【摘要】 首先给出了循环最大加速比的定义，它是循环体中隐含并行性大小的度量，并且讨论Ｄｏ循环的各种类型和它们的相关性以及隐含的并行性．在异构环境中，如何开发这些并行性，文中给出了几种方法，这就是异构计算消除串行瓶颈，异构 Ｄｏ－ａｌｌ－ｌｏｏｐ调度，异构 Ｄｏ－ａ－ｃｒｏｓｓ调度．无论在理论分析还是在实验结果上，这些方法所得得的计算性能都优于同构计算．更多还原

【Abstract】 In this paper, the definition of maximum loop speedup has been presented, which is the metric of parallelism hidden in loop body. the the classes of Do-loop and their dependence as well as the parallelism they contained have been studied. How to exploit such parallelism under heterogeneous computing environment? The several approaches have been proposed in this paper, which are eliminating serial bottleneck by means of heterogeneous computing, heterogeneous Do-all-loop scheduling, heterogeneous Do- across scheduling. We find that, not only on theoretical analysis but also on experimental results, these schemes acquire better performance than in homogeneous computing.更多还原
