Abstract

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.
