When the cabinet door is opened, four super nodes composed of 32 computing plug-ins are distributed among them. Each plug-in is composed of four operation node boards, and one operation node board contains two "Shenwei 26010" high performance processorsone cabinet has 1024 processors, and the whole Shenwei Taihu Lake light has 40960 processors. Each single processor has 260 cores, the motherboard is designed with two nodes, and the fixed on-board memory of each CPU is 32gbddr3-2133
as for the layout of computer rooms, Taihu light adopts the layout of 20 computer cabinets and storage cabinets on both sides, and single row network system cabinets in the middle
< H2 > important featuresHigh Performance: Shenwei Taihu light double precision floating-point system has a peak value of 125 PFlops and a stable performance of 93 PFlops. Compared with Titan, the double precision floating-point system has a peak value of 27 PFlops and a stable performance of 17.6 PFlops, and Tianhe 2 has a peak value of 54.9 PFlops and a stable performance of 30.65 PFlops
high efficiency: the overall efficiency of Shenwei Taihu Lake light is 74.16%, compared with 65.19% of supercomputing Titan and 55.83% of supercomputing River 2. The stronger the supercomputing performance and the larger the scale are, the more difficult it is to improve the overall efficiency of Shenwei Taihu Lake light, The overall efficiency is still much better than Titan
low power consumption: the power consumption of "Shenwei Taihu Lake light" is 15.3 MW, that of American supercomputer Titan is 9 MW, and that of Tianhe 2 is 17.8 MW. It can be said that the stability performance of "Shenwei Taihu Lake light" is three times that of Tianhe 2, but the power consumption of the whole machine is lower than that of Tianhe 2
high performance / power consumption ratio: the performance / power consumption ratio of "Shenwei Taihu Lake light" is as high as 6G / W, compared with the competitors on the top 500 supercomputing list, the performance / power consumption ratio of Tianhe 2 is 1.95g/w, that of Titan supercomputing is 2.143g/w, and that of Redwood supercomputing is 2.069g/w, The power consumption ratio of Japan's supercomputing "Beijing" is 0.830/w, and that of American supercomputing Mira is 2.069g/w (both Mira and Sequoia use IBM power)
small size: "Sunway Taihu Lake light" cabinet covers an area of 605 square meters, American supercomputer Titan cabinet covers an area of 404 square meters, Tianhe No.2 cabinet covers an area of 720 square meters
< H2 > main performance1, peak performance of 125.436pflops, world's second
2, sustained performance of 93.015pflops, world's first
3, performance power consumption ratio of 6051mflops / W, world's first
According to reports, at 4:00 a.m. Beijing time on the 17th, at the global supercomputing conference held in Denver, the application of "nonlinear large earthquake simulation" based on China's "Shenwei · Taihu Lake light" supercomputing system won the "Gordon bell" award, and the "Shenwei · Taihu Lake light" supercomputing system became the world's fastest supercomputing system for the fourth time in a row
in the future, "Sunway · light of Taihu Lake" will focus on the world's major scientific and technological needs, continue to carry out high-performance computing application services, make contributions to the world's scientific and technological innovation, support the national high-performance computing development strategy and the construction of an innovative country, and play an important role in energy, environment, advanced manufacturing and other fields
The theoretical floating-point performance is 125435.9tflops (floating-point operations per second), while the actual performance in Linpack test is 93014.6tflops (floating-point operations per second)
has 74% efficiency, which is higher than tianhe-2 (62%) and Titan (65.8%). The graphic performance of this unit is also outstanding, ranking second in graph500. However, the bottleneck effect of memory access begins to appear when there are more frequent operations and more integer operations
compared with tianhe-2 system, the power consumption of tianhe-2 system is 17.8 million watts (24 million watts when the cooling system is turned on at full speed), while Shenwei Taihu light only uses 15.3 million watts, and the performance of each watt reaches 6 gflops / W, ranking 20th in the green 500 energy efficiency ratio by November 2017

Application
the earth system science research center of Tsinghua University cooperated with the Department of computer science to realize the numerical simulation of the earth system with the scale of one million nuclei and high resolution for the first time by using "Shenwei Taihu Lake light". Previously, the Chinese mainland's earth simulation system could only achieve the resolution of 200 km grid scale, but now it can carry out the earth system simulation of 25 km grid resolution, and it can reach 10 km resolution on the ocean. p>
at present, more than 30 user units have carried out cooperation with National Supercomputing Wuxi center in weather and climate, aerospace, marine science, new drug creation, advanced manufacturing, new materials and other fields
in 2016, the application software of "global atmospheric non static cloud resolution simulation" on Shenwei Taihu Lake light supercomputer won the Gordon Bell Award, which was awarded to the application software design award on supercomputer, because the effective performance of hardware ultimately depends on software design. In the previous 30 years, the award was won by the United States and Japan, and a third country broke this rule for the first time
No. Shenwei Taihu light supercomputer is a supercomputer developed by the national parallel computer engineering technology research center, known as the "national key", Taihu light is a starting combination. One of the most critical is the call and configuration between all chips. It's like a road network in a city. Internet cafes can't be used (similar to the difference between central air conditioning and household single air conditioning). You can't play games
According to the report, at the global supercomputing conference held in Denver at 4:00 a.m. Beijing time on the 17th, the application of "nonlinear large earthquake simulation" based on China's "Shenwei · Taihu Lake light" supercomputing system won the "Gordon bell" award, realizing China's high-performance computing application in this award
in the future, China's aviation and aerospace research institutions are cooperating with Wuxi supercomputer to simulate various flight states of C919 large aircraft and Tiangong series spacecraft, which can not only proce more realistic animation rendering effect, but also greatly shorten the proction cycle
I hope the utilization rate of Shenwei Taihu Lake light can be continuously improved
