Performance comparison of three types of GPU‐accelerated indirect boundary element method for voxel model analysis

Abstract: SUMMARYAn indirect boundary element method that is geared to electrostatic field analysis in voxel models is accelerated by graphics processing units (GPUs). The method considers square walls on cubic voxels as boundary surface elements and uses the fast multipole method (FMM) to analyze large-scale models. On the basis of two conventional CPU codes, three GPU codes are programmed in search of higher computing performance. These GPU codes are designed as follows: In GPU code 1, direct and far fields in the FMM… Show more

“…[11] gives an idea of how to generate lookup table, block density, as well as index buffer for 2D and 3D textures via GPU with simple voxel and marching cube introduction. Hamada [12] introduced indirect fast multipole method-boundary element method for voxel model analysis and applied field for electrical field of biological samples via GPU acceleration and pseudocode template for CUDA kernels of the fast multipole method, along with multiple graphics processing unit execution. Crassin [13] introduced a system that achieves real-time rendering performance for several billion voxels and how the introduced prefiltered geometry model and approximate cone tracing method can achieve blurry effects and real-time indirect lighting.…”
