Abstract
The described technology provides a method including determining a cacheline sector associated with a snoop filter (SFT) having a plurality of SFT entries, determining a number of cachelines in the identified cacheline sector that are cached by one or more agents, and determining, based on the number of cachelines in the identified cacheline sector that are cached by one or more agents, a number of bits in a bit vector (BV) of one or more of the plurality of SFT entries, wherein the number of bits is required to track the one or more agents.
