The world's top 25 most energy-saving supercomputer unveiled

The world's most powerful computer is also the right of the green? This is in 2007 the world's top supercomputers behind a fundamental question. The ranking is based on floating-point operations per second performance and energy consumption ratio, that is, "millions of floating-point operations per second / per watt."

Virginia Tech's editor of the Green 500 list of supercomputers to people took note of the supercomputer designers should pay more attention to energy consumption, and not just concerned about the speed or computing power. The top 25 energy-efficient supercomputers are:
