基于GPU的加锁并行化非结构网格生成方法研究
Locking paralleled GPU-based method research for unstructured mesh generation
摘要
Abstract
Defects of consuming time and memory consist in unstructured mesh generation. This paper proposes a novel approach, terming GPU-PDMG, which is GPU parallel unstructured mesh generation based on the framework of CUDA. The technology combines the high-speed parallel GPU and advantages of Delaunay triangulation. It develops a method of locking parallel area dividing, using the CUDA programming model on nVidia GPUs. By analyzing the tested examples’ speedup rate and efficiency, it has evaluated their computing performance. This result is identified in NACA0012 and multi-element airfoil experiment with both the analysis of speedup rate and efficiency and GPU-PDMG is better than any existing GPU algorithms.关键词
