Applying OpenCL technology for modelling seismic processes using grid-characteristic methods

Abstract

This paper is concerned with CUDA and OpenCL technologies used to solve seismic problems in elastic media. We solve the problem of the dynamic wave disturbances spreading in geologic environment in an elastic approach in the two-dimensional case. A grid-characteristic method is used for numerical solution. Performance of problem solving algorithm with the GPU is compared with the performance of solving it on a single core CPU. We also study the influence of various optimizations on the performance of the algorithm. We measured the effectiveness of parallelization on multiple graphics processors.
