Abstract:In this work we describe a Parallel External Memory System (PEMS) which provides a framework and interface to convert Bulk Synchronous Parallel (BSP) programs into external memory programs based on the theoretical results of [12, 30]. The results in [12, 30] show how to adapt parallel algorithms designed for a large number of processors without disks to smaller, realistic numbers of processors, each with its own disk system. While the theory shows that for selected problems this can be done with the same amount of I/O, asymptotically, as an single processor algorithm, it has not been clear whether this approach is attractive in practice. This work takes a step forward in this regard, showing timing results for sorting and list ranking that are comparable with TPIE and STXXL. Our experiments show that this approach is practical and promising and the run times scale predictable with the number of processors and with the problem size.
