China launches exascale supercomputer prototype

China has operationalised a prototype exascale computing machine, the next-generation supercomputer, according to the developers.

The computer prototype has been jointly developed by the National Research Center of Parallel Computer Engineering and Technology (NRCPC), the National Supercomputing Centre in Jinan, east China's Shandong Province and the Pilot National Laboratory for Marine Science and Technology (Qingdao).

The Sunway exascale computer prototype was put in operation yesterday and helps to execute a quintillion calculation per second.

"The Sunway exascale computer prototype is very much like a concept car that can run on road," Yang Meihong, director of the National Supercomputing Centre in Jinan said. "We expect to build the exascale computer in the second half of 2020 or the first half of 2021," Yang was quoted as saying by state run Xinhua news agency.

The NRCPC led the team that developed Sunway TaihuLight, crowned the world's fastest computer two years in a row at both the 2016 and 2017 International Supercomputing Conferences held in Frankfurt, Germany.

Supercomputers are changing people's life in fields such as weather forecast, calculation of ocean currents, financial data analysis, high-end equipment manufacturing, and car collision simulation, Pan Jingshan, deputy director of the National Supercomputing Centre in Jinan said.

Pan said the new-generation supercomputers will provide strong support to scientific research in more fields.

Another prototype exascale supercomputer Tianhe-3 passed the acceptance tests on July 22. Its final version is expected to come out in 2020.

The two prototypes marked a further step towards China's successful development of the next-generation supercomputer, the Xinhua report said.

Several countries including US and Japan are also speeding up the development of the exascale supercomputer, expecting to unveil it in as early as 2021.

India has unveiled supercomputer "Pratyush", meaning the sun at the Indian Institute of Tropical Meteorology (IITM), Pune in January this year.
