Abstract: Provided is a method for scheduling of tasks for an operating system on a multi-core processor. The method includes receiving a system call for initiating a scheduling operation on a second core and invoking a scheduling instance to the second core, and the scheduling instance notifies the scheduling operation of an incoming high priority task. Further, the method includes deferring a switching context instance at the second core, and the deferring the switching context instance at the second core includes unblocking the first core to perform other tasks.
