产出率并行加速比模型

Productivity Parallel Speedup Model

针对并行计算系统的性能度量问题,在产出率度量模型的基础上,建立综合系统可靠性、通信、并行化控制和成本投入要素的产出率并行加速比模型,分析总结模型中各要素影响产出率并行加速比的关键因子,包括容错开销因子、通信开销因子、并行控制开销因子及成本开销因子,对上述关键因子进行模拟实验,以验证该模型的有效性。

Aiming at measurement of parallel computing system performance,based on productivity model,this paper proposes a productivity parallel speedup model,which integrates reliability,communication,parallel control and cost in the view of system scalability.The key factors affect parallel productivity including the factors of fault tolerant overhead,communication overhead,parallel control overhead and cost overhead are analyzed and tested to verify the validity of the model.
