    China surpassing U.S. with 54.9 petaflop supercomputer - Computerworld

    Computerworld - China has produced a supercomputer capable of 54.9 petaflops, more than twice the speed of any system in the U.S., according to a U.S. researcher who was in China last week and learned the details.

    China's latest system was built with Intel chips, but includes indigenously produced Chinese technologies as well. The Chinese government spent about $290 million on it.


    Today, the world's fastest supercomputer is at Oak Ridge National Laboratory in Tennessee. The Cray system was running at nearly 18 petaflops, according to last November's biannual Top 500 list. That list will be updated in mid-June.

    With its new supercomputer, China is raising the stakes in supercomputing for the U.S., as well as for Japan and Europe. It is showing a willingness to push for leadership in HPC and the race to develop the next generation of systems, exascale.

    Jack Dongarra, a professor of computer science at the University of Tennessee and one of the academic leaders of the Top 500 supercomputing list, posted a detailed description late Sunday of China's latest system ( report PDF ) from his trip to China. His findings are based on a briefing at an HPC conference May 28-29 in Changsha by a Chinese official from the National University of Defense Technology (NUDT).

    HPC Wire reported on the new system this weekend.

    China's latest large system is the successor to its Tianhe-1A supercomputer, which won the global title as the world's fastest in November 2010. President Obama made note of China's supercomputing accomplishment in his state of the union speech in January, 2011, where he said the U.S. was facing another "Sputnik moment" in wide range of technologies.

    China's latest supercomputer, called Tianhe-2 or Milkyway-2, has 32,000 multicore Intel Xeon Ivy Bridge chips, and 48,000 Xeon Phi chips, a co-processor based on Intel's MIC (Many Integrated Core) architecture.

    Each Phi processor is capable of more than teraflop of speed, or one trillion floating point operations per second. A petaflop is 1,000 teraflops, or one quadrillion floating-point operations per second. An exascale system is 1,000 petaflops.

    Dongarra's report suggests that China may have the leading system for some time. "The next large acquisition of a supercomputer for the U.S. Department of Energy will not be until 2015," he wrote.

    China has been developing its own chip technology and has been mixing and matching homegrown tech with imported components. U.S. researchers believe China is heading in the direction of building a supercomputer made entirely of indigenously produced components, including chips.

    The approach of combing China-built technology with American products, is evident in Tiahne-2.

    "There are number of features of the Tianhe-2 that are Chinese in origin, unique and interesting," said Dongarra, in his report. These include a proprietary interconnects, and the Galaxy FT-15, a 16-core processor. He cited the "apparent reliability and scalability" of the system as well.

    The system's power usage, when cooling is considered, is 24 MWs. Power is major issue in achieving exascale. Researchers could assemble, theoretically, an exascale computing system with current technology. But at a billion or so cores, it would need its own power plant to operate.

    To reach exascale, HPC researchers say they need to develop processors, memory and network components that substantially reduce power use. New programming models are also being developed. The problems in achieving exascale are such that Europe, which is investing heavily in its own HPC effort, believes there is a potential to leapfrog the U.S. if breakthrough approaches are discovered to some of these problems.

    U.S. researchers, as recently as last month, warned Congress that the U.S., while the undisputed leader in HPC today, is at risk of falling behind in HPC development unless it commits hundreds of millions of dollars to exascale research. But the ongoing budget dispute and sequestration is leading to a reduction in R&D spending.

    China wants to produce an exascale system before 2020. The U.S., at its present effort, won't produce an exascale system until around 2025, lawmakers were told last month.

    The US supercomputer itself needs as much electricity as a state. How much will this big bad-*** computer need?

    I hope that Chinese electricity stations can take the immense load that is going to be put on them for the sake of national pride :(

    a group of pix about the TH-2 ...souce : ENET china...

    ----------------------------------------
    summary of TH-2 ........ Peak Power (MW) : 17.8
    [​IMG]

    the cooling system 80 KW
    [​IMG]

    the total Power: around 24 MW

    as we know ,power shortage in some country might be common...but not in China nowadays...LOL...
    such comment reminds me some old saying...'Don't measure other people's corn by your own bushel'
    --------------------------------------------
    Chinese made CPU was also used: 4096 chips of FT-1500 VS 32000 Ive Bridge-E Xeon E5 2692+ 48000 Xeon Phi...3,120,000 cores in total

    @shiphone, only 24 MW??

    Thanks for the data.

    So that you know, I heard that first time supercomputer like this was switched on in Japan, power supply of 2 cities went off. :dude:

    What were they thinking?

    24MW( the power of the whole system...usually the whole system would occupy a whole buiding) would be the Peak Power, not very often indeed...

    the TH-1A(the champion of year 2010) in Tianjing, China
    [​IMG]

    I'm afraid the current Champion :TITAN from USA only needs 8.209 MW to achieve the 27.11 petaflop
    Japanese supercomputer --"京“ need 12.66 MW(VS TH-2's 17.6 MW) to achieve the 11.28 petaflop...
    I have never heard of what you claimed. please check your source...

    the latest list: Top500 List - November 2012

    and the early lists : http://www.top500.org/lists/

    -------we would find the development of Supercomputer is so fast and the competition between the countries is stiff..

    Indeed. It has become a matter of national pride in Japan.
