Inside Grape-DR there are 64 Intel Core i7-920 processors and 4 Grape-DR accelerator chips. It would be interesting to note that each accelerator chip is able to reach 200 gigaflops with only 50-watts of power.

The supercomputer was developed by Professor Kei Hiraki of the University of Tokyo together with a research team led by Jyunichiro Makino, professor at the National Astronomical Observatory of Japan.

Those who like numbers, the supercomputer's performance per unit power consumption is 815.43 MFLOPS/W. For comparison, IBM's supercomputer registers 773.38 MFLOPS/W, reports Technabob.

In the June edition of the "Little Green500 List," Grape-DR featured 1st among the 500 environmentally-friendly supercomputers. Currently the machine ranks 500th in the Top500 list of the fastest supercomputers on the planet.
