P106 calculating power

1. computing power refers to computing power. 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", Unit is written as hash / s, which is the so-called workload proof mechanism pow (proof
of
work)
What does 1p mean
first of all, 1p computing power is equivalent to about 1.05 million g, which means that if you have 1g computing power of the whole network, you can get almost 1.05 million of bitcoin output of the whole network. According to the output of 3800 bitcoins per day, we can see that the daily income of 1g of computing power has dropped to 0.0036 bitcoins, which is about 2.7 yuan according to the current market price. If the electricity cost and mining machinery hardware cost are included, the profit is almost gone
secondly, 1p's whole network computing power seems amazing, but in fact, in a year's time, you will think it's just a pediatrics, because cointera will launch 2p miner in December, and bitmine will launch 4P miner in March next year. If these companies are not put in biochemical weapons by Syria, it should be expected that bitcoin's whole network computing power will reach more than 10p in a year's time, By then, 1g of computing power will only be able to dig 0.00036 bitcoins a day.

2. In January 2013, Avalon released the 60g / s miner specification and accepted the booking. In January 2013, Avalon delivered the world's first commercial bitcoin ASIC miner, and the core developer of bitcoin network, Jeff
garzik, was fortunate to be the owner of the first commercial ASIC miner.
the most difficult mining problem was 0, and the computing power was about 2p at the beginning of 2013, and now it has reached 100p

Supercomputing Center's computing services are generally charged. You can go to the 10th power to learn about it. At present, the 10th power has launched free computing services

the tenth power cooperates with computing earth to launch the world's largest distributed computing resource computing power supply platform, providing free computing power support for projects requiring a large amount of computing power output. The computing power bank can provide idle computing power of personal devices worldwide, providing computing power support for world-class scientific research projects, involving mathematics, physics, chemistry, life sciences, astronomy and other fields

so far, the peak computing power is as high as 100p, which is equivalent to the computing power of tianhe-2, the world's fourth largest supercomputer, and can meet the needs of all computing power projects on the market

4. Computing power (also known as hash rate) is a measure of bitcoin network processing power. That is, the speed of computing hash function output for computer (CPU). 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 the computer's 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 the so-called proof of work mechanism (POW)

recently, bitcoin's network computing power has entered the era of P computing power (1P = 1024t, 1t = 1024g, 1g = 1024m, 1m = 1024k). In the ever-increasing computing power environment, the arrival of P era means that bitcoin has entered a new stage of arms race

computing power is a measure of the total computing power of the unit that generates new blocks under certain network consumption. The single blockchain of each coin varies with the time required to generate a new transaction block.

5. Apple's serial number does not contain the letter O, only the number 0. After modification, the serial number you provided is still invalid. Check whether the serial number record is correct. Otherwise, it does not belong to Apple procts
confirm whether your phone is iPhone 4 8GB black. Otherwise, it can be confirmed that the machine is a high imitation machine. It's not a real machine
the beginning of serial number c3k is the official renovation, which is provided for after-sales service to replace the faulty machine.

6. The occupancy rate of GPU and video memory has nothing to do with the display
it mainly depends on the changes in the settings of the graphics card and the game, and it doesn't
focus on whether the vertical synchronization is turned on or off, as well as the settings of resolution and image quality
full load is sometimes a good thing, indicating that the CPU has no bottleneck
indicating that the utilization rate of GPU is high

7. Motor torque calculation
motor "torque", unit is
n & 8226; M (nm)
the formula is
t = 9549
*
P
/
n

P is the rated (output) power of the motor, the unit is kilowatt (kw)
denominator
is the rated speed
n
the unit is RPM
(R / min)
P and
n can be found directly from the
motor nameplate.

1bar=1.02kg/cm2 Bar is a unit of pressure. At least we need another area to calculate the force

about the pressure unit bar:

bar (symbol bar), millibar (symbol mbar, also known as MB) are. They do not belong to the international system of units or the centimeter gram second system, but they are accepted to be used in conjunction with the international system of units. Because bar is similar to atmospheric pressure, it is widely used to describe pressure. It is legally recognized in the countries of the European Union

1 bar (bar) = 100000 PA (kPa) = 100 kPa (kPa) = 1000000 dyn / cm2 (dyne / cm2)
1 mbar (mbar) = 0.001 bar (bar) = 0.1 kPa (kPa) = 1 HPA (kPa) = 1000 dyn / cm (dyne / cm2)
