Abstract
A system may include a node and an additional node coupled by an inter-node network. The node includes an active device, an interface to the inter-node network, a memory, and an address network coupling the active device, the interface, and the memory. The active device sends an address packet to initiate a transaction to gain an access right to a coherency unit. In response to receiving the address packet, the memory is configured to send a report corresponding to the address packet to the interface if the transaction cannot be satisfied within the node. The interface is configured to ignore the address packet and to send a coherency message requesting the access right to the additional node via the inter-node network in response to the report.
