Analysis of POSIX I/O extensions


EMSL Project ID
28292

Abstract

The POSIX I/O API presents challenges with respect to achieving high performance on parallel file systems. We have proposed several extensions to the POSIX API, prototyped them in the PVFS file system and Linux-2.6.16 kernel, and benchmarked their improvements at small scale. The MPP2 cluster, however, represents a chance for us to quantify our improvements at larger scale.
