基于Amdahl定律扩展的多核处理器性能模型研究
Performance Model for Multicore Processor Based on Extended Amdahl's Law
摘要
Abstract
Accounting uneven workload allocation,hardware bounds and communication latency,a performance analytic model is derived based on extended Amdahl''s law for multicore processors.The speedup model can be applied as a guide for hardware design as well as a performance prediction model in multicore processors domain.The design space for the specific multicore processors is explored.According to the results,some suggestions about how to design the specific multicore processors,such as the architecture type (homogenous or heterogeneous),the number of cores integrated in the multicore system,the scale of cores to execute computing workload,and the communication area,are provided to the designers.关键词
