1. A method comprising: identifying a task to be scheduled for execution on an information handling device having a big core and a little core, wherein the little core is a lower power central processing unit with respect to the big core; scheduling the task for execution on the little core using a core signature for the task, wherein the core signature identifies the task as a task to be executed on the little core and is assigned before execution of the task on the information handling device and wherein the core signature is based upon determining if the task is executable on the little core within a threshold tolerance with respect to little core utilization; directing the task to the little core for execution based on the scheduling; entering the big core into a reduced power mode; and executing and completing the task on the little core.
