基于多核的粗粒度2.5维电磁场正演并行算法
2 .5-Dimensional CSAMT Forward Coarse-Grained Parallel Algorithms Based on Multi-core
摘要
Abstract
A 2.5-dimension controlled source audio-frequency magnetotelluric coarse-grained forward parallel computing algorithm based on multi-core was implemented.This algorithm decomposes the different frequencies to each thread of the CPU core,while the master thread executed the allocation of parallel tasks and slave threads computed the electromagnetic field values of each frequency in parallel.The relationship between the number of cores and parallel efficiency was analyzed.The experiments demonstrate that our parallel algorithm can gain a near-linear speedup of logical cores of CPU,and at the same time,acquire the same data accuracy.关键词
