Before revision: Coarse bit vector format Diagram of coarse bit vector directory format The coarse bit vector format has a similar structure to the full bit vector format, though rather than tracking one bit per processor for every cache line, the directory groups several processors into nodes, storing whether a cache line is stored in a node rather than a line .
