Cloudsim中基于智能算法的任务调度研究

摘要

Cloud computing is a kind of large distributed computing model based on Internet and obtains service resource as required. Task scheduling is one of the key techniques of cloud computing. The task scheduling directly affects the execution efficiency of the task submitted by users and their satisfactory degree on the service. Based on this, this paper compares the performances of several task scheduling algorithms, and integrates optimal scheduling idea into the basic algorithm. Practice shows that the algorithm designed in this paper has saved time for task scheduling, so it has certain feasibility.%云计算[1]是一种基于网络的、按需获取服务资源的大型分布式计算模式。任务调度则是云计算中的关键技术之一，任务调度策略的优劣直接影响到用户提交作业的执行效率和对服务质量的满意度。针对于此，本文将几类传统任务调度算法的性能进行了比较，并在基本算法的基础上融入最优调度的思想，实验证明本文所设计的算法在一定程度上节约了任务的总调度时间，有一定的可行性。
