A priority-based resource allocation method, device and equipment

Abstract

The present application provides a priority-based resource allocation method, including: accepting a resource application submitted by a job, the resource application including resource requirement information and job priority information; judging the remaining resources of the system according to the resource requirement information of the resource application Whether the resource application is satisfied, when the remaining resources do not satisfy the resource application, sequentially traverse the allocated resource applications whose job priority is lower than the resource application in the allocated resource application queue; traverse all The sum of the system resources occupied by the received resource applications and the remaining resources are added as available resources; when the available resources satisfy the resource application, stop traversal, and allocate the available resources to the resource application. The technical solution of the present application solves the problem that a resource application with a high job priority can preempt a resource application with a low job priority. The present application also provides a priority-based resource allocation device and equipment.

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...
