Abstract:
This work proposes a technique for constructing vector algorithms for solving the diffraction problem using a finite difference scheme on GPUs. The use of an approach based on the reuse of sums of the differential pattern when solving the D' Alembert equation allowed up to a three-fold reduction in the running time in comparison with the known algorithms.

Keywords:
vector algorithms, wave equation, acceleration of computing.
