Parallel access to files in the Vesta file system

Abstract

The Vesta parallel file system is intended to solve the I/O problems of massively parallel multicomputers executing numerically intensive scientific applications. It provides parallel access from the applications to files distributed across multiple storage nodes in the multicomputer, thereby exposing an opportunity for high-bandwidth data transfer across the multicomputer's low latency network. The Vesta interface provides a user-defined parallel view of file data, which gives users some control over the layout of data.
