  • NON-UNIFORM MEMORY-AWARE CACHE MANAGEMENT
    Publication number: 20120311269
    Abstract: An apparatus is disclosed for caching memory data in a computer system with multiple system memories. The apparatus comprises a data cache for caching memory data. The apparatus is configured to determine a retention priority for a cache block stored in the data cache. The retention priority is based on a performance characteristic of a system memory from which the cache block is cached.

  • Node translation and protection in a clustered multiprocessor system
    Patent number: 7356026
    Abstract: A method of node translation for communicating over virtual channels in a clustered multiprocessor system using connection descriptors (CDs), which specify the endpoint nodes for virtual connections. The system includes a local processing element node, a remote processing element node and a network interconnect therebetween for sending communications between the processing element nodes. The method includes assigning a CD to specify an endpoint node for a virtual connection, defining a local connection table (LCT) to be accessed with the CD to produce a system node identifier (SNID) of the endpoint node, generating a communication request including the CD, accessing the LCT using the CD of that communication request to produce the SNID for the endpoint node of the connection in response to that request, and sending a memory request to the endpoint node.
