A. Increasing the block size of a cache always reduces the cache miss rate by increasing the chance to exploit spatial locality. [ T / F ]
False. 블락 사이즈가 너무 커지면 캐시 블락이 몇 개 못 들어가서 miss rate가 높아짐.
B. Increasing the cache size does not reduce coherence misses in shared memory multiprocessors. [T/F]
True. 캐시에 들어있는게 많으니까 invalidation이 늘어남.
C. Increasing the block size does not increase coherence misses in shared memory multiprocessors. [ T / F ]
False. 여러 프로세스가 한 블락에 접근할 확률이 높아서져 coherence miss 증가.
