Today's TOP500 computer, including graphics card computing core. In scientific computing, graphics card is called display accelerator

2. From cheap electricity to centralized mining, China's resources and environment provide bitcoin miners with many advantages. In recent years, bitcoin miners have used cheap electricity to expand their business in coal rich regions such as Xinjiang and Inner Mongolia, which are home to the founders of some of the world's leading mining companies

with the rising price of bitcoin, more and more people join the bitcoin mining business. Accordingly, mining consumes more and more energy. Obviously, our government is also aware of this

according to the requirements of the document, regulators require local governments to take measures related to electricity price, land use, tax and environmental protection to guide bitcoin miners to withdraw from the business. According to foreign media reports, regulatory authorities are mainly concerned about the money laundering and financial risks involved in the shutdown policy, but excessive power consumption is also a factor that can not be ignored. In principle, bitcoin mining consumes a lot of power because every time a new bitcoin is proced, it needs to solve the complex mathematical problems through the encryption process performed by a high-performance computer. Mining calculation process is used to verify bitcoin transactions in the blockchain to ensure security, but the disadvantage is that it consumes a lot of energy.

3. According to IDC's "2018-2019 evaluation report on the development of China's artificial intelligence computing power", by 2022, the investment in computing power in the global artificial intelligence market will exceed 17.6 billion US dollars, and the compound growth rate of the market will exceed 30% in the next five years (2018-2022). And computing power will become an important infrastructure in modern society and an important part of China's new infrastructure strategy. Xnmatrix is a new generation of global and decentralized cloud computing platform, and a new infrastructure in the field of digital economy in the Web3.0 intelligent era.

Computing power is a measure of bitcoin network processing power. That is, the speed at which the computer calculates the output of the hash function. Bitcoin networks must perform intensive mathematical and encryption related operations for security purposes. For example, when the network reaches a hash rate of 10th / s, it can perform 10 trillion calculations per second

in the process of getting bitcoin through "mining", we need to find its corresponding solution M. for any 64 bit hash value, there is no fixed algorithm to find its solution M. we can only rely on computer random hash collisions. How many hash collisions can a mining machine do per second is the representative of its "computing power", and the unit is written as hash / s, This is called workload proof mechanism pow

< H2 > extended data

computing power provides a solid foundation for the development of big data, and the explosive growth of big data poses a huge challenge to the existing computing power. With the rapid accumulation of big data in the Internet era and the geometric growth of global data, the existing computing power can no longer meet the demand. According to IDC, 90% of the global information data is generated in recent years. And by 2020, about 40% of the information will be stored by cloud computing service providers, of which 1 / 3 of the data has value

therefore, the development of computing power is imminent, otherwise it will greatly restrict the development and application of artificial intelligence. There is a big gap between China and the advanced level of the world in terms of computing power and algorithm. The core of computing power is the chip. Therefore, it is necessary to increase R & D investment in the field of computing power to narrow or even catch up with the gap with the developed countries in the world

5. In the process of getting bitcoin through "mining", we need to find its corresponding solution M. for any 64 bit hash value, there is no fixed algorithm to find its solution M. we can only rely on computer random hash collisions. How many hash collisions a mining machine can do per second is the representative of its "computing power", and the unit is written as hash / s, This is the so-called proof of work mechanism (POW)
recently, bitcoin's network computing power has entered the era of P computing power (1P = 1024t, 1t = 1024g, 1g = 1024m, 1m = 1024k). In the soaring computing power environment, the arrival of P era means that bitcoin has entered a new stage of arms race. This is the meaning of computing power. I would like to know more about it Please accept)

6. The tenth power computing bank can help edge computing realize the following functions: different instries have different proction systems, and each enterprise needs its own specific application scenarios

POC particle oxidation catalyst (POC) = particle oxidation catalyst

different from gasoline vehicles, only a few new diesel vehicles adopt exhaust after treatment technology. Automobile diesel engine manufacturers have been improving the engine and its control system to meet the emission standards

The most difficult part is to rece the emission of particulates and nitrogen oxides at the same time in the low temperature lean burn environment

the best effect can be achieved by using diesel lean burn NOx removal catalyst and diesel particulate filter

although this technology already exists, it is very expensive. In most cases, advanced particulate oxidation catalyst POC is used, which is characterized by particulate combustion

The catalyst consists of a new low temperature coating and a metal carrier called Ecocat. At the same time, the conversion of HC and CO can reach 80% - 90%

has been tested on several light and heavy engines and vehicles driven by this type of engine (engines up to Euro 0 to Euro 4 standards). The biggest advantage of this scheme is that the price is relatively cheap and maintenance is not necessary. But the sulfur content in diesel oil should be low

POC is a catalytic oxidizer for particulate matter. The working principle is to catch up the particulate matter, and then burn it through the high temperature of exhaust gas (250 ℃ - 500 ℃), so as to achieve the purpose of recing the particulate matter. POC is widely used in light truck. In addition, POC can regenerate actively and DPF needs human intervention

< H2 > extended data

particulate oxidation catalytic converter (POC) can be used to rece particulate matter in diesel exhaust, which belongs to the category of oxidation catalytic converter. The conversion efficiency of particulate matter is higher than doc, but lower than DPF system. The principle is to make the exhaust gas pass through a multi fold channel without blocking, and the particles are adsorbed in the POC, and the accumulated particles are removed by oxidation combustion

because POC requires a higher working temperature, it needs to be used in combination with DOC, which is called PM Kat system by European heavy truck enterprise man, that is, DOC and POC are integrated. Under the oxidation of DOC catalyst, no in the exhaust gas combines with oxygen to form nitrogen dioxide, and the original NO2 in the exhaust gas enters the POC together. Under the action of the catalyst, the molecular bond of N O2 breaks at a lower temperature, and the generated o burns with the captured C particles to form C O2, thus effectively removing the captured particles

POC can only filter the larger carbon particles, but the ability to capture the carbon particles below PM2.5 is low, and the efficiency of recing PM is 30% - 80%, which is better than doc and lower than DPF. The price of POC is lower than that of DPF and higher than that of doc
