Exercise 7.20 Benchmarking is a fi eld of study that involves identifying representative workloads to run on specifi c computing plat forms in order to be able to objectively compare performance of one system to another. In this exercise we will com pare two classes of benchmarks: the Whetstone CPU benchmark and the PARSEC benchmark suite. Select one program from PARSEC. All programs should be freely available on the Internet. Consider running multiple copies of Whetstone versus running the PARSEC benchmark on any of the systems described in Section 7.11.

7.20.1 [60] <7.9> What is inherently different between these two classes of workload when run on these multicore systems?

7.20.2 [60] <7.9, 7.10> In terms of the Roofl ine Model, how dependent will the results you obtain be when running these benchmarks be on the amount of sharing and synchronization present in the workload used?
