Accelerating koblinger's method of compton scattering on GPU

Graphics Processing Unit (GPU), originally developed for real-time, high-definition 3D graphics in computer games, now provides great faculty in solving scientific applications. The Compton scattering is an important procedure of particle transport. This paper focuses on accelerating the Koblinger's method of Compton scattering on GPU. Koblinger's method is mapped onto the thread execution model of GPU and the massive fine GPU thread mechanism is used in the implementation. The experimental results show NVIDIA M2050 GPU is 8.39-20.36 times faster than Intel Xeon X5670 and X5355 chips.
