Microsoft computing resources
there is also a model called cloud computing power, which is derived from the traditional use of mining machine to mine. It is in Sichuan, Xinjiang, Tibet and other places with abundant and cheap power resources, such as wind power generation and water conservancy power generation, that large-scale mines are built and maintained by professional personnel. If ordinary people participate in mining, they don't need to buy mining machines in person. They just need to buy the corresponding computing power to get bitcoin and Ethereum! This model is called cloud computing power!
for example, if an enterprise has its own computing software resources, but does not have computing hardware devices such as servers, then it can consider renting servers and other hardware cooperation methods on the tenth power computing platform, so as to avoid investing a lot of money at one time
furthermore, if an enterprise does not have both hardware and software resources, it can directly output the calculation results through the existing calculation projects of the tenth power, or output the customized calculation scheme according to the specific application of the enterprise.
which is the best choice for computing power service
are you asking about the Bank of computing power
since the tenth power bank was proposed, it has attracted the attention of many people in the instry, and there are more and more related topics. So what do we think of the bank
to sum up, computing power bank is a sharing platform of hardware platform leasing + professional software application, which is based on P2P network. Through this platform, we can carry out in-depth cooperation in instry applications, customize professional computing power solutions, and create a new computing power output mode
Supercomputing Center's computing services are generally charged. You can go to the 10th power to learn about it. At present, the 10th power has launched free computing services
the tenth power cooperates with computing earth to launch the world's largest distributed computing resource computing power supply platform, providing free computing power support for projects requiring a large amount of computing power output. The computing power bank can provide idle computing power of personal devices worldwide, providing computing power support for world-class scientific research projects, involving mathematics, physics, chemistry, life sciences, astronomy and other fields
so far, the peak computing power is as high as 100p, which is equivalent to the computing power of tianhe-2, the world's fourth largest supercomputer, and can meet the needs of all computing power projects on the market
the birth and development of modern computer before the advent of modern computer, the development of computer has gone through three stages: mechanical computer, electromechanical computer and electronic computer
as early as the 17th century, a group of European mathematicians began to design and manufacture digital computers that perform basic operations in digital form. In 1642, Pascal, a French mathematician, made the earliest decimal adder by using a gear transmission similar to clocks and watches. In 1678, Leibniz, a German mathematician, developed a computer to further solve the multiplication and division of decimal numbers
British mathematician Babbage put forward an idea when he made the model of difference machine in 1822. One arithmetic operation at a time will develop into a certain complete operation process automatically. In 1884, Babbage designed a program-controlled universal analyzer. Although this analyzer has described the rudiment of the program control computer, it can not be realized e to the technical conditions at that time< During the more than 100 years since Babbage's idea was put forward, great progress has been made in electromagnetics, electrotechnics and electronics, and vacuum diodes and vacuum triodes have been successively invented in components and devices; In terms of system technology, wireless telegraph, television and radar were invented one after another. All these achievements have prepared technical and material conditions for the development of modern computer< At the same time, mathematics and physics are developing rapidly. In the 1930s, all fields of physics experienced the stage of quantification. The mathematical equations describing various physical processes, some of which were difficult to solve by classical analysis methods. As a result, numerical analysis has been paid attention to, and various numerical integration, numerical differentiation, and numerical solutions of differential equations have been developed. The calculation process has been reced to a huge amount of basic operations, thus laying the foundation of modern computer numerical algorithm
the urgent need for advanced computing tools in society is the fundamental driving force for the birth of modern computers. Since the 20th century, there have been a lot of computational difficulties in various fields of science and technology, which has hindered the further development of the discipline. Especially before and after the outbreak of the Second World War, the need for high-speed computing tools in military science and technology is particularly urgent. During this period, Germany, the United States and the United Kingdom started the research of electromechanical computer and electronic computer almost at the same time<
Giuseppe in Germany was the first to use electrical components to make computers. The fully automatic relay computer Z-3, which he made in 1941, has the characteristics of modern computer, such as floating-point counting, binary operation, instruction form of digital storage address and so on. In the United States, the relay computers mark-1, mark-2, model-1, model-5 and so on were made successively from 1940 to 1947. However, the switching speed of the relay is about one hundredth of a second, which greatly limits the computing speed of the computer
the development process of electronic computer has experienced the evolution from making components to whole machine, from special machine to general machine, from "external program" to "stored program". In 1938, the Bulgarian American scholar atanasov first made the computing unit of the electronic computer. In 1943, the communications office of the British Foreign Office made the "giant" computer. This is a special cryptanalysis machine, which was used in the Second World War< In February 1946, ENIAC, a large-scale electronic digital integrator computer, was developed by Moore College of the University of Pennsylvania in the United States. At first, ENIAC was also specially used for artillery trajectory calculation. Later, it was improved many times and became a general-purpose computer capable of various scientific calculations. This computer, which uses electronic circuit to perform arithmetic operation, logic operation and information storage, is 1000 times faster than relay computer. This is the first electronic computer in the world. However, the program of this kind of computer is still external, the storage capacity is too small, and it has not fully possessed the main characteristics of modern computer
the new breakthrough was completed by a design team led by mathematician von Neumann. In March 1945, they published a new general electronic computer scheme of stored program - electronic discrete variable automatic computer (EDVAC). Then in June 1946, von Neumann and others put forward a more perfect design report "preliminary study on the logical structure of electronic computer devices". From July to August of the same year, they taught a special course "theory and technology of electronic computer design" for experts from more than 20 institutions in the United States and Britain at Moore college, which promoted the design and manufacture of stored program computers< In 1949, the Mathematics Laboratory of Cambridge University in England took the lead in making EDSAC; The United States made the eastern standard automatic computer (SFAC) in 1950. At this point, the embryonic period of the development of electronic computer came to an end, and the development period of modern computer began
at the same time of creating digital computer, we also developed another kind of important computing tool analog computer. When physicists summarize the laws of nature, they often use mathematical equations to describe a process; On the contrary, the process of solving mathematical equations may also adopt the physical process simulation method. After the invention of logarithm, the slide rule made in 1620 has changed multiplication and division into addition and subtraction for calculation. Maxwell skillfully transformed the calculation of integral (area) into the measurement of length, and made the integrator in 1855< Fourier analysis, another great achievement of mathematical physics in the 19th century, played a direct role in promoting the development of simulators. In the late 19th century and the early 20th century, a variety of analytical machines for calculating Fourier coefficients and differential equations were developed. However, when trying to popularize the differential analysis machine to solve partial differential equations and use the simulator to solve general scientific calculation problems, people graally realize the limitations of the simulator in the aspects of universality and accuracy, and turn their main energy to the digital computer
after the advent of electronic digital computer, analog computer still continues to develop, and hybrid computer is proced by combining with digital computer. Simulators and mixers have become special varieties of modern computers, that is, efficient information processing tools or simulation tools used in specific fields
since the middle of the 20th century, the computer has been in a period of high-speed development. The computer has developed from a hardware only system to a computer system which includes three subsystems: hardware, software and firmware. The performance price ratio of computer system is increased by two orders of magnitude every 10 years. The types of computers have been divided into microcomputers, minicomputers, general-purpose computers (including giant, large and medium-sized computers), and various special computers (such as various control computers and analog-to-digital hybrid computers)
computer devices, from electron tubes to transistors, from discrete components to integrated circuits to microprocessors, have made three leaps in the development of computers< In the period of electron tube computer (1946-1959), computers were mainly used for scientific calculation. Main memory is the main factor that determines the appearance of computer technology. At that time, the main memory included mercury delay line memory, cathode ray oscilloscope electrostatic memory, magnetic drum and magnetic core memory, which were usually used to classify computers.
in November, the market value of iota soared more than 8 times, leaping to the top four in the digital currency list, successfully beating the old digital currency reborn. Iota mainly serves the Internet of things, and the point of speculation is also the Internet of things, and the Internet of things is also a popular concept in the past two years, so it is reasonable for the price of iota to soar. However, as an old digital currency, etc has begun to test the Internet of things as a breakthrough. So, as the two giants in the field of Internet of things, who can stand out in the future competition? Let's make a simple comparison
etc is the built-in encrypted digital currency of the original Ethereum chain, and the system has been running stably for a long time. Its core development team is composed of technical experts with rich experience in blockchain development. The decision-making and implementation of its technical scheme are democratic and scientific. The technology used by iota is similar to lightning network and lightning network. Lightning network technology itself is a more avant-garde technology. Bitcoin core development group first proposed to use lightning network technology to solve the problem of bitcoin expansion, but it has only stayed in the theoretical stage and has not been put into practice. The community generally believes that this technology is lack of practical test and its stability needs to be tested
The cryptography theory and principle used byetc has been widely used in other IT fields and has been verified and optimized for a long time. It is a mature, safe, reliable and efficient information technology. Iota uses balanced ternary (numerical system represented by three digits) on binary hardware devices, which leads to the design of the system is too complex and the computational efficiency is reced. Another serious problem of this design is that the cryptographic hash algorithm must be redesigned, which brings serious security risks. In short, this technology is still in the theoretical stage, too avant-garde, does not have the value of practical application
the issuance of etc is completely decentralized, the currency price is not easy to be manipulated, and the new monetary policy will be implemented soon, which will guarantee the upper limit of the issuance of etc from the system and make it a compact digital currency, so as to ensure its value storage attribute. Iota is an ICO project in 2014, which has always been neither hot nor hot. A large number of iota tokens are in the hands of a few people, and the price is easy to be manipulated, which is one of the reasons why the price has increased eight times in less than a month. This trend of centralization is very disadvantageous to the long-term development of the community. Iota does not need to mine, there is no transaction fee, each participant provides computing power for the network, and there is no corresponding incentive measures, which is extremely unfavorable to the stability of iota network
iota uses tangle technology, which is not a real blockchain, but just to solve the problem of blockchain expansion. Blockchain is just a cover for iota. Therefore, iota as a technology can be used in the Internet of things, but it can not be used as a digital currency
compared with iota's blind pursuit of new technology, new concept and new theory, etc is more keen on mature and stable technology and continuous innovation under the premise of safety and stability. The Internet of things is also one of the biggest application scenarios of etc. The etc development team has started to develop the Internet of things friendly virtual machine, making it universal, independent and efficient
in addition, in order to make better use of IOT applications, etc community has reached a consensus and made a development plan of cross chain operation function. In view of the increasing transaction data in the field of Internet of things, the fragmentation technology and side chain technology are designed to ensure the security and improve the efficiency. The goal of etcdev team is to make etc blockchain a stable and easy-to-use technology. It's better to slow down the development progress than to do some rash experiments to prevent irretrievable errors from causing users' losses in the future
In a word, etc is more like a stable and easy-to-use technology, while iota is more like a rash experiment. The most important thing for large-scale application of technology is to be stable and easy to use, rather than blindly pursuing new concepts and technologies. Therefore, etc has the incomparable universality of iota, and has stronger application support ability in the field of Internet of thingsFrom the perspective of data analysis, data center is undoubtedly a "big energy consumer". The annual power consumption of a super large data center is nearly 100 million kwh. The total electricity consumption of national data centers in 2018 is 160.889 billion kwh, which is more than the total social electricity consumption of Shanghai in 2018 (156.7 billion KWH), equivalent to the annual power generation of the Three Gorges dam
Internet giants such as Microsoft, Google, Alibaba and Tencent build green and efficient data centers. As instry promoters and practitioners of green energy-saving technology, enterprises are not only based on their own business needs, but also the major social responsibilities of enterprises and the whole instry.
