In this paper, the convergence of discrete flux in the difference scheme for the linear parabolic equation with discontinuous coefficients is disucssed. It is shown that the discrete flux of the difference scheme tends to the continuous flux of the differential equation in the sense of the maximum norm and the rate of convergence is O( r+ h1/2).

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.
