Abstract

Among other things, one or more techniques and/or systems are provided for controlling resource access for background tasks. For example, a background task created by an application may utilize a resource (e.g., CPU cycles, bandwidth usage, etc.) by consuming resource allotment units from an application resource pool. Once the application resource pool is exhausted, the background task is generally restricted from utilizing the resource. However, the background task may also utilize global resource allotment units from a global resource pool shared by a plurality of applications to access the resource. Once the global resource pool is exhausted, unless the background task is a guaranteed background task which can consume resources regardless of resource allotment states of resource pools, the background task may be restricted from utilizing the resource until global resource allotment units within the global resource pool and/or resource allotment units within the application resource pool are replenished.

Claims

1. A computing system comprising:

one or more processors;

one or more hardware storage device having stored computer-executable instructions which are executable by the one or more processors for causing the computing system to;

initialize an application resource pool for an application with a predetermined quantity of available consumable resource units associated with a resource available to the computing system for consumption by the application;

determine that the application resource pool is exhausted in response to determining that all of the available consumable resource units associated with the application resource pool are consumed and that that are no available consumable resource units remaining in the application resource pool; and

restrict the application from utilizing the resource in response to determining that the application resource pool is exhausted.

2. The computing system of claim 1, wherein the computer-executable instructions are further executable by the one or more processors for causing the computing system to:

detect a replenishment event for triggering a replenishment of one or more new consumable resource units to the application resource pool; and

replenish the application resource pool by allocating the one or more new available consumable resource units to the application resource pool in response to the replenishment event.

3. The computing system of claim 2, wherein the replenishing event occurs subsequent to the application resource pool becoming exhausted.

4. The computing system of claim 3, wherein the computer-executable instructions are further executable by the one or more processors for causing the computing system to remove restrictions placed on access to the resource by the application when the one or more new available consumable resource units become available in the application resource pool.

5. The computing system of claim 2, wherein a predetermined replenishment quantity of the one or more new consumable resource units that are replenished to the application resource pool is based on a device state of the computing system.

6. The computing system of claim 5, wherein the computer-executable instructions are further executable by the one or more processors for causing the computing system to:

detect a change in the device state; and

modify the predetermined replenishment quantity in response to the detected change in the device state.

7. The computing system of claim 6, wherein the device state is a power state.

8. The computing system of claim 2, wherein a predetermined replenishment quantity of the one or more new consumable resource units that are replenished to the application resource pool is based on a type of the application, such that an association of a different type of the application to the application resource pool will cause a correspondingly different predetermined replenishment quantity to be associated with the application resource pool.

9. The computing system of claim 1, wherein the replenishing event comprising a tolling of a predetermined period of time.

10. The computing system of claim 1, wherein the replenishing event comprises a change in a device state of the computing system.

11. The computing system of claim 10, wherein the change in the device state comprises a change in a power state.

12. The computing system of claim 1, wherein the predetermined quantity of available consumable resource units corresponds to an initial maximum size value of the application resource pool and wherein the computer-executable instructions are further executable by the one or more processors for causing the computing system to:

detect a change in the device state; and

resize the initial maximum size value of the application resource pool in response to the detected change in the device state.

13. The computing system of claim 12, wherein the initial maximum size value associated with the application resource pool is based on the device state of the computing system, such that a different device state of the computing system causes the application resource pool to have a correspondingly different initial maximum size value.

14. The computing system of claim 13, wherein the device state is a power state.

15. The computing system of claim 12, wherein the initial maximum size value associated with the application resource pool is based on an application type, such that an association of a different application to the application resource pool causes a correspondingly different initial maximum size value to be associated with the application resource pool.

16. The computing system of claim 12, wherein the resizing includes reducing the maximum size value associated with the application resource pool and a corresponding amount of available consumable resource units in the application resource pool.

17. The computing system of claim 9, wherein the resizing includes increasing the initial maximum size value associated with the application resource pool and a corresponding amount of available consumable resource units in the application resource pool.

18. The computing system of claim 1, wherein the computer-executable instructions are further executable by the one or more processors for causing the computing system to:

initiate a transfer of a predetermined quantity of other consumable resource units to the application resource pool from a global resource pool that is associated with a predetermined maximum quantity of the other consumable resource units in response to detecting the application resource pool is exhausted.

19. One or more hardware storage device having stored computer-executable instructions which are executable by one or more processors of a computing system to cause the computing system to:

initialize an application resource pool for an application, the application resource pool having a predetermined quantity of available consumable resource units associated with a resource for consumption by the application, wherein consumption of all the available consumable resource units by the application causes an exhaustion of the application resource pool;

determine that the application resource pool is exhausted in response to all of the available consumable resource units associated with the application resource pool being consumed and that that are no available consumable resource units remaining in the application resource pool; and

restrict the application from utilizing the resource in response to determining that the application resource pool is exhausted.

20. A method implemented by a computing system for controlling resource access for background tasks, comprising:

initializing an application resource pool for an application, the application resource pool having a predetermined quantity of available consumable resource units associated with a resource for consumption by the application, wherein consumption of all the available consumable resource units by the application causes an exhaustion of the application resource pool;

determining that the application resource pool is exhausted in response to all of the available consumable resource units associated with the application resource pool being consumed and that that are no available consumable resource units remaining in the application resource pool; and

restricting the application from utilizing the resource in response to determining that the application resource pool is exhausted.
