    HANGZHOU — A Chinese Academy of Sciences (CAS) research institute and Aliyun, Alibaba's cloud computing subsidiary, have released a cloud platform for quantum computing.

    The platform was announced online by Aliyun and the CAS innovative center for quantum information and quantum physics (Shanghai) at a cloud computing conference Wednesday in Hangzhou, East China's Zhejiang province, where Alibaba is based.

    The platform will offer users a development and testing environment for cloud-based quantum algorithms.

    Pan Jianwei, lead scientist of China's quantum experiments at space scale and a member of the academy, said the platform would help industrialize quantum computing.

    "If a classic computer is compared to a bicycle in computation speed, a quantum computer is like a jet," said Pan.

    Cooperation between CAS and Aliyun dates back to July 2015, when a quantum computing laboratory was launched. In May 2017, the world's first prototype quantum computer was developed by the laboratory and two Chinese universities.

    Tianhe-3: China says its world-first exascale supercomputer will be ready by 2020
    China already holds the two fastest supercomputers. Now it hopes to knock the USA off the third spot with the first ever exascale machine. Tianhe-3 will handle one quintillion calculations per second.

    Fast isn't the word. If China's Tianhe-3 supercomputer manages to hit the exascale mark, it will handle one quintillion calculations per second.

    NB: 1 quintillion = 1,000 000 000 000 000 000 (yep, that's 18 zeros)

    Meng Xiangfei, a director at the National Supercomputer Center at Tianjin, told the China Daily newspaper that his institute aims to have a prototype of its Tianhe-3 ready by 2018. For that they will need breakthroughs in high-performance processors. But Meng is confident.

    If they succeed, Tianhe-3 will be 10 times faster than the current fastest supercomputer in the world, the Sunway TaihuLight.

    The Sunway runs at 93 petaFLOPS, with a reported peak speed of 125 quadrillion calculations per second.

    1 quadrillion = 1,000 000 000 000 000 (15 zeros)

    "Its computing power is on the next level," Meng told the newspaper. "It will help us tackle some of the world's toughest scientific challenges with greater speed, precision and scope."

    The Tianhe-3 will be measured in exaFLOPS.

    Its sibling, the Tianhe-2 runs at 34 petaFLOPS, while the USA's next best, Titan, creaks in at 18 peteFLOPS.

    If the Tianhe-3 breaks the peta-barrier, its processing speed will leave the rest for dead - which is probably a good thing as supercomputers don't have the longest life-expectancy.

    Super, but compared to what?

    How can we even begin to image the Tianhe-3's processing speeds?

    Well, one of the world's first computers (as we know them) was the Zuse Z3. It was a programmable, digital computer. Based on the same Boolean theory that gave us the zeros and ones of modern computing, the Z3 was the first solid implementation of so-called "flip-flops" and what became "floating point" arithmetic.

    A computer's processing speed is measured (in part) by the number of floating points it can handle per second - and that's why we refer to a FLOP or FLOPS.

    In 1941, the Z3's average single calculation speeds were 0.8 seconds for addition and 3 seconds for multiplication.

    Fast-forward 70 years or so and the average smartphone will perform addition and multiplication almost before we've finished entering the numbers…Imagine that, predictive math!

    Smartphones speeds tend to be measured in gigaflops (1 GFLOP = 1,000 000 000), but it's hard to get a good read on the latest models as the manufacturers are so competitive and as a result secretive. It is said, however, that Apple's A-series chips, which are made by Imagination Technologies, are years ahead of Qualcomm's Snapdragon chips, which Samsung and Google use in their phones.

    Gaming consoles are a lot faster than smartphones, but then again nothing compared to a supercomputer. It would take more than 18,000 Playstation 4s to match the Tianhe-2 - which, to remind us, is half as fast as China's Sunway supercomputer, and that is 10 times slower than the Tianhe-3 will be.

    Like I said, fast just isn't the word. But, then, the Tianhe-3 won't be a toy. Chinese scientists hope to use it to analyze smog distribution, gene sequence and protein structures to help develop new medicines. They also say it will simulate earthquakes and epidemic outbreaks in greater detail, "allowing swifter and more effective government responses."

    The fiftieth TOP500 list of the fastest supercomputers in the world has China overtaking the US in the total number of ranked systems by a margin of 202 to 143. It is the largest number of supercomputers China has ever claimed on the TOP500 ranking, with the US presence shrinking to its lowest level since the list’s inception 25 years ago.

    Just six months ago, the US led with 169 systems, with China coming in at 160. Despite the reversal of fortunes, the 143 systems claimed by the US gives them a solid second place finish, with Japan in third place with 35, followed by Germany with 20, France with 18, and the UK with 15.

    China has also overtaken the US in aggregate performance as well. The Asian superpower now claims 35.4 percent of the TOP500 flops, with the US in second place with 29.6 percent.

    The top 10 systems remain largely unchanged since the June 2017 list, with a couple of notable exceptions.

    ----------------------------------------------------------

    China already becomes the leader in supercomputer manufacturing in the world.

    Functionless builds. The US supercomputers are based on function.

    Nope, I say it because the US supercomputers are built to fulfil a function, whereas China are just experimenting to see what they can build.

    Look at the number of nodes the Chinese designs need.
    https://www.top500.org/lists/2016/11/

    Unless you can split a problem into that many paths, the extra compute power isn't even useful.

    The building blocks just aren't there. Sure, they can put lots and lots of crappy CPUs together to get something with more FLOPS, but the base level technology isn't there.

    The fiftieth TOP500 list of the fastest supercomputers in the world has China overtaking the US in the total number of ranked systems by a margin of 202 to 143. It is the largest number of supercomputers China has ever claimed on the TOP500 ranking, with the US presence shrinking to its lowest level since the list’s inception 25 years ago.

    Just six months ago, the US led with 169 systems, with China coming in at 160. Despite the reversal of fortunes, the 143 systems claimed by the US gives them a solid second place finish, with Japan in third place with 35, followed by Germany with 20, France with 18, and the UK with 15.

    China has also overtaken the US in aggregate performance as well. The Asian superpower now claims 35.4 percent of the TOP500 flops, with the US in second place with 29.6 percent.

    The top 10 systems remain largely unchanged since the June 2017 list, with a couple of notable exceptions.

    Sunway TaihuLight, a system developed by China’s National Research Center of Parallel Computer Engineering & Technology (NRCPC), and installed at the National Supercomputing Center in Wuxi, maintains its number one ranking for the fourth time, with a High Performance Linpack (HPL) mark of 93.01 petaflops.

    Tianhe-2 (Milky Way-2), a system developed by China’s National University of Defense Technology (NUDT) and deployed at the National Supercomputer Center in Guangzho, China, is still the number two system at 33.86 petaflops.

    Piz Daint, a Cray XC50 system installed at the Swiss National Supercomputing Centre (CSCS) in Lugano, Switzerland, maintains its number three position with 19.59 petaflops, reaffirming its status as the most powerful supercomputer in Europe. Piz Daint was upgraded last year with NVIDIA Tesla P100 GPUs, which more than doubled its HPL performance of 9.77 petaflops.

    The new number four system is the upgraded Gyoukou supercomputer, a ZettaScaler-2.2 system deployed at Japan’s Agency for Marine-Earth Science and Technology, which was the home of the Earth Simulator. Gyoukou was able to achieve an HPL result of 19.14 petaflops. using PEZY-SC2 accelerators, along with conventional Intel Xeon processors. The system’s 19,860,000 cores represent the highest level of concurrency ever recorded on the TOP500 rankings of supercomputers.

    Titan, a five-year-old Cray XK7 system installed at the Department of Energy’s (DOE) Oak Ridge National Laboratory, and still the largest system in the US, slips down to number five. Its 17.59 petaflops are mainly the result of its NVIDIA K20x GPU accelerators.

    Sequoia, an IBM BlueGene/Q system installed at DOE’s Lawrence Livermore National Laboratory, is the number six system on the list with a mark of 17.17 petaflops. It was deployed in 2011.

    The new number seven system is Trinity, a Cray XC40 supercomputer operated by Los Alamos National Laboratory and Sandia National Laboratories. It was recently upgraded with Intel “Knights Landing” Xeon Phi processors, which propelled it from 8.10 petaflops six months ago to its current high-water mark of 14.14 petaflops.

    Cori, a Cray XC40 supercomputer, installed at the National Energy Research Scientific Computing Center (NERSC), is now the eighth fastest supercomputer in the world. Its 1,630 Intel Xeon "Haswell" processor nodes and 9,300 Intel Xeon Phi 7250 nodes yielded an HPL result of 14.01 petaflops.

    At 13.55 petaflops, Oakforest-PACS, a Fujitsu PRIMERGY CX1640 M1 installed at Joint Center for Advanced High Performance Computing in Japan, is the number nine system. It too is powered by Intel “Knights Landing” Xeon Phi processors.

    Fujitsu’s K computer installed at the RIKEN Advanced Institute for Computational Science (AICS) in Kobe, Japan, is now the number 10 system at 10.51 petaflops. Its performance is derived from its 88 thousand SPARC64 processor cores linked by Fujitsu’s Tofu interconnect. Despite its tenth-place showing on HPL, the K Computer is the top-ranked system on the High-Performance Conjugate Gradients (HPCG) benchmark.

    For the first time, each of the top 10 supercomputers delivered more than 10 petaflops on HPL. There are also 181 systems with performance greater than a petaflop – up from 138 on the June 2017 list. Taking a broader look, the combined performance of all 500 systems has grown to 845 petaflops, compared to 749 petaflops six months ago and 672 petaflops one year ago. Even though aggregate performance grew by nearly 100 petaflops, the relative increase is well below the list’s long-term historical trend.

    A further reflection of this slowdown is the list turnover. The entry point in the latest rankings moved up to 548 teraflops, compared to 432 teraflops in June. The 548-teraflop system was in position 370 in the previous TOP500 list. The turnover is in line with what has been observed over the last four years, but is much lower than previous levels.

    A total of 102 systems employ accelerator/coprocessor technology, compared to 91 six months ago. 86 of these use NVIDIA GPUs, 12 systems make use Intel Xeon Phi coprocessor technology, and 5 are using PEZY Computing accelerators. Two systems use a combination of NVIDIA GPU and Intel Xeon Phi coprocessors. An additional 14 systems now use Xeon Phi chips as the main processing unit.

    Green500 Highlights

    Turning to the new Green500 rankings, the top three positions are taken by newly installed systems in Japan, all of which are based on the ZettaScaler-2.2 architecture and the PEZY-SC2 accelerator. The SC2 is a second-generation 2048-core chip that provides a peak performance of 8.192 teraflops in single-precision.

    The most efficient of these ZettaScaler supercomputers is the Shoubu system B installed at RIKEN’s Advanced Center for Computing and Communication. It achieved a power efficiency of 17.0 gigaflops/watt.

    The number two Green500 system is the Suiren2 cluster at the High Energy Accelerator Research Organization/KEK, which managed to reach 16.8 gigaflops/watt.

    The number three Green500 slot was captured by the PEZY Computing’s own Sakura system. It achieved 14.2 gigaflops/watt. All of these top three systems are positioned in the bottom half of the TOP500 rankings: Shoubu system B at position 258, Suiren2 at 306, and Sakura at 275.

    The fourth greenest supercomputer is a DGX SaturnV Volta system, which is installed at NVIDIA headquarters in San Jose, California. It achieved 15.1 gigaflops/watt, and comes in at number 149 on the TOP500 list. The number five system is Gyoukou, yet another ZettaScaler-2.2 machine. It achieved an efficiency of 14.2 gigaflops/watt and it currently ranks as the fourth most powerful supercomputer in the world.

    Vendor trends

    A total of 471 systems, representing 94.2 percent of the total, are now using Intel processors, which is slightly up from 92.8 percent six months ago. The share of IBM Power processors is at 14 systems, down from 21 systems in June.

    The number of systems using Gigabit Ethernet is unchanged at 228 systems, in large part thanks to 204 systems now using 10G Ethernet. InfiniBand technology is found in 163 systems, down from 178 systems in the previous list, and remains the second most-used system interconnect technology in the list. Intel Omni-Path technology is now in 35 systems, down from 38 six month ago.

    HPE has the lead in the number of installed supercomputers at 122, which represents nearly a quarter of all TOP500 systems. This includes several systems originally installed by SGI, which is now owned by HPE. HPE accounted for 144 systems six months ago.

    Lenovo follows HPE with 81 systems down from 88 systems on the June list. Inspur rose further in the ranks and has now 56 systems, up from only 20 six month ago. Cray now has 53 systems, down from 57 systems six month ago. Sugon features 51 systems in the list, up from 44 in June. IBM follows with only 19 systems remaining under their label. These are mostly BlueGene/Q supercomputers, reflecting an aging install base. The average age of IBM systems on the list is now five years.

    Cray continues to be the clear performance leader, claiming 19.5 percent of the list’s aggregate performance. HPE is second with 15.2 percent of the TOP500 flops. Thanks to the number one Sunway TaihuLight system, NRCPC retains the third spot with 11.1 percent of the total performance. Lenovo is fourth with 9.1 percent of performance, followed by Inspur at 6.3 percent, IBM at 6.1 percent and Sugon at 5.2 percent. All top vendors, with the exception of Inspur and Sugon, lost performance share compared to six months ago.

    HPCG Results

    The TOP500 list is now incorporating the High-Performance Conjugate Gradient (HPCG) benchmark results into the list to provide a more balanced look at system performance. The benchmark incorporates calculations in sparse matrix multiplication, global collectives, and vector updates, which more closely represents the mix of computational and data access patterns used in many supercomputing codes.

    As previously mentioned, the fastest system using the HPCG benchmark remains Fujitsu’s K computer, which is ranked number 10 in the overall TOP500 rankings. It achieved 602.7 teraflops on HPCG, followed closely by Tianhe-2 with a score of 580.0 teraflops. The upgraded Trinity supercomputer comes in at number three at 546.1 teraflops, followed by Piz Daint at number four with 486.4 teraflops, and Sunway TaihuLight at number five at 480.8 teraflops.

    The International Space Station computer, built by HPE, is now listed in the HPCG results, making it the “highest” computer on the list.

    Look at the top 5 supercomputer, in power efficiency, Chinese Sunway TaihuLight(rank No.1) is much better than the American Titan(rank No.5)
    From power consuming point of view, the running cost will be higher, but it does not mean it is not useful.

    The Earth System Science Research Center of Tsinghua University cooperated with the Department of Computer Science to realize the numerical simulation of Earth system with millions of nuclear scale and high resolution for the first time by using the "Shenwei · TaihuLight". Earlier, the earth simulation system model in mainland China only reached a resolution of 200 km on a grid scale. However, it is now possible to carry out a simulation of the Earth system with a grid resolution of 25 km at a resolution of 10 km at sea.

    At present, more than 30 user units have cooperated with the State Supercenter Wuxi Center in the fields of weather, aerospace, marine science, new drug creation, advanced manufacturing and new materials . The 2016 Gordon Bell Award for "Global Atmosphere Non-Static Cloud Resolution Simulation" application on the Superconductor of Sunway Taihu Light Supercomputer was awarded to the Design Award for Application Software on Supercomputer because of the effective performance of hardware Ultimately depends on the software design, the previous 30 years the prize was obtained by the United States and Japan, for the first time a third country to break this rule.
