Abstract
This paper presents algorithms for optimization and adaptation to the parallel architecture of the procedure which is numerically implementing wavefield propagation in the 3-dimensional geological layers. This procedure is part of the developed highly-optimized software package for diffraction modeling which implements the tip-wave superposition method (TWSM). The paper briefly describes the idea of TWSM, shows the main problems of its implementation and proposes the most efficient algorithms for processing large arrays used by this method.

Key Words
software optimization, high performance computing, GPU, seismic modeling
