The Japanese supercomputer Fugaku, jointly developed by Fujitsu and Japan’s Riken Research Institute, was rated as the fastest computer in the world in an independent survey. This marked the return of Japanese supercomputers to the top of the list after nine years, beating the supercomputers of the United States and China. This is also the first time a supercomputer based on an ARM processor has become the top of the benchmark. Fugaku further secured the first place in other major rankings using different parameters on the test supercomputer.

Supercomputers are used to perform highly complex tasks, such as quantum mechanics, weather forecasting, space exploration, etc. These tasks require high-performance specialized calculations.

Fugaku ranked first in the TOP500 ranking

On Monday, Fugaku appeared on the spot in the biennial TOP500 publication. The last time Japan’s supercomputer won the championship was in 2011, and it was also jointly developed by Riken and Fujitsu. Supercomputers are called “K computers”.

This year’s TOP500 is followed by two supercomputers from the United States and two supercomputers from China. Overall, the United States has four supercomputers in the top ten of the TOP500.

Fugaku is powered by Fujitsu’s 48-core A64FX SoC and is 2.8 times faster than IBM’s Summit supercomputer, which ranked second in this year’s Top500 list. Japanese supercomputers also achieved the highest rankings in other publications such as Graph 500, HPL-AI and HPCG.

Fujitsu announced in a blog post that this is the first time a supercomputer has been ranked among the top of the main rankings at the same time.

Nakatoshi Matsuoka, director of the RIKEN Research Institute, said: [Fugaku] It will help make significant progress on tough social challenges such as COVID-19. “

The developer also announced that Fugaku will be fully operational in the next fiscal year.
