Summary of KVM Virtualization CPU TechnologyA NUMA technology introductionNUMA is a technology solution that solves the multi-CPU work, and we first review the technical architecture history of the multi-CPU work together. There are three main architectures for multi-CPU work, namely SMP MPP NUMA architecture. SMP MPP

In the analysis of the system, one of the first and most basic tools is often a simple measurement of the CPU utilization of the system. Linux and most unix-based operating systems provide a command to display the system's average load (loadaverage). [huangc@v-02-01-00860 ~]$ uptime 11:18:05 up for days , 1:17, one users, load average:0.20, 0.13, 0.12 Specifically, the average load value represents the average number of tasks that can be run with

Eliminate the user to the CPU overclocking caused by the burning, we are in the normal use of computers encountered CPU processor failure is not uncommon. In general, if the computer can not start or very unstable, we will be from the motherboard, memory and other easy to fail to troubleshoot the accessories, if the motherboard, memory, graphics, hardware and other accessories no problem, then the

Multi-core CPU A central processor has two or more cores! Pretty Head, with two or more brains! However, the running speed is not double that of a single-core CPU, because a single-core CPU is 100% running, and a dual-core CPU is 60% multiplied by 2 running. It requires three cores, 50% multiplied by three cores, 40% m

During system maintenance, it may be necessary to review the CPU usage at any time, and to analyze the system condition according to the corresponding information. In CentOS, you can view CPU usage by using the top command. After running the top command, the CPU usage status is displayed in full-screen mode, and will be in the dialog-using top-based commands, you

Do not know if you have no sense, nearly one or two years of DIY hardware field, the CPU water-cooled radiator has a trend of increasing fire. Search on the Internet to know that, at present many manufacturers have launched a CPU water-cooled radiator, including the mainland manufacturers of the figure. CPU water-cooled Radiator Why has the fire come

We just know the CPU frequency, the core number, two cache and other parameters can be, the higher the frequency of high-frequency operation, the core number of the more the better, two-level cache the more about good. For graphics cards too, we just need to know the graphics card frequency memory and brand, the main frequency is also the speed of the graphics card, the higher the better, video memory is the display performance of the graphics card,

To solve the CPU usage is too high, first of all, we should understand what is the cause of high CPU, we mainly from the software and hardware to start with: 　　1, the software caused by the high CPU utilization rate This is mainly related to system problems, such as the system is too bloated, open too many programs and computer virus Trojan, etc. will

Cause the CPU temperature is too high: First, the ambient temperature Virtual CPU Especially in summer, CPU idle is its temperature can reach more than 50 degrees, full-speed work is more than 70, although this kind of temperature can be accepted in a short time, but if used for a long time, it will affect the life of the

When flash is connected to the CPU, according to different data width, such as 16-bit nor flash (A0-A19), the processor address line to (A1-A20) shift left to 1. Why is it one-digit? From the perspective of software and CPU, an address corresponds to one byte, which is 8-bit data. This is for sure. Do not doubt this. For a specific device, its bit width is certain. The so-called Bit Width refers to "the sma

Almost no one knows about CPU when using computers, and everyone can talk about CPU. So have you seen what the CPU looks like inside? The following describes the internal CPU secrets. (1) Basic CPU Structure: CPU generally inc

CPU is the soul of a computer, determines the overall performance of the computer. Now the mainstream CPU is multi-core, and some use multithreading technology (hyper-threading, referred to as HT). Multicore may also be easy to understand, believing that a lot of players can say why. But what does hyper-threading really mean, what is the difference between a CPU

The various "Tasks" in the Linux kernel can see the kernel address space, so they also need synchronization and mutual exclusion. The synchronization/Mutex methods supported by the Linux kernel include: Technology Function Scope of Action Per-CPU variable Copy a piece of data for each CPU All CPUs Atomic operation Atomic read-Modify-write a counter to

The kernel often requests and frees a single page box. To improve system performance, each memory management area defines a per-CPU page box cache. All "per CPU" caches contain pre-allocated page boxes that are used to satisfy a single memory request made by the local CPU.Provides two caches per memory area and per CPU: a hot cache, which holds content contained

Do system operation, monitoring CPU is a frequent thing, then need to pay attention to what indicators?????Run Queue StatisticsIf you want to see how busy the CPU is, we can make a simple judgment by looking at the status of the process in the system, for example, by looking at the number of runnable processes and the number of blocked processes to CPU utilizatio
