Wang Litao read the numbers on his computer screen and sat back, delighted.

The researcher, who was studying the damage Xiluodu Dam could withstand in an earthquake, had waited a month for the outcome of his team's complex simulations - but after entering his equation into Tianhe-1A, his results took just one hour.

Using the fastest supercomputer in the world, experts like Wang at the China Institute of Water Resources and Hydropower Research (IWHR) can help ensure the hydroelectric dam is stronger and safer for the millions who live along Jinsha River.

"The process has been shortened significantly allowing us to offer and analyze more solutions in the same amount of time," said Wang. "We can offer solutions faster to improve safety."

The dam is one of thousands of projects that will benefit from Tianhe-1A (named after the Milky Way), from research in geology, meteorology and medicine, to commercial design, construction and manufacturing.

"It could even save people's lives," said Wang, who explained that, in a landslide, the supercomputer could calculate where reinforcements are needed and what areas should be evacuated.

Xiluodu Dam, which is being constructed on Southwest China's Sichuan-Yunnan provincial boundary, is a key part of ambitious plans to build China's second largest hydropower plant. Once in operation, it will generate 12,600 megawatts of electricity.

As the area is prone to earthquakes, however, engineers must ensure it can survive a major eruption. If not, the water in its reservoir will flood every nearby city and village.

"What's worse, a flood from the upper reaches could even lead to the bursting of the Three Gorges Dam," said Wang, threatening the lives and property of 400 million inhabitants along the Yangtze.


"To avoid this disaster, we need to build a safer dam," he added.

The large capacity of Tianhe-1A - 2.57 petaflops, or quadrillion calculations per second - allows researchers to solve equations with far more variables, making their measurement more accurate.

Even without testing the supercomputer to the full, Wang was able to use a program that answered an equation with 500,000 unknown numbers.

Developed by the National University of Defense Technology (NUDT) in Hunan's provincial capital, Changsha, Tianhe-1A is also a boon for big business.

As in the case of Xiluodu, experts say the machine will help workers in commercial research and development departments find ways to improve the precision and manufacture of products, giving them a greater competitive edge.

Tianjin Motor Dies Co Ltd, which designs and manufactures car body panels and large stamping parts, is the largest of its kind in China and sells to auto giants like General Motors, Ford and BMW.

After employing Tianhe-1A to simulate its stamping process, "we expect to raise our market share" and "make the transition from offering low-end to the high-end products", explained Chen Huibin, one of Tianjin Motor Dies' experts in computer-aided engineering.

Thanks to the simulation, the company will save at least 450,000 yuan (S$88,245), or 3 per cent of costs in producing automobile side panels.

"It's a large saving," said Chen, "because our profit margins are only about 20-per cent profit."

Hu Qingfeng, deputy chief designer of Tianhe-1A, which is based at the National Supercomputer Center in Tianjin, said the supercomputer will also speed up manufacture of aircraft's core units using Chinese intellectual property.

Engineers can simulate wind tunnel trials and study the combustion process inside aircraft engines.

  1. Young's Literal Translation - Here is the wisdom! He who is having the understanding,
    let him count the number of the beast, for the number of a man it is, and its number
    is six hundred and sixty six.

    I am a prophet of the bible.
    Have an ear... the hour is here... like a thief in the night.
    The number is perfect. The signature of God.
    I was born 75 years to the day after Earthquake No. 333
    caused by Nikola Tesla,
    or I would have never been told.
    My social security# is six hundred and sixty-six.
    My Federal E.I.N. for Insight, llc. ends 666.
    I have counted the number of the beast,
    and with insight I calculate the number Tesla's Trinity.
    I bring proof from God by solving the riddle of Nikola Tesla.
    Nikola Tesla caused the 1899 Cape Yakataga and Yakutat bay earthquakes,
    with The Knob Hill Apparatus from his Colorado Springs lab.
    That is why he spent his last ten years and died in Room #3327.
    3h03m27s on September 3, 1899.

    A second divisible by 3,
    in a minute divisible by 3,
    in an hour divisible by 3,
    on a day divisible by 3,
    in a month divisible by 3,
    in a year divisible by 3
    TIMES THREE.

    And for Christ's sake it was Earthquake Milne Shide No. 333

    "All repeated acts or operations I performed had to be divisible by three
    and if I missed I felt impelled to do it again,
    even if it took hours." -Nikola Tesla (After Causing Earthquakes)
    "If you only knew the magnificence of the 3, 6 & 9;

    then you would have a key to the universe."
    -Nikola Tesla

    Three plus three is six, plus three is nine.

  3. I have got changes. Have an ear... Tesla spent last ten years and died in Room #3327 because Earthquake Machine No. 3 was the Knob Hill Apparatus in Colorado Springs which caused the 27 day long 1899 Alaskan Earthquakes commencing on September 3, 1899 at 3h03m27s or 3:03:27 pm epicenter time. That was a year divisible by 3 times 3, a month divisible by 3 times 3, a day divisible by 3, in an hour divisible by 3, a minute divisible by 3, a second divisible by 3 times 3 times 3 days and for Christ's sake it was Earthquake Milne Shide No. 333 and lasted 3 times 3 times 3 days.
    This is from straight the USGS regarding the 1899 earthquakes at Yakutat Bay, Alaska.
    They lasted 27 days. September 3 to 29, 1899 and included four or five world-shaking disturbances and hundreds of minor shocks. During four weeks there was almost constant palpitation of this part of the earth's crust. The shocks were most severe on September 3, 10, and 23, and were great on the 15th, 17th, 26th, and 29th. On the 10th there were over 50 small shocks and two world-shaking disturbances. The greatest faulting took place on September 10. The greatest uplift that had ever been recorded in the history of the world took place on September 10, 1899.
