English Abstract片内多核已成为延长摩尔定律的方式,并行算法设计、编程模型、编译器和运行时系统都需要利用计算模型进行分析.现有多核模型对线程间共享缓存等资源的竞争已有较精确的模型,但是对于线程间数据共享考虑较少.提出线程间共享缓存的横向局部性和任务共享率概念,基于此扩展串行存储层次模型RAM(h),提出考虑任务共享率的多核并行计算模型MRAM(h).

AbstractAlmost all modern CPUs are multi-cores with shared cache on chip.A number of models have been proposed for predicting the shared cache contention,but few of them consider the influence of shared cache sharing.This paper proposed horizontal locality and task shared ratio,and then proposed a parallel computational model for multi-core architecture,which can be used by parallel algorithm,compiler,parallel programming model and runtime system.
