China Dominates the World TOP500 Supercomputers

[S10]

Now the real question is what kind of frame rate am I gonna get on 4k Ultra HD playing Star Wars: Battlefront on maximum setting.

 

[C130]

But you guys have sacrificed so much to Trump's white guys!
Mother lands deserve some supa computa.

we love China

Pinoy and Viet don't need supa computa, but if they want one they can contact IBM or Cray

White people like Trump may like China, but I don't think non-white like those boat refugees do the same.

40,960 nodes @ 180W= 7.37MW so that means everything else consumes 8MW

if China wanted to build a 300Pflop using SW26010 it would need 3x the nodes

122,880 nodes (31,800,000 cores) @180W=22.11MW+24MW for everything else= 46.11MW supercomputer

so I don't believe China claim it will upgrade Tianhe-2 to 300 petaflop any time soon not using SW26010 for that matter


6 giglaflops per watt isn't enough.

P100 at 4.7 Tflop @250 watts is 18.5Gflops/watt 3x the efficency of SW26010

China still has a long way to go

For the world's fastest computer that could bring enormous benefits on economic and national security, who cares to pay some additional money for the electricity??

we don't know what it will be used for.

I wouldn't be suprised if China has a secret supercomputers deep under a mountain that is 5 times faster.

the money adds up if it's for non-military users, $100,000 a day electric bill isn't cheap.

 

[TaiShang]

After more rounds of defeat by Chinese. American will accept the reality of superior Chinese

Time heals all wounds. Even those to the pride. LOL.

$100k/day isn't cheap, but still bearable. Right? Especially when considering the huge benefits could be brought by this giant: a significant cut on R&D time, more R&D projects could be proceeded in parallel, a much faster response to new market trends, blabla

Power Mac G4 banned from China
Winnie Lai (Computerworld) 03 November, 1999 12:01


Apple's Power Mac G4, touted as the first personal computer to deliver supercomputer-level performance, arrived in Hong Kong last week.

But it won't be allowed to cross the border to China without a licence, due to US government national security restrictions on the export of high-speed machines.

Under US regulations, the Mainland, together with Israel, Russia, Pakistan and 45 other countries, belongs to the so-called Tier III category, meaning that computers performing at over 2,000 MTOPS (millions of theoretical operations per second) are prohibited from being exported to those countries without a license from the US government.

The newly-introduced 450MHz Power Mac G4 has a processing power of 2,775 MTOPS and therefore will not be sold on the Mainland, confirmed Tony Li, Apple's Hong Kong-based marketing director.

As a means of preventing customers from shipping the machine to the Mainland by mistake, the G4 carton is being labeled with the following warning: "The G4 computer in this box is for use in Special Administrative Region of Hong Kong only. Export to the People's Republic of China is prohibited by law."

Li noted, however, that it is legal for subsidiaries or branch offices of Mainland companies located in Hong Kong to purchase the G4 for use in the SAR. And he indicated that whether the machine is ultimately shipped to the Mainland is not Apple's problem. "This depends on the watchful eyes of the Customs and Excise Department," he said.

Li maintains that it is unlikely that the G4 will make it into the Mainland via gray market channels. "Since the PRC government's large-scale crackdown on smuggling at the end of last year, a great majority, if not all, machines enter the Mainland market through legal channels," he said. "If that were not the case, we'd see unstable pricing since those smuggled in don't need to pay duties and therefore can be sold at a much cheaper price. So far, we haven't noticed any such situation," he said, referring to other Apple machines.

If a G4 does make its way to the Mainland, Apple will be able to refer to the serial number of the machine to trace the reseller, and will take appropriate action as necessary, Li said.

Li declined to quantify the revenue hit Apple will be taking by not being able to sell the G4 on the Mainland. He stressed that Mainland customers will continue to have access to Apple products since the G3 line will continue to be available.

Tianhe-2 notorious hard to code for, and SW26010 has gimped memeory.

Chinese researchers would be better off using Stampede II or Mira than TaihuLight

Cost is a relative concept. Is the US military spending too much? Considering the overall benefits, it is not. So, China spending on advanced technology is never too much because of countless direct and indirect positive impact.

Asking China to stop supercomputer investment is more ridiculous than asking the US to scarp eight of some 11 AC battle groups.

Trump will ensure non-white to pay white to use supa computa.

Trump will build a supercomputer and the Mexicans will pay for it.

 

[ChineseTiger1986]

Both Sunway and Tianhe are not the frontrunner of the China's supercomputing technology, and those supercomputers using the microchips are obsolete and to be soon reached its bottleneck.

China's true supercomputing goal for this century is the quantum supercomputer. The quantum satellite in the coming July will be even a more exciting news than the Taihulight-1.

He will!
Non-white boat refugees and Hispanic will pay white companies to use supa computa!

GS Zhou, Taihulight is the seocnd most efficient suprecoputer ever built, reached to 6G/W..if compared with GREEN500 LIST, November 2015, can be the 2nd.

高性能——神威太湖之光双精浮点峰值高达125PFlops，稳定性能为93PFlops，相比较之下，美国超算泰坦的双精浮点峰值高达27 Pflops，稳定性能为17.6 PFlops，天河2号的双精浮点峰值高达54.9Pflops，稳定性能为30.65PFlops，由此可见，“神威太湖之光”在稳定性能是美国超算泰坦的5.2倍（泰坦很可能是美国现在顶尖的超算之一，完成升级的Stampede 2性能为18PFlops）。

高效率——“神威太湖之光”整机效率高达74.16%，相比较之下，美国超算泰坦的整机效率为65.19% ，而河2号的整机效率为55.83%，由于超算性能越强，规模越大，整机效率提升就越困难，“神威太湖之光”在稳定性能是美国超算泰坦5.2倍的情况下，整机效率依然大幅优于泰坦，整机效率之高简直令人惊骇！

低功耗——“神威太湖之光”的功耗为15.3 MW，美国超算泰坦功耗为9MW，天河2号为17.8 MW，可以说，“神威太湖之光”的稳定性能达到天河2号3倍的水平，但整机功耗却低于天河2号。

性能功耗比高——“神威太湖之光”的性能功耗比高达6G/W，相比之下，TOP500超算榜单上的竞争对手都相形见绌——天河2号的整机性能功耗比为1.95G/W，美国泰坦超算的性能功耗比为2.143G/W，美国超算红杉整机性能功耗比为2.069G/W，日本超算“京”整机性能功耗比为0.830/W，美国超算Mira 整机性能功耗比为2.069G/W（Mira和红杉用的都是IBM的Power）……即便是全球Green500排行榜，“神威太湖之光”也能排至第三位。由于Green500排行榜第一和第二的超算只采用了低功耗版的Intel E5，性能非常弱，而即便是采用英伟达K80加速卡的超算，其整机性能功耗比也只有4.7G/W。因此，“神威太湖之光”在性能功耗比上显得格外耀眼。

小体积——“神威太湖之光”机柜占地605平方米，美国超算泰坦机柜占地面积404平方米，天河2号机柜占地面积720平方米。

News Analysis: Great leap for Chinese-made supercomputers, but challenges remain

Source: Xinhua | 2016-06-21 07:02:36 | Editor: huaxia

WUXI, June 20, 2016 (Xinhua) -- Photo taken on June 20, 2016 shows Sunway TaihuLight, a new Chinese supercomputer, in Wuxi, east China's Jiangsu Province. Performing 93 quadrillion calculations per second, Sunway TaihuLight dethroned China's Tianhe-2 from the top in a list of the 500 most powerful supercomputers in the world. Sunway TaihuLight, with 10,649,600 computing cores comprising 40,960 nodes, is twice as fast and three times as efficient as Tianhe-2, which has a performance of 33.86 quadrillion calculations per second, or petaflop/s. The new system was developed by the Chinese National Research Center of Parallel Computer Engineering & Technology and installed at the National Supercomputing Center in Wuxi. (Xinhua/Li Xiang)

WASHINGTON, June 20 (Xinhua) -- It's no longer big news that a Chinese supercomputer dominates a list of the world's fastest machines these days, but a No. 1 system built using entirely made-in-China chips instead of U.S. technology is no doubt a milestone.

China's Sunway TaihuLight, which is capable of performing 93 quadrillion calculations per second (petaflop/s), was on Monday declared having replaced Tianhe-2 as the world's most powerful supercomputer on the so-called Top500 list.

Tianhe-2, also a Chinese system, had previously topped the list for the past three years with a performance of 33.86 petaflop/s, but it's built with U.S.-made Intel chips.

Monday's announcement marked a great leap forward in China's ambitions to develop its homegrown computing and chipmaking industry. It's no secret China has a deep worry over foreign reliance, especially after the U.S. government announced an export ban on all high-performance computing chips to China last year.

Now, China's persistent supercomputing investment seems to be paying off.

"The Sunway TaihuLight system, based on a homegrown processor, demonstrates the significant progress that China has made in the domain of designing and manufacturing large-scale computation systems," said Jack Dongarra, professor of the University of Tennessee and editor of the list, in a report about the new supercomputer.

He said Sunway TaihuLight is running "sizeable applications," a fact that caused him to believe the system "is capable of running real applications and not just a stunt machine."

Depei Qian, a professor at Beihang University and the chief scientist of China's 863 project on high productivity computer and grid service environment, called the new system a "landmark event."

"This is the first time we use domestic processors to take the top spot on the Top500 list, marking a big step in China's development of self-controllable supercomputers," Qian told Xinhua. "This system is not only leading in computing performance, but also has technological breakthroughs in areas including energy efficiency and size. It's very impressive."

Zizhong Chen, a supercomputer expert at the University of California, Riverside (UCR), said Chinese should be proud of the Sunway TaihuLight system.

"It shows that with long-term efforts of Chinese computer experts, China's IT technology is developing rapidly," said Chen. "It also means that China has mastered the main core technologies for building supercomputers and therefore China's ability to compete in the supercomputing domain is getting stronger and stronger."

What is equally surprising for the latest list is that China also has more supercomputers than the United States, with 167 compared to 165. This is the first time the United States has lost the lead.

"It's a trend with China," Dongarra told Xinhua. "They had zero systems in 2001 and today they surpass the United States. No other nation has seen such rapid growth."

Dongarra noted that supercomputers are "more important than ever" as they provide capability benefiting a broad range of industries, including energy, pharmaceutics, aircraft, automobile and entertainment.

Experts, however, were quick to point out that China is still far from being a real challenger or threat to U.S. supercomputing dominance.

"Overall, the United States is still in the lead, and Japan is also a strong contender," Qian said. "The U.S., Japan and Europe have an advantage over us in supercomputing applications, so China cannot be blindly optimistic."

Qian also said some Chinese systems on the latest list are not strictly supercomputers, but only systems such as data centers, which usually are not accounted for in the U.S. and Japan.

"So, the numbers aren't everything," he said.

The United States is now ready to regain lost ground. Last July, U.S. President Barack Obama signed an executive order to announce the National Strategic Computing Initiative, which aims to build supercomputer about 10 times faster than the Sunway TaihuLight system.

The U.S. Department of Energy has already allocated 525 million dollars to build three supercomputers with performances greater than 100 petaflop/s, which are expected to come into service around 2018.

Japan also is trying to stage a comeback with a new supercomputer project called Flagship 2020.

"We could see lead changes on the Top500's top position in the next few years, so we should treat that calmly," Qian said.

In order to enhance China's competitiveness in high performance computing, Chen of the UCR advised China to further strengthen development of supercomputer software and applications and training of computing talents, which he said still lagged behind when compared with the U.S., Japan and Europe.

Qian echoed similar problems, including lack of some kernel technologies, relying on imported commercial software and shortage of talents. "China has made some progress," he said, "but the weakness is also obvious."

Also, please keep in mind that while Taihu Light is an extraordinary supercomputer, it has its own limitations, largely because it is extremely customized to run the LinPack Benchmark.

It does significantly poorlyin HPCG benchmark, and surprisingly has a lower memory than even Tianhe 2.
