Back cover calculation (estimate)

One day equals 24*60*60 estimate of * 4 = =10^5 (100k)

Sansen 10 000 000 000=10^10

Which means that one day in Sansheng III is equivalent to a second of the day.

Now the average PC CPU can perform operations for 10^9 (1G) integer (floating point) operations (1) Flops (now it should be common to do several times).

Tip

The clock frequency of the CPU core (CPU clock speed), which is the main frequency of the 1 CPU. What is commonly referred to as a CPU is how many MHz, and this number of MHz is "CPU frequency." Many people think that the CPU clock is the speed of its operation, it is not. The CPU frequency indicates that the speed of the digital pulse signal oscillation in the CPU is not directly related to the actual computing ability of the CPU. Because the main frequency does not directly represent the speed of operation, so under certain circumstances, it is likely that the high frequency of CPU actual operation of the phenomenon of low speed.

2 FLOPS (that is, the number of floating point operations per second, peak per second) is the abbreviation for the number of floating point operations performed per second (floating-point operations per second). It is often used to estimate the performance of a computer, especially in the field of scientific computing, where large numbers of floating-point operations are used. It is because the flops of the tail of the S, representing the second, rather than the plural, so can not be omitted.
