| 摘 要： | GridSim模拟器是网格相关研究中通用的模拟、分析工具.为了进一步丰富GridSim模拟器功能以使其更好地支持算法、性能模拟,提出并实现了在GridSim中引入优先级的预留策略,扩充了GridSim的性能.在优先级预留系统中,对GridSim预留模块中已有的先来先服务（FCFS）预留调度算法进行了改进,将优先级与先来先服务相结合提出了一个新的预留调度算法ARWithPriorityPolicy.实验结果表明,结合优先级的预留调度算法可以有效减少被拒绝的预留请求数目.

| Abstract: | GridSim simulator is a general simulation and analysis tool for Grid related research.In order to further enrich its simulation functions to better support algorithms and performance simulation,a reservation strategy that priority should be introduced in GridSim is proposed and implemented.In the priorty -based reservation system,the existing first-come-first-serve(FCFS) scheduling algorithm in the reservation model of GridSim is enhanced,and a new reservation-based scheduling algorithm-ARWithPriorityPolicy,which combines priority with FCFS,is put forward.The simulation results show that this reservation-based scheduling algorithm with priority can decrease the amount of reservation requests rejected effectively. |
