Abstract

The present invention provides a cluster load balancing method transparent to an operation system. Main functional modules comprise a load balancing module, a processor migrating module and a communication module. The method is characterized by comprising the following steps: 1, driving a virtual processor to migrate; 2, driving balance migration; 3, sending a migrating request to a target node and negotiating; 4, storing and restoring a state of the virtual processor; and 5, communicating. The method better solves the problem of low resource utilization rate of a cluster system. Along with the development of more popularization of the cluster system and the continuous development of hardware virtualization technology in the future, the method can be a good solution for the low resource utilization rate of the cluster system and has good application prospect.

Description

(1) Technical field

[0001] The present invention mainly relates to a cluster load balancing method that is transparent to the operating system, specifically refers to computer hardware virtualization technology and single system image technology, through virtualization technology, computing tasks are reasonably allocated to different processors, thereby improving the cluster system. resource utilization. belongs to the computer field. (2) Background technology

[0002] 1. The load balancing technology of the current cluster system

[0003] A cluster system is a single computer system formed by interconnecting a group of independent computers through a high-speed communication network. Its advantages lie in its system resource availability, scalability and parallelism, so it has been widely used in the field of parallel processing.

[0004] As a server structure with good scalability and good performance, the cluster system has good cost performance. However, due to the lo...
