MINIMIZING RETRIES IN A COHERENT FABRIC

Abstract

The described technology provides a method that may be implemented at one of a destination node or a home node (also referred to as a completer node), the method including receiving a transaction request at a destination node of a fabric, determining if a request queue (RQ) of the destination node is full, in response to determining that the RQ is full, determining if a retry command buffer (RCB) is full, in response to determining that the RCB is not full, determining if a number of backlogged transaction requests (RetryRsp count) in a RetryRsp counter is zero, and in response to determining that the RetryRsp count is zero, adding the transaction request to the RCB.
