摘要:
In one embodiment, a node for a multi-node computer system comprises a coherence directory configured to store coherence states for coherence units in a local memory of the node and a coherence controller configured to receive a coherence request for a requested coherence unit. The requested coherence unit is included in a memory region that includes at least two coherence units, and the coherence controller is configured to read coherence states corresponding to two or more coherence units from the coherence directory responsive to the coherence request. The two or more coherence units are included in a previously-accessed memory region, and the coherence controller is configured to provide the requested coherence unit with a predicted coherence state responsive to the coherence states in the previously accessed memory region.
