Abstract: This paper examines the feasibility of InfiniBand technology to design and implement an Effective Parallel File System(EPFS). It designs a transport layer customized for EPFS by trading transparency and generality for performance, buffer management for flow control, dynamic and fair buffer sharing, and efficient memory registration and deregistration. Compared with an EPFS implementation over TCP/IP on the InfiniBand network, the implementation offers better I/O performance if the number of I/O nodes is not bottleneck. Further, two-level memory registration and deregistration technology(AFMRD) works much better than pin-down cache technology.

摘要： 利用InfiniBand技术特征实现高效的并行文件系统(EPFS)，设计一个高性能的透明传输层，对数据流的缓存管理、动态和公平的缓存共享，以及有效的内存注册和注销进行研究。实验表明，当I/O节点足够多时，随着计算节点的增加，基于InfiniBand 技术的EPFS比基于TCP/IP的EPFS的读写性能增长更快。并且，两级别的内存注册和注销方法AFMRD比受约束的缓存技术更好地改进I/O性能。
