Gene Amdahl, one of the early pioneers in computing, made a simple but insightful observation about the effectiveness of improving the performance of one part of a system. This observation has come to be known as Amdahls law. The main idea is that when we speed up one part of a system, the effect on the overall system performance depends on both how significant this part was and how much it sped up. That law says that if a fraction of the code can be speed up by a factor of k, the total system speedup is S=1(1)+/k The marketing department at your company has promised your customers that the next software release will show a 2.5-fold performance improvement. You have been assigned the task of delivering on that promise. You have determined that only 80.0% of the system can be improved. How much (i.e., what value of k) would you need to improve this part to meet the overall performance target? You can enter a mathematical expression or a single value.
