Ray-tracing algorithm needs a great deal of computation time. To improve its efficiency, two kinds of parallel ray-tracing algorithm: Peer to Peer Model (PPM) and Master/Slaves Model (MSM) are presented in this paper. Propagation prediction simulation in urban microcellular environments is made in LAN workstation cluster by using MPI parallel functions library. The comparison among numeric results indicates that the parallel algorithm considerably reduces the computation time without losing precision, and that the MSM can achieve better parallel speedup gain and load balancing than PPM.
