Abstract

A method for dynamic adaptive threading is provided. The method comprises receiving a query request for a recommended number of threads from an application. The method comprises determining the recommended number of threads according to a resource status of a system-on-a-chip (SoC) platform. The method comprises transmitting the recommended number of threads to the application.

First claim

What is claimed is:

1 . A method for dynamic adaptive threading, executed by a processor of an electronic device, the method comprising:
receiving a query request for a recommended number of threads from an application; determining the recommended number of threads according to a resource status of a system-on-a-chip (SoC) platform; and transmitting the recommended number of threads to the application.

2 . The method of dynamic adaptive threading as claimed in claim 1 , further comprising:
receiving a response from the application, wherein the response includes an actual number of threads used by the application; and regularly monitoring the resource status of the SoC platform to determine whether to update the recommended number of threads.

3 . The method of dynamic adaptive threading as claimed in claim 1 , further comprising:
determining whether a runnable thread ratio of the application is greater than a threshold; and transmitting a notification message to notify the application to reduce a demand loading of the application in response to determining that the runnable thread ratio of the application is greater than the threshold.

4 . The method of dynamic adaptive threading as claimed in claim 1 , further comprising:
determining whether a number of idle central processing unit (CPU) cores exceeds a threshold; and transmitting a notification message to notify the application to split an actual number of threads used by the application into a first number of threads; wherein the first number of threads is higher than the actual number of threads.

5 . The method of dynamic adaptive threading as claimed in claim 1 , wherein the resource status of the SoC platform comprises a number of idle CPU cores, a core load state, architectures of CPU cores, or core capabilities.

6 . The method of dynamic adaptive threading as claimed in claim 1 , wherein the query request is received from the application through an Application Programming Interface (API).

7 . A device for dynamic adaptive threading, comprising:
one or more processors; and one or more computer storage media for storing one or more computer-readable instructions, wherein the processor is configured to drive the computer storage media to execute the following tasks: receiving a query request for a recommended number of threads from an application; determining the recommended number of threads according to a resource status of a system-on-a-chip (SoC) platform; and transmitting the recommended number of threads to the application.

8 . The device for dynamic adaptive threading as claimed in claim 7 , wherein the processor further executes the following tasks:
receiving a response from the application, wherein the response includes an actual number of threads used by the application; and regularly monitoring the resource status of the SoC platform to determine whether to update the recommended number of threads.

9 . The device for dynamic adaptive threading as claimed in claim 7 , wherein the processor further executes the following tasks:
determining whether a runnable thread ratio of the application is greater than a threshold; and transmitting a notification message to notify the application to reduce a demand loading of the application in response to determining that the runnable thread ratio of the application is greater than the threshold.

10 . The device for dynamic adaptive threading as claimed in claim 7 , wherein the processor further executes the following tasks:
determining whether a number of idle central processing unit (CPU) cores exceeds a threshold; and transmitting a notification message to notify the application to split an actual number of threads used by the application into a first number of threads; wherein the first number of threads is higher than the actual number of threads.

11 . The device for dynamic adaptive threading as claimed in claim 7 , wherein the resource status of the SoC platform comprises a number of idle CPU cores, a core load state, architectures of CPU cores, or core capabilities.

12 . The device for dynamic adaptive threading as claimed in claim 7 , wherein the query request is received from the application through an Application Programming Interface (API).
