Testing computer computing power

1. There is no way to estimate the total computing power of computers all over the world, because everyone's computers, including CPUs, graphics cards and memory, are different. To calculate the total computing power of the world, I don't think anyone can do it.
2. Do you say PC? In my opinion, any computer has the ability of parallel computing. It depends on how you define it. Parallel computing and distributed system are both computing methods, not hardware specifications
each task in your operating system has a process, and each process is composed of many threads. If you've ever had an operating system class, you should have met multi threads programming. You let different threads cooperate to complete the same task, which is actually called parallel computing and distributed processing.
you can see that the projects of those parallel computing classes also run algorithms with ordinary computers, The key point is that you will simulate this environment. Just like those who run network algorithms use socket to simulate, they also use a PC to simulate the network of N workstations.
if you say multi-core CPU, First of all, you don't have access to the firmware of ordinary motherboards. So you have to buy a programmable board of general purpose, But if you want to buy a multi-core basic, you can't find it... Only in the laboratory can you have it... Even if you find it... I think that the money for that board is estimated to be several times of the tuition for you to go to graate school and then enter the laboratory...
in a word, if the software is implemented, today's PC should have no problem, As for how to start parallel computing mode, you need to read the datasheet of this board.
I don't agree with the above saying that there must be two cores, People with two brains can do parallel. But the left brain and the right brain of one brain are also parallel. When refining different neurons, the other completely independent neuron is also parallel. Parallel is a way to solve problems, an idea. Parallel computing was first proposed in 1912. I can't remember when the multi-core processor appeared, But after 2000, at least

3. No, if multiple programs are running at the same time, the al core 2.2g is better than the single core 4.4g. If it is a single task, the 4.4g single core is certainly better. Now u is developing towards multi task operation. For example, if you watch a movie with 4.4g, it's no problem. If you open a few web pages or games at the same time, the cup will happen, but the al core 2.2g is different.
4. There are different instruction sets.
if you play 360 games with PC through simulator,
you are in a circle.
you should understand the story of tortoise and rabbit race

5. Maybe Master Lu's program is stuck. You can right-click the taskbar and choose to start the task manager to end the process of Master Lu.
6. In 1946, the first electronic computer appeared in the world. Today, it has been more than 30 years. In this short time, it has made great progress. The computing power of ordinary computers has reached 40 million times per second, faster than the speed of calculation and abacus
Why do computers work so fast
because the arithmetic unit and controller in the electronic computer are composed of bistable circuit and various "gate" circuits; In other words, they are calculated by using the high-speed transmission characteristics of electricity. We know that the transmission speed of electricity is 300000 kilometers per second, which is very fast. Therefore, the computing speed of the electronic computer is very fast< Secondly, the operation of electronic computer is very simple. No matter how complicated the problem is, as long as the personnel design the calculation program in advance and send the calculation program together with the original data to the computer, it can automatically calculate the original data step by step according to the manual program. Each operation is very simple. For example, to add, you only need to do 1 + 1 = 10, 1 + 0 = 1, 0 + 1 = 1, 0 + 0 = 0. There are only four cases (subtraction, multiplication and division are the same). Such a simple calculation, primary school students can quickly work out. Because the calculation is simple, the arithmetic unit can also be very simple; In other words, the bistable circuit and "gate" circuit are needed less, and the electronic path is also less, which makes the operation speed faster.

7. Hello, your situation is e to the driver version problem, because OpenCL in the driver does not support these. So every time the detection will appear "display driver stopped responding, and has been restored" situation, it is recommended that you can upgrade win10 system.
8. Operation speed, you can detect the CPU's double precision floating-point operation ability. The number of threads only determines the CPU's processing efficiency for parallel multitasking, but has little effect on the speed of operation
9. Unknown_Error
10. Don't break the law. Don't worry. Have you ever heard of the person who was jailed for this? I wish you the best!
