一种等值线填充并行算法

Parallel algorithm of contour renderling

通过获得的计算机CPU个数对要形成的网格场进行子区域划分,对各子区域用反距离加权插值法,双线形插值方法将离散气象数据格点化后形成网格数据场,对各子区域进行OPENMP的并行算法处理形成等值线填色场。实验结果表明,并行计算使系统的处理速度有较大提高。

According to the obtained CPU number of computer, element grid field is made and sub-region is pro- cessed. For these sub-regions, with inverse distance weighted interpolation method and dual linear interpolation method, meteorological data grid is processed and data field is formed. And for those sub-regions, with parallel algo- rithm of OPENMP, contour rendering field is formed. Experimental results show that the weather data processing speed is greatly enhanced by parallel computing.
