—There are two dominant schemes of cache-coherence protocols in use today, namely snoopy-and directory-based. In snoopy-based systems, all coherence transactions are broadcast and therefore seen by all processors in the system. On the other hand, in directory-based systems, processors unicast requests to the home directory, leading to lesser bandwidth utilization. This paper studies the performance of these two classes of coherence protocols, under varying parameters such as the number of… Expand
