    Abstract: A method and apparatus includes a multi-processor apparatus including a plurality of integrated circuit processors having a shared thermal platform. Each processor has at least one subsystem operable at a plurality of different power settings, at least one internal thermal parameter detector providing power data related to the processor, and a power management unit. The method and apparatus illustratively shares power data from the at least one internal thermal parameter detector of each processor between the power management units of the plurality of processors; compares the shared power data from the plurality of processors to a thermal design power limit for the shared thermal platform; and controls a power setting of the at least one subsystem of the plurality of processors within the shared thermal platform based on the comparison of the shared power data to the thermal design power limit for the shared thermal platform.

    Abstract: Power management for a processing system that has multiple processing units, (e.g., multiple graphics processing units (GPUs), is described herein. The processing system includes a power manager that obtains performance, power, operational or environmental data from a power management unit associated with each processor (e.g., GPU). The power manager determines, for example, an average value with respect to at least one of the performance, power, operational or environmental data. If the average value is below a predetermined threshold for a predetermined amount of time, then the power manager notifies a configuration manager to alter the number of active processors (e.g., GPUs), if possible. The power may then be distributed among the remaining GPUs or other processors, if beneficial for the operating and environmental conditions.
