摘　　要：POP、FVCOM、HYCOM为三种使用较为广泛的海洋数值模式,并且都具有可并行性,为了提高计算和执行效率,提出使用校园网格平台来实现。河海校园网格平台采用了WSRF、OGSA网格技术和三层结构,通过Portal、Shell和远程图形工具进行任务提交,并成功实现了POP、FVCOM、HYCOM模式的并行计算。实际应用表明,基于该平台的三种海洋数值模式计算时间缩短了6倍以上,并行效率超过了80%。To deal with the problem of calculation and execution efficiency, the parallel computing of ocean numerical model such as POP, FVCOM, HYCOM based on campus grid is designed in this paper. The platform of hohai campus grid adopts the grid technology such as WSRF, OGSA and three layer structures. The ways of job submission are Portal, Shell and remote graphical tools. The platform can accomplish the parallel computing of the three ocean numerical models. The experiment and application show that this platform can reduce the computing time of three models. The speedup is over 6x and parallel efficiency is over 80%
