Shooting-Bouncing-Rays Technique to Model Mine Tunnels: Algorithm Acceleration
Keywords:computational electromagnetics, GPU acceleration, graphics processing units, high-frequency techniques, high performance computing, parallelization, ray tracing, signal propagation, waveguides, wireless communications
We present and discuss acceleration of a shooting and bouncing rays (SBR) algorithm for ray-tracing electromagnetic analysis of electrically very large structures such as underground mine tunnels at modern wireless communication frequencies. The acceleration is based on the parallelization of the SBR technique on NVIDIA GPUs using the OptiX application programming interface. The results show dramatic speedups of the parallel SBR algorithm compared with serial implementation.
