SPACE: Sharing pattern-based directory coherence for multicore scalability
An important challenge in multicore processors is the maintenance of cache coherence in a scalable manner. Directory-based protocols save bandwidth and achieve scalability by associating information about sharer cores with every cache block. As the number of cores and cache sizes increase, the directory itself adds significant area and energy overheads.
