[20/20] In multiprocessor memory systems, lower levels of the memory hierarchy may not be able to be saturated by a single processor but should be able to be saturated by multiple processors working together. Modify the code in Figure 2.32, and run multiple copies at the same time. Can you determine: a. [20] How many actual processors are in your computer system and how many system processors are just additional multithreaded contexts? b. [20] How many memory controllers does your system have?
