Japan's Fugaku retains title as world's fastest supercomputer

TOKYO -- The Japanese-made Fugaku captured its fourth consecutive title as the world's fastest supercomputer on Tuesday, although a rival from the U.S. or China is poised to steal the crown as soon as next year.

The Fugaku, jointly developed by Fujitsu and Japan's Riken national research institute, attained a computing speed of 442 petaflops, or quadrillions of floating point operations per second, according to the supercomputer-ranking project TOP500. This is roughly triple the speed of the IBM-built Summit supercomputer, which clocked in at 148 petaflops.
