TOKYO -- Frontier, a U.S.-built supercomputer, has dethroned Japan's Fugaku, developed by the Riken Institute and Fujitsu, as the world's fastest such device, according to a twice-yearly ranking published Monday, ending the Japanese machine's two-year reign.
With the U.S. and China forging ahead in computational performance, the Japanese government will begin a full-scale study into building a successor to Fugaku, which placed second.
