基于openmp+mpi的2.5维电磁场正演并行化方法
Keywords: 2.5维复电阻率电磁场正演,波数分解,并行计算,混合计算
Abstract:
？针对2.5维复电阻率电磁场正演串行算法的效率瓶颈,研究了一种基于openmp+mpi的混合计算并行化方法。将波数域分解到计算机集群的各节点上,采用mpi对各波数进行并行运算;在各节点内部,对复双共轭梯度法求解线性方程组的过程采用openmp并行运算。波数等间隔分配到各集群节点,以利负载均衡;集群节点读取各自的模型参数,mpi群集传递当前波数的计算结果,以降低通信开销。不同类型和规模算例的实验结果表明,该并行方法不仅能够达到与串行方法等同的精度,而且获得了接近线性的加速比。
