How to arrange computing power
compared with the stimulation of high returns by making contracts, cloud computing power is more stable and conservative; Compared with hoarding money, cloud computing power can better experience the original pleasure of mining. It can be said that the purchase of cloud computing power is equivalent to the layout of a small ecosystem. Every day, you just need to pay the electricity fee, management fee and operation and maintenance fee. Instead of the rise and fall of the currency price for a while, you can calmly give the income to time and technology. Not only that, the cloud computing business launched by 58coin exchange this time has prepared a lot of cost-effective services for investors.
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
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
unit of force
1 KH / S = 1000 hashes per second
1 MH / S = 1000000 hashes per second
1 GH / S = 1000000000 hashes per second
1 th / S = 100000000000 hashes per second
1 pH / S = 100000000000 hashes per second
1 eh / S = 100000000000 hashes per second
The development of single CPU can not meet the needs of practical applications, and the AI era must rely on parallel computing. At present, the mainstream architecture of parallel computing is heterogeneous parallel computing platform. If you need the service of computing power, you can go to the tenth power
still need to do more dead and alive questions. It is far from enough to put all kinds of living and dying rudiments into actual combat. Many of the ways and muscles of go are based on the experience of chess sense, rather than on a temporary basis
when I was a child, when I was learning chess, I had to brush up a thousand questions about life and death. The so-called improvement actually allows you to subtract the shape and path of both sides, and remove the path that does not conform to the shape rules. There are many basic theorems, such as the seven dead and eight alive when climbing the second way, the calculation of public Qi when not returning, the Golden Rooster being independent, taking off his boots, killing each other, and the harmony between big eyes and small eyes. In all kinds of corners, there are four kinds of variants: big pig mouth, small pig mouth, golden cabinet corner and plate corner
there are many things that need to be done. You'd better summarize the rules yourself. For example, I'm going to tell you a few skills of killing chess. Try to rece the eye position of the opponent first, and then consider killing the eye; Another example is the enemy's key points, my key points, the enemy's live chess, I go first, so that the other side can not live. Many rules will form a kind of fast-food memory if you don't practice them, and even it's not concive to summarize the problems you encounter.
cube is volume: edge length x edge length x edge length.
