Three-dimensional acoustic parabolic equation model based on GPU processing
* Presenting author
We introduce a three-dimensional acoustic parabolic equation (PE) model based on GPU processing. This model is developed by splitting the full exponential operator in the three-dimensional split-step marching solution in the Cartesian coordinate. Each exponential operator is approximated by the Taylor series and the sum representation of Pade approximation, which gives an opportunity for GPU parallel processing of the 3D PE solver. An advantage of this model is to implement higher-order cross-terms appearing to the operator approximation efficiently. In the talk, we show the computational performance of GPU based PE code with the comparison of a traditional code for several ocean environments.
