A New Fast Forward Modeling Algorithm for Gravity Anomaly of Prism

摘要：

　　In this abstract, a new fast algorithm for gravity anomaly forward calculation of prism is presented, which consists of both serial and parallel parts.The derivation of new equation starts from the integral and Taylor series expansion is used to transform the integral kernel.Compared with normal algorithms, the newly proposed forward modeling algorithm contains a simpler equation and thus reduces the computing time.Parallel programming is used to further speed up.As the forwarding is one of the data parallel problems, graphics processing unit (GPU) is adopted in the implement of the algorithm.In the synthetic data test, it is proved that the new forward modeling algorithm could be more than 23 times faster than normal algorithms without parallel programming.
