I) Summary of the I/O Scheduler
1) when a data block is written to or read from the device, the request is placed in a queue waiting for completion.2) each block device has its own queue.3) the I/O scheduler is responsible for maintaining the order of these queues to make more effective use of media. the I/O scheduler converts unordered I/O operations into ordered I/O operations.4) The kernel must first determine the total number of requests in the queue before
Linux schedules many processes. This involves the concept of Linux Process Scheduling timing, which is determined by the Schedule function in the Linux kernel, if you want to switch, which process to switch to, and so on.
Linux Process Scheduling time mainly includes::
1. process state transition time: Process Termination and process sleep;
2. When the time slice of the current process is used up, current->

The 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 as long as there are processes th

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

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
