Amdаhl’s Lаw Yоu аre tasked tо оptimize a machine learning application on Hadoop. This application has a map stage and a reduce stage. Before optimization, the map stage accounts for 60% of the execution time, whereas the reduce stage accounts for 40%. For the map stage, you can optimize it to use a cluster with 120 CPU cores, with an expected speedup of 120. For the reduce stage, you can optimize it to use GPU processors, with an expected speedup of 40. Limited by time, you can only choose one stage to optimize. Which stage should you choose? Please justify your answer.
