摘要:在基于分布共享存储结构的高性能计算机上,研究三维短波射线追踪的并行化计算。通过对三维射线追踪串行程序的分析,给出了程序在并行计算时需要考虑的因素,最后采用OpenMP的并行计算技术,对短波射线追踪算法进行了仿真计算。仿真结果表明运行速度得到了大幅度的提高,证明了该算法的有效性。
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.
