Firstly, with the discusses of main ingredients to exert the peak float performance for currently high performance mirco-processors in detail, this paper analyzed the principal motivations for the speedup of parallel applied codes under the parallel computers consisted of the these micro-processors. Secondly, this paper presented a suite of performance evaluations rules for parallel codes, which can reveal the overall numerical and parallel performance with respect to the serial codes, pose the performance improving strategies, explain exactly the reasons for super-linear Speedup. The numerical experimential results of two realistic applied codes under two parallel computer are also given in this paper.

In this paper, the difference method for the equation of filtration type with convection is considered. The explicit scheme with artificial viscosity is given, then the convergence of the difference solution is proved by the method of discrete functional analysis. Meanwhile, the existence of the weak solution of the differential equation is obtained. At last, the numerical examples reveal the important properties of the solution to the equation of filtration type.
