一类Stencil应用在众核NUMA架构的性能研究
Performance Research of a Class of Stencil Applied in Many-Core NUMA Architecture
摘要
Abstract
[Application Background]Stencil is a typical algorithm for scientific computing such as CFD(Computational Fluid Dynamics),and its memory access performance has attracted attention.The NUMA architecture is widely used in the ARM architecture represented by the Kunpeng 920 processor due to its good scalability.[Methods]Performance analysis tools and benchmark programs are used to test the performance of the Kunpeng platform's memory access and com-munication subsystems.The hot spot analysis and performance test are carried out for the typi-cal stencil application software CCFD V3.0,and the Roofline model is established.[Results]The Kunpeng 920 processor relies on its many-core NUMA architecture.Its single-node float-ing-point performance,peak memory bandwidth,and communication latency are better than that of the Intel Xeon E5-2680v2 and another domestic processor.On a single node,the execution speed of CCFD V3.0 on the Kunpeng platform is about 2～3 times of that of the Intel platform and 1.5～2 times of that of the domestic processor.[Conclusions]The Kunpeng platform based on the ARM architecture is easy in program porting,and its NUMA architecture has advantages for memory-intensive applications such as stencil.关键词
