Japan supercomputer is world's fastest
Japan Today -- Jun 23
Japan's Fugaku supercomputer, built with government backing and used in the fight against coronavirus, is now ranked as the world's fastest, its developers announced Monday.

It snatched the top spot on the Top500, a site that has tracked the evolution of computer processing power for more than two decades, said the Riken scientific research centre.

The list is produced twice a year and rates supercomputers based on speed in a benchmark test set by experts from Germany and the U.S.

Fugaku was jointly developed by Riken and the firm Fujitsu and has a speed of roughly 415.53 petaflops -- 2.8 times faster than the second-ranked U.S. Summit supercomputer's 148.6 petaflops.

A supercomputer is more than 1,000 times faster than a regular computer, according to Riken.

Summit had topped the last four rankings over the previous two years.

Fugaku, meaning Mount Fuji in Japanese, has been under development for six years and is expected to start full-time operation from April 2021.

But it is already being put to work on the coronavirus crisis, running simulations on how droplets would spread on office spaces with partitions installed or packed trains with windows open.

神戸市の理化学研究所が開発しているスーパーコンピューター「富岳」が計算速度などで世界ランキング1位を獲得しました。  富岳は1秒間に1京回の計算が可能だったスーパーコンピューター「京」の後継機です。構想から10年かけて開発され、京の100倍の計算速度、スマートフォン2000万台分の性能を持っています。22日にスパコンの世界ランキングが発表され、計算速度やグラフ解析の性能など4つの部門で富岳が1位を獲得しました。本格的な運用は来年度から始まる予定ですが、すでに一部を前倒しして動かし、新型コロナウイルスに有効な治療薬を探す研究や飛沫(ひまつ)感染のシミュレーションなどに活用しているということです。
