| 摘 要： | 随着ＮＯＷ在科学研究中白益广泛的应用，如何为ＮＯＷ上的科学计算提供高性能的输入输出成为我们面临的一个新课题。作者根据ＮＯＷ的特点，设计并实现了一个具有ＮＯＷ特色的基于ＣｏｌｌｅｃｔｉｖｅＩ／Ｑ的并行Ｉ／Ｏ系统，吸取了ＤＤＩＯ与ｔｗｏ－ｐｈａｓｅＩ／Ｏ的优点，从而有效地解决了高带宽和低延迟问题。初步的系统吞吐量测试显示了良好的性能。

| Abstract: | As NOW is increasingly used to run scientific applications,how to provide high-performance I/O for I/O- intensive applications has become one of the crucial components in NOW environments. Collective I/O is a kind of effective organization Of I/O subsystem. In the paper we present the design and implementation of Collective I/O architecture on NOW.The initial performance evaluations have shown good I/O performance. |
