Little Chenbo main 2017-11-30 21:11:56 preface to the Broken language In the stand-alone application period, the task scheduling is generally based on spring schedule and integrated quartz to achieve, when the system developed into distributed services, the application of multiple instances, the task will appear many times the problem, many times our task does not need to run many times. There are many solutions, the simplest and most brutal of which

Scheduling algorithm refers to the resource allocation algorithm according to the system resource allocation strategy, such as task A after execution, select which task to execute, so that a factor (such as process total execution time, or disk seek time, etc.) minimum. For different system targets, different scheduling algorithms are usually used.Several common operating system process

Design and Implementation of Linux kernel Reading Notes (4)-Main content of process scheduling: What is scheduling implementation principle system call related to method scheduling implemented by scheduling on Linux 1. what is scheduling the current operating system is multi

Ten LVS cluster scheduling algorithms and load balancing theory, lvs Load Balancing I. Concept of LVS LVS (Linux Virtual Server): Linux Virtual Server; LVS is a server Load balancer device that does not provide any services. When a user requests a Server Load balancer, LVS forwards the customer's requirements to the backend to provide services, therefore, backend services are called real servers; LVS is divided into two sections. The previous sec

One, the task of process scheduling(1) Save the site information of the processor. In the scheduling of the first to save the current processor's field information.(2) Select the process according to an algorithm. The scheduler chooses the process according to an algorithm, changes its state to a running state, and prepares to assign the processor to it.(3) Assign the processor to the process. The dispatche

The process scheduling algorithms in Linux are categorized as follows:First, first come service and short job ( process ) priority scheduling algorithm1. First come first service scheduling algorithm (FCFS) first come first serve FCFS) scheduling algorithm is one of the simplest , non-preemptive

A DescriptionTaking linux-2.4.10 as an example, this paper mainly analyzes the schedule function and its related functions in Linux process scheduling module. In addition, the relevant prerequisite knowledge will also be explained. The default system platform is the PC of its own i386 architecture.Two Prerequisite knowledgeBefore schedule analysis, it is necessary to briefly explain the system boot process, memory allocation and so on. This will natur

As we all know, the latest Linux kernel uses the scheduling mechanism of CFs. Many articles on the Internet have made a detailed analysis of the source code of CFS scheduling. However, most articles focus too much on details, therefore, we did not summarize the concept of CFS as a whole. For this reason, this article describes the basic principles of CFS scheduling
