Question 3 refers to the paper "SARC: Sequential Prefetching in Adaptive Replacement Cache" by Gill and Modhn. 3. Suppose that synchronous prefetching is uned with see/Threshold = and degree of sequential rend-shend (size of a group to be prefetched) equnt to 3. Suppose that naynchronous prefetching la ngDuned. Suppose that track 15 is in the cache, and has a sequentin detection counter value of 3. Suppose that track 40 is in the cache, and hos a counter value of 2. Suppose that tracks 16,...,36 nd tracks 41,..,65 are not in the cache. 15 6 a) Suppose that there is a miss on track 41. What happens next using SARC? Fill in the blanks below to indicate which tracks are demand fetched. if any, and which tracks are prefetched, if any, as a result of this miss on track 41. If there are none, write "none" in the blank. Give the counter values of each demand fetched track and each prefetched track. Justify your answer. Explain your answer. Demand fetched track(s) and their counter values: Prefetched track(s) and their counter values:
