The design and implementation of PVFS are described and performance results on the Chiba City cluster at Argonne are presented, both for a concurrent read/write workload and for the BTIO benchmark.
The release of OrangeFS aims to add production quality features to the open source, community driven code base of PVFS, which aims to support large scale file systems and make parallel file systems available in more traditional computing environments.

The implementation of IEEE single precision floating-point multiplication and addition is discussed, followed by a discussion of an algorithm, matrix multiplication, based on these operations, which achieves performance comparable to conventional microprocessors.
A bandwidth-centric job communication model that captures the interaction and impact of simultaneously co-allocating jobs across multiple clusters is presented and the performance of multi-cluster scheduling algorithms that focus not only on node resource allocation, but also on shared inter-clusters network bandwidth is evaluated.

The Parallel Virtual File System (PVFS) is presented, a system that provides disk striping across multiple nodes in a distributed parallel computer and file partitioning among tasks in a parallel program and which achieves excellent speedups in accessing moderately sized file segments.

This work is currently undertaking a major rewrite of PVFS to include several new features and a new internal architecture to create a new file system for Beowulf class parallel computers.
A bandwidth-centric parallel job communication model is made use that captures the time-varying utilization of shared inter-cluster network resources and is able to evaluate the performance of grid scheduling algorithms that focus not only on node resource allocation, but also on shared Inter-Cluster network bandwidth.
A scalable distributed directory for Orange File System is implemented and evaluated in a largescale system and shows great scalability in concurrently creating and removing large numbers of files under one directory by multiple clients.
This dissertation demonstrates how client-side file data caching can improve parallel file system throughput for applications performing frequent small and unaligned file I/O and shows that high-level file system interfaces can significantly accelerate application performance, and interfaces beyond those currently envisioned by the MPI-IO standard could provide further performance benefits.
