Embodiment Construction

[0039] The core of the present invention is to provide a cluster-based load balancing method and its device. By combining the number of various loads running on each node, the balanced distribution of the load quantity can be realized, and the load usage on each node can be guaranteed as much as possible. Balanced distribution of resources.

[0040] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention. ...

Abstract

The invention discloses a load balancing method and device based on a cluster. The method comprises the following steps: recording the number of all kinds of loads running on each node in the cluster in real time; receiving a new load by the cluster; selecting a node having the minimum load number from unmarked nodes for marking, and if the cluster does not contain the unmarked nodes, selecting the node having the minimum load number to run the new load, and clearing the marks on all nodes; judging whether the currently selected node has the load the same as the type of the new load, if so, repeatedly selecting the node having the minimum load number from unmarked nodes to perform the subsequent operations; and if not, running the new load on the currently selected node, and clearing the marks on all nodes. According to the load balancing method and device disclosed by the invention, equilibrium assignment of the load numbers is realized in combination with the number of all kinds of loads running on each node, and the equilibrium assignment all resources used by the loads on the nodes can be ensured as much as possible.

Description

technical field [0001] The invention relates to the technical field of cluster resource allocation, in particular to a cluster-based load balancing method and device thereof. Background technique [0002] In the field of computer clusters, many different types of workloads run on the cluster. In order to stabilize the cluster and improve the service life of the cluster nodes, some rules are needed to distribute the load. [0003] Most of the methods currently used are to distribute the load by calculating the cpu usage rate of the nodes or the network bandwidth usage rate. In this distribution method, if there is a load with a particularly high CPU usage or network bandwidth usage, some cluster nodes will have a small number of loads, while some nodes will have a large number of loads, and the load distribution will not be enough. balanced. [0004] Therefore, how to provide a cluster-based load balancing method and device with good balancing performance is a problem that...
