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.

Two dimensional three temperatures energy equation is a kind of very impor-tant partial differential equation. In general, we discrete such equation with full implicit nine points stencil on Lagrange structured grid and generate a non-linear sparse algebraic equation including nine diagonal lines. This paper will discuss the iterative solver for such non-linear equations. We linearize the equations by fixing the coefficient matrix, and iteratively solve the linearized algebraic equation with Krylov subspace iterative method. We have applied the iterative method presented in this paper to the code Lared-Ⅰ for numerical simulation of two dimensional threetemperatures radial fluid dynamics, and have obtained efficient results.
