Abstract :
In this paper, we introduced three prototypes of GPGPU solutions on NVidia GeForce8800GT for a practical Pre-stack Kirchhoff Time Migration program. We presented how to re-design and re-implement the original CPU code to efficiency GPU code. The prototypes are more than at most 7.2 times faster than its CPU version on Intelpsilas P4 3.0G.
