60mh calculation
Graphics cards can't dig out bitcoin right now. Your calculation power is the calculation power of Ethereum. The calculation method is also wrong
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
under normal circumstances
1G=1000M
1GH=1000MH
1gh=1000mh
ch is transport helicopter
uh is general helicopter

MH-60 is improved from UH-60
in the process of using, the frequency converter and speed governor are often impacted by the surge current and voltage, which will seriously damage the performance and service life of the frequency converter and speed governor. Therefore, the input reactor should be installed in front of the frequency converter to suppress the surge voltage and current, protect the frequency converter and speed governor, prolong their service life and prevent harmonic interference, At the same time, because the frequency converter and speed governor are used in the speed regulation, high-order harmonics and waveform distortion are often proced in the speed regulation, which will affect the normal use of the equipment. Therefore, an incoming reactor must be installed at the input end, which can improve the power factor of the frequency converter, suppress the harmonic current, filter out the harmonic voltage and harmonic current, and improve the quality of the power grid.
1. It is recommended that users upload and maintain web pages through FTP, and try not to install ASP upload program
2. The calling of ASP upload program must be authenticated, and only trusted people are allowed to use the upload program. This includes a variety of news release, mall and forum programs, as long as the ASP can upload files to carry out identity authentication
3. The user name and password of ASP program administrator should be complex, not too simple, and should be changed regularly
4. To download the ASP program from the regular website, the database name and storage path should be modified after downloading, and the database file name should also have certain complexity. Try to keep the program up to date
5. Do not add a link to the landing page of the background management program on the web page
6. In order to prevent the program from having unknown vulnerabilities, you can delete the login page of the background management program after maintenance, and then upload it through FTP ring the next maintenance
7. Always back up important files such as database
8. Daily maintenance should be done, and attention should be paid to whether there are ASP files of unknown origin in the space
once it is found that it has been invaded, it is necessary to delete all Trojan files unless it can identify all Trojan files. When you hang up the horse, the address bar will be red.
