Abstract: A symmetric multi-processing (SMP) processor includes a primary interconnect trunk for communication of information between multiple compute elements situated along the primary interconnect trunk. The processor also includes a secondary interconnected trunk that may be oriented perpendicular with respect to the primary interconnect trunk. The secondary interconnect trunk communicates information off-chip via a number of I/O interfaces at the perimeter of the processor chip. The I/O interfaces may be distributed uniformly along portions of the perimeter.

Abstract: An integrated circuit (IC) processor chip apparatus includes multiple processor chips on a substrate. At least one of the multiple processor chips includes a die with a primary interconnect trunk for communication of information between multiple compute elements situated along the primary interconnect trunk. That multiple processor chip includes a secondary interconnected trunk that may be oriented perpendicular with respect to the primary interconnect trunk. The secondary interconnect trunk communicates information off-chip via a number of I/O interfaces at the perimeter of that multiple processor chip. The I/O interfaces may be distributed uniformly along portions of the perimeter of that multiple processor chip.

Abstract: A data processing system includes a memory controller of a system memory that receives first and second castout operations both specifying a same address. In response to receiving said first and second castout operations, the memory controller performs a single update to the system memory.

Abstract: A method for supporting software partition and dynamic reconfiguration within a non-uniform memory access (NUMA) computer system is disclosed. A NUMA computer system includes multiple nodes coupled to an interconnect. Each of the nodes includes a NUMA bridge, a local system memory, and at least one processor having at least a local cache memory. Multiple groups of software partitions are formed within the NUMA computer system, and each of the software partitions is formed by a subset of the nodes. A destination map table is provided in a NUMA bridge of each of the nodes for keeping track of the nodes within a software partition. A command is forwarded to only the nodes within a software partition.
