CPU information in Linux (cpuinfo, multi-core, multi-thread)
In Linux, how do I know the CPU details in detail? Of course, it is checked through CAT/proc/cpuinfo. But for example, how many physical CPUs, cores, and threads are there?After checking, my development machine is a physical CPU, 4-core 8-thread, Intel (r) core

generation of the Intel function library. Intel publishes an IPP library of functions for each new multi-core processor, designed for multi-core architectures, and provides a library of scheduling optimizations for math, signal processing, audio and video, image processing and encoding, string, and cryptography.

a luxury device? Chip was once a high-tech technology that we couldn't match. What about now? However, we should also see that some companies continue to possess high-tech technologies, such as Intel, Microsoft, Oracle, and Synopsys. It is easy to design a simple system, but it is difficult to design a stable, efficient, and rarely-hosted server. The low-end switch chip in the switch is nothing, but the design of the 16-
packaged with two full CPUs and connected to the same front-end bus. It can be said that AMD's solution is the real "dual-core", and Intel's solution is "dual-core".
It can be assumed that such a two core will inevitably produce bus scramble, affecting performance. Not only that, but also the future of more core inte

Just this year, both giants have reformed their products, introducing the latest architecture of processors, AMD with the AM2 architecture processor as the weapon, but the new architecture of the processor has not revolutionized the performance of the new processor is not improved; instead, Intel's newest core architecture processor, Whether from power consumption or performance, there h
I will repost the incisive analysis of a patriotic man to you. I hope you will be able to support Chinese goods more soon! Over the years, the Chinese people have been helpless in the information field and have been saddened by their inability to master core technologies. They also know that this situation is extremely dangerous and they are very worried about national defense security. Under such circumstances, there have been several different attit
Intel, the performance difference is very large.If you use A7, the eight cores are not as good as the two cores of A15. From a fluent point of view, the frequency and type of a single core is more important, the core number of more useless.Second, memory bandwidth is actually more criticalFor smartphones or tablets, it is SOC, which means that the display
to develop the macro division method of parallel blocks and divide them from the entire software system, instead of performing parallel decomposition for some local programs and algorithms, because local programs are usually difficult to break down into dozens of tasks. Another coping strategy is at the tool level, that is, the compilation tool can assist in manual Parallel Block decomposition and find a good decomposition solution. Intel has made so

The chipset (chipset) is the core component of the motherboard. If the central processing unit (CPU) is the heart of the entire computer system, then the chipset will be the torso of the entire body. In the computer industry, the design chipset is called "Core Logic". The Chinese meaning of core is central or central. The literal meaning of light is sufficient to
As the. NET Core 2.1 was officially released, the Microsoft team mentioned the performance gains in. NET Core 2.1 in the blog. This reminds me of the performance contrast between go and. NET Core 2.0, which was made by the Go language Iris MVC Framework author last year, when Iris performed at least 1 time times more than. NET

SMT allows multiple threads on the same processor to run concurrently and share the execution resources of the processor through the structure status on the replication processor, allows you to process excessive data volumes in a wide-emission or out-of-order manner to the maximum extent, improve the utilization of processor computing components, and reduce the access memory latency caused by data-related or cache miss.

Multi-core server server processors in 2005 by AMD Dual-core Opteron, Intel Corporation dual-core Xeon Paxville, Sun Company 8 nuclear UltraSPARC T1 kicked off, in 2006, The further support and optimization of the operating system and application software for multi-core pro
Multi-core computing-some things that should be known at the CPU and memory layers during multi-core programming. Try to find the essence of multi-core coordination.
Here we will basically refer to the x86 system and then simplify or modify it as needed.
First look at the various caches:
In order to solve the imbalance between Access Memory and CPU operations,
the nuclear process, and the time of the two cores is not the same.I only assigned 1 CPU cores to Iometer's related tasks in the Task manager, so I got all the normal results. It seems that my guess is correct. It seems that the time of AMD64 each core is somewhat different. When booting, you should start a core, start another core, and then both cores faithfull

waiting for user input, or waiting for some events to occur (sending an I/O Request to wait for I/O response), or actively enters the Sleep state (such as Sleep ()).
In a refresh cycle in the task manager, the ratio of the CPU busy (executing the application) Time to the total time of the refresh cycle is the CPU usage. It displays the average CPU usage statistics for each refresh cycle. We can write a program to make it busy and idle for a while during the refresh time of the task manager. by
