摘 要: 以参数化的硬件线程执行模型对负载可分应用的性能进行了分析与预测.重点讨论包含多个可重构处理单元(RPU)在内计算平台的负载可分调度问题,分析了配置因素对调度结果以及应用处理时间的影响.结果表明,若配置与通信操作不完全重叠,存在最大可用RPU数和最优RPU数,进而可得出优化的调度方案及应用处理时间,指导应用的设计实现. This paper presents a performance analysis and prediction of Divisible Load Application(DLA)based on parameterized execution model of hardware threads.The problem of divisible load scheduling is mainly discussed for a reconfigurable computing platform including multiple Reconfigurable Processing Units(RPUs)and the influence of configuration on load scheduling and optimal processing time is also analyzed.It is proved that there exist maximum RPU number and optimal RPU number when configuration does not completely overlap with communication.An optimal solution for the load scheduling and the processing time is derived for DLA design and implementation.
