Hardware, Embedded Systems Currently the fastest supercomputer in Europe, the Jugene can process one trillion operations per second, has 294,912 cores that comprise 32-bit PowerPC 450 processors at 850 MHz, has 144 terabytes of RAM, has a bandwidth of 5.1 gigabyte/second with a mere 160 nanosecond latency, and is one heck of a machine mounted on 72 racks. I wouldn't mind having one of these in my basement regardless of the power bill. For pictures and more information, read the linked article.

Not for this application I'm guessing. When dealing with these kinds of systems, you should remember that moving data around and it's latency is probably the most important performance bottleneck, the processor is probably a whole lot less of an issue. Also did you see in the pictures how tightly packed they are ? Do you know how much heat faster powered processors would generate ?:
