    Abstract: Investigations of a test implementation of the “simple” Kirchhoff method (KIA) for GPU graphics adapters (using OpenCL) have shown that, depending on the GPU hardware available, significant performance improvements can be achieved.\nTherefore, as part of the “Computational Acoustics” research project, the BEAM ray tracing method implemented under C++ was ported for the required acoustic problems (bistatic, monostatic calculations and their combination) for GPUs.\nThe article deals with the challenges encountered, describes the practical experience in the implementation of the complex parallelized algorithm in OpenCL and shows the results achieved and speed advantages compared to conventional high-performance PC workstations using examples of underwater objects.
