| 摘 要： | 网格是一种复杂的分布式计算系统，研究其网格服务对网格作业的调度算法的分布式部署和性能分析问题具有重要的意义。网格服务调度系统的状态空间模型考虑了具有不同的输入速率和输出速率的作业队列，提出了清空型调度策略和服务调度算法，并在此基础上分析了其分布式部署问题，计算了系统QoS性能指标，指出了稳态吞吐量、稳态响应时间与负载系数的关系。

| Abstract: | Grid is a complex distributed computing system, distributed deployment and QoS performance analysis of grid services scheduling algorithm were studied. State space model was given to describe the grid dynamic scheduling system which processes a number of heterogeneous jobs concurrently. Clearing policy as a scheduling poficy and services sched uling algorithm were given. Distributed deployment problem was analyzed. System QoS performance parameters were calculated, stable throughput and stable response time and their relationship with load factor were pointed. |
