Embodiment Construction

[0022] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0023] figure 1 It is a schematic diagram of an implementation environment shown according to an exemplary embodiment. In this implementation environment, when the remaining resources of the computing devices are available for distribution, the distribution device 101 screens out tasks that need to be distributed currently, and distributes the screened tasks to each computing device 102 for parallel execution. Assuming that there are N task encapsulation objects in the task queue of the distribution device 101, the calculation of the allocation weight is performed for each task encapsulation object, wherein each task encapsulation object can be divided into sev...

Abstract

The invention discloses a task scheduling method and apparatus. The method comprises the steps of calculating an allocation weight of each task according to the position, waiting duration and priority of each task in a task queue; and screening out a task required to be allocated currently according to the allocation weight of each task in the task queue. The task allocation is influenced by the priority as well as the position and waiting duration of the task in the queue, so that the situation that the task with the low priority has to be executed after the task with the high priority is processed can be prevented, long-term waiting of the task with the low priority is avoided, and the congestion of the task with the low priority is prevented from being formed.

Description

technical field [0001] The present invention relates to the field of computer applications, in particular to a task scheduling method and device. Background technique [0002] At present, when using a computer for business processing, the tasks to be processed are usually divided into different priorities according to the type of business, and the tasks are sorted in the task queue according to the order of priority, so that the tasks with higher priority are executed first. [0003] However, since the low-priority tasks must wait until the processing of the high-priority tasks is completed, the low-priority tasks are blocked for a long time. Contents of the invention [0004] The purpose of the present invention is to provide a method and device for task scheduling to avoid blocking of low priority tasks. [0005] In one aspect of the embodiments of the present invention, a task scheduling method is provided. For example, the method may include: calculating the distribu...
