网格环境下多集群资源虚拟化的设计与实现

Research and implementation of resource virtualization in multicluster under grid environment

针对网格基础平台与多集群的互操作问题,基于西北工业大学校园网格,提出集群资源调节器用以屏蔽集群调度系统的分布性,利用网格技术平台共享资源,消除信息孤岛,并结合调度系统管理作业,使得作业的吞吐量和资源的利用率达到最大化,实现资源虚拟化.通过实现自适应管理机制,准确刻画资源的动态性,提高系统的工作效率.

It is in favor of maximizing job throughput and utilization rate of resources to combine with cluster workload management(WLM) scheduling job based on grid sharing distributed resource in company.Currently,company or university has distributed cluster systems managed by various WLMs,so that it is more difficult to interactive operate between grid underlying platform and WLM.We design resource adjustor(RA) on Northwestern Polytechnical University Grid to mask distributed WLMs,eliminate 'Information Island' and implement resource virtualization.It can improve system efficiency by adaptive mechanism of RA which describes dynamic of resource accurately.
