This paper summarizes the overseas research situation of accelerating Computational Fluid Dynamics(CFD) codes using memory hierarchy techniques.The influence of Cache-friendly method on code efficiency is studied by means of analysis of modern CPU Cache structure.Three dimensional multi-block CFD FORTRAN code is optimized by two methods based on Cache-friendly method.A 3D optimized LU-SGS algorithm is presented.The numerical experiments executed in three kinds of microprocessors indicate that the running time of optimized code is from 20 percent to 50 percent of the original code.
