GPUs Boost Supercomputers' Energy Efficiency

Supercomputers that mix CPUs with graphics processors made their mark on the Green500 list of top energy-efficient supercomputers released on Wednesday.

Eight of the world's greenest supercomputers combined specialized accelerators like GPUs with CPUs to boost performance and make supercomputers more power efficient, according to the Green500 list, which is released twice a year. The list was released by the same group that compiles the Top500 list.

Supercomputers with accelerators are three times more energy efficient than their non-accelerated counterparts on the list, according to Wu Feng, associate professor of electrical and computer engineering at Virginia Polytechnic Institute and State University's college of engineering. LINK
