摘要
为了充分利用多核处理器的硬件资源和计算能力,提出了基于多核并行编程技术的图形数据文件加载优化方案。根据图形数据文件加载的特点,由传统的串行程序改为并行程序,利用多核并行编程模型的思想,找出程序的热点和瓶颈,对其进行优化。实验结果表明,当图形符号数量达到一定数量级之后,优化过后的执行时间较原来串行程序有明显缩短,提高了程序的加速性能,取得了良好的效果。
In order to take full advantage of multi--core processor＇s hardware resources and computing capacity, applica- tion of multi--core parallel programming technology in the graphical data file load optimization scheme is provided. Ac cording to the characteristic of graphical data file load, from the traditional serial program instead of parallel program. U sing the ideas of a parallel programming model, find the program＇s hotspot and bottleneck, and then optimize it. Experi mental results show that, the optimization of the execution time was shortened obviously compared to the orginal, when the quantity of graphic symbol reaches a certain magnitude, and the program also increased speedup performance, which achieves good effect.
