| 20080215754 | Bridging Data Network Communications - When a packet is sent from a node connected to the network requiring acknowledgements to a node behind the bridge, the original destination address (address of node behind the bridge) is changed. On the driver level, the destination address is replaced with the MAC address of the bridge, and the original destination address is moved to an additional field of the packet. Thus the communication between the sending node and the bridge appears to be point-to-point (from node to bridge). Accordingly, when the bridge receives the packet it is automatically acknowledged from the firmware, and the sending node does not try to resend it. The packet is forwarded to the driver of the bridge. The driver modifies again the received packet by replacing the destination address with the original one found in the “ORIGINAL TO”, additional field and at the same time completely removing that field. Thus the package looks substantially the same as the one originally generated by the application on the sending node. | 2008-09-04 |

The design structure includes a symmetric multiprocessing (SMP) system. The system includes a plurality of nodes. Each of the nodes includes a node controller and a plurality of processors cross-coupled to one another. The system also includes at least one cache directory coupled to each node controller, and, invalid state transition logic coupled to each node controller. The invalid state transition logic includes program code enabled to identify an invalid state transition for a cache line in a local node, to evict a corresponding cache directory entry for the cache line, and to forward an invalid state transition notification to a node controller for a home node for the cache line in order for the home node to evict a corresponding cache directory entry for the cache line. | 2008-09-04 |
| 20080215819 | METHOD, APPARATUS, AND COMPUTER PROGRAM PRODUCT FOR A CACHE COHERENCY PROTOCOL STATE THAT PREDICTS LOCATIONS OF SHARED MEMORY BLOCKS - A method, apparatus, and computer program product are disclosed for reducing the number of unnecessarily broadcast local requests to reduce the latency to access data from remote nodes in an SMP computer system. A shared invalid cache coherency protocol state is defined that predicts whether a memory read request to read data in a shared cache line can be satisfied within a local node. When a cache line is in the shared invalid state, a valid copy of the data is predicted to be located in the local node. When a cache line is in the invalid state and not in the shared invalid state, a valid copy of the data is predicted to be located in one of the remote nodes. | 2008-09-04 |
| 20080215820 | METHOD AND APPARATUS FOR FILTERING MEMORY WRITE SNOOP ACTIVITY IN A DISTRIBUTED SHARED MEMORY COMPUTER - A method and apparatus for filtering memory probe activity for writes in a distributed shared memory computer. In one embodiment, the method may include assigning an uncached directory state to a cache data block in response to evicting the cache data block. In another embodiment, the method may include assigning a remote directory state to a cache data block in response to evicting the cache data block and storing it in a remote cache. In a third embodiment, the method may include assigning a pairwise-shared directory state in response to a second processor node initiating a load operation to a cache data block in a modified cache state in a first processor node. In a fourth embodiment, the method may include assigning a migratory directory state in response to a processor node initiating a store operation to a cache data block in a pairwise-shared cache state. | 2008-09-04 |
| 20080215821 | DATA PROCESSING SYSTEM AND METHOD FOR EFFICIENT COMMUNICATION UTILIZING AN IN COHERENCY STATE - A cache coherent data processing system includes at least first and second coherency domains each including at least one processing unit. The first coherency domain includes a first cache memory, and the second coherency domain includes a coherent second cache memory. The first cache memory within the first coherency domain of the data processing system holds a memory block in a storage location associated with an address tag and a coherency state field. The coherency state field is set to a state that indicates that the address tag is valid, that the storage location does not contain valid data, and that the memory block is likely cached only within the first coherency domain. | 2008-09-04 |
| 20080215822 | PCI Express Enhancements and Extensions - A method and apparatus for enhancing/extending a serial point-to-point interconnect architecture, such as Peripheral Component Interconnect Express (PCIe) is herein described. Temporal and locality caching hints and prefetching hints are provided to improve system wide caching and prefetching. Message codes for atomic operations to arbitrate ownership between system devices/resources are included to allow efficient access/ownership of shared data. Loose transaction ordering provided for while maintaining corresponding transaction priority to memory locations to ensure data integrity and efficient memory access. Active power sub-states and setting thereof is included to allow for more efficient power management. And, caching of device local memory in a host address space, as well as caching of system memory in a device local memory address space is provided for to improve bandwidth and latency for memory accesses. | 2008-09-04 |
| 20080215823 | DATA CONSISTENCY CONTROL SYSTEM AND DATA CONSISTENCY CONTROL METHOD - In a data consistency control system, a plurality of cache agents and at least one home agent are connected to one another by a plurality of networks. The home agent includes a unit issuing a snoop request when receiving an access request. Each of the cache agents includes a unit issuing a snoop response to the home agent when receiving the snoop request, and a unit issuing a snoop retry response. Each of the cache agents also includes a unit causing the snoop response and the snoop retry response to be communicated via different networks. The home agent also includes a unit managing the snoop retry response and a unit reissuing the snoop request by the management unit. | 2008-09-04 |
