A non-uniform memory access (NUMA) computer system includes at least a local processing node and a remote processing node, with a node controller, that are coupled to a node interconnect. In response to receipt by the node controller of a request transaction transmitted from the local processing node, via the node interconnect, the node controller at the remote processing node issues the request transaction on the local interconnect. If the request transaction receives a retry response at the remote processing node, the node controller reissues the request transaction on the local interconnect at least once, thus giving the request transaction another opportunity to complete successfully.
