Four data registers (EAX, EBX, ECX, and EDX)2 address changes and pointer registers (ESI and EDI) 2 pointer registers (ESP and EBP)Six segment registers (ES, CS, SS, DS, FS, and GS)1 Instruction Pointer register (EIP) 1 flag register (EFlags) 1. Data Register Data registers are mainly used to save information such as the operands and operation results, thus saving the time required to read the operands by occupying the bus and accessing the memory. The 32-bit

Each-CPU variable is an interesting 2.6 kernel feature. When you create a per-CPU variable, each processor in the system obtains its own copy of this variable.This may look like a strange thing to do, but it has its own advantages. you do not need to lock every-CPU variable because each processor uses its own copy. per-CPUVariables can also be stored in the cache

Linux CPU metrics Linux provides a wealth of commands to monitor CPU-related data, such as top and vmstat. Top is a dynamic display process, that is, you can press the key to continuously refresh the current status. If you execute this command on the foreground, it will exclusively occupy the foreground until the user terminates the program. More accurately, the top command provides real-time monitoring of

When we use the Windows XP operating system, the system slows down when we use it. When we look at "Task Manager", we find that the CPU usage reaches 100%. How did this happen? In this article, I will explain why the system resource usage reaches 100% from three aspects: hardware, software, and virus. CPU usage is usually 100%, and the main problems may occur in the following aspects: Nine possibilities of

Intro-----Usually when we write server code, we can improve the efficiency of the system scheduler by binding the current process to a fixed CPU core or thread binding to a fixed CPU core, and then paste the complete code below.```/************************************************* This routine explains the process, thread binding to a fixed CPU core running on* T

/ This article will describe some of the CPU cache related knowledge that a program ape or it practitioner should know Article welcome reprint, but reproduced when please retain this paragraph text, and placed on the top of the article Lu Junyi (Cenalulu) This article address: http://cenalulu.github.io/linux/all-about-cpu-cache/ Let's take a look at a mind map of all the concept

CPU as the core part of the computer, the frequency of failure is relatively low, in many cases, the failure of the processor is due to the motherboard problem. such as the following troubleshooting, really let the author cost some twists and pains. Failure performance: a compatible machine assembled for friends in 2004, using the Intel Celeron 1.7GHz processor, has been in use for two years, the most recent in a move, love Machine is unable to start

Now in the computer market you will be pleasantly surprised to find that the configuration of more than 1Ghz CPU computer has become the mainstream of the market. When the CPU is more than 1GHz, the maintenance of the hardware CPU becomes the first important event, if still not enough attention, will cause computer failure or even crash, burn.

A journey through the CPU pipeline Compilation: @ deuso_ict AsProgramPersonnel, CPU plays a core role in our work, so it is not helpful for programmers to understand how the processor works. How does the CPU work? How long does it take to execute a command? What does this mean when we discuss whether a new processor has 12 or 18 or even 31 pipelines? Applic

I/O bound indicates that the CPU performance of the system is much better than that of the hard disk/memory. In this case, the system is operating, and most of the situations are that the CPU is waiting for I/O (Hard Disk/memory) in this case, the CPU loading is not high.CPU bound indicates that the system's hard disk/memory performance is much better than the

1.Preemptive Scheduling CPU scheduling decisons may take place under the following four conditions:1. When a process switches from running state to the waiting state (for example, I/O request, or invocation of waif wait for the termination of one of the Child processes)2. When a process switches from the running state to the ready state, for example, when an interupt occurs3. When a process switches from the waiting state to the ready state, for exa

Generally, for processes that require a large amount of CPU computing, the higher the front-end pressure, the higher the CPU utilization. However, for I/O network-intensive processes, even if there are many requests, the CPU of the server may not be very good. At this time, the Service bottleneck is generally on the disk I/O. In a long view, the
