Cell异构多核处理器上流水并行优化技术

摘要

This paper presented thread synchronous pipeline parallel and iteration synchronous pipeline parallel optimization techniques on Cell processor to improve application performance by taking advantage of heterogeneous muhicore. Conducted the experiments on Cell processor on IS, EP, LD from NAS benchmarks and MOLDYN from SPEC2001. And the evaluations indicate that the proposed strategy significantly increases ihe execution speed of critical and flush operations and increases the speeds greately.%针对如何发挥异构多核处理器的优势从而提高程序执行效率的问题,提出了Cell异构多核处理器上实现线程同步流水并行和迭代同步流水并行两种优化技术,该优化技术可以有效地提高非规则写和控制结构非规则的执行速度.通过在Cell处理器上对NAS benchmarks中的IS、EP、LU以及SPEC2001中的MOLDYN进行测试,结果表明该流水并行方案有效地改善了临界区和flush操作的执行效率,明显地提高了程序的执行速度.
