摘　　要：提出了一个基于数据通路的波浪推进式并行I/O模型框架,并在基于Linux的SMP机群系统中,根据波浪推进式并行I/O模型框架对各个数据通路进行建模,具体分析了这个波浪推进式并行I/O模型,从思路上解决了刻画并行I/O性能的并行I/O模型问题。A new parallel I/O framework mo de l based on wave-pushing type of data channel is proposed.On the basis of the p arallel I/O model framework based on wave-pushing type,the models of each da ta channel are built under the system architecture of SMP cluster based-linux .At last,the parallel I/O model of wave-pushing type is analyzed con-cret ely.The research work resolves the problem of model that depicts the parallel I/O performance from methods.
