Abstract:
1. A computer system comprising a plurality of processor clusters, each cluster including a plurality of local nodes and an interconnection controller interconnected by a local point-to-point architecture, each cluster having a local transaction space associated therewith for uniquely identifying locally generated transactions within the cluster, each local transaction space being insufficient for uniquely identifying the associated locally generated transactions within a global transaction space representing the plurality of clusters, wherein the interconnection controller in each cluster is operable to uniquely map selected ones of the locally generated transactions directed to others of the clusters to the global transaction space thereby uniquely identifying the selected locally generated transactions within the global transaction space, the interconnection controller in each cluster further being operable to map remotely generated transactions directed to the local nodes to the local transaction space thereby uniquely identifying the remotely generated transactions within the associated local transaction space.
