Quantitative metrics for parallelism
问题 Some parameters have been described in the Advanced computer architecture book by Hwang, e.g Speedup, Efficiency, Redundancy, Utilization and Quality as shown in the picture below. I understand all and partially understand the last parameter, quality. The question is, why quality has inverse relationship with the redundancy. As said, redundancy shows the matching between software parallelism and the hardware. For example, one processor runs one unit instruction, therefore, O(1)=1. By O(n) we
