Directory-based Cache Coherence

Directory-based Cache Coherence. Large-scale multiprocessors. Directory contents. for each memory block, the directory shows: is it cached? if cached, where? if cached, clean or dirty? full directory has complete info for all blocks n processor coherence => (n+1) bit vector. Terminology.
