Abstract
One of the most severe performance limitations of parallel applications today stems from the performance of I/O operations. Numerous projects have shown, that parallel I/O in combination with parallel file systems can significantly improve the performance of I/O operations. However, as of today there is no support for parallel I/O operations for applications using shared-memory programming models such as OpenMP. This paper introduces parallel I/O interfaces for OpenMP. We discuss the rationale of our design decisions, present the interface specification and a prototype implementation with the OpenUH compiler. We evaluate the performance of our implementation for various benchmarks on different file systems and demonstrate the benefits of the new interfaces.
