How many million Ethereum processors per second

2. In fact, the rise and fall of digital currency is a normal situation. The key is to see whether you are optimistic about its long-term value. Relatively speaking, if the long-term value is worth investing in, then the short-term decline can be ignored. At the same time, if you don't know much about digital currency users, it is recommended to choose a reliable and good platform for investment. The investment period needs more than six years, Word of mouth should always be good, you can take a look at AEX, fire coin these two, but also more reliable, you can also understand their own network first

3. I don't think I'll ever get back to this

4. Ethereum is a blockchain. Compared with bitcoin, it can increase smart contracts, complete Turing and faster network speed. Etherem has a lot of block chain procts with regional centralization, such as digix, gold Internet of things and so on.

5. mining doesn't need a good CPU, does it? CPU algorithm mining is too low, mining is mainly using graphics card mining

6. The following table records the history of computer development in China:
in 1958, the Institute of computing of the Chinese Academy of Sciences successfully developed China's first mini tube general-purpose computer 103 (model 81), marking the birth of China's first electronic computer< In 1965, the Institute of computing, Chinese Academy of Sciences successfully developed the first large-scale transistor computer 109b, and then launched 109C, which played an important role in the two bomb tests

It is a four processor vector machine with shared main memory. Its vector central processor is designed by using small and medium scale integrated circuits, reaching the international advanced level in the middle and late 1980s. It is mainly used for medium range weather forecast< In 1993, the national intelligent computer research and Development Center (later founded Beijing Shuguang computer company) successfully developed shuguang-1 fully symmetric shared memory multiprocessor, which is the first parallel computer designed and developed in China based on a general-purpose microprocessor chip based on VLSI and standard UNIX operating system

Dawning 1000 is similar to the architecture and implementation technology of massively parallel computers introced by Intel in 1990, and the gap with foreign countries has narrowed to about five years
in 1997, National Defense University of science and technology successfully developed the galaxy-iii 10 billion times parallel supercomputer system, which adopts the scalable distributed shared memory parallel processing architecture and consists of more than 130 processing nodes. The peak performance is 13 billion floating-point operations per second. The comprehensive technology of the system has reached the international advanced level in the mid-1990s
from 1997 to 1999, Dawning company launched dawning 1000A, dawning 2000-i and dawning 2000-ii super servers with cluster structure in the market. The peak computing speed has exceeded 100 billion floating-point operations per second, and the machine scale has exceeded 160 processors.
in 1999, Dawning company launched dawning 1000A, dawning 2000-i and dawning 2000-ii super servers with cluster structure, Shenwei I computer developed by the National Research Center of concurrent computer engineering technology has passed the national acceptance and has been put into operation in the National Meteorological Center. The system has 384 operation processing units, and the peak operation speed is 384 billion times per second
in 2000, Dawning company launched Dawning 3000 super server with 300 billion floating-point operations per second< In 2001, the Computing Institute of Chinese Academy of Sciences successfully developed China's first general-purpose CPU -- "Loongson" chip
in 2002, Dawning company launched "Longteng" server with completely independent intellectual property rights. Longteng server adopts "loongson-1" CPU, adopts the server dedicated motherboard jointly developed by dawning company and Computing Institute of Chinese Academy of Sciences, and adopts dawning Linux operating system, The server is the first proct in China to fully realize its own property rights, and will play an important role in national defense, security and other departments
in 2003, dawning 4000L, a million times data processing super server, passed the national acceptance, once again setting a new historical record of domestic super server, making the domestic high-performance instry to a new level

7. Blue gene / L is a super computer with 33000 processors. The final blue gene / L system was submitted to Lawrence Livermore National Laboratory in the first half of 2005. The prototype blue gene / l can perform 70.72 trillion calculations per second. According to IBM, when it's finally assembled at Lawrence Livermore lab, blue gene / l will be a system with 130000 processors, with an estimated peak speed of 360 trillion times.

8. The calculation of computer is carried out by CPU. The most basic operations are arithmetic operations, namely +, -, *, /. The values involved in arithmetic are different from those in theoretical mathematics, because "one foot of the hammer takes half of the day, and it will last forever.". In the computer internal expression can only be accurate numbers, so infinite decimal is impossible to express. This is the first point: the value of computer is different from that of human contact.

9.

At present, the CPU speed of most home computers is about 5 billion calculations per second

most of the time, the number of CPU runs and calculations per second is measured by the flops value. Nowadays, most CPUs have a "floating point unit" (FPU) specially used to handle floating-point operations. Therefore, what flops measures is actually the execution speed of FPU

1GHz is billion operations per second. If two floating-point operations can be completed in each operation, it is called 2G flops (two billion floating-point operations per second). At present, household al core computers can usually achieve the level of about 5 billion operations per second (2 * 2.5GHz), and the floating-point performance is about 10 billion floating-point operations

{rrrrrrr}

extended data:

flops conversion:

one MFLOPS (megaflops) is equal to one million (= 10 ^ 6) floating-point operations per second,

one gflops (gigaflops) is equal to one billion (= 10 ^ 9) floating-point operations per second,

a tflops (teraflops) is equal to one hundred billion (= 10 ^ 12) floating-point operations per second,

a PFlops (petaflops) is equal to one hundred billion (= 10 ^ 15) floating-point operations per second,

an eflops (exaflops) is equal to one hundred (= 10 ^ 18) floating-point operations per second,

a zflops (zettaflops) is equal to 100000 floating-point operations per second (= 10 ^ 21)

At present, the computing speed of China's tianhe-2 supercomputer is 30.65pflops
