摘要：

In developing a visualization of earth modeling, significant computation lies on integral equations since they come from very high oscillation. We develop the parallel algorithm for this integral equation solver based on Message Passing Interface (MPI) and OpenMP. The solver is based on the job scheduler model to balance loads for each node with threads. In the paper, we also investigate the suitable integration method for magnetic sounding equations. We have chosen five approximation methods for numerical integrations with fixed relative errors. We found that Gaussian Quadrature is the best approximation method for parallel integration of magnetic sounding equation.
