  • Methods for Achieving Efficient Coherent Access to Data in a Cluster of Data Processing Computing Nodes
    Publication number: 20110137861
    Abstract: A coherency manager provides coherent access to shared data by receiving a copy of updated database data from a host computer through RDMA, the copy including updates to a given database data; storing the copy of the updated database data as a valid copy of the given database data in local memory; invalidating local copies of the given database data on other host computers through RDMA; receiving acknowledgements from the other host computers through RDMA that the local copies of the given database data have been invalidated; and sending an acknowledgement of receipt of the copy of the updated database data to the host computer through RDMA. When the coherency manager receives a request for the valid copy of the given database data from a host computer through RDMA, it retrieves the valid copy of the given database data from the local memory and returns the valid copy through RDMA.

  • System, method, and computer program product for centralized management of an INFINIBAND distributed system area network
    Patent number: 7647396
    Abstract: A method, system, and product in a data processing system are disclosed for providing centralized management of an INFINIBAND distributed system-area network that includes multiple end nodes. A manager application is established in one of the end nodes. An agent application is established in one or more end nodes. Each agent application is independent from the manager application. The manager application maintains a current list of active agent applications and uses the list to manage the agent applications in the end nodes.
