Supercomputer K shut down in ceremony
"K," once the world's fastest supercomputer, was turned off for the last time on Aug. 30, during a ceremony at a facility of the government-backed Riken research institute in Kobe's Chuo Ward.
K twice topped world rankings for the most powerful supercomputers in 2011, while it was still in development.
Named after the numeral "kei," as it can perform 10 quadrillion calculations per second, the machine was in full-scale operation for seven years, starting in September 2012. K will be removed and replaced with the "Fugaku" supercomputer, which is scheduled to enter service in around 2021. Fugaku's processing speed is expected to be 100 times faster than K's.
