JCOGIN: a Monte Carlo particle transport infrastructure with combinatorial geometry
-
摘要: 介绍了JCOGIN支撑软件框架层次式、模块化的体系结构及其核心数据结构。这些使得JCOGIN软件框架能够支撑大规模复杂几何的蒙特卡罗（MC）粒子输运并行计算。同时介绍了在JCOGIN支撑软件框架下研发的JMCT程序，并进行了性能测试，在2万处理器核上模拟20亿粒子，并行效率达到70%。Abstract: This paper introduces a software infrastructure named J combinatorial geometry Monte Carlo particle transport infrastructure (JCOGIN). The architecture and data structure of JCOGIN and the optimization of computing on the combinatorial geometry are present. Based on JCOGIN, a program used for simulating 3D neutron-photon coupling transport named J Monte Carlo transport (JMCT) is developed, with its performance tested. Results show that JMCT reaches the parallel efficiency 70% in the simulation of 2 billion particles on 20 480 cores for an outside source.
