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.
