GPU server for mining machinery
Specific steps:
< UL >first of all, we need to find a mine pool which is easy to operate and proces stable output. The role of the mine pool is to subdivide the data packets for each terminal. We can pay the corresponding amount of bitcoin according to the proportion of the data packets calculated by the terminal through the precise algorithm
At present, the mining machines in the market are mainly divided into two categories, one is PC based mining machine, the other is professional mining machine based on ASIC chip
the general PC mining machine can be used as a home computer, but the CPU performance is weak and the power consumption is high. Professional mining machine based on ASIC chip can not be used as ordinary computer because it has no graphics card and does not support mainstream desktop operating system
extended data:
mining machine is one of the ways to obtain Bitcoin is a kind of network virtual currency proced by open source P2P software. It doesn't rely on a specific currency institution to issue, but is generated by a large number of calculations of a specific algorithm. It uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions economically. The decentralized nature of P2P and the algorithm itself can ensure that the currency value cannot be manipulated by mass proction
any computer can become a mining machine, but the profit will be relatively low, and there may not be one in ten years. Many companies have developed professional mining machines, which are equipped with special mining crystal. They are tens or hundreds of times higher than ordinary computers
mining is actually a competition of performance and equipment. The mining machine composed of many graphics cards, even if it is just a garbage card like hd6770, can surpass the single graphics card of most users in terms of computing power
and this is not the most terrible. Some mining machines are made up of more such graphics card arrays. When dozens or even hundreds of graphics cards come together, the graphics card itself costs money. Considering the hardware price and other costs, there are considerable expenses in mining
in addition to the display card burning machine, some ASIC (application specific integrated circuit) professional mining machines are also put into the battlefield. ASIC is specially designed for hash operation. Although the performance may not be able to kill the display card in seconds, it is already quite strong. Moreover, because their power consumption is far lower than that of the display card, it is easier to form scale and the electricity cost is also lower, It is difficult to compete with these excavators. And this kind of machine will be more expensive
there are many stream processors in GPU of graphics card. For example, the old HD5770 has 800 stream processors, which is equivalent to 800 computing cores. In recent years, the mainstream high-end graphics card has more built-in stream processors and more powerful computing performance. Using GPU for mining operation, the stream processor is used for parallel operation, and the mining program also optimizes the GPU parallel operation, so the operation efficiency is particularly high, and the efficiency of bitcoin mining has been greatly improved
the number of CPU cores is relatively small. At present, the number of the most powerful mainstream desktop processor cores is no more than 10 or 20 (many are logic cores virtualized by hyper threading technology), and the parallel computing power is far less than that of GPU.
excessive overclocking
e to the use of components with higher technical parameters, some graphics cards have excellent overclocking capability, so many players advocate overclocking graphics cards to improve performance. However, there are both advantages and disadvantages. Overclocking can also lead to a significant increase in the heat of the chip. When it reaches a certain level, it will cause the problem of splash screen and crash. Even if not, it will also cause instability in some applications, such as games. Therefore, overclocking must be moderate. 4

all oil holes on the machine and all rotating parts should be refueled with clean sewing machine oil every 4 hours. Other oils and unclean sewing machine oil should not be used, so as not to affect the service life of the machine
(2) regular maintenance and inspection
it is necessary to keep the parts clean, regularly check whether the temperature and sound of the rotating parts are normal, and repair them immediately if any problems are found, so as to avoid damaging the machine
generally, minor overhaul is concted once a month, and cleaning and major overhaul are concted once a half year. After being put into use for a long time, it should be cleaned and overhauled first
the thickness and use speed of the sewing material should be selected within the specified range, and it should not be overloaded or over speed.
bitcoin exists in the Internet, because it is essentially an encryption code, so in order to obtain bitcoin, we have to obtain it from the network in a certain way. Just like gold, it needs all kinds of machinery and equipment to dig. Bitcoin mining is also similar to gold mining. It also needs various machines and tools to obtain bitcoin. At the beginning, bitcoin could be g through the computer CPU, but as the value of bitcoin is graally disclosed and enlarged, many people graally improve the performance of mining equipment in order to obtain considerable benefits, that is, to the present ASIC mining machine. Now a miner is equivalent to dozens of computers. The mining ability of this miner is greatly improved, and the probability of obtaining bitcoin is also increased accordingly. However, the power consumption of the mining machine is too high. Most people leave it at home, and the income may not be able to offset the electricity charge. So mining machine mining, has graally become a small part of the financial strength of the game. This is not a good thing for bitcoin
therefore, based on this phenomenon, Xbit mining was born. Xbit mining is mainly based on the calculation power of the entity miner. The difference is that Xbit is equal to 1t calculation power and the power consumption is 60W. It is equivalent to lowering the threshold of participation in mining. Ordinary people also want to participate in bitcoin mining. There are certain ways
in general, if the financial strength and resource strength are strong, you can buy a large number of mining machines to dig bitcoin; Those with limited capital and resources can buy part of Xbit for mining, and finally get bitcoin. Specific choice of which way, mainly according to the owner's own situation.
Tianhe-1 uses 6144 Intel general multi-core processors and 5120 amd graphics acceleration processors, with a total memory capacity of 98tb. The bandwidth of point-to-point communication is 40Gbps, and the total capacity of shared disk is 1PB. The supercomputer system will be deployed in the National Supercomputing Center in Tianjin Binhai New Area as the business host. Tianhe-1 adopts AMD's ati4870 and Tianhe-1A adopts NVIDIA chip
