As the core component of the computer, the CPU (central processor unit) has been very mysterious in the hearts of users: in the minds of most users, it is just an abbreviation, they cannot even write all of it. In the eyes of some hardware experts, the CPU is at most a block of more than 10 square centimeters, with many feet, the CPU core is less than 1 cm² large

Physical encapsulation of the CPU, a physical package using a separate CPU physical slot, sharing power and fans;CPU Physical Core: Encapsulates multiple independent CPU cores in a physical package, each with its own complete hardware unit.CPU Logic Core: A CPU physical core

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

Believe that a lot of computer users are too high CPU temperature problems, then, many netizens will ask, in the end, how much CPU temperature is normal. And a lot of tutorials on the Internet, the desktop computer CPU is too high to solve the problem, then, the laptop CPU temperature is too high to do? In today's tuto

This blog post focuses on the features and functions of the CPU registers around the base part of the registers in the 80x86 CPU.ObjectiveFirst, let's introduce the history of Intel CPUs.Intel CPU Series, initially 4-bit microprocessor 4004, then to 8-bit microprocessor 8008, then 8-bit microprocessor 8080, and later 16-bit microprocessor 8086.Starting from 8086, Intel entered the so-called x86 era.Intel 80

CPU usage depends primarily on what kind of resources are running on the CPU, such as copying a file that typically consumes less CPU, because most of the work is done by DMA (Direct Memory Access), but after the copy is complete, the CPU knows that the copy has been completed. Scientific computing usually takes up mor

CPU Footprint 100% Solution In general, CPU accounted for 100% of the words our computer will always slow down, and many times we can do a little bit of change can be solved, without asking those prawns. When the machine slows down, the first thing we think of is, of course, the task manager, to see exactly which program accounted for the ratio, if it is a large program that can be forgiven, in the shutdow

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

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
