FMM算法中问题规模与空间划分的关系分析
Analysis on relation between question scale and expansion in FMM
摘要
Abstract
According to the calculation theory of FMM algorithm,and considering its parallel optimization and compiler optimization , this paper divides this algorithm into different sub-modules.The computing characteristics of every sub-modules, including calculation load,parallelism,communication and storage,are analyzed in detail.Based on the deep analysis of relationship between the N-Body question scale and octree level,a strategy of hierarchical space decomposition associating with ques-' tion scale is presented.The experiments validate the correctness and feasibility of the presented strategy.关键词
