Abstract: Embodiments relate to implementing a coherence protocol. An aspect includes sending a request for data to a remote processor and receiving by a processor a response from the remote processor. The response has a transaction status of a remote transaction on the remote processor. The processor adds the transaction status of the remote transaction on the remote processor in a local transaction interference tracking table.
