【摘要】 近年来,随着计算机体系结构的发展,多核平台的应用越来越广泛。多核平台与并行计算理论结合,以多线程的方式有效的提高了应用程序性能。本文针对图形领域中广为使用的OGRE3D渲染引擎,从多帧渲染、循环迭代、函数调用三个方面进行多线程并行优化,并在多核平台上进行测试。实验结果表明,本文的优化方法是正确的,有效的提高了OGRE3D渲染引擎的性能,从而证明了多核平台和并行计算理论的优越性。更多还原

【Abstract】 In recent years, with the computer architecture’s development, multi-core platform’s application becomes more and more extensive. Combined with the parallel computing theory, multi-core platform greatly improves the application’s performance by the multi-thread parallelization. This paper threads the OGRE 3D render engine, which is widely used in the graphic field, by the 3 steps: multi-frames rendering parallelization, loop iterations parallelization and call of functions parallelization, And then verifies it in the multi-core platform. The results show that the optimization method is correct, and it effectively upgrades the engine’s performance. So this paper verifies the multi-core platform and the parallel computing theory’s advantage, and achieves the research purpose.更多还原
