Japan’s Fugaku Supercomputer Becomes Fastest Supercomputer Beating IBM Summit

Fugaku (1)

A Japanese Supercomputer Fugaku has been now declared as the fastest supercomputer on earth. Fugaku is the brainchild of the Riken and Fujitsu.

The Japanese supercomputer has managed to beat the long-reigning champion IBM Summit to become the fastest supercomputer in the earth. It was named as the top supercomputer by the International Supercomputing Conference which published the list of Top 500 list of world’s fastest supercomputers. With Fugaku winning, the title of the fastest supercomputer has been brought back to the country of Japan. Before this, the supercomputer ‘K Computer’ developed by RIKEN bagged the title nine years ago.


Fujitsu briefed about Fugaku’s performance and told that Fugaku’s Linpack performance is close to 40 times more than the K Computer and twice as fast as the IBM Summit which topped the rankings in Top 500 list in November last year.

The Fugaku is based on the ARM architecture and has been specifically optimized for supercomputing applications like artificial intelligence and technical and scientific simulations. There are over 150,000 high-performance A64FX CPU’s which are interconnected with the Tofu D Interconnect high-speed network. This makes the supercomputer incredibly powerful. The A64FX is extremely energy efficient by consuming only 30 Megawatts at full power.

The company also revealed that Fugaku’s peak performance is at 537 PetaFLOPS i.e. 5*10 to the power of 17 floating-point operations per second. According to the company, the supercomputer is named after the highest mountain of Japan, Mount Fuji. Interestingly, the first few racks of Fugaku supercomputer was installed in RIKEN back in December 2019. The supercomputer comprises of 400 racks. Fugaku is termed to be 100 times more powerful than RIKEN, its predecessor.


The team behind the supercomputer Fugaku has plans to extend the scope of the machine. The plans that have been laid down as of now is set to deliver efficient energy, predicting weather and environmental disasters along with developing materials for next-gen manufacturing among others.

However, the supercomputer Fugaku is already involved in various Research and Development processes including fighting the novel coronavirus pandemic along with its predecessor RIKEN. This also includes other projects.
