If on average we need to access memory once every 50 cycles, what is impact on our application?

On a CC-NUMA system, the cost of accessing non-local memory can limit our ability to utilize multiprocessing effectively. The following table shows the costs associated with access data in local memory versus non-local 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 non-local memory operations.

Local load/store (cycle) 25 Non-local load/store (cycles) 200 % local accesses 20
