| 摘 要： | 普通Kriging方法是进行空间降水插值的一种有效方法。然而一方面由于海量数据插值计算量大,另一方面该算法的时间复杂度大,为减少空间降水插值的计算时间,采用OpenMP和MPI混合并行技术,实现Kriging并行算法。在Windows操作系统上搭建并行计算环境,实验数据表明,该并行算法能有效地节省计算时间。

| Abstract: | Kriging algorithm is an effective method of interpolation calculation.On the one hand,consider the large a-mount of massive data interpolation,on the other hand,kriging algorithm is a complex algorithm.In order to improve the calculation speed,using OpenMP and MPI parallel interface library,achieve parallel Kriging algorithm.The parallel compu-ting environment is based on the Windows operating system.Test data shows that the parallel algorithm can effectively save computing time. |
