Abstract :
This paper presents a computational parallelization strategy applied in propagation models based on 3D ray-tracing techniques. This approach considers that the rays are independent from each other, what allows a uniform division of the tasks by equal and random distribution of rays among the parallel computer nodes. The strategy efficiency is proved by simulation where the results are discussed.
