摘要:
In one embodiment, a node comprises at least one processor core and a plurality of coherence units. The processor core is configured to generate an address to access a memory location. The address maps to a first coherence plane of a plurality of coherence planes. Coherence activity is performed within each coherence plane independent of other coherence planes, and a mapping of the address space to the coherence planes is independent of a physical location of the addressed memory in a distributed system memory. Each coherence unit corresponds to a respective coherence plane and is configured to manage coherency for the node and for the respective coherence plane. The coherence units operate independent of each other, and a first coherence unit corresponding to the first coherence plane is coupled to receive the address if external coherency activity is needed to complete the access to the memory location.

In one embodiment, a node comprises a plurality of processor cores, coherency control circuitry coupled to the plurality of processor cores, and at least one coherence unit coupled to the coherency control circuitry. Each processor core is configured to have a plurality of threads active and each processor core includes at least one first level cache. The coherency control circuitry is configured to manage intranode coherency among the plurality of processor cores. The coherency unit is configured to couple to an external interface of the node, and is configured to transmit and receive coherence messages on the external interface to maintain coherency with at least one other node having one or processor cores and a coherence unit. In another embodiment, a system comprises an interconnect and a plurality of nodes coupled to the interconnect.

In one embodiment, a node comprises at least one memory control unit configured to couple to an industry standard memory interface for coupling to a memory; and at least one coherence unit configured to transmit and receive coherence messages to and from other nodes to maintain coherent memory among the nodes. The coherence messages are conveyed on a second interface to which the coherence unit is coupled, wherein the second interface includes at least a physical layer as specified by the industry standard memory interface.

Systems and methods consistent with the present invention may be used as part of determining whether to chargeback a purchase transaction amount to a merchant. To this end, the system may heuristically analyze purchase transaction data to determine which transactions to analyze for chargeback processing. For instance, the system may identify purchase transactions that are likely to qualify for a chargeback. For the identified purchase transactions, the system may then determine an expected value for each transaction in terms of received revenue from chargeback processing and the costs for performing a chargeback. Using the expected values for this transaction data, the system may then prioritize which purchase transactions to review for chargeback to a respective merchant.
