云计算环境下多级映射作业调度算法的研究

云计算是一种新兴的资源使用和计算交互模式,是目前商业机构和科研机构的研究热点之一.在云计算环境中用户需求和资源的分布对该环境中作业调度的影响很大,虚拟技术的使用使云计算环境中的作业调度与传统的作业调度存在很大的差别.针对云计算环境特点,根据用户的需求将作业进行分类,同时将资源分类,引入中间代理节点进行任务调度,形成多级映射作业调度算法,提高作业的并发度,使总任务完成时间缩短.通过实验验证多级映射作业调度算法是一种可行的作业调度算法.

Research on multi-level tasks scheduling in cloud computing environment

Cloud computing is an emerging model of resource usage and business computing. It＇ s one of the research highlights of business organizations and research institutions. User demands and distribution of resources have great influence on the job scheduling in a cloud environment. The use of virtual technology makes the job scheduling in the cloud computing environment and the traditional job scheduling have a big difference. The assignment and the resources will be classified according to the user demand and the characteristics of the cloud computing environment. Through introducing the intermediate proxy node to finish task scheduling, a multistage mapping scheduling algorithm was proposed. The experiment proves that the algorithm which can shorten the total task completion time and improve the assignment concurrency is an available job scheduling algorithm.
