Task scheduling in big and little cores

摘要

One aspect provides a method including: identifying a task to be scheduled for execution on an information handling device having two or more cores of different size; determining an appropriate scheduling of the task for execution on the two or more of cores of different size, wherein the appropriate scheduling of the task is determined via a core signature for the task; directing the task to an appropriate core for execution based on the appropriate scheduling determined; and executing the task on the appropriate core. Other aspects are described and claimed.

1. A method comprising:
identifying a task to be scheduled for execution on an information handling device having two or more cores of different size; determining an appropriate scheduling of the task for execution on the two or more of cores of different size, wherein the appropriate scheduling of the task is determined via a core signature for the task, wherein the core signature is determined via a procedure comprising: determining if the task fits on a little core; determining if the task is high priority; and determining if the task is executable on the little core within a threshold tolerance with respect to little core utilization; directing the task to an appropriate core for execution based on the appropriate scheduling determined; and executing the task on the appropriate core.
