Abstract:
1. A multiprocessor system comprising: a plurality of processor clusters, wherein each processor cluster contains a cluster interconnect and at least one processor, coupled to the cluster interconnect, that contains an internal processor communication register (PCR) having a plurality of sectors, wherein each processor in the plurality of processor clusters has access to its PCR and can retrieve contents of each sector of the plurality of sectors, and wherein each sector of the plurality of sectors within each PCR is allocated for storing by only a respective one of a plurality of processors within the plurality of processor clusters, and wherein each processor within the plurality of processor clusters updates its associated sector in each PCR within the plurality of processor clusters such that when a sector is updated by its associated processor, each processor containing an internal PCR is enabled to immediately access the updated sector; and a network interconnecting the plurality of processor clusters by which processors in the plurality of processor clusters update their allocated sectors within each PCR within other processor clusters of the plurality of processor clusters by transmitting information over the network utilizing Internet Protocol at a network layer.
