【摘要】 对于由p个处理机模块和b根全局总线组成的分布式公用存贮器型多总线多处理机系统,提出处理效率(PE)的张弛迭代公式。应用不动点理论,证明了该公式的收敛性。并将计算结果与仿真结果做了比较,分析了全局总线数6和公用存贮器利用系数ρ对PE的影响,给出了b的取值范围。更多还原

【Abstract】 A relaxation iterative formula is proposed for performance evaluation of distributed common memory multi-bus multiprocessor systems composed of p processor modules and b global buses. The convergence of the formula is proved by using the fixed point theory and comparisons between theoretical and simulation results are made. The effect of the number of global buses b and the common memory utilization facter p on processing efficiency of the. system is analyzed and the range of the proper value of b is given.更多还原
