Japanese Super-Computer Officially Most Powerful Computer Ever

Sun Jun 28 2020

Fugaku has just taken the top spot for the worlds most powerful supercomputer

Japanese Super-Computer Fugaku has not only taken the top spot in the listing of the worlds most powerful computer, but it also swept the board, being the first computer in history to take the top spot in all four ranking categories.


Developed jointly between Fujitsu and the Japanese Research Institute Riken, Fugaku features chip technology built by ARM Ltd as well as Fujitsu’s cutting edge 48-core A64FX system-on-chip.

It’s capable of carrying out over 415.5 quadrillion computations a second (petaflops) as well as testing thousands of substances week in the ongoing search for a cure to the coronavirus.


The super-computer has currently been put to use on experimental COVID-19 research which includes complex simulations of how SARS-Cov-2 spreads as well as the effectiveness of Japans contact-tracing app.

I very much hope that Fugaku will show itself to be highly effective in real-world applications and will help to realise Society 5.0.

When put through the High Performance Linpack (HPL) test, Fugaku was proven to be over 2.8 times faster than it’s nearest competitor, the American Summit super-computer and previous record holder.

Impressively though, Fugaku, which also features 150,000 high-performance processing units, took top positions in HPL-AI, Graph 500 and HPCH, the first time a super-computer has claimed top spots in all four tests.

It’s also the first Japanese super-computer to hold the no.1 spot in over nine years in a list that includes 225 super-computers from China, 114 from the USA and 30 from Japan. 


Last month, Microsoft announced that they’d built a super-computer for OpenAI.

This new super-computer features 285,000 processor cores, 10,000 GPUs and can offer 400 gigabits per second of network connectivity for each GPU server.
