BENCHMARKING CLUSTERS OF WORKSTATIONS THROUGH PARALLEL SORTING AND BSP LIBRARIES

Abstract

We present our experiences in developping and tuning the performance at the user level, of (in core) parallel sorting on homogeneous and non homogeneous clusters with the use of the two available BSP (Bulk Synchronous Parallel model) libraries: BSPLib from Oxford university (UK) and PUB7 from the university of Paderborn (Germany). The paper is mainly about the communication performances of these two libraries and, in more general terms, it compares and summarizes the programming facilities and differences between them.
