TOKYO -- The Fugaku supercomputer, developed by Fujitsu and Japan's national research institute Riken, has defended its title as the world's fastest supercomputer, beating competitors from China and the U.S.

Fugaku held the top spot on the TOP500 list by achieving a score of 442 petaflops, or quadrillions of floating point operations per second. In second place was IBM's Summit supercomputer, which scored just 148 petaflops. The ranking, compiled by an international panel of experts, is released every June and November.
