China’s Progress in Exascale Computing


Exascale computing (quicker than 1 billion billion operations per second) is well accepted as the next crown of supercomputing.

Its research and development (R&D) plan is the forefront of creation and competition of high-end information technology. Both the US and Japan have drawn up their exascale computing plan for the production of an exascale computer by 2020 or later.

Mil.huanqiu.com says in its report “Breaking boycott! Tianhe 3 exascale computing prototype has passed acceptance test” that China drew up a plan in 2016 on 2-phase development of exascale computers. The first phase focuses on the research of key technology for exascale computer with the production of 3 prototypes of exascale computer while the second phase will be the research and development of exascale computers.

Lead by the National University of Defense Technology, China has developed Tianhe 3 exascale prototype system and has it passed acceptance test on July 22. China has thus begun the second phase of essential R&D of Tianhe 3 exascale computer 200 times quicker and with memory capacity 100 times larger than Tianhe 1.

Since 2015, the US has banned the export of supercomputer CPU to China to prevent Tianhe from maintaining its no. one ranking among supercomputers in the world. However, China is entirely able to obtain crown technology on its own. It has now succeeded in mastery of five major homegrown core technologies of Tianhe series of supercomputers: the CPU, accelerating CPU, the interlink communication router and interlink interface chips and the operation system (the software).

At present, the Tianhe 3 exascale prototype system has achieved 4 major homegrown creations, i.e. the three chips of the “Maichang” multi-core processor (Matrix-2000+), interlinking interface chip and router chip, 4 kinds of calculation, storage and services knobs, more than 10 PCP circuit boards, various new-type hardware subsystems and various software subsystems.

That will enable Tianhe 3 exascale computer to do lots of jobs such as Large-scale space and aviation data wind tunnel, weather forecasting, climate research, oil and gas exploration, excessively large scale calculation and simulation for life scientific research, the development of a new generation of artificial intelligence, etc.

Those, including the exascale supercomputer are indeed crown jewels of technology. Can China steal those crown jewels from the US? Sorry, the US is also developing such technologies but cannot be sure to achieve results before China. Can China steal from the US what the US does not have?

Therefore, to stop China obtaining those crown jewels no one in the world has now, US only and last resort is to start a trade war with China.

    China has three contenders in the exascale computing race. Three prototypes are built in Phase 1 to evaluate the feasibility of different architectures. They must solve the complex power and cooling and interconnection problems. It looks like phase 1 is going well. It signals the start of Phase 2 – the implementation of the best architecture to build the world’s first exascale computer.

    The US cancelled funding for the prototyping phase of exascale projects. The US is already behind China and Japan’s efforts and their risk will be increased by trying to go directly into building an exascale computer.

    Less than a decade ago, China was playing catch up to new technologies of US and Russia. Now the US and Russia is mystified by China’s phenomena rise, achievements and progress.

    Trump said ‘Trade wars are good and easy to win’, President Xi is proving that Trump is wrong on both accounts. One – Trump’s ‘easy to win’ is contradicted by being compelled to subsidise US farmers to the tune of $12 billion, which his opponents will use to haunt him in the next election. US Senator Ben Sasse warned that Trump’s protectionist gambit is ‘going to make it 1929 again’ – meaning stock market crash and great depression, but of course Trump will still enjoy his billionaire status. Two – China is export reliant, but so are China’s strong economic neighbourhood of Japan, Sth Korea and Singapore that trade more with China than anyone else, in fact Asian countries wants to see a strong China’s economic growth.

    America under Trump will have nightmares given the fact that China has many non trade arsenals to belt Americans. Example, China can play hardball and give facebook the boot, in other words asking Mark Zuckerberg to get lost. Recently, China played the Taiwan card as a counter against the US scoundrel behaviour by forcing US airlines to comply with instructions to describe Taiwan as part of China on their websites. Financial institutions like American express, Citibank, Goldman Sachs, etc also protected themselves by scrubbing any suggestions that China and Taiwan were not part of the same nation. China has many other trump cards to prove that Trump is dumb. America under Trump is dangerous, he is no shrewd head.
