摘　　要：针对传统MPI集群并行I/O效率不高的问题,通过分析Lustre并行文件系统的特点和MPI-IO集中式I/O操作的算法,提出了一种基于MPI-IO编程接口的改进方案,用以改善集群I/O瓶颈,提高I/O并行效率,并通过实验验证了该方案的可行性。In accordance with the feature of traditional MPI cluster parallel I/O, an improvement of programming interface based on MPI-IO is proposed in this paper by studying the Lustre parallel file system and the operations algorithm of MPI-IO col- lective I/O in order to improve the cluster I/O bottlenecks and the efficency of parallel I/O. Finally, we demonstrate the effective- ness of this improvement through experiments.
