摘　　要：本文采用有限元方法,在Win7操作系统下,基于Open MP并行编程模式实现了任意频点数的大地电磁二维正演并行化。验证并行程序的正确性后,又对一个模型进行了计算。结果表明,当开启4个线程时两者都达到了2.3-2.6倍的加速比。事实证明对于多核单机来说,Open MP是一种简单有效的并行方法,可以充分利用多核的处理能力。points based on In this paper, we carry out the magnetotelluric 2D forward parallelization of arbitrary frequency OpenMP parallel programming model under Win7 system with infinite element method. After the verification of parallel program correctness, another model calculation is carried out. The result shows the 2. 3-2. 6 times the acceleration ratio of them is achieved when 4 threads are open. The fact confirms for the multi-core stan- dalone, OpenMP parallel method is simple and effective, which can full use the multi-core processing capacity.
