the output device.Output device: A device that outputs information from a computer to a user. Commonly used input devices are: monitors, speakers, printers, projectors and so on We buy computer, if only keyboard mouse, monitor, speaker, we can play computer? Definitely not. So in fact, the computer chassis is the real work of the device, input just used to let us and the computer chassis to do the interaction.What's inside the chassis? Let's take a look at the following picture:Let's see

In Linux, you can view CPU and memory usage during system maintenance. You may need to view CPU usage at any time and analyze the system status based on the relevant information. In CentOS, you can use the top command to view CPU usage. After the top Command is run, the CPU usage status is displayed in full screen mode

first, the CPU cache structureCPU speed is much higher than memory (that is, if only CPU and memory factors are considered, the performance of the program is often limited by memory access speed, memory access and operation), in order to reconcile the CPU and the difference in the speed of the internal, the CPU has bee

Layer-3 Ethernet switches are quite common, so I have studied the problems related to the CPU packet sending and receiving of layer-3 Ethernet switches. I would like to share them with you here, hoping they will be useful to you. Layer-3 Ethernet switches are developing rapidly. On the one hand, bandwidth and switching capacity of network devices are greatly increased, and the types of protocols supported by devices are also increasing with the increa

Why is the server so slow? CPU, RAM, and disk I/O resources are exhausted, and ram is used up Machine running is slow because it consumes too many system-specific resources. The main resources of the system include CPU, RAM, disk I/O, and network. Excessive use of any of these resources puts the system in trouble. However, if you can log on to the system, you can use a large number of tools to determine the

Cpu display information that you may not understand in CentOS command top When using the top Command, the following line is displayed: What are the meanings of each value in it? I was asked this question today and found that the answer is not very clear. Sure enough, the most frequently used top commands every day are still unknown... Shame... So I checked some information:Official explanation Cpu (s) indi

Tags: priority GitHub official item CTO how RTU iowait RelatedAdd by Zhj: Here's a good explanation of what WA means in the top command, and we know that when Io is blocked, the operating system changes the process to a blocking state, and the CPU is scheduled to run other processes.When the CPU is idle, it checks for blocked IO (disk or network), and if so, it is WA; if not, that is the real idle. In the t

0. Why write this blogThe top or PS of Linux can see the CPU utilization of the process, so why do you need to know this detail? There are three reasons for writing this article:* Want to be able to get process CPU utilization in a script in a "non-blocking" way * PS cannot get CPU utilization at the current time of the process; top takes at least 1 seconds to ge

Problem: I have a Linux process running on a multi-core processor system. How can I find out which CPU kernel is running the process? The affinity of Cpu/memory is one of the most important factors for maximizing performance when you run HPC (High performance computing) programs that require higher performance on multicore NUMA processors or programs that consume network resources very well. Scheduling

Linux is available under the top, PS command to check the current CPU, mem usage. Here's a simple example:First, using PS to view the process of resource consumptionPs-auxWhen you view the process information, the third column is the CPU check-in.[Email protected] utx86]# Ps-aux | grep my_processWarning:bad syntax, perhaps a bogus '-'?

You will see this line when you use the top command:What are the meanings of each of these values?Asked this question today, I found that the answer is not very clear. Sure enough, every day with the most top command has not been well-acquainted ... Ashamed... So I looked up some information:Official explanationThe CPU (s) represents the CPU information. The meaning of each value is:Us:user

Basis of judgment:A physically encapsulated CPU (judged by physical ID) can have multiple cores (differentiated by Core ID).Each core can have multiple logical CPUs (judged by processor).One core implements this core's own hyper-Threading technology through multiple logical CPUs.The CPU cores entry contains the number of cores in the same physical package.The siblings entry lists the number of logical proce

High-speed cache of CPU is generally divided into level-1 cache and level-2 Cache. More CPUs now provide level-3 cache. When the CPU is running, it first reads data from the first-level cache. If the read fails, it reads data from the second-level cache. If the read fails, it reads data from the memory. However, the gap in the clock cycle between the CPU and the
