The World’s Most Powerful Computer

China builds the world’s most powerful computer.

The 93 petaflop Sunway TaihuLight is installed at the National Supercomputing Centre in Wuxi.

At its peak, the computer can perform around 93,000 trillion calculations per second.

It is twice as fast and three times as efficient as the previous leader Tianhe-2, also from China, said Top500.

Its main applications include advanced manufacturing, weather forecasting and big data analytics, wrote Jack Dongarra in a paper about the new machine.

It has more than 10.5 million locally-made processing cores and 40,960 nodes and runs on a Linux-based operating system.

For the first time since the list began, China has overtaken the US with 167 computers in the top 500 while the US has 165.

“As a computer scientist it’s difficult writing software that can take advantage of and control large numbers of computer cores,” said Professor Les Carr from the University of Southampton.

“This is why supercomputers are restricted to specialised applications – you need very specialised computing needs to take advantage of them.

“They are like extremely high-spec Grand Prix racing cars – they are fantastic for racing on circuits but they’re not great for travelling from London to Edinburgh.”
