Abstract

The invention discloses a task scheduling method and device. According to the specific implementation mode of the task scheduling method, following scheduling processing operation is periodically triggered according to the scheduling period. The scheduling processing operation includes the steps that scheduling time of current scheduling processing operation is obtained; time parameters of each task to be scheduled are obtained, wherein the time parameters comprise the recent use starting time of the tasks to be scheduled and the task executing period, and the task executing period is the interval between two adjacent execution starting time of the tasks to be scheduled; the task executing period, the recent use starting time and the tasks, meeting the preset condition, to be scheduled are output to a task pool; the tasks in the task pool are distributed and executed. By means of the implementation mode, the task scheduling efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of computers, in particular to the technical field of task scheduling processing, and in particular to a method and device for task scheduling. Background technique [0002] Task scheduling is an important part of the operating system. For the unified scheduling of periodic tasks, in the prior art, the scheduled task is mainly determined by judging that the time difference between the current time and the last execution start time of the task is greater than the task execution interval. In some implementations, in order to avoid the task being executed again Scheduling also needs to lock the task when the task is scheduled, and unlock the task when the current execution of the task is completed. In this method of task scheduling, two data write operations of locking and unlocking are added during the process of each task being scheduled once. When the number of tasks to be scheduled is large, ther...
