How the world’s fastest supercomputer, Fujitsu’s K, saves on power and money

ExtremeTech: Tired of cell phones and Mobile World Congress? Grab a bit of supercomputing news here. Fujitsu shared some details on how it managed to keep its K supercomputer running so efficiently at ISSCC last week. The K is currently the highest-performing supercomputer in the world, with a maximum speed of 10.5PFLOPS and a total of 705,024 cores. Such systems are notoriously power hungry; power consumption is one of the major hurdles DARPA identified in its recent call to US researchers to reinvent computing.
