摘要
对F-K算法进行了并行化改进,从而使其可以利用PC-Cluster或者并行计算机多节点计算的资源优势,提高计算速度.比较发现,并行后的计算速度大大提高,在计算时间较长的情况下,并行F-K算法的运算速度基本与处理器的个数成正比,为反演震源参数和地下结构提供了更为快捷的计算工具.
In order to improve computation speed, a parallelized F-K program was built to utilize the multiple CPU PC-Clusters. By comparison it was found that the parallelized program can greatly expedite computation. For a complicated model, parallel F-K computation speed is almost proportional to the number of the processors. This method provides a more convenient tool for inversion of source parameters and underground structures.
