Summary:Task scheduling in a computing device may be based in part on voltage regulator efficiency. For an additional task to be scheduled, multiple task scheduling cases may be determined that represent execution of the additional task on each of a number of processors concurrently with one or more other tasks executing among the processors. For each task scheduling case, a regulator input power level for a voltage regulator may be determined based on a performance level indication associated with the additional task, the one or more other tasks executing on the processors, and the efficiency level of each voltage regulator. For each task scheduling case, a total regulator input power level may be determined by summing the regulator input power levels for all voltage regulators. The additional task may be executed on a processor associated with a task scheduling case for which total regulator input power is lowest.
