  • Patent number: 9195504
    Abstract: A method for data transfer in a data processing system, and corresponding system and machine-readable medium. One method includes receiving by the data processing system a request for a data structure from a calling process, and splitting the data structure into a plurality of substructures by the data processing system. That method includes transferring the plurality of substructures to the calling process by the data processing system, wherein at least two of the substructures are transferred in parallel, and maintaining a transfer state for each substructure in the data processing system.
    Type: Grant

  • Patent number: 8886593
    Abstract: A method for data transfer in a data processing system, and corresponding system and machine-readable medium. One method includes receiving by the data processing system information relating to a data structure to be transferred, where the data structure includes a plurality of elements. Each element in the structure is linked to at least one other element in the structure. The method also includes selecting by the data processing system a group of the plurality of elements, the group including at most a predetermined maximum number of elements. The method further includes transferring by the data processing system the group of elements to a destination. The method also includes assigning by the data processing system the elements of the plurality of elements that are not in the group of elements to one or more substructures. At least one substructure is assigned two or more direct child nodes of transferred nodes.

  • Patent number: 8166208
    Abstract: A system, method, and computer readable medium. A method includes setting a maximum translation delay. The method includes, while a current delay is less than the maximum transfer delay, repeatedly performing the steps of searching for an additional transfer having a same source and target as a current transfer, and when an additional transfer is found, adding the additional transfer to a transfer list that identifies transfers to be made together. The method includes performing a transfer of the transfers identified by the transfer list when the current delay has met or exceeded the maximum transfer delay.

  • Patent number: 5944512
    Abstract: A heating and incineration device includes a heating chamber for being connected to a heating application. A process stream is recirculated between the heating chamber and the heating application. An incineration tube is positioned into the heating chamber for providing the only exit for gases from the heating chamber and the heating application. A heat source is positioned within the heating chamber in spaced coaxial relation with an incineration tube inlet. The process stream is heated to a working temperature when it is passed through the heating chamber around the periphery of the heat source. The heat source is directed at the incineration tube inlet, so that the highest temperature inside the heating chamber is concentrated along an axis between the heat source and the incineration tube inlet. The distance between the incineration tube inlet and the heat source is adjustable for controlling the temperature inside the incineration tube.
