Experimental performance analysis is a necessary first step in input/output software tuning and real-time environment code performance prediction. We measure the performance and scalability of IBM's General Parallel File System (GPFS) under a variety of conditions. The measurements are based on a set of benchmark codes that allow us to vary block sizes, access patterns, etc., and to measure aggregate throughput rates. We use the data to give performance recommendations for application development and as a guide to the improvement of parallel file systems.
