摘要
简要介绍了一种新的并行编程标准——ＯｐｅｎＭＰ，通过与其他几种并行编程标准的比较，了解其优越与不足之处。详细介绍了 ＯｐｅｎＭＰ在 ＰＳＵ／ ＮＣＡＲ的中尺度模式ＭＭ５中的运用。分别用 ＯｐｅｎＭＰ并行方式与 ＭＰＩ并行方式在 ＳＧＩ Ｏｒｉｇｉｎ ２０００上进行了并行效能测试。测试结果表明： ＯｐｅｎＭＰ是一种简单、高效的并行编程标准，非常适合于气象科研与业务领域应用。
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.
