摘要
NNW-FlowStar(简称FlowStar)是依托国家数值风洞工程研发的一款工业级通用非结构计算流体力学软件,包含了丰富的数值模型和复杂的功能模块,已广泛应用于航空航天和其他相关领域.随着高性能计算机体系结构的发展,在HPC系统上优化FlowStar等大型工业级CFD软件越发困难.鉴于此,依托典型HPC平台,针对FlowStar软件,从计算、通信、访存等角度对FlowStar性能特征进行了深入的测试和分析,可帮助研究人员更好地理解HPC系统上复杂CFD软件运行性能特征,为后续FlowStar软件的并行计算和性能优化提供参考.该研究对其他非结构CFD软件并行计算、性能优化以及HPC与CFD融合发展也具有借鉴意义.
Abstract
Based on the National Numerical Wind Tunnel Engineering Project,NNW-FlowStar is an industrial general-purpose unstructured computational fluid dynamics software.It incorporates a diverse range of numerical models and intricate functional modules,and it has been widely applied in the aerospace and other relevant fields.With the advancement of high-performance computer architectures,optimizing large-scale industrial-grade CFD software such as FlowStar on HPC systems has become increasingly challenging on HPC systems.Leveraging typical HPC platform,this work conducts in-depth testing and analysis through the approach of the computation,communication,and memory access characteristics.It helps researchers to understand the performance characteristics of complex CFD software on HPC systems deeply and provids recommendations and references for future futher parallel computing and performance optimization of FlowStar.This study serves as a reference for parallel computing and performance optimization in other non-structured CFD software and can also contribute to the integration and development of HPC and CFD.
