IBM/ETH ZURICH TO BUILD WATER-COOLED SUPERCOMPUTER.

Article Excerpt
In an effort to achieve energy-aware computing, the Swiss Federal Institute of Technology Zurich (ETH), and IBM (NYSE:IBM) have announced plans to build a first-of-a-kind water-cooled supercomputer that will directly repurpose excess heat for the university buildings. The innovative system, dubbed Aquasar, is expected to decrease the carbon footprint of the system by up to 85% and estimated to save up to 30 tons of CO2 per year, compared to a similar system using today's cooling technologies.(1)

Making computing systems and data centers energy-efficient is a staggering undertaking. In fact, up to 50% percent of an average air-cooled data center's carbon footprint or energy consumption today is not caused by computing but by powering the necessary cooling systems to keep the processors from overheating--a situation that is far from optimal when looking at energy efficiency from a holistic perspective.

"Energy is arguably the number one challenge humanity will be facing...
