The latest "TOP500" list of supercomputers ranks first in the United States. Is China behind in supercomputing?

On May 30th, the 59th ISC2022 (International Supercomputing Conference) released the latest TOP500 list. The "Frontier" of Oak Ridge National Laboratory (ORNL) in Tennessee, USA, scored 1.102 exaflops, becoming the first supercomputer to truly break through the Exascale mark.

And in this list,China’s Shenwei Taihu Lake Light ranks sixth, and Tianhe No.2 ranks ninth, which is lower than that of previous years, and its computing power is not as good as one tenth of that of the United States.?

Supercomputing has long been regarded as one of the symbols of comprehensive national strength. Because the computing power far exceeds that of ordinary computers, the application scenarios of supercomputing include nuclear explosion test, weather forecast, astrophysical simulation, cryptanalysis and other fields.

The TOP500 list is compiled by the international organization "TOP500", which ranks the installed supercomputers in the world and is published once every six months. It is worth mentioning that the TOP500 is ranked according to the calculation speed, that is, how many floating-point operations can be performed per second.

So, has China’s supercomputing power fallen behind?

The number of China supercomputers entering the TOP500 ranks first in the world.

To see the strength of a country’s supercomputer, in addition to the calculation speed of a single supercomputer, it also depends on the number of supercomputers that a country can list.

This time, a total of 173 supercomputers in China entered the TOP500 list, accounting for 34.6% of the world, ranking first;The second-ranked United States has 128 supercomputers on the shortlist, accounting for 25.6%; In Japan, which ranked third, 33 entered the list, accounting for 6.6%.?

Actually, fromSince 2016, the number of Chinese super-calculations entering the TOP500 list has basically remained in the first place in the world except for a slight decline in June 2017.

Compared with Europe, America, Japan and other countries, China started late in supercomputing. In June 1995, China’s supercomputer first appeared in the TOP500 list. In the next 17 years, the number of supercomputers entering the TOP500 list in China has been rising, with a maximum of 228, accounting for 45.6% of the list.

?

The number of Americans entering the list has dropped significantly compared with the peak.

But after 2016, China and the United States are catching up with each other, which can be described as "two men competing for hegemony", and almost take turns to be the champion and runner-up in the number of super-calculations.

China has not submitted the test data of the E-class prototype.

From the speed of single supercomputer, China was the first frequent visitor.

2010In 2006, China’s "Tianhe II" was born and won the first place in the list, which is also the first place in China’s supercomputer.

However, in the latest super-calculation ranking, China ranked out of the top five. Among them, Shenwei Taihu Light ranked sixth, and Tianhe No.2 ranked ninth.

Compared with previous years, China’s ranking is indeed much lower, and it is not high compared with other supercomputers in the list, even less than one tenth of the "frontier" of the United States.

What is the reason?

If we study this list carefully, we will find that China’s super-calculated production time is really a little "long" compared with other countries.

This is not only reflected in this year’s list. In the previous eight lists released by TOP500, the production time of Shenwei Taihu Light and Tianhe 2, the top ten in China, was 2016 and 2018 respectively.

Supercomputers from other countries in the top ten on the list were almost all produced in the past two years. For example, the "frontier" where the United States won the title in 2022 was produced and delivered in 2021, while the "Fuyue" where Japan won the title in 2021 and 2020 was produced and delivered in 2020.

In the field of supercomputing, a year and a half can differ by an era. For example, the "frontier" of the US hegemony isThe first supercomputer that really broke through the Exascale mark, its performance reached 1.102exaflops, which also marked a new era of supercomputing.The arrival of e-class supercomputer.

In addition to the "frontier", the United States also has two E-class supercomputers, "Aurora" and "Emirates Rock", which are also under construction.

So, is China lagging behind in the field of E-class supercomputer? This is not the case.

As early as 2016, Zhongke Shuguang officially launched the development project of E-class supercomputer. In 2018, Tianhe No.3 prototype and Shenwei E-class prototype began to enter the host R&D and deployment. In 2018, CCTV also disclosed that the prototype of "Tianhe No.3" passed the acceptance test, and its computing power reached E level. At present, three prototype systems with different technical routes have been delivered in China: Shenwei E-class prototype, Tianhe-3 E-class prototype and Shuguang E-class prototype.

However, China did not submit the test data of the E-class prototype this time. Many foreign media infer that the peak value of Shenwei E-class supercomputer on HPL benchmark is about 1.3 exaflops/1.05 exaflops, while Tianhe No.3 can reach the peak value of 1.7 exaflops /1.3 exaflops, both exceeding Frontier’s 1.102 exaflops.

Looking at the mystery behind the list from the super-calculation suppliers

The question is: why don’t we take the latest supercomputer and American PK?

This is a bit complicated to say.

The above picture is a comparison between China and the United States of the global supercomputer suppliers. It can be found that,The number of over-calculated suppliers in China is getting less and less in TOP500.From 2021, there are only six left, even lower than the seven in 2010. In the TOP500 list released in November 2016, the number of super-calculated suppliers in China has reached 11, which is very small compared with the United States.

On the contrary, American Supercomputer has more and more suppliers.In recent two years, the number of suppliers is even more than twice that of China.

In addition, China suppliers who have appeared in the TOP500 in recent years are still old faces. For example, Lenovo, which has won the first place for many times, has participated in the manufacturing and deployment of 161 supercomputers, accounting for 32.2% in the world; There are 50 finalists in Inspur, accounting for 10%, ranking third; Shuguang ranked fifth with 36 units, accounting for 7.2%; Huawei ranked tenth with 1.4%.

Why are there fewer and fewer super-calculated suppliers in China on the list?

On the one hand, China relies less and less on multinational companies in supercomputing.After 2016, companies such as IBM, Dell, Hewlett-Packard, etc. appear less and less frequently among China’s supercomputing suppliers. Since 2021, only our own companies and institutions remain in the list of supercomputing suppliers in China, including Lenovo, Zhongke Shuguang, Inspur, National University of Defense Technology, National Center for Parallel Computer Engineering and Technology (NRCPC) and Huawei.

On the other hand, the TOP500 on the list is more likely to be included in the entity list by the US.

On April 8, 2021, Tianjin Feiteng Information Technology Company, Shanghai Integrated Circuit Technology and Industry Promotion Center, Sunway Microelectronics, National Supercomputing Jinan Center, National Supercomputing Shenzhen Center, National Supercomputing Wuxi Center and National Supercomputing Zhengzhou Center were blacklisted by the United States; In June 2019, the United States included Zhongke Shuguang, Haiguang, Chengdu Haiguang, Chengdu Haiguang Microelectronics Technology and Jiangnan Computing Technology Research Institute in the entity list; Back in 2015, National University of Defense Technology, Changsha National Supercomputing Center, Guangzhou National Supercomputing Center (NSCC-GZ) and Tianjin National Supercomputing Center were listed by the United States. Being included in the list of entities means that the above-mentioned companies must obtain permission from the US government before doing business with American companies, and the United States intends to fundamentally prohibit these companies from acquiring almost all advanced technologies developed in the United States.

Lin Xinhua, deputy director of the Network Information Center of Shanghai Jiaotong University and an HPC expert, said that TOP500 has become a de facto entity list. "Entering TOP500 is to promote international cooperation, but the result is counterproductive."

This is why China will no longer provide the latest data of supercomputing after 2020.

Looking at the rankings in recent years, the real players in the field of supercomputing are actuallyUnited States, China and Japan.And the ranking will not change much in a short time.

Under the background that the US government has repeatedly generalized the concept of national security, abused state power, abused the list of entities, and suppressed China’s high-tech enterprises maliciously by all means in order to safeguard its own monopoly and hegemonic position in science and technology and curb China’s development,It may be a kind of wisdom to choose the angle of exposure in the list.


The first three "stable" targets in the regulation of the property market do not give force to firm accountability.

  Chinanews. com client Beijing, August 8 th Title: The first three "stable" targets in the regulation of the property market are not firmly accountable.

  Author: Zhang Xu Qiu Yu

  Only seven days before the the Political Bureau of the Communist Party of China (CPC) Central Committee meeting called for "resolutely curbing the rise in housing prices", the Ministry of Housing and Urban-Rural Development held a symposium on real estate work in some cities in Shenyang, Liaoning Province on the 7th, which made it clear that cities with poor property market regulation should be firmly held accountable, and put forward the key points and specific targets of property market regulation.

  Three words of "stability" define the future regulation goal

  The the Political Bureau of the Communist Party of China (CPC) Central Committee meeting held on July 31st demanded that we make up our minds to solve the real estate market problems, adhere to the policy of the city, promote the balance between supply and demand, reasonably guide expectations, rectify the market order, and resolutely curb the rise in housing prices. Accelerate the establishment of a long-term mechanism to promote the stable and healthy development of the real estate market.

  How should all localities do a good job in regulating the real estate market? At the symposium on the 7th, the relevant person in charge of the Ministry of Housing and Urban-Rural Development pointed out that according to local conditions, precise policies and comprehensive policies should be implemented to ensure the market stability.

  According to Zhang Bo, the chief analyst of 58 Anjuke Real Estate Research Institute, the three words "stable" clarify the key points of specific regulation in the future, which means not only to control housing prices, but also to have stable requirements for land prices. In the context of increasing environmental uncertainties at home and abroad, it is particularly important to stabilize expectations.

  How to implement it? Resolutely accountability where regulation is weak!

  How to achieve "stable land price, stable house price and stable expectation"?

  The Ministry of Housing and Urban-Rural Development will establish a real estate market monitoring system and improve the evaluation and assessment mechanism for local real estate regulation and control. Strict supervision, and resolutely accountability for places where work is ineffective, market fluctuations are large, and regulatory targets have not been achieved.

  I love Gong Yucan, a senior analyst of my family group research institute. This symposium is a further promotion of "housing and living without speculation, renting and purchasing at the same time", which means that the regulation of the real estate market will only be tighter, and it will not be relaxed. Linking the regulation of the property market with government performance and resolutely accountability will help promote local governments to implement central policies.

  Earlier, the the State Council executive meeting held on July 23rd proposed that "the proactive fiscal policy should be more active and the prudent monetary policy should be moderate", which made many people worry that funds would flow to the property market.

  Yang Xianling, president of RealData, believes that under this background, the stability of expectations is very important, and the key to stabilizing expectations is to achieve a dynamic balance between supply and demand. In the next stage, the main responsibility of local governments in regulation and control will be further increased, and the assessment mechanism should be more clear and accurate.

  In order to stabilize expectations, the forum also made it clear that we should support reasonable housing consumption, resolutely curb speculative real estate speculation, strengthen public opinion guidance and expected management, and continue to carry out special actions to control chaos in the real estate market.

  In fact, in the second half of the year, the Ministry of Housing and Urban-Rural Development and other ministries and commissions have launched special actions to control the chaos in the real estate market in 30 cities including Beijing and Shanghai, cracking down on speculative real estate speculation, real estate "black intermediaries", illegal real estate development enterprises and false real estate advertisements, and announced the blacklist of 20 institutions on July 31.

  What are the strong measures for local regulation?

  Xie Yifeng, president of China Urban Real Estate Research Institute, believes that after the three "stable" targets are put forward for the first time, under the accountability mechanism, local governments will intensify their regulation and control, and in the future, local governments will increase their policies to limit land prices and introduce more supporting policies to implement them.

  Zhang Bo believes that the Ministry of Housing and Urban-Rural Development once again emphasizes the implementation of local main responsibilities. In order to control housing prices, local governments may adopt three means: First, implement a more stringent price limit policy; Second, the policy upgrade is a "patch", and the upgrade of Shenzhen’s regulatory policy from four limits to eight limits is a typical example; Third, set the "daily limit" of house prices, especially when the control effect is not obvious by patching.

  Xie Yifeng also said that the number of cities with restricted sales is expected to increase, and cities with higher pressure of rising house prices will expand their restricted areas.

  In the opinion of analysts, Shenyang is a case. In June, the price of new houses in Shenyang rose by 1.4% month-on-month and 9.8% year-on-year, while that of second-hand houses rose by 1.4% month-on-month and 5.7% year-on-year. On August 6th, Shenyang introduced a new policy to regulate the property market, expanding the scope of purchase restriction from some areas to the whole city.

  The property market "Golden September and Silver 10" may be difficult to reproduce.

  Xie Yifeng predicted that under the background of continuous overweight regulation, the property market will mainly cool down, and the growth rate of volume and price will fall back, so it may be difficult to reproduce this year’s property market.

  According to the statistics of the Central Plains Real Estate Research Center, in the first seven months of 2018, the regulation of major cities accumulated 260 times. In July alone, the regulation intensity of the national property market set a new record, and more than 60 cities issued more than 70 regulation policies.

  At present, in July, the cooling trend of property market transactions appeared.

  The 40-city residential transaction report released by Yiju Real Estate Research Institute shows that in July, the transaction area of first-tier cities decreased by 7% from the previous month; The transaction area of second-tier cities decreased by 6% from the previous month; The transaction area of 18 third-and fourth-tier cities decreased by 7% from the previous month.

  Yang Xianling said that at present, the property market has entered a spontaneous cooling stage, and the fundamentals of further price increase have weakened. It is expected that the market will enter a "bistable stage" in the future, that is, the market will stabilize and fall back, and the policy will become stable after overweight. (End)

  Anhui:The results of the college entrance examination will be announced in late June.

  These "routines" for candidates should be vigilant.

  During the college entrance examination, various related frauds emerged one after another.

  Candidates and parents should be alert to the following "routines"

  Beware of being cheated

  Someone in the circle of friends "picked up the admission ticket"

  Recently, someone claimed in the WeChat circle of friends.I found the college entrance examination admission ticket and asked for urgent forwarding so that the candidates could find it back.. In fact, this kind of information is a rumor that appears every year.Please stop forwarding such information.. In fact, these people with ulterior motives, with the help of a scam set by the college entrance examination, attracted public attention on the grounds of finding the admission ticket, attracted traffic or waited for opportunities to defraud.

  Check the scam in advance

  After the college entrance examination, criminals will take advantage of the anxiety of some candidates and parents to defraud text messages by mass mailing.Lie that there is a "special channel" to check the college entrance examination results in advance, and attach a link to the website of "query scores". If you enter information such as identity information, bank account information and mobile phone verification code, the money of the bank card may be transferred away by criminals.

  When checking scores in the college entrance examination, we should look for the inquiry method and website designated by the education department.Don’t easily click on the URL link of unknown origin in strange text messages and emails, and you can’t fill in personal information, bank card account information and SMS verification code information on strange websites at will, so beware of being cheated!

  "special channel" admission scam

  The criminals lied to the candidates and their parents that the number of places in a university was not full, and the candidates could get internal places by spending money to "manage"In order to defraud candidates and parents of money.

  The public security organ reminds that formal enrollment will not generate any additional fees.All "special channels" that need to collect deposits, admission fees and index fees are fraud!

  Fake admission notice scam

  Criminals pretend to be college admissions officers,Send a forged admission notice or send a related admission message to the examinee, so that the examinee can pay the tuition fee into the designated bank account., in order to defraud money.

  Fraudulent application for "bursary" scam

  After obtaining the relevant information of candidates through illegal channels, criminals pretend to be college teachers or education department staff.Lie that you can apply for or distribute grants and scholarships in advance to candidates with difficulties or excellent grades.At the same time, in the name of "expired if you don’t get it",Require to pay "handling fee" and "registration fee" in advance.So as to implement fraud.

  If you receive similar information, candidates and parents shouldVerify the authenticity of information to universities, education and other departments through official channels in time, and don’t blindly believe it..

  "Confusing and Faking University Information" Scam

  In recent years, the websites of admissions departments and WeChat WeChat official account in some regions and schools have been registered in advance by some individuals and institutions.Criminals fake universities, official enrollment institutions, school websites or school public accounts to fabricate and spread false information, confuse candidates and parents, and seriously disrupt the order of examination enrollment..

  The public security organ reminds us that the list of national colleges and universities with the qualification to enroll students in this college will be published on the official website of the Ministry of Education every year. Candidates and parents can check and verify by logging in the "List of National Colleges and Universities" under the "Literature" section of the official website of the Ministry of Education.Remind the majority of candidates that when inquiring about college enrollment information online, please look for the "official website" logo and beware of fake accounts or website scams..

  What are the precautions after the exam?

  one

  Protect personal information security

  Candidates should carefully keep important information such as personal admission ticket number and login password, always be vigilant, avoid personal information from being leaked to others, and prevent criminals from illegally using information and infringing on personal rights and interests.

  2

  Relieve anxiety and regulate mood.

  If you feel anxious after the exam, candidates and parents can try the following methods to relieve anxiety and adjust their emotions.

  Relaxation training

  Breathing relaxation and muscle relaxation are commonly used methods to relieve anxiety. When you are anxious, you should pay attention to your breathing. You need to control your breathing and breathe evenly. Don’t let your breathing frequency get faster, and your anxiety will not get worse.

  Moderate exercise

  When you are anxious, if conditions permit, you can do some sports that you usually like to do. Aerobic exercise is the most effective way to relieve generalized anxiety disorder or reduce the tendency of panic, such as running, brisk walking, outdoor cycling or indoor pedaling, swimming and aerobics dancing.

  Learn to eat without anxiety

  Caffeine, nicotine and stimulants can all cause anxiety. Salt, preservatives, hormones in meat, and bad eating habits (eating too fast, eating while walking, eating too much, drinking too much soup/drink in one meal) can lead to increased stress.
