Abstract
Geophysical inversion is an ill-posed problem, resolved partially mostly in 2D or with specific constrains. We analyze the convergence of iterative 3D gravity inversion based in the idea of the CLEAR algorithm in both cases of sequential and parallel processing, focusing in the time and number of iterations depending in number of discretization nodes and number of processors involved. Variations of calculation runtime and number of iterations depending on the size of the model indicate the usefulness of parallel processing for large models of 3D geophysical inversion with simple algorithms. The work is done for the FP7 project HP-SEE.
