| Abstract | Because both processor and interprocessor communication hardware is evolving rapidly with only moderate improvements to le system performance in parallel systems, it is becoming increasingly diicult to provide suucient input/output (I/O) performance to parallel applications. I/O hardware and le system parallelism are the key to bridging this performance gap. Prerequisite to the development of eecient parallel le system is detailed characterization of the I/O demands of parallel applications. In the paper, we present a comparative study of parallel I/O access patterns, commonly found in I/O intensive scientiic applications. The Pablo performance analysis tool and its I/O extensions is a valuable resource in capturing and analyzing the I/O access attributes and their interactions with extant parallel I/O systems. This analysis is instrumental in guiding the development of new application programming interfaces (APIs) for parallel le systems and eeective le system policies that respond to complex application I/O requirements. |
