摘要： 在大规模并行处理系统ＭＰＰ商业化应用中，并行文件系统容量与Ｉ／Ｏ节点的负载平衡一直是挖掘整个系统并行性，进而提高系统性能的关键问题之一．本文从分析Ｐａｒａｇｏｎ大规模并行处理系统的体系结构和并行文件系统的体系结构出发，给出了并行文件系统的扩容策略，使用ＭＰＰ系统的Ｉ／Ｏ节点平衡负载理论模型，给出了实际工程应用中的负载平衡策略．

Abstract: The capacity of parallel file system(CFS) and I/O load balancing is one of the key problems of improving system performance in the application of Paragon massive parallel processing system and parallel file system. this paper presents the enlarging methods for file system capacity. Using the theoretic model of MPP I/O node balancing. we propose the load balancing strategies in the engineering application.
