cpu miner

Problem:Run the vmstat, top, and PS aux commands to view the CPU usage of the process. The value varies greatly. Example:Use vmstat to view the system's CPU idle rate. The ID is the CPU idle rate. It can be seen that the idle rate is always above 73%.Use PS aux to count the CPU usage of two compress processes. The

CPU scheduling for multi-channel programs The following discusses the scheduling problem for a single CPU. Review the multi-channel program while importing multiple processes into memory so that a process is used to fill the CPU's time when it performs I/O in the CPU. Typically processes are converted between the CPU i

Metrics to measure CPU performance:1, the user uses the CPU situation;CPU runs regular user processesCPU Running niced ProcessCPU running real-time process2, the system uses CPU condition;For I/O Management: interrupts and drivesFor memory management: page swappingUser Process Management: Process start and context swit

Http://ilinuxkernel.com/?cat=4Linux CPU Utilization principle and accuracy analysis1 CPU Usage Calculation principleUnder Linux/unix, CPU utilization is divided into user state, System State and idle state, which indicate the time that the CPU is in user state execution, the time the system kernel executes, and the tim

The modern CPU and motherboard have power-saving technologies, which automatically reduce the frequency when the CPU is low-load. If you need to temporarily set the clock speed and working mode, you can use cpufreq to manually adjust it. This mode will expire after restart. if you need to adjust it for a long time, modify/etc/sysconfig/cpuspeed. 1. check whether the kernel has been loaded by running the lsm

Hardware monitoring refers to monitoring the physical health of a computer, including monitoring such as CPU utilization, memory availability, disk space remaining, and so on.In this section, we'll set up CPU-related hardware monitoring for a SharePoint farmSharePoint monitoring ②: CPU load monitoring for hardware monitoringAlert Thresholds: Serve

CPU subsystem The most common parameter of the CPU subsystem is CPU. Shares. We can trace the read and write operations on this parameter through the cgroup Learning (3)-pseudo file table.Through systemtap, we can see the read BT :( cat CPU. shares) 2327 (cat) cpu_shares_read_u64 call trace: 0xffffffff8104d0a0 : cpu_sh

Reprinted from: http://blog.csdn.net/pppjob/article/details/4060336Under Linux, CPU utilization is divided into user state, System State and idle state, respectively, the CPU is in user state execution time, system kernel execution time, and idle system process execution time, the sum of which is the total CPU time, when there is no user process, system process,

When CPU usage is frequent 100%, the main problem can occur in some of the following areas: Nine possibilities for high CPU usage 1, anti-virus software caused the failure Because of the new version of KV, Jinshan, rising are added to the Web page, plug-ins, mail random monitoring, undoubtedly increased the system burden. Treatment: Basically there is no reasonable treatment, try to use the least monitor

Not long ago, under the friend's egged, I also DIY computer. Although the spirit of "practical, adequate." "Principle, but a few sets of plans to save machine in my mind around, make me indecisive. Hey! What about it--take money to the computer city for a spin.Saturday, I went to the computer city two laps, finally set a "package": CPU with CELERON433, Pan English motherboard (3VBA), Phillip Display (105G), 8.4G hard disk, xiaoying pa tnt16m graphics

The method of adjusting affinity This section describes how to improve process-to-CPU affinity, CPU and memory affinity, and the affinity of virtual CPUs to physical CPUs. 1. Binding process For dedicated CPU mode, the binding process can be applied to the specified CPU. 2. Adjust
