9gpu mining machinery quasi system

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

2.

The miner is better

1. the electricity charge for mining with graphics card is very high, and the performance is not high, so it can't even earn the electricity charge

2. mining is an investment more than time and speed. We should try to dig more money in the shortest time. Therefore, the professional mining machines of BTC now stress the characteristics of simple operation, small footprint and low power consumption. For example, Yingtai has developed a professional mining motherboard with a computing power of 23.488g/hash, and the proct model is btc-24gh< br />

4. According to the current total computing power and the current growth rate of total computing power, it will take about 250 days to dig a bitcoin

5. GPU is the meaning of graph line processor, the original design intention is to do graphics computing. GPU chip is essentially a collection of many small CPUs for image processing. Of course, each CPU can also do general operations such as addition, subtraction, multiplication, division or non shift jump, so it can also be used for mining. When GPU is mining, it wastes less chip area and power consumption than CPU, so mining efficiency is higher than CPU
What about ASIC? It is a more optimized circuit than the CPU mentioned above. There is no specific definition, but there is a rule in the field of chip design: the more general computing platform, the less efficient it is to complete specific computing. ASIC is the most dedicated computing platform. If we understand this, we can come to such a basic conclusion: in the mining field, if we use the computing power proof mechanism, as long as the CPU can dig, ASIC can dig. No matter what algorithm is used, ASIC can dig. There is no reason that CPU can dig, but ASIC can't, So the biggest difference between GPU and ASIC is their specific computing power.

6. Before calculating the friction force, we must first analyze the motion of the object to determine whether it is static friction or sliding friction. If it is sliding friction, we can use the formula F= μ N calculation, where μ Is the coefficient of friction; If it is static friction, it is generally based on the motion of the object (static, uniform motion, or variable speed motion), In order to determine the direction of sliding friction, it is necessary to grasp the judgment basis of "the direction of sliding friction is opposite to the relative movement direction of the object". The specific method is: first select the object subject to friction as the research object, and then take the object directly in contact with the research object as the reference object, Find out the velocity direction of the research object relative to the reference object, then the direction of the sliding friction is opposite to the direction of the relative velocity.
the basis for judging the direction of the static friction is: "the direction of the static friction is always tangent to the contact surface, and is opposite to the direction of the relative motion trend of the object". The specific method is: firstly, select the object subject to static friction as the research object, Then, the object in contact with the research object is selected as the reference object, and the velocity direction of the research object relative to the reference object, that is, the direction of relative motion trend, is judged by assuming that the contact surface is smooth. Then, the direction of static friction is opposite to the direction of relative motion trend

7. The essence of mining machine is different
the essence of BTC / eth mining machine is data computing equipment
mining has developed from the initial personal computer mining, video card mining and personal mining machine mining at home to the cluster and professional large-scale mining. No matter from the initial CPU mining, GPU mining, or later FPGA mining, ASIC mining, large-scale cluster mining, its essence is to focus on improving the data computing capacity of mining equipment. The main internal parts of the mining machine are the power calculation board or graphics card, and the large cooling fan
the essence of IPFs miner is data storage device
the different essence of miner makes the configuration characteristics of storage miner very different from BTC / eth miner. The storage miner mainly used for data storage does not need too much computing power, that is, the performance of CPU is not required to be too high, and the memory capacity is suitable, but it needs a large capacity of storage space. That is to say, the density of hard disk per unit space should be large, and as many hard disks as possible should be equipped. At the same time, the I / O performance of data storage should be high, and the bandwidth channel should be as high as possible. Because of the special requirements of data storage, mining machine must be stable, safe and not easy to damage
filecoin officially announced that GPU is needed for mining. Although it means that computing power resources are also needed, the miners who use GPU get rewards for mining blocks. Most of them don't participate in mining blocks and only provide storage devices. They don't need GPU and can mine as long as they have a hard disk

8. Do you mean virtual currency like BTC and counterfeit currency like LTC? At present, the country has not explicitly stipulated that the Internet virtual currency is illegal, nor has it been recognized as legal. Now it belongs to the gray zone. However, many foreign countries have used virtual currency to trade goods, because virtual currency is used for Internet, and there is no need to convert us dollar or euro. If you feel satisfied, please give me some dog money

9. This is what Tianhe-1 and Tianhe-1A do.
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

1. Take No.528 from the west railway station, pass 11 stops, and reach Yuhong intersection station

2. Take no.615, pass 3 stops, and reach Fuqin market station

3. Walk about 40m to reach the vocational ecation center
