The invention relates to a snoop filter device, a node controller, a multicomponent computer system, a computer-implemented method, a data processing system and a computer-readable storage medium aiming at enabling improved tracking of a scalable number of cache elements in multiprocessor systems. The invention involves scaling of a snoop filter device according to the number of cache elements that it is desirable to track.

Snoop filter scalability

The invention relates to a device for use in maintaining cache coherence in a multiprocessor computing system. The snoop filter device is connectable with a plurality of cache elements, where each cache element comprises a number of cache agents. The snoop filter device comprises a plurality of snoop filter storage locations, where each snoop filter storage location is mapped to one cache element.
