Abstract

The invention relates to a cloud computing task scheduling method based on tabu search and load balancing. According to the method, a task scheduling initial solution is obtained on the basis of a heuristic priority allocation strategy of the earliest finish time; then, candidate exchange task pairs are generated on the basis of using the tabu search as an instructional neighborhood search optimization strategy, the task pairs with great profit values are exchanged by adopting a greedy principle, and the task scheduling initial solution is optimized, so the completion time span of the whole task is shortened to the greatest degree. After the cloud computing task scheduling method based on tabu search and load balancing is adopted, the task scheduling efficiency is effectively improved, the load balancing of a cloud computing platform is realized, the idle time of resources is also obviously reduced, the utilization benefits of the resources are improved, and better practicability is realized.

Description

technical field [0001] The invention relates to a cloud computing task scheduling method based on tabu search and load balancing in a cloud computing environment. Background technique [0002] As the product of the integration and development of traditional technologies such as distributed computing, parallel computing, and grid computing, and new technologies such as network programming models, distributed data storage technology, and virtualization technology, cloud computing is a key strategic technology and means leading innovation in the information industry , has important strategic significance for the development of high-tech industries in my country. Cloud computing divides computing tasks on large-scale cheap server clusters, so that people can use idle resources distributed in various places to process more complex applications, and obtain extremely high computing quality at a very low cost. [0003] The essence of task scheduling in the cloud computing environmen...
