We study parallel algorithms of Jacobi iteration and DRM based on GPU for separable elliptic equation. Two test cases are performed on GTX 570 platform to verify validity of parallel algorithms. It shows that the maximum speed-up ratio on DOUBLE reaches about 14. And efficiency reaches 53% for Jacobi iteration. Besides,the maximum speed-up ratio on DOUBLE reaches about 3.8. And efficiency reaches 15% for DRM algorithm.

The stopping powers and energy stragglings for implanted ions in strongly coupled degenerate electron gas were investigated using local-field correction dielectric function.The numerical results have shown thst the stopping powers and energy stragglings were considerably increased due to local-field correction at low volecities and high valuse r_s.
