Abstract

In the past couple of years, significant progress has been made in the development of message-passing libraries for parallel and distributed computing, and in the area of high-speed networking. These advances in computing technology have also led to a tremendous increase in the amount of data being manipulated and produced by scientific and commercial application programs. Despite their popularity, message-passing libraries only provide part of the support necessary for most high performance distributed computing applications -- support for high speed parallel I/O is still lacking. In this paper, we provide an overview of the conceptual design of a parallel and distributed I/O file system, the Virtual Parallel File System (VIP-FS), and describe its implementation. VIP-FS makes use of message-passing libraries to provide a parallel and distributed file system which can execute over multiprocessor machines or heterogeneous network environments.
