[dailytech] Roadrunner Supercomputer sets speed record

Quote:
Not even a week after the new Roadrunner supercomputer was juiced up and put to work, scientists are hard at work trying to push the machine to its limits. Housed at the Los Alamos National Laboratory, the primary goal of the supercomputer is to model the safety of the United States' aging nuclear weapons stockpile. At over a certified petaflop, the machine renders calculations in a day that would take every person on Earth a calculator and 46 years to accomplish.
Quote:
The supercomputer's architecture is based on a hybrid node system. Each node contains two AMD Opteron dual-core and four PowerXCell 8i processers. The PowerXCell CPUs are derived from the same Cell processor used in the Sony Playstation 3 and act as computational accelerators for the Opterons.

So they are basically using graphics cards for accelerators for the CPU's...

Hook up 20,000 9800GX2's and see what you have then.
