多总线及纵横开关互连的多处理器系统性能分析

Performance Analysis of Multiprocessor Systems of Multibus and Crossbar Interconnection

本文对我们正在研究中的一种多处理器系统的性能进行了分析,对该系统的存贮器带宽以及处理器的平均利用率进行了较详细的推导,并给出了统计、分析结果。纵横开关的互连方式,虽然在实现上成本开销较大,但对系统的性能来说却是最优的。

In this paper, the performance of a kind of multiprocessor systems being re-searched is analysed. Bandwidth expressions and the average utilization of a processor arederived and the analysis results are given. It is concluded that though the crossbarinterconnection is expensive, it has a far better performance in multiprocessor systems.
