In our daily life, in the morning and evening rush hours, tens of thousands, hundreds of thousands and millions of people across the country may use taxi software at the same time. Some people call taxis, and some drivers are waiting for the call. So much data and information should be processed in a short time, and no mistakes can be made. How is this done?
In the information society, data can be symbols, characters, numbers, sounds, images, videos and so on. Every day when we turn on our mobile phone, we will generate data. Whether it is public service, economic operation, scientific research and other social fields, data are generated all the time, and massive data must be supported by computing power.
Academician Wu Shuo of China Academy of Engineering? The so-called computing power refers to the amount of information and data that can be processed every second. There was a published data. To do vocal recognition, it is necessary to establish a mathematical model and optimize the artificial intelligence algorithm for recognition. The parameter 175 1 needs to be transferred, consuming 45TB data. One behind this is the supply of big data, and the other is to have corresponding computing power to support it. ?
China produces more data than the United States, but in terms of computing power. In 2020, the United States will account for 36% of the global computing power, and China will account for 3 1% of the global computing power, which means that China's computing power cannot meet the large-scale data generated by China. The processing of massive data is completed in the data center.
Bao Jian, assistant general manager of China Mobile Hohhot Data Center, said? The overall computing capacity of the data center can support all users in the country to concurrently execute a taxi travel application. Customers are distributed all over the country, and their needs will be transmitted to the data center for calculation through the Internet within 10 milliseconds. After calculating his needs, the optimal route, the most reasonable driver and the travel plan will be fed back to his mobile phone to complete the process of a taxi software and inform the nearest driver where to pick up the car. ?
In addition to daily services such as taking a taxi by mobile phone, a large amount of data will be generated at all times and in all walks of life, flooding into the data center like seawater, and one of the functions of the data center is to calculate data information through powerful computing power on the basis of network facilities. Not long ago, the National Development and Reform Commission and other four ministries and commissions jointly issued a notice to start the construction of national computing hub nodes in Beijing-Tianjin-Hebei, Yangtze River Delta, Guangdong-Hong Kong-Macao Greater Bay Area, Chengdu-Chongqing, Inner Mongolia, Guizhou, Gansu and Ningxia, and to plan 10 national data center clusters. This national strategic project is also called? East is west? . The transformation of data and computing capacity to a new generation of production factors and the comprehensive promotion of computing capacity infrastructure have been promoted to the level of national strategic resource planning.
? Oriental number? Why? Western computing? ?
He Hezhen said:? The regional development of China is unbalanced. The eastern economy is stronger than the west, and so is the digital economy. In the east, like Shenzhen, its information industry accounts for one tenth of the world's output value; In Shanghai and Beijing, with the development of economy, the demand for data computing power is naturally higher. However, the energy distribution is also unbalanced. On the contrary, China is richer than the West. ?
The higher the computing power, the greater the demand for energy. Walking into a data center, the most intuitive impression is rows of cabinets with rows of servers inside. These servers operate around the clock, performing data exchange, calculation and storage tasks. A large data center cluster, such servers may reach millions or tens of millions, which consumes a lot of electricity, and electricity alone accounts for 70% of the operation and maintenance cost of the data center.
He Hezhen said:? In this case, we can put the power-consuming data center in the west, make better use of energy in the west, and even directly use renewable energy, thus reducing carbon emissions. ?
Many major projects in China are aimed at more rational allocation of resources, such as the South-to-North Water Diversion Project, the West-to-East Power Transmission Project, the West-to-East Gas Transmission Project, and the Dongdian West Computing Project. According to the statistics of relevant departments, in 2020, the electricity consumption of data centers in China has exceeded 200 billion kWh, accounting for about 2% of the total electricity consumption. Huge power demand brings computing power? Move west? Main driving force.
Guizhou, Inner Mongolia and other western regions are rich in electric energy. Building a data center cluster here does not require long-distance power transmission, so the electricity price is low and the operating cost of the data center is low. Inner Mongolia and Guizhou are both good places for summer, and the temperature is not high in summer. This unique climatic condition is more suitable for energy saving and emission reduction in data centers.
? Oriental number? How to get there? Western computing? ?
How to transfer a large amount of data from the east to the data center cluster in the west across thousands of kilometers? By the first half of this year, China's national Internet backbone direct connection points had reached 19. The direct connection point of national Internet backbone is mainly used to gather and dredge the communication traffic between regions and even the whole country, reduce the data transmission delay and greatly improve the speed and quality of inter-network communication. This is the industrial Internet, Oriental Digital and Western Computing. New infrastructure? Develop and lay a solid network foundation.
Zhang Xuerong, director of Guiyang Big Data Development Administration, said: At that time, there were few backbone direct connection points. Unicom users in Guiyang needed to connect to the interconnection point of Guangzhou Unicom, then to the telecom interconnection point in Shanghai and then to Chengdu. Now direct connection can be realized, and the delay can be reduced to less than 20 milliseconds, which is equivalent to the feeling that you play games in Shenzhen and I play games in Guiyang. ?
Shortening network delay is of great significance for promoting the high-quality innovation and development of digital economy. One second is equal to 1000 millisecond. Usually we blink, about 120? 200 milliseconds. After the national Internet backbone direct connection point is completed, the delay from Guizhou to Shanghai can be reduced to 25ms, and that from Guangzhou can be reduced to 12ms. The time delay of mutual visits between Hohhot and Beijing in Inner Mongolia is only about 10 millisecond. Mirror image, that is, in the blink of an eye, data transmission can run 10 back and forth between two places. Powerful computing power and high-speed data transmission make the application of digital technology more extensive, and the development prospect of digital economy is broader.
? East is west? Why is it included in the new infrastructure?
Coordinating the infrastructure construction of China data center will inevitably drive the development and layout of digital industry. ? East is west? It is not only to balance the resources between the east and the west, but also to accelerate the orderly transfer of related industries to the west in the context of the layout of computing infrastructure from east to west. ? Fourteen or five? During the period, it is estimated that the investment in big data centers will increase by more than 20% every year, and the accumulated investment in all aspects will exceed 3 trillion yuan. New infrastructure is the propeller to achieve high-quality economic development. East is west? Building a digital economy? New base? , form a high-quality development? New support? Will also form a high degree of independence in China? New advantages? .
? East is west? How will it affect our social life?
Different from the supercomputing center, supercomputing focuses more on computing and serves the scientific research field, while the big data center undertakes many functions such as data storage, calculation and transmission. 10 national data center cluster layout, to create a cloud ecosystem for our future economic life and serve the whole society. Inner Mongolia uses data center clusters to build a high-performance computing service platform? Light of Qingcheng Mountain? Serve the construction of smart cities.
Accelerate push? East is west? Construction directly benefits all kinds of market players. Data centers provide computing power for all walks of life and enterprises in need, and promote the development of digital economy. The construction of data center not only promotes the rapid development of social economy, but also serves all aspects of people's livelihood. The layout of the national data center cluster will also promote the internationalization of China. When the data center China Bank is completed, it will handle hundreds of millions of transactions around the world every day.
With the continuous improvement of new infrastructure in the digital economy era, various new technologies, new industries, new formats and new models will emerge, which will also promote the regional development of the western region.
He Hezhen said:? The data center in the west can help the west to use computing resources faster, and bring the upstream and downstream industries together through the data center, which is conducive to promoting the economic development of the west, so this is also an important measure to give consideration to regional development. ?
Digital economy is becoming a key force to reorganize the global factor resources, reshape the global economic structure and change the global competition pattern. Computing power has become an indispensable resource such as water, electricity and gas. ? East is west? Right here? New infrastructure? Under the background of China, a vital national project initiated by China; It can not only give full play to the advantages of climate, energy and environment in the western region, but also help China's data centers to achieve low-carbon, green and sustainable development, and inject new kinetic energy into building a digital China and promoting high-quality economic development.
