dc.description.abstract | In this paper we describe the parallelization of the multi-zone code versions of the NAS Parallel Benchmarks employing multi-level OpenMP parallelism. For our study, we use the NanosCompiler that supports nesting of OpenMP directives and provides clauses to control the grouping of threads, load balancing, and synchronization. We report the benchmark results, compare the timings with those of different hybrid parallelization paradigms (MPI+OpenMP and MLP) and discuss OpenMP implementation issues that affect the performance of multi-level parallel applications. |
