A method, circuit arrangement, and design structure utilize broadcast prediction data to determine whether to globally broadcast a memory request in a computing system of the type that includes a plurality of nodes, each node including a plurality of processing units. The method includes updating broadcast prediction data for a cache line associated with a first memory request within a hardware-based broadcast prediction data structure in turn associated with a first processing unit in response to the first memory request, the broadcast prediction data for the cache line including data associated with a history of ownership of the cache line. The method further comprises accessing the broadcast prediction data structure and determining whether to perform an early broadcast of a second memory request to a second node based on broadcast prediction data within the broadcast prediction data structure in response to that second memory request associated with the cache line.
