Greenest Supercomputer Needs a Zip Tie or Ten

Paul Lilly

And the award for the world's most energy efficient supercomputer goes to... Grape-DR, a supercomputer taking residence in the Department of Information Science at the University of Tokyo.

Grape-DR led all others in the Little Green500 List of energy efficient supercomputers in June, putting out 815.43 MFLOPS/W. That was enough to top IBM's second place machine in Germany, which puts out 773.38 MFLOPS/W.

Helping the Grape-DR top the list are 64 Intel Core i7 920 processors, plus an accelerator chip that's able to pump out 200 gigaflops with the same amount of power it takes to run a lightbulb.

For all of its power and efficiency, however, the Grape-DR could use a little TCL in the cable management department, don't you think?
