How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

As commonly used in two-dimensional magnetotelluric (MT) inversion, Occam inversion method, though featured by its stable convergence and independence on initial model, is relatively poor in time performance, with Gauss-Jordan elimination as one of the biggest time-consuming parts. For symmetrical banded coefficient matrix on two-dimensional consta...
To improve the performance of the Magnetotelluric Occam inversion, by in-depth analysis of the sequential algorithm, we develop a multi-level hybrid parallel computing scheme for MT Occam inversion based on MPI+OpenMP+CUDA and implement it on a small heterogeneous cluster. We implement the parallel algorithm for solving linear equations with Gauss...
