  • Iterative exchange communication
    Patent number: 8473966
    Abstract: An inter-processor communication approach is applicable to a message passing pattern called iterative exchange. In such patterns, two processors exchange messages, then perform a computation, and then this process is repeated. If two sets of send and receive buffers are used, then it is possible to guarantee that a receive buffer on the receiver's side is always available to receive the message. A message passing system controls which buffers are used for sending and receiving. These buffers are registered beforehand, thereby avoiding repeated registration at the time messages are sent. The sender is initially informed of all the possible receive buffers that the receiver will use, and the sender then uses these receive buffers alternately. Examples of this approach can avoid the use of multiple-step rendezvous protocols, memory copies, and memory registrations when a message needs to be sent.

  • Scalable hardware mechanism to implement time outs for pending POP requests to blocking work queues
    Patent number: 8385354
    Abstract: Methods and apparatus for minimizing resources for handling time-outs of read requests to a work queue in a work queue memory are described. According to one embodiment of the invention, a work queue execution engine receives a first read request when the work queue is configured in a blocking mode and is empty. A time-out timer is started in response to receiving the first read request. The work queue execution engine receives a second read request while the first read request is still pending, and the work queue is still empty. When the time-out timer expires for the first read request, the work queue execution engine sends an error response for the first read request and restarts the time-out timer for the second read request taking into account an amount of time the second read request has already been pending.

  • Cache management
    Patent number: 8370850
    Abstract: A number of applications can be run by the computing system. Such applications can execute independently from each other and can also each independently manage a corresponding set of content stored on a local storage device (LSD). One of the advantages presented by the invention is the ability of the LSD to inform one application of the content made available on the LSD by another one of the applications even though the applications have no relationship to each other. In this way, a synergy between the independent applications can be achieved providing a co-operative environment that can result in, for example, improved operation of the computing system, improved resource (i.e., memory, bandwidth, processing) allocation and use, and other factors.
