1. clock speed
The clock speed is also called the clock frequency. The unit is MHz, which indicates the computing speed of the CPU. CPU clock speed = frequency X frequency doubling coefficient. Many people think that the clock speed determines the CPU running speed. This is not only one-sided, but also a misunderstanding of the server. So far, there is no definit
CPU of Linux system and performance monitoringPerformance optimization is the process of finding bottlenecks in system processing and removing them. This article was translated by sanotes.net webmaster Tonnyom in August 2009 from the Linux System and performance monitoring series. This article is the first in a series that describes CPU performance monitoring.

In Hyper-V 3, the virtual machine CPU competition mechanism Windows Server 2012 is coming late. The latest Hyper-V 3 brings us more surprises, in the next three blog posts, we will learn about the virtual machine CPU competition mechanism. Part 1: CPU resources allocated to virtual machines; Part 2: Top CPU resources u
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.

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
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?

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

How to detect CPU Temperature Author: Anonymous Tutorial Source: The original site hits: 10190 update: 2008-8-20 as the weather slowly gets hotter, the computer's heat dissipation problem is a concern. Here I recommend a small software that can test CPU temperature core Temp. It is through the C
Computer use for a long time, it is inevitable that such a failure. In many computer failures, board card class appears the most likely. Although the CPU is an important part of the computer, but the probability of failure is relatively small, common CPU failures are roughly the following: thermal failure, restart failure, black screen fault and overclocking failure. Because the
All the time, I always thought that the CPU is really the combination of various logic gate devices as described in the book on the principle of computer composition in the past year. When you see nanotechnology, do you really think that you can make those devices so small? Until we saw the Intel CPU production process and AMD chip production process of the introduction can not help feeling, the original te
