Abstract: We represent a new highly-optimized TWSM algorithm adapted for GPU cluster. We show the scheme of parallelization of the TWSM for several GPUs. Accuracy, stability and efficiency of the algorithm are illustrated by numerical examples for transmission through the W-shaped salt overhang and reflection from smooth interface with strong contrast.

Keywords: seismic modeling, diffraction modeling, high-performance computing, GPU.
