A while back I was reading a computer arts magazine and there was mention about a piece of software called tyrany. This software was designed to split heavy tasks over many cpu's on a network. So if you where compiling a program or rendering animation you could use all the processing power of an entire network to process the task being performed. This is similiar to the Bryce Lightening Network rendering engine but not limited to the task or application. Needless to say I lost track of the magazine and even which one it was before I could find out more information.

Does anyone know of this software or of any software that allows the processor power of a network to be used together?
