| Abstract: | By the design of new parallel algorithm and the organization of grid mapping, a serial code Lared-Ⅰ has been successfully parallelized for numerical simulations of 2-dimension three temperature hydrodynamics with the message passing programming environment. Moreover, a dynamic load balance method is also designed according to the physical and the code executing characteristics, which can significantly improve the parallel performance. The numerical results under both parallel computing environments are given as well. |
