TOKYO -- A government-backed supercomputer project looks to zip past dominant American and Chinese rivals to reclaim the top spot for Japan in international speed rankings due out this month.

Co-developed by Fujitsu and the Riken institute, the Fugaku has a theoretical peak speed of roughly 530 petaflops. This is equivalent to each of the world's 7 billion people performing one calculation per second nonstop for more than two years.
