    • Efficient support for MPI-IO atomicity based on versioning [2011] (international)

      Abstract: {W}e consider the challenge of building data management systems that meet an important requirement of today's data-intensive {HPC} applications: to provide a high {I}/{O} throughput while supporting highly concurrent data accesses. {I}n this context, many applications rely on {MPI}-{IO} and require atomic, non-contiguous {I}/{O} operations that concurrently access shared data. {I}n most existing implementations the atomicity requirement is often implemented through locking-based schemes, which have proven inefficient, especially for non-contiguous {I}/{O}. {W}e claim that using a versioning-enabled storage backend has the potential to avoid expensive synchronization as exhibited by locking-based schemes, which is much more efficient. {W}e describe a prototype implementation on top of {ROMIO} along this idea, and report on promising experimental results with standard {MPI}-{IO} benchmarks specifically designed to evaluate the performance of non-contiguous, overlapped {I}/{O} accesses under {MPI} atomicity guarantees.
