On a CCNUMA system, the cost of accessing nonlocal memory can limit our ability to utilize multiprocessing effectively. The following table shows the costs associated with access data in local memory versus nonlocal memory and the locality of our application expresses as the proportion of access that are local.
Answer the following questions. Assume that memory accesses are evenly distributed through the application. Also, assume that only a single memory operation can be active during any cycle. State all assumptions about the ordering of local versus nonlocal memory operations.
If on average we need to access memory once every 75 cycles, what is impact on our application?
