Integrated link calibration and multi-processor topology discovery

摘要

Integrating link calibration and dynamic topology discovery in a multi-processor system establishes a first of a plurality of processors in the multi-processor system as a director of integrated link calibration and dynamic topology discovery. A plurality of high speed interconnects connects the plurality of processors with each other. The director processor directs calibration of each of the plurality of high speed interconnects via a shared hardware resource. The shared hardware resource is shared among the plurality of processors. Topology of the multi-processor system is incrementally discovered as each of the plurality of high speed interconnects is calibrated based on a result of each of the plurality of high speed interconnects being calibrated.

1. A method comprising:
establishing a first of a plurality of processors in a multi-processor system as a director of integrated interconnect calibration and dynamic topology discovery, wherein a plurality of high speed interconnects connects the plurality of processors with each other; calibrating each of the plurality of high speed interconnects as directed by the director via a shared hardware resource, wherein the shared hardware resource is shared among the plurality of processors; and incrementally discovering topology of the multi-processor system as each of the plurality of high speed interconnects is calibrated and based, at least in part, on results of the plurality of high speed interconnects being calibrated.
