Satoshi Matsuoka is leading Japan's Fugaku project, which aims to build one of the fastest and greenest supercomputers in the world. Matsuoka, head of the RIKEN Centre for Computational Science, was appointed to lead Fugaku in April 2018.

Fugaku is the successor to RIKEN's K supercomputer, which was the fastest in the world in 2011. The aim is for Fugaku to be 100 times faster, eventually reaching exascale performance. That is roughly seven times the speed rating of the most powerful system built to date.

Fugaku will involve integrating 150,000 microprocessors. The finished product will take up around 20 times as much space as Barcelona's Mare Nostrum supercomputer, currently ranked the 30th most powerful in the world.

One of the most striking features of the new machine is its energy efficiency, Matsuoka says. The computer's CPU chip is not only three times faster than the best Intel-made version available today, but will only use one third of the power, he says.
