摘要

In order to evaluate performances of OpenMP and MPI on 64-bits shared memory architecture, we made a comparison between OpenMP and MPI on IA64 SMP with NPB2.3 benchmark suite (excluding IS kernel). Assisted by Vtune(TM) Performance Analyzer 7.0, we raised comparisons in execution time, detailed performance data and overheads between these two paradigms, and managed to optimize some of these kernels.
