| Abstract: | 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 collective I/O in order to improve the cluster I/O bottlenecks and the efficency of parallel I/O.Finally,we demonstrate the effectiveness of this improvement through experiments. |
