Japan's "Fugaku" Supercomputer Rated World's Most Powerful

Science Society Technology

Tokyo, June 23 (Jiji Press)--Riken said Tuesday that "Fugaku," being developed jointly by the Japanese government-linked research institute and other entities including Fujitsu Ltd. <6702>, has been declared overwhelmingly the most powerful supercomputer in the TOP500 and three other global ranking categories.

It is the first time for a Japanese supercomputer to rank first on the TOP500 list since Riken's K computer claimed the No. 1 spot in June 2011 and November the same year.

Fugaku, installed at the Riken Center for Computational Science (R-CCS) in the western Japan city of Kobe, achieved around 416 petaflops, or quadrillions of floating-point operations per second, some 2.8 times more than roughly 149 petaflops for the second-ranking Summit supercomputer in the United States.

The calculations were conducted by approximately 95.6 pct of Fugaku's some 159,000 central processing units mounted on 432 computer racks. The machine is expected to achieve even faster computing speeds through future software improvement, according to the Japanese team.

The Japanese supercomputer also ranked top in the High Performance Conjugate Gradients benchmark, which measures calculation speed for computer programs such as those for commercial use, the HPL-AI benchmark, measuring computing performance for artificial intelligence, and the Graph500 rating of a computer's ability to analyze graphs, important for big data processing.
