At our local LUG (http://lugoj.org), we just had a presentation from one of our members who built an 8-node Beowulf cluster using RedHat. During her presentation (http://atlee.net/beowulf/), one of the topics that came up was the potential for a Knoppix-powered cluster.

Has anyone set one up? I've inherited much of her cluster hardware for experimentation and would like to see what I can come up with.
