Supercomputing in Japan

The Earth Simulator in Yokohama was the world's fastest supercomputer in 2004, but 7 years later the K computer in Kobe became over 60 times faster.

Japan operates a number of centers for supercomputing which hold world records in speed, with the K computer being the world's fastest from June 2011 to June 2012,[1][2][3] and Fugaku holding the lead from June 2020 until June 2022.

The K computer's performance was impressive, according to professor Jack Dongarra who maintains the TOP500 list of supercomputers, and it surpassed its next 5 competitors combined.[1] The K computer cost US$10 million a year to operate.[1]
