Comparison of bitcoin miner graphics card
2. Modern multi-core CPU aims at instruction set parallelism (ILP) and task parallelism (TLP), while GPU is data parallelism (DLP)
3. GPU often has a larger bandwidth of memory, that is, the so-called video memory, so it will also have good performance in high throughput applications
4. CPU is a general-purpose operation. In short, it means brainless calculation and violent calculation. Whether it's 100 children sharing apples or simulating the earth, it can be decomposed into the most basic calculation of 1 + 1 = 2. GPU is specially designed to deal with high-order mathematical algorithms, such as calculating the relative positions of light source, object, viewpoint and shadow, which requires trigonometric functions to be piled up. The bitcoin digger uses SHA-256, a secure hash function invented by the US National Security Agency, which is generally used for password encryption and decryption. This algorithm can perform a large number of 32-bit integer right-rotate operations, which is very suitable for GPU which is good at large-scale concurrent computing and password cracking.
Starting from the essence of bitcoin, the essence of bitcoin is actually a special solution generated by a bunch of complex algorithms. A special solution is one of the infinite (in fact, bitcoin is finite) solutions that can be obtained from the equations. Every particular solution can solve the equation and is unique
why use graphics card to mine
compared with the complex computing of CPU, GPU used by graphics card is used for general computing. So it can stack hundreds of stream processors awesome. Each stream processor is like a small CPU. Although its ability to run complex programs is far from the power of CPU, it can not support many processors, so the actual performance, especially the single precision floating point performance is much stronger than that of CPU. p>
the actions in bitcoin can be considered as the use of graphics card to do continuous general computing, and the computational complexity is relatively low and quite repetitive. The stream processor used by graphics card is just suitable for such an algorithm. It's like constantly solving equations. The graphics card is 2000 middle school students, while the CPU is 8 math doctors. Although the mathematical knowledge of the doctor of mathematics is far more than that of the middle school students, the speed of solving medium-sized equations such as virtual currency is certainly not as fast as that of 2000 middle school students
so we used graphics card to mine virtual currency at the beginning. After that, someone developed a specific algorithm to make the stream processor of the graphics card greatly strengthen the virtual currency solution, which is the origin of the mining machine
home computer can't even earn back the cost of digging bitcoin
at present, the home computers all dig up the Leyte coin, because there is no special Leyte coin miner, so it should be able to earn money
hope to adopt.
for example, bitcoin, lightcoin, gold card, reborn coin, doggy coin, lightcoin, Ruitai coin, bitstock and other digital currencies can be downloaded from rich packages
but there is no wallet to download MLM or some direct selling coins
for example: Baichuan coin, Morgan coin, treasure coin, etc.
therefore, if the economic capacity permits, the facilities should not be simple and crude, and should meet the food hygiene standards. Convenient, fast, healthy and high-quality breakfast is the most expected< Second, pay attention to the diversification of characteristics
according to the reporter's investigation and interview, there are few varieties and colors of breakfast in our city, so it is difficult for diners to choose according to their own taste. Almost all kinds of "juice, fruit, bean curd, steamed stuffed bun, porridge, fried cake" have remained unchanged for decades. Due to monotonous operation, lack of innovation and proper variety adjustment, it can not meet the public's requirements for diversified breakfast varieties and different tastes. Therefore, it is the most important task for operators to develop new breakfast varieties with health, nutrition and hygiene< Some famous traditional breakfast shops can be renovated in time, and the dining environment can be comprehensively transformed to absorb the operation mode of Western fast food. After the transformation, the shops have advanced facilities and will attract more customers with a new look. In addition, we should constantly innovate in business varieties and service opportunities. Only with standardized operation and management, comfortable environment, reasonable price and considerate service can we win the favor of the public< Fourthly, chain operation should give full play to its advantages.
it is very beneficial to actively introce advanced new business forms and promote chain operation of breakfast market for expanding the scale of breakfast market, improving the organization degree of breakfast market, recing proction costs, forming scale effect and improving the circulation speed of breakfast food. It can give full play to the advantages of chain operation in organization mode and management, widely use advanced proction equipment and technology, actively develop new varieties of modern breakfast, improve service level, and speed up the construction of modern breakfast supply system< Five, the use of modern network technology
conditional breakfast business enterprises should make full use of modern technology, through the efficient and smooth information network, release the information of variety, service price and service mode, and carry out the service of telephone ordering and home delivery to meet the personalized consumption demand
comments: To sum up the skills of operating breakfast shop mentioned above is a close-up of my friends' experience in opening breakfast shop for many years. I hope it will be helpful to you
