Problems solved by technology

[0003] Most of the current existing technologies only involve the timing of resource preemption and the resources that can be preempted, but how to perform reasonable resource preemption in terms of the impact on system performance is rarely involved, and there is no good solution

Abstract

The invention provides a method, device and apparatus for preempting resources and a computer storage medium, wherein the method comprises the following steps: after the task needs to be preempted, according to the preemptable resources of at least a part of nodes in a node cluster, determining a node set whose preemptable resources satisfy the resource occupancy amount of the task to be allocated; preselecting a backup preemption task set of each node in the node set; determining the preemption cost of each node in the node set respectively according to the backup preemption task set of eachnode; according to the preemption cost, selecting a node in the node set for resource preemption of the task. The resource preemption method can not only guarantee the resource preemption, but also preempt the resource according to the preemption cost, which can reduce the waste of the resource and the impact on the system performance as much as possible.

Description

【Technical field】 [0001] The present invention relates to the field of computer application technology, in particular to a resource preemption method, device, equipment and computer storage medium. 【Background technique】 [0002] In recent years, the live video industry has developed rapidly, and with the improvement of panoramic video technology, an important requirement in the video transcoding system is to be able to support live broadcast and on-demand panoramic video at the same time. Compared with on-demand tasks, live broadcast tasks are often more urgent and important, so they need to be executed first. If there are not enough resources at this time, it will involve the problem of resource preemption, such as interrupting some on-demand tasks to release some resources for live broadcast. In addition to panoramic video transcoding, other application scenarios also involve task priority issues. In order to ensure that high-priority tasks can be executed first, it is n...
