SIMULATION STUDY FOR PERFORMANCE ANALYSIS OF MULTI-BUS MULTIPROCESSOR SYSTEMS

对四种典型的公用存贮器型多总线多处理机系统,给出处理效率的仿真估计方法。该方法适用于任意规模的系统。同时,访问公用存贮器的请求间隔和一次公用存贮器的操作时间都可以服从任意分布,并且处理机可按任意概率访问各公用存贮器模块。

A simulation method is proposed for estimating processing power of four typical common memory multi-bus multiprocessor systems. The method is applicable to systems with any architecture parameters. The duration between the completion of a request and the. generation of the next one to the common memory and the duration of an access by a processor to the common memory can be random variables with any distribution. The probability of a request for access from a, processor in a common memory module can also be a random variable with any distribution.
