Does the global miss rate increase or decrease as the cache size increases? Why? Does this increment or decrement happen for all the benchmarks or does it depend on the different locality grades? What does it happen with the capacity and conflict $($collision$)$ misses when you enlarge the caches? And, what does it happen with the compulsory and coherence misses when you enlarge the caches? Are there conflict misses in these experiments? Why?

In these experiments, it may be observed that for great cache sizes, the miss rate is stabilized. Why? We can also see great differences of miss rate for a concrete increment of cache size. What do these great differences indicate? Do these great differences of miss rate appear at the same point for all the programs? Why?

Compare these results with the results obtained in the Task $2$ of Project $1.$ You can observe that the miss rates are higher for multiprocessor traces than for uniprocessor traces.

Do you think that, in general, parallel programs exhibit more or less spatial and temporal locality than serial programs? Why? Is it due to the shared data?

In conclusion, does the increase of cache size improve the multiprocessor system performance?
