China Builds World's Fastest Supercomputer Without U.S. Chips (computerworld.com)

Reader dcblogs writes: China on Monday revealed its latest supercomputer, a monolithic system with 10.65 million compute cores built entirely with Chinese microprocessors. This follows a U.S. government decision last year to deny China access to Intel's fastest microprocessors. There is no U.S.-made system that comes close to the performance of China's new system, the Sunway TaihuLight. Its theoretical peak performance is 124.5 petaflops (Linpack is 93 petaflops), according to the latest biannual release today of the world's Top500 supercomputers. It has been long known that China was developing a 100-plus petaflop system, and it was believed that China would turn to U.S. chip technology to reach this performance level. But just over a year ago, in a surprising move, the U.S. banned Intel from supplying Xeon chips to four of China's top supercomputing research centers. The U.S. initiated this ban because China, it claimed, was using its Tianhe-2 system for nuclear explosive testing activities. The U.S. stopped live nuclear testing in 1992 and now relies on computer simulations. Critics in China suspected the U.S. was acting to slow that nation's supercomputing development efforts. There has been nothing secretive about China's intentions. Researchers and analysts have been warning all along that U.S. exascale (an exascale is 1,000 petaflops) development, supercomputing's next big milestone, was lagging.

    This happens when you don't allow export of your chips to someone who has the knowledge to design their own chips.
    It gives them the incentive to accelerate development and deployment of their homegrown designs.

    Not only do you lose a business opportunity, you're also in danger of losing your technology leadership.

      It is pretty idiotic that our foreign policy and military establishment seem intent on picking periodic fights with China over stupid little things rather than trying to elevate the relationship to become close allies.

      Have you been living under a rock for the last several years? The Chinese have been using dredgers to build artificial islands atop coral reefs in the South China Sea, and these islands are now equipped with huge runways for operating military craft from fighters to patrol aircraft to medium bombers; all so they can project firepower over the entire South China Sea. To simply claim the entire Sea right up to the coasts of their regional neighbors as their own is one thing, but China has invested in a massive military build-up to back up their claims with raw force. Many of those nations are our regional allies, especially the Philippines. And if that's not enough, the Chinese have long engaged in hostile cybercrimes against the United States, not only hacking critical military defense information (like the information on the F-35 they stole) but also an ongoing government-ran campaign to steal American commercial trade secrets that mirrors their complete and utter disdain for Western Intellectual Property rights.

      And you're going to tell me that America is the one "picking fights" because we dared sail a ship too close to a few of their sand-castles? Freedom of Navigation exercises are run frequently, all over the globe, and are NOT mutually exclusive with traditional diplomacy.

      I understand that some people are deeply suspicious or even disdainful of America's role in world politics; but when you try to make out the 800 pound gorilla of Asia - who's busy mugging everyone it can get its hairy paws on - as the poor victim here, you just come across as a moron.

    The older systems, like Longson, are MIPS using a questionable license with patent problems.

    These systems are directly derived from DEC Alpha.

    So, not homegrown, more like "homecloned" from US chips and then enhanced.

    In other words, the hard work was already done, and they just took it.

    I used to teach a pretty decent load of Chinese students in my classes in Manhattan (I taught at both NYU and on CUNY). By the '00s, they were significantly more creative, sophisticated, well-rounded, and learned (I make no claims about "intelligence") than my American students, who were really sort of "decadent" in the worst, stereotypical ways—knew only a few things about a few things but a lot about consumer goods and fashion, and didn't seem to think they needed to work, just didn't feel the global pressure from competing workers. Very entitled.

    The Chinese students tended to cluster in 'A' territory and always approached me after class to talk about class topics until I had to leave, then followed up with serious questions by email. The American students always had one or two in the 'A' group and the rest clustering around low B and high C, and it was a struggle just to learn their names, as they had nothing at all to say to me unless I called on them in class. Ironically, many of the Chinese students had better formal English as well, though there were always also about half that were clearly 'winging it' and needed ESL—but were killing it in class performance anyway, managing to learn and to get through books by relying on a dictionary, a study group, and sheer determination.

    I found some data on watts. It looks like the chinese computer is 16MW and the Titan is 8MW. So it appears they are using lower power, slower CPUs on the SHenWei. Overall this means they are getting better petaflops per watt than the US computer. Thus I was incorrect in saying it was pointless brute force. They are one the way to lower gigaflops/watt.

    Yeah, the Chinese Supercomputer is using 1.45 GHz 260-core custom-ISA 64-bit RISC chips.

    Yup, 260 cores. Each with a 256-bit FMAC SIMD unit. It's not a traditional CPU architecture, it clearly uses some aspects of Intel's Larrabee/Knights Landing platform, and GPU architectures (in particular the cache arrangement).

    Each chip can process 3 TFLOPS of double precision floating point.

    > was it stolen outright?
    About 20 years ago, our IT manager at DEC noticed an extremely large download being made to the office in Japan over the weekend. He killed the connection and investigated. They were accessing the Alpha design docs and got away with pretty much everything. They were just starting to download the process docs and didn't get very far. So we at the time knew we'd see something Alphaish popping up in China about a decade later. In 2006 the ShenWei appeared on the scene and it bore striking resemblance to the Alpha 21164A, the processor design docs that happened to be downloaded that weekend long ago.
