Non-uniform memory access (numa) data processing system that speculatively issues requests on a node interconnect

Abstract From the Canadian patent

The invention relates to memory access and provided non-uniform memory access (NUMA), data processing system includes a node interconnect to which at least a first processing node and a, second processing node are coupled. The first and the second processing nodes each include a local, interconnect, a processor coupled to the local interconnect a system memory , coupled to the local interconnect, and a node controller interposed between the local interconnect and the node, interconnect. In order to reduce communication latency the node controller of , the first processing node speculatively transmits request transactions received from the local interconnect of the first, processing …
