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

During system maintenance, you may need to check the 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 and in dialog mode. The top-based command can be used to control the display mode.

In linux, you can use top or vmstat to view the system's CPU usage. In most cases, the CPU usage is accurate, but in real-time linux systems with high time precision, the CPU usage measured by top may be inaccurate. The following uses the top principle and real-time linux instances to analyze the usage of top in the real-time system. When calculating the

Getting started with Linux: How do I know which CPU kernel the process runs on? Problem: I have a Linux Process running on a multi-core processor system. How can I find out which CPU kernel is running this process? When you run a high-performance HPC (high-performance computing) program or a program that consumes a lot of network resources on a multi-core NUMA processor,

The basic idea is how to make the CPU hyper-threading or multi-core more balanced and efficient use. We know that there is always a CPU dedicated to responding to the NIC interrupt requests. If the network request package is very large, A single CPU may not be able to handle the problem. Therefore, you need to activate multi-core or hyper-threading to distribute

We know that all servers are now multi-core, and the latest intel sandybridge is the NUMA Io structure. Taking the NIC as an example, that is to say, the PCI slot is not connected to the CPU through a bridge like westmere, currently, SNB directly links PCI to the CPU. Sometimes when we test performance, we can see that the performance is high or low. The reason is hard to find and confused. Next I will lis

In the previous tutorial to see the CPU temperature, we share a lot of CPU temperature detection software, including: Cpu-z this software. In addition to having the ability to view CPU temperature, Cpu-z has a lot of functionality. In today's tutorial, we will give you a sto

Psutil is a cross-platform library that makes it easy to get the process and system utilization (CPU, memory, disk, network, etc.) information of the system running, mainly used for system monitoring, analyzing and restricting the management of system resources and processes, which implements the functions provided by equivalent command line tools, such as Ps,top,lsof, Netstat,ifconfig,who,df,kill,free,nice and so on. Supports 32-bit, and 64-bit Linux

From: http://www.icembed.com/info-19346.htm With the rapid development in the field of digital communication and industrial control, dedicated Integrated Circuits (ASIC) are required to have higher and higher functions, lower power consumption, and shorter production cycle, these all pose a huge challenge to the chip design. The traditional chip design method can no longer meet the complex application requirements. 1 Introduction SOC (system on a chip) is becoming increasingly popular with

The Windows Task Manager can view the CPU usage.The CPU runs continuously. As long as the CPU is powered on, the command is executed, and the NOP operation is executed even if nothing can be done. Therefore, the low CPU usage of Windows does not mean that there is nothing to do with the

32-bit CPUs contain the following registers: 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 RegisterData 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

How to correctly identify the number of CPUs and the number of cores with Linux commands Cat/proc/cpuinfo |grep Physical |sort-u |wc-l This command is to view the number of CPUs. Basis of judgment:1. CPUs with the same core ID are Hyper-threading of the same core.2. CPUs with the same physical ID are the same CPU-encapsulated thread or cores.English version:1.Physical ID and Core ID is not necessaril

Recently, a timestamp system was written to record some important time nodes of each module in the system. Getting the kernel escalation timestamp is through the process polling, but found that the process in the actual running CPU utilization is very high, which is a dead loop in reading the device files, this thought is due to read system calls too frequent reasons.Then write a test program, which is just an empty loop. It turns out that the
