I am attempting to convert a computer lab into a Beowulf cluster at my school and i was wondering what live cd operating systems i should use for it.  Also what should I do with it other than the folding @home project?  I have received permission from the teacher in charge of that computer lab and the cluster will only exist for approximately an hour per day, depending on the length of setup.  The estimated power of the whole system would be approximately 100ghz.  Any help would be great, thanks!
