Cluster provisioning software, including alternatives such as Rocks
Rocks <http://www.rocksclusters.org http://www.rocksclusters.org> is used by CAC and Cornell’s Computer Sciences dept (with CU AD). We instead use warewulf, with torque and maui.

Screen and tmux
Terminal multiplexers can manage multiple shell instances, or "windows," at the same time within a single session. They allow the user to detach and reattach terminal sessions, leaving any shells and their subprocesses managed by the multiplexer while detached. And more than one user at a time can simultaneously connect to the same session.
