基于遗传算法的网格密码资源调度策略

Grid cipher resources scheduling strategy based on genetic algorithm

针对网格资源调度算法中不考虑服务请求实际需要的问题,按照用户对响应时间的实际需要,将服务请求划分成不同等级,以用户满意度为衡量指标,考虑系统的服务能力,兼顾系统负载平衡,利用遗传算法按需调度,更加高效合理地利用系统,使用户能够即时、高效、安全、灵活地获取资源。实验结果表明,该方法能够结合用户请求的实际需求,合理调度,更加充分利用系统资源,在性能上比传统算法有较大提高。

Aiming at the problem that the service request is not considered in the grid resource scheduling algorithm,the service request was divided into different levels according to the actual needs of the user＇s demands for response time,user＇s satisfaction was taken as a measure index,at the same time,considering the system＇s service capacity and the system load balance,genetic algorithm was used to schedule to make more efficient and reasonable use of resources,so that users can get the resources immediately,efficiently,safely and flexibly.Experimental results show that the proposed method can combine the actual needs of the user＇s request,reasonably schedule,and make full use of system resources.The performance of the algorithm is greatly improved.
