层次分解并行计算法在TOVS资料中尺度分析中的应用

The Application of Level-separating Parallel Algorithm to TOVS Data Analysis

摘要: 应用层次分解法在IBM4381-P03型双CPU计算机上，对NOAA-11极轨气象卫星的垂直探测器（TOVS）反演产品中的15个标准气压层上的高度及温、湿度资料进行并行的中尺度客观分析计算。其结果表明：并行计算比串行计算节省作业的执行时间（Execute Time）45%—62%，节省作业的CPU时间（Central Process Unit）约40%，其加速比为3.28。

Abstract: This report discussed how to apply Barnes’ method to the parallel analysis algorithm of 15 level retrieval data from the polar-orbiting satellite NOAA-11 TOVS information, via the level-separating on the IBM4381-P03 with dual CPU at NSMC. The computing results show the speed-up ratio can be reached 3.28.
