ABSTRACT:
In one embodiment, a first node comprises at least one memory request source and a node controller coupled to the memory request source. The node controller comprises a remote hit predictor configured to predict a second node to have a coherent copy of a block addressed by a memory request generated by the memory request source, and the node controller is configured to issued a speculative probe to the second node responsive to the prediction and to the memory request.
