  • Negating initiative for select entries from a shared, strictly FIFO initiative queue
    Patent number: 8793699
    Abstract: A computer program product, apparatus and method for negating initiative for select entries from a shared, strictly FIFO initiative queue in a multi-tasking multi-processor environment. An exemplary embodiment includes a computer program product for negating initiative for select entries from a shared initiative queue in a multi-tasking multi-processor environment, the computer program product including a tangible storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for performing a method including identifying an element within the environment that has failed and recovered, not removing the element from the shared initiative queue and entering a boundary element entry into the shared initiative queue.
    Type: Grant

    Date of Patent: July 29, 2014
    Assignee: International Business Machines Corporation
    Inventors: Richard K. Errickson, Geoffrey A. Crew, Welela Haileselaissie, Robert M. Whalen, Jr.
  • Discovery of a virtual topology in a multi-tasking multi-processor environment
    Patent number: 7962564
    Abstract: A computer program product, apparatus and method for identifying processors in a multi-tasking multiprocessor network, the computer program product including a tangible storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for performing a method including storing a service record for a port to which an LID has been assigned, retrieving service records for nodes to which channel paths may connect, retrieving path records that provide address destinations for the nodes identified in the service records, initiating channel initialization for the channel paths defined for the port and removing the service record for the port.
