This project is interesting, given that it's open source and you can dynamically add or remove units. As far as power goes, crank down the clock speeds and any processor is going to run cooler. arm is also well known for taking less power. But about the whole changing your basic architecture, consider Tilera: http://www.itjungle.com/tlb/tlb082107-story02.html http://www.itjungle.com/tlb/tlb082107-story02.html http://www.theregister.co.uk/2008/09/23/tilera_cpu_upgrade/ http://www.theregister.co.uk/2008/09/23/tilera_cpu_upgrade/ And it runs linux! ;)Granted it's closed and probably costs a bazillion, but the big guys haven't exactly missed out on the memory bus being a bottleneck.
