CloudSim中基于偏序关系的调度算法研究

Study of Partial Order Based Scheduling algorithm in CloudSim

云计算是在海量数据的存取研究中比较热门的技术,任务调度则是云计算中的一个关键技术.在云仿真平台CloudSim中,任务调度算法忽略了任务本身的依赖关系和优先级.给CloudSim任务添加了相关的依赖关系和优先级,并提出了带偏序关系的任务调度算法POA.

Cloud computing is a popular technology in the study of handling massive data. Task scheduling is a key technology in the cloud computing. In cloud simulation platform CloudSim, task scheduling algorithm ignores the task dependencies and priority. In the paper, we added dependencies and precedence at- tributes to the task in CloudSim and proposed a task scheduling algorithm with partial order.
