For the first time in history, China has overtaken the United States in the number of supercomputers. Currently, China has a total of 202 of the world’s 500 fastest computers, up from 159 half a year ago. The number of US supercomputers has dropped to 144.
The world’s most powerful computer is located in China. The Sunway TaihuLight , at Wuxi can do 93 quadrillioncalculations per second. The fastest UScomputer,the Titan, is ranked fifth while Europe’s speediest computer is Switzerland’s Piz Daint, ranked third.
Supercomputers are machines that occupyentire buildings and use the combined power of thousands of processors. They are used to carry out special tasks that involve a huge number of calculations. Among them are weather forecasts and climate studies, as well as strategic tasks like nuclear weapons simulations.
Chinese supremacy in the world of supercomputing reflects the country’s investment in research and development. One-fifth of the money used on research and development around the world is spent in China.
On the other side, many Chinese systems have been created to earn money. Processing power is rented to other national and international companies.
For years the speed of supercomputers has steadily increased although since 2012 this increase has slowed down.

Singles Day is the biggest e-commerce day in the world. Organized by China’s Alibaba, shopping sales on November 11 hit a record $25 billion, 40% more than on Singles Day 2016. In contrast, Prime Day, organized by Amazonachieved only $1 billion in sales. During the Thanksgiving and Black Friday weekend of 2016 American online shoppers spent $5 billion.
Singles Day started out as an informal holiday in China, celebrating people who stayed single. Similiar to Valentine’s Day in the western world Singles Day took place on 11/11 . In 2009, Alibaba turned it into a shopping holiday and in the past 8 years, sales have steadilyincreased.
Although the event targets mostly Chinese customers, shoppers came from 220 countries. Over 80 brands took part in the event, with Nike and Xiaomi Corp. among the biggest winners. Household goods and electrical appliances were the most bought products, but customers soughtbargains for almost everything, ranging from cheap toilet paper to rice.
At its peak Alibaba’s computers handled 250 000 transactions per second, most of them coming in via mobile phones. In the weeks before the event was held, Alibaba had helped 600,000 companies upgrade their computer systems to make them fit for Singles Day.
The event was also turned into a gala in Shanghai where celebrities Nicole Kidman and tennis star Maria Sharapova counted down the seconds until the world’ largest sales event started.
Many critics of the event say that Singles Day is environmentallycontroversial. It creates an enormous amount of waste. According to Greepeace, 1 billion packages were delivered in the days that followed the event.
