Tags: task SSI set range to and star Refresh Art referenceThe scheduler accomplishes the following tasks: Clock interrupt (or similar timer) time slice of refresh process, set process dispatch flag Check dispatch flags when system call returns or interrupts complete Schedule functionThe function that completes the process dispatch in the kernel code is schedule (), which contains the following calls: Put_prev_task (RQ, prev); Next = Pick_next_task (RQ); Context

The operating system development processManual operation mode: artificial input and output, the user exclusive whole machine. Offline input/Output mode: High-speed tape is i

has been busy with the development of an application in the lab, which is to write a real-time system scheduling algorithm analysis and simulation in Java. Of course, this process inevitably collects the data of the real-time system scheduling algorithm, as well as the realization of various real-time system algorithms and the application scope of the scheduling

I. Differences in process and operationsDifference: A process is a single execution of a program on a data set, and a job is a task that the user submits to the system.Relationship: A job usually consists of several processes, and several processes work together to complete a task, that is, a job.Job scheduling is a macro-scheduling, which determines which job can enter main memory. Process

From the 1th edition of Linux in 1991 to the later 2.4 kernel series, the Linux scheduler is fairly rudimentary, and the design is almost primitive, see version 0.11 kernel process scheduling . It's easy to understand, of course, but it's hard to handle in many running processes or multiprocessor environments.Because of this, in the Linux2.5 development series of the kernel, the dispatcher did a major operation. A new scheduler called the O (1) schedu

Task scheduling is a useful system management tool in both Linux and Windows operating systems. For example, you can schedule the task so that the operating system can automatically monitor the hard disk Task scheduling is a useful system management tool in both Linux and Windows operating systems. For example, you can schedule the task so that the operating system can automatically monitor the disk usage.

Three process scheduling methods for Linux kernel in the operating system1. SCHED_OTHER time-based scheduling policy;2. SCHED_FIFO real-time scheduling policy, first served first;3. SCHED_RR real-time scheduling policy, time slice rotation.Real-time processes will receive priority calls. Real-time processes determine t

Disk scheduling algorithm Disk scheduling in a multi-channel program-designed computer system, each process may constantly present different requests for read/write operations on the disk. Because sometimes these processes send requests faster than disk response, it is necessary for each disk device to establish a waiting queue, the common disk scheduling
