Japan’s Fugaku supercomputer, built with government backing and used in the fight against coronavirus, is now ranked as the world’s fastest, its developers announced Monday.

It snatched the top spot on the Top500, a site that has tracked the evolution of computer processing power for more than two decades, said the Riken scientific research centre.

The list is produced twice a year and rates supercomputers based on speed in a benchmark test set by experts from Germany and the US.

Fugaku was jointly developed by Riken and the firm Fujitsu and has a speed of roughly 415.53 petaflops — 2.8 times faster than the second-ranked US Summit supercomputer’s 148.6 petaflops.

A supercomputer is more than 1,000 times faster than a regular computer, according to Riken.

Summit had topped the last four rankings over the previous two years.

Fugaku, meaning Mount Fuji in Japanese, has been under development for six years and is expected to start full-time operation from April 2021.
