Parallelization Method for Three Dimensional MOC Calculation
-
摘要: 设计了基于角度并行的三维特征线的并行算法。同时，为提高并行效率，采用了角度预分组和射线组合的策略，使通信量达到最小，并应用到中子输运方程的三维特征线计算程序TCM中。数值结果表明：角度并行方法和串行方法的结果完全一致，在采用了通信优化和负载平衡策略后，并行效率得到了显著提高。Abstract: A parallelization method based on angular decomposition for the three dimensional MOC was designed. To improve the parallel efficiency, the directions were pre-grouped and the groups were assembled to minimize the communication. The improved parallelization method was applied to the three dimensional MOC code TCM. The numerical results show that the calculation results of parallelization method are agreed with serial calculation results. The parallel efficiency gets obvious increase after the communication optimized and load balance.
