1. DescriptionThis document is for the summary of self-study, data sources see information, and some from the network and the author's understanding, cannot guarantee 100% correct.The purpose of this paper is to explain the task scheduling scheme of Linux operating system, and to form a separate chapter about the scheduling of Windows. The main purpose is to give the general public a basic understanding of

Transfer from http://www.ibm.com/developerworks/cn/linux/l-completely-fair-scheduler/index.html?ca=drs-cn-0125A brief history of Linux Scheduler the early Linux Scheduler used the lowest design, and it obviously did not focus on large architectures with many processors, Not to mention Hyper-threading. The 1.2 Linux Scheduler uses circular queues for operational task management, using a cyclic scheduling strategy. This scheduler adds and removes proce

Fourth Chapter Process SchedulingThe process scheduler can be seen as a kernel subsystem that allocates a limited amount of processor time resources between running too processes. The scheduler is the basis for multitasking operating systems. Through the reasonable scheduling of the scheduler, the system resources can play a maximum role, the multi-process will have the effect of concurrent execution.The principle of maximizing processor time is that

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 interval and the I/O interval. The CPU scheduler is called a short-term scheduler, from mem

Traditional elevator SchedulingAlgorithm 1.1 Service algorithms first(FCFS) Service first(FCFS-first come first serve)The algorithm is a kind of instant service algorithm. It is not only not optimized for finding floors, but also has no real-time features. It is the simplest elevator scheduling algorithm. It is scheduled according to the order in which passenger

1 IntroductionMultimedia frameworks are very important and important modules. Especially in Android systems, it is necessary to understand the multimedia playing effect.The scheduling problem in multimedia is a story behind it, but it has a crucial impact on the performance. This article does not fully analyze the Multimedia Framework and aims to explore the differences between the scheduling of media frame

Starting from this blog, we will go deep into process management and even the core concept of the entire kernel-process scheduling. Here, let's take a look at the relevant concepts. We have just started to talk about Linux. It is a time-sharing system, but it has the characteristics of a real-time system. So like any time-sharing system, a quick switch from one process to another achieves the magical effect of simultaneous execution of multiple proce

I. kernel Overview:In a multi-task system, the kernel is responsible for managing tasks, or allocating CPU time for each task, and communicating between tasks. The basic service provided by the kernel is task switching. The use of the Real-Time Kernel greatly simplifies the design of the application system because the real-time kernel allows applications to be divided into several tasks and managed by the real-time kernel. The kernel itself also increases the application load, the code space inc
