Assume thаt yоur emplоyer аsks yоu to improve the performаnce of a banking application by porting it to a shared memory parallel computing system.  As a first approximation in your analysis assume that the system has infinite memory bandwidth. Your banking application has a spends a total of 3.75% of the time accessing memory on a single processor system using the same type of CPU  (assume that only memory accesses and computation contribute significantly to the program performance). The parallel computing platform vendor offers a two (2) processor configuration, an four(4) processor configuration, an eight (8) processor configuration, and a sixteen (16) processor configuration. (a) Would you recommend the purchase of such a parallel system to your employer? (b) If so, which processor configuration would you recommend? (c) If you could have any number of processors in the system, and given the assumptions listed above, what number of processors (denoted N) would achieve the maximum speedup of your application? (d) Given the number of processors you determined for part (c) what would be the maximum speedup possible in such a system?
