 ### Running commands in parallel with tmux
 
 [tmux](https://github.com/tmux/tmux/wiki) can be used to run commands on multiple compute instances at the same time. See the [Running commands in parallel with tmux](01-prerequisites.md#running-commands-in-parallel-with-tmux) section in the Prerequisites lab.
