Abstract

In this paper, a 2.5-D controlled source audio-frequency magnetotelluric (CSAMT) reversed parallel method based on multi-core CPU is achieved, aiming to the low efficiency of the large-scale computation in geophysical exploration. This parallel algorithm allocates the different waves to each thread of cores under the coarse-gained mode. The master thread deal with all parallel tasks and other slave threads compute the electromagnetic field values of each wave in parallel Fork-join model. The experiments demonstrate that our parallel algorithm can not only acquire the effective data accuracy, but also obtain about three times than the serial version.
