  • Patent number: 8180997
    Abstract: A method, system and computer program product for dynamically composing processor cores to form logical processors. Processor cores are composable in that the processor cores are dynamically allocated to form a logical processor to handle a change in the operating status. Once a change in the operating status is detected, a mechanism may be triggered to recompose one or more processor cores into a logical processor to handle the change in the operating status. An analysis may be performed as to how one or more processor cores should be recomposed to handle the change in the operating status. After the analysis, the one or more processor cores are recomposed into the logical processor to handle the change in the operating status. By dynamically allocating the processor cores to handle the change in the operating status, performance and power efficiency is improved.

  • Patent number: 8055881
    Abstract: A computation node according to various embodiments of the invention includes at least one input port capable of being coupled to at least one first other 5 computation node, a first store coupled to the input port(s) to store input data, a second store to receive and store instructions, an instruction wakeup unit to match the input data to the instructions, at least one execution unit to execute the instructions, using the input data to produce output data, and at least one output port capable of being coupled to at least one second other computation node. The node may also include a router to direct the output data from the output port(s) to the second other node. A system according to various embodiments of the invention includes and external instruction sequencer to fetch a group of instructions, and one or more interconnected, preselected computational nodes.
