面向ARM64架构多核微处理器的模板计算性能优化研究
Performance optimization of stencil computation on ARM64 multi-core microprocessor
摘要
Abstract
Stencil computation is a class of important calculation kernels widely used in the field ranging from image and video processing to large-scale scientific and engineering simulation and calculation.However,the evaluation of stencil computation on the ARM64 high-performance processor is rare.According to the features of AM-CC X-GENE2 and Phytium FT-1500A,we design an optimization method based on two-dimension bound,which reduces the parallelism overheads of thread scheduling,and increases the Cache hit rate by the thread-CPU bound and thread-data-block bound.Experimental results show that this method can improve the performance of the stencil calculation on ARM64 architecture,and the results of our kernel demonstrate the good scalability on the two ARM64 multi-core microprocessor platforms.关键词
