in the background", you can do so by means of the command tmux attach-session.

If you have multiple such sessions running "in the background" you can list them by means of the command tmux list-sessions. Use the id listed in the first column as argument to the -t flag in order to return to a specific one, e.g. tmux attach-session -t 2.

Further tips:

• Prepend your build command by nice -+19 to keep the login node responsive for interactive usage.
• In case you like to see output in the shell but redirect it to a file at the same time, use <your build command> |& tee <file>
• In case you encounter issues with doing so, in particular when using colorized output, prepending your command with the command unbuffer may provide a solution, i.e. do $> unbuffer <your build command>
