Supercomputers and the environment: two subjects that are becoming linked more and more these days. Supercomputers are running algorithms to find solutions to climate change and the government has funded the creation of one supercomputer to be devoted solely to climate change. Now, it seems the world's supercomputers are competing to be the greenest, or at least the most efficient.
The Green500 supercomputer list has come out with its ranking of -- you guessed it -- the 500 greenest supercomputers. The computers were rated based on speed relative to power consumption. The number one computer located at the University of Tokyo, the Grape-DR, can manage an impressive 815.43 megaflops per watt.
For those who want the details, the Grape-DR is a (very messy) cluster powered by 128 Intel Core i7-920 processors and four bespoke accelerator chips.
The Grape-DR team believes they can improve their speed per watt by 50 percent by the end of the year.via Engadget
