摘要：
A system comprises a first node including data having an associated state. The associated state of the data at the first node is a modified state. The system also comprises a second node operative to provide a non-migratory source broadcast request for the data. The first node is operative in response to the non-migratory source broadcast request to provide the data to the second node and to transition the associated state of the data at the first node from the modified state to an owner state without updating memory. The second node is operative to receive the data from the first node and assign a shared state to an associated state of the data at the second node.
