Lin Yifu said that China hopes that each country can give full play to its comparative advantages. China will continue to open wider to the outside world, allowing more foreign products and capital to enter China. Of course, we also hope that China's products, capital and technology will enter the international market. For a few products that are stuck in the neck, China will also make preparations and use its own advantages to tackle key problems. According to past experience, after a thing can be manufactured and produced in China, the international price will come down, so once China overcomes the key problems and can produce it, it will produce products with lower cost and higher quality, not only for itself, but also for the whole world. Therefore, any attempt to stifle China will only accelerate China's progress and make it lose its competitive advantage.

On April 8th, the website of the US Department of Commerce announced that seven China supercomputing entities were included in the "Entity List". From these seven entities, Tengfei and Shenwei are representative enterprises of domestic CPU chips, and the four national supercomputing centers are quite strong in algorithm and model training. The United States spared no effort to attack China's supercomputer.

Key core technologies can't be bought, come or not, and can't be obtained! Great changes in the past century have put forward more urgent requirements for China's scientific and technological innovation. To firmly grasp the initiative of national development and security in our own hands, we must rely on independent innovation and take scientific and technological self-reliance as the strategic support of national development.

On August 29, 2020, the staff of Wuxi National Supercomputing Center worked next to the supercomputer "Taihu Shenwei Light".

In order to curb the development of China, the United States maliciously suppressed high-tech enterprises in China.

On April 8, local time, the US Department of Commerce announced that seven China supercomputing entities were included in the so-called "entity list", claiming that they were suspected of "undermining the stability of military modernization" and "engaging in activities contrary to US national security or foreign policy interests".

According to the announcement of the US Department of Commerce, the entities involved include Tianjin Tengfei Information Technology Co., Ltd., Shanghai High Performance Integrated Circuit Design Center and Chengdu Shenwei Technology Co., Ltd., as well as the National Supercomputing Jinan Center, Shenzhen Center, Wuxi Center and Zhengzhou Center.

Why target these seven entities? U.S. Department of Commerce officials said that all seven institutions participated in the research and development project of the world's first E-class supercomputer (one billion floating-point operations per second) that China hoped to build. At present, "Shenwei Taihu Light" running in Wuxi Center is the world's first supercomputer with peak computing performance exceeding one billion floating-point operations per second.

Among the seven entities, Shenwei is backed by Wuxi Jiangnan Computing Center and mainly develops CPU chips. In 20 10, Shenwei CPU was adopted by the national supercomputer Jinan center. In 20 16, Shenwei's CPU was used in Wuxi "Shenwei Taihu Light" supercomputer, helping it climb to the top of the world supercomputer TOP500 for three consecutive times, and the CPU and operating system were all localized.

In May 2009, the Ministry of Science and Technology approved the establishment of the National Supercomputing Tianjin Center, and then approved the establishment of five national supercomputing centers in Shenzhen, Jinan, Changsha, Guangzhou and Wuxi. Zhengzhou National Supercomputing Center, which was listed in the "Entity List", just passed the expert acceptance organized by the Ministry of Science and Technology in June 5438+ 10. It is the seventh national supercomputer center approved by the Ministry of Science and Technology, and the first national supercomputer center approved by the Ministry of Science and Technology after the promulgation of the Certification Management Measures.

On April 9th, Zhao, a spokesman for the Ministry of Foreign Affairs, said that in order to maintain its monopoly and hegemonic position in the field of science and technology and curb China's development, the US government has repeatedly generalized the concept of national security, abused state power and abused the "entity list" and suppressed China's high-tech enterprises by any means. China firmly opposes this. In response to the relevant measures taken by the US, China will take necessary measures to resolutely safeguard the legitimate rights and interests of China enterprises.

The rapid progress of Chinese supercomputers has aroused the vigilance and suppression of the United States.

Supercomputers, why are they attracting attention?

As the name implies, a supercomputer is a computer with strong ability to calculate and process data. Generally speaking, the average operation speed of supercomputers is more than 6.5438+million times per second, and the storage capacity is more than 6.5438+million bits.

For a long time, the United States has been leading in the field of supercomputers.

Although it started late, China's series of supercomputers from "Yinhe" to "Tianhe" and "Shenwei" are world-famous brands. China Supercomputer not only achieved many firsts in independent innovation, but also reached the "peak of speed" in the world for generations.

In 2009, China released the "Tianhe-1" supercomputer with peak performance of 1.206 petaflops per second, becoming the second country to independently develop petaflops after the United States.

In 20 16, the international supercomputing conference announced the new ranking of the top 500 supercomputers in the world. China's first "Shenwei Taihu Light" built entirely with domestic processors has become the fastest supercomputer in the world, and its system's three key indicators, such as peak performance, continuous performance and performance-to-power ratio, rank first in the world. Among the top 500 supercomputers in the world, China accounts for 167, surpassing the United States for the first time.

The seven entities listed in the "blacklist" this time are all related to the E-level supercomputer project built by the Chinese side. E-class supercomputer refers to a supercomputer that can perform one billion mathematical operations per second, and is recognized as "the next crown of supercomputer world" by the whole world.

The reason why the United States attaches so much importance to E-class supercomputing is mainly because supercomputing is of great value to national economic development and national defense construction, and has important applications in many fields.

Zhang Yunquan, a researcher at Institute of Computing, Chinese Academy of Sciences and secretary-general of High Performance Computing Committee of China Computer Federation, pointed out that E-class supercomputer can play a great role in solving major problems such as health crisis, energy crisis, environmental pollution and climate change. "From the current point of view, E-class supercomputing mainly faces some major computing needs, such as global climate change simulation, astrophysical big data processing, universe evolution simulation, new material verification and non-inventory nuclear weapons simulation."

According to public reports, the United States announced the construction of three E-class supercomputers last year, namely Aurora, Frontier and Cedeyan. The estimated delivery time is 202 1 2023. China has also carried out "three consecutive deployments" in the field of E-class supercomputer. The self-developed E-class supercomputer "Tianhe No.3" prototype, Shenwei E-class prototype and Shuguang E-class prototype system were delivered on 20 18.

In April of 20 15, the United States began to ban the sale of supercomputing chips in China, and contained them from the industrial chain and technical level. Taking innovation as a breakthrough, China has completed the initial construction of a supercomputer autonomous controllable ecosystem. 2065438+June 2006, the supercomputer "Shenwei Taihu Light" with a processor independently developed by China successfully took over the "Tianhe II" based on Intel chips and won the first place. "Tianhe No.1" and "Tianhe No.2" have tried out the self-developed Fit CPU in a small scale.

In addition, China's supercomputers have developed well in applications, and high-end applications have won the Gordon Bell Award, the highest international high-performance computer award, twice in a row.

The rapid development of China's supercomputing has aroused the vigilance and suppression of the United States. "Supercomputing power is crucial to the development of many (perhaps all) modern weapons and national security systems." US Commerce Secretary Raymond said in a statement.

American "list strike" frequently points to China's science and technology field.

In recent years, the United States has suppressed China's technology, which has long been traceable.

The National Defense Authorization Act of fiscal year 20 19, signed by the President of the United States on August 3, 201018, explicitly prohibits US government departments from purchasing China's services and technical equipment in the field of communication and video surveillance, including but not limited to Huawei, Hikvision, Dahua Technology and ZTE. On May 5, 20 19, 18 issued an administrative order to ensure the security of information and communication technology services and supply chain, and Huawei was officially included in the "entity list" by the Bureau of Industry and Security (BIS) of the US Department of Commerce.

On 202 1, 1 and 65438+5, nine companies including Xiaomi, Comac of China and Zhongwei Semiconductor were included in the so-called "list", and American investors were restricted from trading the securities of these companies. On the morning of 65438+ 10 14, BIS announced that it would add CNOOC to the "entity list" and control its export; On October 5th, 65438/kloc-0, Trump issued an executive order again15th day before leaving the presidency of the United States to remove and restrict eight China applications, such as Alipay, Tencent QQ and WPS Office.

The US government's "list attacks" frequently point to China's scientific and technological fields. The US government mainly uses three lists and presidential executive orders as sanctions against China enterprises, namely, the entity list, the military end-user list (MEU) and the so-called "* * * manufacturer's list of military enterprises in China". These three lists mainly restrict the supply chain and financing of China enterprises, while the presidential executive order restricts China enterprises from doing business in the United States. The above sanctions can be combined.

Among the three lists, the most familiar one is the "entity list" involving Huawei, which is also the most severe and longest-lasting one among various economic and supply sanctions in the United States. Since May 20 19, the US government has launched several rounds of supply sanctions against Huawei. Simply put, entering the "entity list" means that American suppliers need to obtain permission from the US government before exporting to them, and such permission will be strictly examined and restricted.

The other two lists are new sanctions vigorously promoted by the U.S. government in 2020 on the pretext that enterprises are involved in the military industry or related to the military. The difference between the two is that both MEU and the entity list are supply restrictions, which are under the charge of the US Department of Commerce, while the so-called "list of manufacturers of China's military enterprises" is aimed at restricting Americans from trading securities and derivatives of companies, which is formulated by the US Department of Defense. In June 5438+February last year, 58 China enterprises were included in the first MEU list, including many aircraft manufacturers, such as Comac and Xifei. At present, dozens of China enterprises and entities including Huawei, DJI and CNOOC have entered the "entity list"; Included in the so-called "list of China military enterprises producing * * *" are 44 China enterprises including SMIC, Huawei, Inspur, China Telecom, China Mobile, Aerospace Science and Technology and China Railway Construction.
