Abstract
The described technology provides a method including receiving a request from an agent for accessing a cogran and for allocating an agent ID to one of a plurality of SFT entries in a snoop filter (SFT), performing a tag lookup function for a tag of the cogran in the SFT to find a matched SFT entry, wherein the matched SFT entry is tracking the tag of the cogran, determining the number n of agents being tracked by the matched SFT entry, and in response to determining that the number n of agents being tracked by the matched entry is above a threshold, storing a DVT index in the tracking_info field of the matched SFT entry, wherein the DVT index selects a DVT entry in a disaggregated vector table (DVT), wherein the selected DVT entry is configured to hold a tracking vector for tracking the agents that have cached the cogran for the matched SFT entry.
