    More raw power to design advanced weapons and weapons of mass destruction, among other things. :rolleyes:

    "In Surprise, China Unveils Supercomputer Based on Its Own Chips

    China has made its first supercomputer based on Chinese microprocessor chips, an advance that surprised high-performance computing specialists in the United States.

    The announcement was made this week at a technical meeting held in Jinan, China, organized by industry and government organizations. The new machine, the Sunway BlueLight MPP, was installed in September at the National Supercomputer Center in Jinan, the capital of Shandong Province in eastern China.

    The Sunway system, which can perform about 1,000 trillion calculations per second — a petaflop — will probably rank among the 20 fastest computers in the world. More significantly, it is composed of 8,700 ShenWei SW1600 microprocessors, designed at a Chinese computer institute and manufactured in Shanghai.

    Currently, the Chinese are about three generations behind the state-of-art chip making technologies used by world leaders such as the United States, South Korea, Japan and Taiwan.

    “This is a bit of a surprise,” said Jack Dongarra, a computer scientist at the University of Tennessee and a leader of the Top500 project, a list of the world’s fastest computers.

    Last fall, another Chinese based supercomputer, the Tianhe-1A, created an international sensation when it was briefly ranked as the world’s fastest, before it was displaced in the spring by a rival Japanese machine, the K Computer, designed by Fujitsu.

    But the Tianhe was built from processor chips made by American companies, Intel and Nvidia, though its internal switching system was designed by Chinese computer engineers. Similarly, the K computer was based on Sparc chips, designed at Sun Microsystems in Silicon Valley.

    Dr. Dongarra said the Sunway’s theoretical peak performance was about 74 percent as fast as the fastest United States computer — the Jaguar supercomputer at the Department of Energy facility at Oak Ridge National Laboratory, made by Cray Inc. That machine is currently the third fastest on the list.

    The Energy Department is planning three supercomputers that would run at 10 to 20 petaflops. And the United States is embarking on an effort to reach an exaflop, or one million trillion mathematical operations in a second, sometime before the end of the decade, though most computer scientists say the necessary technologies do not yet exist.

    To build such a computer from existing components would require immense amounts of electricity — roughly the amount produced by a medium-sized nuclear power plant.

    In contrast, Dr. Dongarra said it was intriguing that the power requirements of the new Chinese supercomputer were relatively modest — about one megawatt, according to reports from the technical conference. The Tianhe supercomputer consumes about four megawatts and the Jaguar about seven.

    The ShenWei microprocessor appears to be based on some of the same design principles that are favored by Intel’s most advanced microprocessors, according to several supercomputer experts in the United States.

    But there is disagreement over whether the machine’s cooling technology is appropriate for designs that will be required by the exaflop-class supercomputers of the future.

    Photos of the new Sunway supercomputer reveal an elaborate water-cooling system that may be a significant advance in the design of the very fastest machines.

    “Getting this cooling technology correct is very, very difficult,” said Steven Wallach, chief scientist at Convey Computer, a supercomputer firm based in Richardson, Tex. 'This tells me that this is a serious design. This cooling technology could scale to exaflop. They are in the hunt to win.'”

    Homegrown China Supercomputer Hits One Petaflop with Lower Power

    Surprise! China has built a supercomputer using homegrown chips, an unexpected announcement this past week that showcases the country's determination toward lessening its dependence on foreign-grown CPUs.

    According to an article in the New York Times this Friday, the Sunway BlueLight MPP supercomputer resides in the National Supercomputer Center in eastern China. Installed this past September, the system houses a total of 8,700 ShenWei SW1600 processors that feature 16 cores apiece. Combined with an advanced water-cooling system – the specific details of which are currently unknown – the supercomputer is expected to reach a total processing power of around one petaflop. But more importantly, it can allegedly do so using only a megawatt of power.

    While the system's specs are likely enough to place it in the top-20 ranking of the world's fastest supercomputers, the Sunway BlueLight MPP's power draw is raising a few more eyebrows. For starters, it's all of one-fourth that of China's previous chart-topping supercomputer, the Tianhe-1A.

    Debuted last year, the 2.5-petaflop Tianhe-1A – the world's fastest supercomputer at the time of its unveiling – ate up 4.04 megawatts of power. And the system itself was built on chips from both Intel and Nvidia, a far contrast from China's current CPU load-out in the Sunway BlueLight MPP.

    The fastest U.S. supercomputer at the moment – Jaguar – eats up about seven megawatts to output roughly 1.7 petaflops of processing performance.

    China's new system is but one more volley in the ongoing international race to hit an exaflop, or one thousand petaflops, at some point within the next decade. To do so, however, will likely require a massive energy output – right now, approximately the same amount of power as that which is generated by a medium-sized nuclear power plant, said the New York Times' John Markoff.

    That's what makes the combination of power-savings, cooling, and petaflop performance so intriguing at the moment, as it's the key formula that the world's various supercomputer manufacturers will need to master in order to reach their exaflop targets – representing a thousand trillion calculations per second, we note.

    China's goal is to be able to deploy an exaflop-class system, using China-built chips, by 2020. The U.S. is hoping to reach an exaflop by 2019 through upgrades to its Jaguar – soon-to-be "Titan" – supercomputer, and Europe expects to reach its exaflop goal within a similar timeframe.

    Wow. Petaflop!! I've heard of flops and super-flops, but a peta-flop must be a massive flop indeed!! :D

    So when is ShenWei going to outshine Intel in the micro-processing market?
