Centralized task scheduling

A non-transitory machine-readable medium having executable instructions to cause one or more processing units to perform a method to schedule a background task for a device, the method comprising:

• determining a time-dependent task importance for the background task, where the time-dependent task importance is based on a time that has elapsed since the background task is initially available to run;
• determining an available device headroom to run the background task;
• and
• if the time-dependent task importance is less than the available device headroom, launching the background task.

A method to schedule a background task for a device, the method comprising:

• registering the background task, wherein the registering includes,
• storing an execution criteria for the background task, the execution criteria indicates one or more criteria for launching the background task and the execution criteria based on a component status of the device;
• monitoring a running state of the device for an occurrence of the execution criteria;
• if the execution criteria occurs,
• determining an available device headroom to run the background task, and
• launching the background task if the available device headroom is greater than a background task importance and the background task importance is a measure of how important it is for the device to run the background task.

A device to schedule a background task for a device, the device comprising:

• a processor;
• a memory coupled to the processor though a bus;
• and
• a process executed from the memory by the processor to cause the processor to register a background task, monitor a running state of the device for an occurrence of the execution criteria, if the execution criteria occurs, determine an available device headroom to run the background task, and launch the background task if the available device headroom is greater than a background task importance and the background task importance is a measure of how important it is for the device to run the background task, wherein for the registering the process further causes the processor to store an execution criteria for the background task, the execution criteria indicates one or more criteria for launching the background task and the execution criteria based on a component status of the device.
