Abstract
In one embodiment, a node comprises a plurality of processor cores and a node controller configured to receive a first read operation addressing a first register. The node controller is configured to return a first value in response to the first read operation, dependent on which processor core transmitted the first read operation. In another embodiment, the node comprises the processor cores and the node controller. The node controller comprises a queue shared by the processor cores. The processor cores are configured to transmit communications at a maximum rate of one every N clock cycles, where N is an integer equal to a number of the processor cores. In still another embodiment, a node comprises the processor cores and a plurality of fuses shared by the processor cores. In some embodiments, the node components are integrated onto a single integrated circuit chip (e.g. a chip multiprocessor).
