Many parallel file systems present applications with a conventional Unix-like interface that allows the application to access multiple disks transparently. By tracing all the activity of a parallel file system in a production, scientific computing environment, we show that many applications exhibit highly regular, but non-consecutive I/O access patterns. Since the conventional interface does not provide an efficient method of describing these patterns, we present three extensions to the interface that support \emph{strided}, \emph{nested-strided}, and \emph{nested-batched} I/O requests. We show how these extensions can be used to express common access patterns.}, }
