Priority-based resource allocation method, apparatus and device

Abstract

The invention provides a priority-based resource allocation method. The method comprises the steps of receiving a resource application submitted by a job, wherein the resource application comprises resource demand information and job priority information; according to the resource demand information of the resource application, judging whether residual resources of a system meet the resource application or not, and when the residual resources do not meet the resource application, sequentially traversing allocated resource applications with job priorities lower than the job priority of the resource application in an allocated resource application queue; taking system resources occupied by all the traversed resource applications and the residual resources as available resources; and when the available resources meet the resource application, stopping traversing, and allocating the available resources to the resource application. According to the technical scheme, the problem that the resource application with a high job priority can be prior to the resource application with a low job priority is solved. Meanwhile, the invention furthermore provides a priority-based resource allocation apparatus and device.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to a priority-based resource allocation method. Corresponding to the above method, the present application also relates to a priority-based resource allocation device and equipment. Background technique [0002] In a distributed system, there are usually three roles: resource scheduler, job manager and subordinate job nodes, and machine nodes. When a user needs to submit a job, the job manager will apply to the resource scheduler for a certain amount of machine resources, such as CPU and memory, for use by the job nodes; Calculate the list of available resources that can be assigned to the job manager by calculating the remaining available resources in . The list of resources is sent to the job manager and corresponding machine nodes. [0003] In a distributed system, there are tens of thousands of job managers. Usually, the job priorities of the resource applicati...
