If S? is a desired speedup value, how can we choose the number of processors P according to Amdahl’s law (10.17)? Prove also that, if ˛>0, the parallel efficiency is a monotonically decreasing function of P as the result of Amdahl’s law. If
? is the acceptable threshold of parallel efficiency, what can be the maximum value of P?
