abstract: In the current PVFS2 design, load imbalances on the data servers could negatively affect the overall I/O performance. PVFS2 features a distribution interface, which can be used to implement various distribution functions. The distribution function concept is explained. A new Flexible Distribution Function is proposed, motivated by possible inhomogeneities in the hardware or access patterns. Flexibility depends on being able to redistribute data to match the access and load profile better. MPI-IO provides new data access semantics beyond the very limited capabilities of POSIX I/O. This interface is intended for use in parallel high performance applications. It is shown how it can be utilized to provide parallel redistribution for PVFS2. Additionally, some aspects of our development environment are mentioned and exemplified, including the usage of a decentralized version control system.
