Parallel Computation for Inversion Algorithm of 2D ZTEM

ZTEM refers to the Z-axis tipper electromagnetic method. The method is an airborne magnetotelluric sounding based on difference in rocks’ resistivity using native field. effective exploring large-scale structures when ground fluctuant. paper introduces inversion algorithm of 2D named conjugate gradient This method, which avoids solving Jacobi matrix, very but not enough model divided into a big grid. study can perform further computation parallel and then receive processed data. We compare results serial with result algorithm, proves that correct. When number processes between three six, speedup ratio 1.74 3.19. It improves effectiveness ZTEM.
