Hi Felipe,

I'm gonna assume that you run O3CPU or Minor. Changing cache size changes timing. Changing timing may change the number of loads that get their data from the Store Queue (hence don't access the cache). If you run atomic or timing, however, I'm not exactly sure how to explain it.

Hi all,
One quick question about gem5:
How come when we run a program twice but with different cache sizes (say 2KB and 4KB) we get a different number of total accesses (on both caches)? This should be a property of the program and it should also be independent of the architecture used.

Thanks
