linux set process priority

Why do you have a process priority?This does not seem to explain too much, after all, since the birth of a multitasking operating system, the ability of the process to execute CPU is a matter that must be artificially controlled. Because some

First, prefaceThis article mainly describes the concept of process prioritization. From the user space, the process priority is nice value and scheduling priorities, corresponding to the kernel, there are static priorities, realtime priority,

Three scheduling strategies for the Linux kernel:1,sched_other time-sharing scheduling strategy,2,sched_fifo Real-time scheduling strategy, first-come-first service. Runs continuously once the CPU is occupied. Keep running until a higher priority

Process priorityProcess CPU resource allocation refers to the priority of the process. High priority processes have priority rights to implementation.Permissions and precedence. Permissions (privilege) refers to the management of a multiuser

Linux Process Priority and nice value, linux priority nice After learning the complete Fair Scheduling Algorithm (CFS) of linux, record the learning track This article mainly describes how the scheduling algorithm works and some scheduling knowledge.

The target of Linux process scheduling1. Efficiency: High efficiency means that more tasks are done at the same time. The scheduler will be executed frequently, so the scheduler should be as efficient as possible;2. Enhance the interactive

Linux Process Scheduling analysis and linux scheduling AnalysisOverview Multi-process scheduling is essential for the operating system. Some people say that process scheduling is the most important part of the operating system. I think this is an
