The CPU vulnerability is finally eliminated! AMD: BIOS updates for Ryzen and EPYC platforms are released this week. ryzenepyc Previously, amd cto (Chief Technology Officer) Mark Papermaster updated the AMD processor Security description (Chinese pages are not yet online ). Specifically, for V1 in the Spectre Vulnerability (bypassing the boundary check), AMD still believes that it can be solved by updating the operating system and software. Micr

HadoopYARN supports both memory and CPU scheduling (by default, only memory is supported. If you want to further schedule the CPU, You need to configure it yourself ), this article describes how YARN schedules and isolates these resources. In YARN, resource management is completed by ResourceManager and NodeManager. Hadoop YARN supports both memory and CPU schedu

Mature computer users, in addition to being careful when buying computer hardware, know how to maintain your computer is also very important. Because the computer is well maintained, it can not only help you complete your work smoothly, but also serve you "Faithfully" for a long time. Today, let's take a look at the computer's brain-how to maintain the CPU to stay young! The CPU (central processor) is like

These days I have been studying shell scripts and writing some system load and CPU monitoring script programs. Without nagios monitoring software, as long as the server can access the Internet, you can send an email to remind the administrator of the system load and CPU usage. I. install the shell script and write some system load and CPU monitoring script progra

four pieces of data from/proc/STAT: user mode, nice mode, and system mode) and idle processor time (idle ). They are located in the first line of the/proc/STAT file. The CPU usage is calculated using the following formula.CPU usage = 100 * (User + nice + System)/(User + nice + system + idle)(2) memory usageHere we need to extract two data from the/proc/meminfo file, the current memory usage (cmem) and the total memory (amem ).Memory usage percentage

subsystems are mounted by default.Cgroup Subsystem IntroductionOf course, the user can customize the subsystem and mount it.The following is a brief introduction to each subsystem: The Blkio setting restricts the input and output control of each block device. For example: disks, CDs, USB, and so on. The CPU uses the scheduler to provide CPU access to the Cgroup task. CPUACCT generates

Personally, performance optimization is intended to improve application or system capabilities. So how can you achieve tuning your application performance?

Solving the performance problems of a database system can be a daunting task. It is important to know how to find the problem, but it is more important to understand why the system responds specifically to specific requests. Affect CPU utilization on the database server There are many factors: compiling and recompiling SQL statements, missing indexes, multithreaded operations, disk bottlenecks, memory bottlenecks, routine maintenance, and extraction,

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

Many people in the process of using a notebook, often pay attention to their CPU performance, we will see the notebook CPU model behind the usual "U", "M" and other words, and "u" is the meaning of low pressure, "M" is the meaning of the standard pressure.
