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.
