University of Wisconsin-Madison engineers have designed and built the world’s most energy-efficient supercomputer, earning the top ranking on an important benchmark called the Green Graph 500 list.

Topping the Green Graph 500 list is an achievement that establishes UW-Madison as a major player in the field of high-performance computing. The certification builds on established practices from the U.S. Environmental Protection Agency Energy Star, and is backed by a steering committee composed of more than 50 international experts from academia, industry and national laboratories.
