Abstract
Vesta is an experimental parallel file system implemented on the IBM SP1. Its main features are support for parallel access from multiple application processes to a file, and the ability to partition and re-partition the file data among these processes. This paper reports on a set of experiments designed to evaluate Vesta's performance. This includes basic single-node performance, and performance using parallel access with different file partitioning schemes. Results are that bandwidth scales with the number of I/O nodes accessed, and that orthogonal partitioning schemes achieve essentially the same performance. In many cases performance equals the disk hardware limit. This is often attributed to prefetching and write-behind in the I/O nodes.
