Japan’s Fugaku loses title of world’s fastest supercomputer

Japan’s Fugaku supercomputer has lost its position as the world’s fastest in terms of computing speed, ranking second after topping the list in a biannual ranking for the past four consecutive times, its developer, the Institute of Research Riken.

Named after an alternative word for Mount Fuji, it lost top spot to the Frontier supercomputer at Oak Ridge National Laboratory in the United States, which is 2.5 times faster than Fugaku, Riken said, citing the results of the US-EU study. TOP500 project.

Fugaku also came second in a project known as HPL-AI, which ranks artificial intelligence ability.

However, Fugaku retained the top spot for the fifth consecutive time in TOP500’s high-performance conjugate gradient which focuses on industrial use, as well as Graph500’s list for big data analysis, according to Riken.

“It shows that Fugaku continues to be one of the world’s leading supercomputers in a field where competition and development are fierce,” said Satoshi Matsuoka, director of the institute’s Center for Computational Science in Kobe, Japan. Hyogo prefecture, which hosts Fugaku.

Jointly developed by Riken and Fujitsu Ltd., the supercomputer launched partial operations in April 2020 and full-scale operations in March 2021. Fugaku was used to visualize how droplets that could carry the coronavirus spread from the mouth and to help explore possible treatments for COVID -19.

Fugaku’s predecessor, the K supercomputer, was decommissioned in 2019.
