为了进一步提高大地电磁三维快速松弛反演的计算效率,在深入分析大地电磁三维快速松弛反演算法的基础上,结合MPI自身的优越性,确定了并行计算的思路,实现了三维快速松弛反演的并行计算。通过理论模型合成数据和实测数据对实现的三维快速松弛反演并行程序进行了试算,分析对比了在多种情况下程序的执行效率。测试结果表明,所实现的三维快速松弛反演并行程序运行结果正确,效率提高明显。此成果在普通微机上实现,推动了大地电磁三维反演技术的实用化,可为其它地球物理三维正反演研究所借鉴。
In order to further improve the computational efficiency of the magnetotelluric 3D rapid relaxation inversion, based on the in-depth analysis of the magnetotelluric 3D rapid relaxation inversion algorithm, combined with the superiority of MPI itself, the idea of parallel computing is confirmed and the three-dimensional fast relaxation inversion Parallel computing. Through the theoretical model synthesis data and the measured data, the three-dimensional fast relaxation inversion parallel program was tested, and the execution efficiency of the program was analyzed and compared. The test results show that the 3D parallel fast relaxation inversion program runs correctly and the efficiency is obviously improved. This achievement is realized on a common microcomputer, which promotes the practical application of the MT3D inversion technique and can be used as a reference for other geophysical 3D inversion research.
