ARM-based supercomputer tops speed rankings for the first time

ARM-based supercomputer tops speed rankings for the first time

Riken and Fujitsu started developing the system in 2014, working closely with ARM to design the A64FX processor.

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

Fugaku is now being used for coronavirus research purposes but will be used for a range of other endeavors starting in April of next year.

The computer has already been put to work, fighting the coronavirus pandemic. The supercomputer will be used in discovering new drugs, developing high-performance materials and predicting weather and global warming. It has 158,976 of these 48-core processors, meaning there is a mind boggling 7,299,072 processor cores powering the Fugaku supercomputer.

A Riken-developed forerunner to the Fugaku has held the title of world's fastest supercomputer, but in recent years the race to develop the powerful machines has been dominated by the United States and China.

Fujitsu in the blog post announced that this is the first time a supercomputer topped the major rankings simultaneously. ARM processors are simpler and more power-efficient than other types, which is why they're often used in mobile devices where heat and power draw needs to be minimised. It has dived right up to the top of the world's fastest supercomputer list and absolutely dominated - all without the help of dedicated GPUs.

Battling will level up your Pokemon, letting you equip a number of new moves, which can be adapted for your playstyle. It will come to Nintendo Switch and mobile devices (with cross-play), and will be released as a free-to-start game.

The leading-edge technology developed for Fugaku will hopefully "contribute to major advances on hard social challenges such as Covid-19", Satoshi Matsuoka, director of the Riken Center for Computational Science, said in a statement.

Against this backdrop, the creators of Fugaku aimed to make the world's only easy-to-use supercomputer.

Fugaku also took the top spots in three other categories, measuring performance in computational methods for industrial use, artificial intelligence applications, and big data analytics.

The new Fugaku supercomputer takes a hell of amount of power to run, with 28 MegaWatts requried - meanwhile, the Summit uses 10 MegaWatts of power.

Japanese supercomputer Fugaku has taken the top spot in the list of 500 most powerful supercomputers in the world. A trial version of Fugaku placed No. 1 in the world for energy efficiency among supercomputers last autumn.

Moreover, Fugaku is the first Japanese supercomputer in nine years to get the first spot in Top 500 list.
