A system has a single core processor that costs $150. Suppose that adding more cores to the chip costs $10 per additional processor. For this system the value of fs is 0.10.
What will be an ideal response?
If it is considered worthwhile adding cores until the incremental speedup ratio increases by less than 5% over the original (unmodified) performance, what is the optimum number of processors? What percentage increase in cost is required to achieve this performance?
Since there are four extra cores costing $40, the increase in cost is 40/150 = 27%.
