How to bind CPU to a process under Centos

This article focuses on "how to bind CPU to a process under Centos". Interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn how to bind CPU to a process under Centos.

Taskset is a CPU tuning tool that assigns system tasks to a specified CPU

This paper takes nodejs as an example.

First, query the nodejs process

Pgrep node

19277

19283

Step two, lock the CPU

Taskset-pc 0 19277 (where 0 represents CPU0, and so on)

Taskset-pc 1 19283

Step three, get it done!

Attach a small script that can automatically bind nodejs processes, assuming that four node,CPU are quad-core.

#! / usr/bin/env bash

Set-e

Node_porcess= `pgrep node | wc- l`

If [$node_process-eq0]; then

Echo "nodejs process not found"

Exit1

Else

Node1= `pgrep node | sort | tr-s "\ n" | awk' {print $1}'`

Node2= `pgrep node | sort | tr-s "\ n" | awk' {print $2}'`

Node3= `pgrep node | sort | tr-s "\ n" | awk' {print $3}'`

Node4= `pgrep node | sort | tr-s "\ n" | awk' {print $4}'`

Taskset-pc 0 $node1

Taskset-pc 1 $node2

Taskset-pc 2 $node3

Taskset-pc 3 $node4

Fi
