The three-dimensional HF Raytrace parallel compute is studied using the high performance computer of distributing share storage architecture. Several factors which must be considered when the program is executed are presented by analyzing the three-dimensional HF Raytrace serial program, and then the HF Raytrace algorithm is simulated using OpenMP. The simulation results indicate that the running speed is improved enormously, which shows the effectivity of the proposed method.
