Abstract
Investigations of a test implementation of the “simple” Kirchhoff approximation method (KIA) for GPU graphics adapters (using OpenCL) have shown that, depending on the GPU hardware available, significant performance improvements can be achieved. Therefore, as part of the “Computational Acoustics” research project, the BEAM ray tracing method, originally implemented in C++, was ported to address the required acoustic problems (bistatic, monostatic calculations and their combination).
This article discusses the challenges encountered during this process, shares the practical experiences implementing the complex parallelized algorithm in OpenCL and shows the results achieved. It also highlights the speed advantages compared to conventional high-performance PC workstations using examples of underwater objects.
