World's Greenest Supercomputer Not the Fastest

Supercomputers are tasked with performing massive calculations that can't be practically done in any sort of reasonable time on regular computers. For that, supercomputers have special power and cooling needs, but as we can see from the Department of Information Science at the University of Tokyo, supercomputers can be green-minded too.

The Japanese supercomputer system, called Grape-DR, is ranked as the greenest supercomputer on the planet. Its performance over power is 815.43 MFLOPS per watt, besting the second place IBM's 773.38 MFLOPS per watt in Germany.

The Grape-DR is composed of 64 Core i7-920 microprocessors, and Asus motherboard, 18 GB of DDR3 memory, and a custom accelerator board.

The custom accelerator board, developed by a professor at the University of Tokyo, enhances performance of the Core i7-920 system by about five times, according to TechOn.

While the Grape-DR is the most energy efficient supercomputer in the world, it's not even near the fastest. Its total performance of 23.4 TFLOPS is below the 24.67 TFLOPS needed to crack the top 500 supercomputers in the world.

  • "I'm pretty sure that it can."

    but you dont have access to it, so it is all assumption sigh

  • I put a plant on mine, it is greener then all of them.

  • I'd be interested in finding out exactly could be done with one of those accelerator boards in a workstation running Windows or Linux. Wonder what it does exactly?

  • It may not be the fastest, but looking at the specs, at least it could very well play crysis! :P

    thoses numbers seem to be too low, you can beat that with bunch of graphic cards like TESLA packages
