Resource scheduling method and resource scheduling system

Abstract

An embodiment of the invention provides a resource scheduling method and a resource scheduling system and relates to the field of cloud calculation. The resource scheduling system comprises a management node and physical nodes. According to the resource scheduling method, by the aid of the management node, a resource set corresponding to each application program is acquired according to the scheduling policy of a user when an objection of a scheduling policy is achieved and then is sent to the each physical node; by the aid of each physical node, the minimum quantity of resources distributed to each virtual machine on the corresponding physical node are determined, the left quantity of resources are distributed to every virtual machine on the corresponding physical node proportionally, and the total quantity of resources obtained by each virtual machine after distribution are sent to the management node; by the aid of the management node, resource utilization rate of each physical node is acquired according to the corresponding total quantity of resources of each virtual machine and the current resource utilization amount of each virtual machine on the corresponding physical node, and resource load of each physical node is scheduled according to the resource utilization rate. The resource scheduling method and the resource scheduling system are applied to virtualized resource scheduling and can solve the problem of unreasonable resource distribution caused by an incompatible scheduling technology.

Description

technical field [0001] The invention relates to the field of cloud computing, in particular to a resource scheduling method and a resource scheduling system. Background technique [0002] The scheduling of infrastructure resources in the data center can be divided into three levels, including: resource scheduling at the application layer, resource scheduling at the virtual machine layer, and resource scheduling at the physical machine layer. [0003] Among them, the first-in-first-out queue (First Input First Output, FIFO), fair scheduling algorithm, and computer capacity scheduling algorithm implemented in the software architecture MapReduce for large-scale data set parallel computing belong to the application layer resource scheduling algorithm, and its goal is to maximize Optimize the task throughput of the application layer or minimize the task completion time; the scheduling algorithm of the virtual machine layer can represent the credit scheduler algorithm in the Xen s...
