The compatibility of a nine-point difference scheme is studied in this *** on this result, a new nine-point difference scheme is suggested for the nu-merical solution of nonlinear diffusion equation. The new scheme keeps the same advantages of the original one, i.e., simple in computation and easy to be imple-mented. Furthermore, the new scheme is more accurate than the original one if the mesh is non-smooth and high skewed, which is most important for Lagrange method in computational fluid dynamics.

The Monte Carlo method is used to simulate unsteady-state particle transport calculations. Due to the computational time existing obviously difference among the different steps and I/O percentage is rated high, it results in the parallel com-putation efficiency down if the fix processors are used in each step. So parallel I/O and the adaptive parallel algorithms are developed. The good results and high speedup are obtained.
