【摘要】 采用蒙特卡罗(MC)计算方法,进行核反应粒子输运计算,是业内近十几年发展起来的一种有相对优势的计算方法。本文针对并行计算过程中数据初始化、计算任务分配、计算结果归约、计算结果一致性、程序功能一致性等关键问题进行了多种算法优劣的比较以及程序实现过程中的难点进行了分析,最终给出了测试结果和研究结论。结果表明,MC算法在粒子输运计算过程中有着相当好的计算效率。更多还原

【Abstract】 Monte Carlo(MC) parallel calculation have been developed in nearly decades,which is taken an important role and a comparative advantage in particle transportation calculations.Considering the data initialization,the allotment of mission,the calculation reduce,the consistency of result and the function of program consistency,this paper compared the advantages and disadvantages of various calculations,and ana-lyzed the difficulties encountered during the execution of the procedures.Ultimately the test and research re-sults are shown.The results showed that MC calculation is with great efficiency for the particle transfer cal-culation.更多还原
