In this paper, a GPU accelerated three-dimensional finite difference method is presented as an efficient approach of performing fast parallel simulations of composite materials. Using a NVIDIA GeForce 9800 series GPGPU and with an optimized CUDA implementation, a considerable speed-up (>20) was observed for simulations of large size problems. Further performance improvements could be achieved by further efficient data transfer and access between shared memory and global memory, using distributed computing with multiple video cards, and etc.
