Some Study on Application of OpenMP in Mesoscale Meteorological Model-MM5
OpenMP在MM5中尺度模式中的应用试验

A new parallel programming standard-OpenMP is introduced in the beginning of this ar- ticle. Its advantage and disadvantage are known through comparison with some other parallel programming standards. The application of OpenMP in MM5 of PSU / NCAR is presented in detail. The parallel performance of both OpenMP and MPI have been tested on SGI Origin 2000. The result show that OpenMP is a simple and efficient parallel programming standard and especially suitable for meteorological sciences field.
