%T A Split-Phase Interface for Parallel File Systems %A Sanjay Khanna %A David Kotz %R Technical Report PCS-TR97-312 %I Dartmouth College, Computer Science %C Hanover, NH %D March 1997 %U http://www.cs.dartmouth.edu/reports/TR97-312.ps.Z %X We describe the effects of a new user-level library for the Galley Parallel File System. This library allows some pre-existing sequential programs to make use of the Galley Parallel File System with minimal modification. It permits programs to efficiently use the parallel file system because the user-level library groups accesses together. We examine the performance of our library, and we show how code needs to be modified to use the library.
