Based on the multilevel memory architectural high performance characteristics of the most popular microprocessors, this paper summarized and discussed some key techniques for parallelization and optimization of seven typical applied codes and model physical problems under both message passing MPI and shared memory OpenMP standard parallel programming paradigms. Typical benchmark results under six parallel computers are also given in detail in this paper.

3-T heat conduct equation including electron, ion and photon (radiation) temperatures can be used to approximately describe the energy broadcast across multimedia for radial flow dynamics and discover the energy swapping among photon,electron and ion. Owing to the strong nonlinear diffusion coefficients and energy swapping coefficients and strong discontinuous coefficients across media interfaces,this equation is difficult to be solved with high numerical resolution. Based on the parallel adaptive multigrid software framework UG on 2-D unstructured grid, this paper successfully solved such equation with high resolution by combining the finite volume implicit discretization scheme and parallel adaptive multigrid algorithm, and gained much significant results.
