It should be noted that, the method of fig. 1 is a first device-side method, the method of fig. 2 is a second device-side method, and the method of fig. 3 is a method in which the first device-side method and the second device-side method are combined together. The processing method of the computing task is applied to a first device, the first device is connected with at least one second device, the first device can be a master device actively utilizing idle computing resources of the external second device, and the second device can be a slave device connected with the first device and utilizing the idle computing resources.
The first device side method comprises the following steps: step S101, step S102, and step S103; the second device side method comprises: step S201, step S202, and step S203.
The second equipment end method comprises the following steps:
step S201: and the second equipment sends the reported idle computing resources of the second equipment to the first equipment, so that the first equipment determines the idle computing resources of the second equipment according to the reported idle computing resources of the second equipment.
Reporting free computing resources may refer to resources that are currently free for computing, including hardware resources (e.g., processors, memory, etc.), and may also include software resources (e.g., operating systems, etc.), which are not currently available for use when reporting directly.
The first equipment end method comprises the following steps:
step S101: the first device obtains idle computing resources of the second device.
Free computing resources may refer to resources that are unused and that can be used for computing.
When the fluctuation of the reported idle computing resource of the second equipment is small and relatively stable, the idle computing resource of the second equipment can be the reported idle computing resource directly sent by the second equipment; when the reported idle computing resources of the second equipment dynamically fluctuate and are unstable, the idle computing resources of the second equipment can be obtained according to the reported idle computing resources which are sent by the second equipment for many times.

Theoretically, the number of free computing resources of the second device is greater than or equal to the number of computing resources actually needed to complete the first computing task. In general, the second device assists the first device to complete the first computing task is an auxiliary function of the second device, and the second device itself has other functions, and the other functions that complete the second device need computing resources, so in order to avoid that the computing resources actually required for completing the first computing task fully occupy the idle computing resources of the second device and cause that the second device is affected to complete other tasks of the second device, and also in order to make the second device smoother when completing the first computing task, in an embodiment, the number of computing resources actually required for completing the first computing task is smaller than the number of idle computing resources of the second device.

In the embodiment of the application, the external second equipment reports the local reporting idle computing resource; the first equipment determines idle computing resources of the second equipment according to the reported idle computing resources of the second equipment, determines a first computing task of the second equipment according to the idle computing resources of the second equipment, and then sends the first computing task to the second equipment; the second device receives the first computing task and then completes the first computing task using the local free computing resources. Thus, the method of the first equipment side provides technical support for the first equipment to finish the first computing task of the first equipment by using the idle computing resources of the second equipment, and the method of the second equipment side provides technical support for the first equipment to finish the first computing task of the first equipment by using the idle computing resources of the second equipment; when the method of the first equipment end and the method of the second equipment end are combined together, the first equipment can utilize the idle computing resources of the second equipment to finish the first computing task of the first equipment, on one hand, the problem that the chip cost is increased due to the fact that the computing capacity of the first equipment is improved can be avoided, on the other hand, the idle computing resources of the second equipment are utilized to finish the first computing task of the first equipment, the utilization rate of the second equipment can be improved, the waste of the idle computing resources of the second equipment is avoided, on the other hand, the idle computing resources of the second equipment are used as the computing resources of the first equipment, the computing capacity of the first equipment can be indirectly improved, on the other hand, the external second equipment is common general equipment and is not designed for the first equipment alone, and therefore the first equipment can adapt to the external general equipment to improve the computing capacity of the first equipment without additionally increasing the cost of the external equipment.
In an embodiment, step S101 of the method at the first device side, the obtaining the idle computing resource of the second device may include: and acquiring idle computing resources of the second device under the condition that the second device supports resource sharing.
In the embodiment of the present application, supporting resource sharing may refer to supporting other devices to perform computing tasks by using local idle computing resources. In the external devices connected with the first device, some devices do not support resource sharing, some devices support resource sharing, and the method of the embodiment of the application can be implemented only under the condition that the second device supports resource sharing, so that the user requirements corresponding to different external devices can be met.
In an embodiment, before the step S101, the acquiring the idle computing resource of the second device may further include: step S104, step S105, and step S106. Correspondingly, the method at the second equipment side comprises the following steps: step S204, step S205, and step S206.
Step S104: the first device sends first signaling to the second device.
In the embodiment of the application, the role of the first signaling is mainly to inquire whether the second device supports resource sharing.
Step S204: the second device receives the first signaling sent by the first device.
Step S205: the second device sends second signaling to the first device in response to the first signaling.
Step S105: the first device receives second signaling sent by the second device in response to the first signaling, wherein the second signaling is used for indicating whether the second device supports resource sharing.
The second signaling is used for indicating whether the second device supports resource sharing, if the second device supports resource sharing, the second signaling indicates that the second device supports resource sharing, and if the second device does not support resource sharing, the second signaling indicates that the second device does not support resource sharing, and then the method of the embodiment of the application is not implemented.
Step S106: and the first equipment sends a third signaling to the second equipment under the condition that the second equipment supports resource sharing, wherein the third signaling is used for indicating the second equipment to send the reported idle computing resource of the second equipment to the first equipment.
Step S206: and under the condition that the second equipment supports resource sharing, responding to the third signaling, and sending the reported idle computing resource of the second equipment to the first equipment by the second equipment.
In an embodiment, after receiving the third signaling, the second device may trigger a keep-alive message of the second device, where the second device periodically sends, in the form of the keep-alive message, the reported idle computing resource of the second device to the first device. Because the time interval of the sending period of the keep-alive message is shorter, the first device can obtain more idle computing resources reported by the second device, and therefore more accurate idle computing resources of the second device can be obtained.
In the above steps S104, S105, S106, S204, S205, and S206, the interaction process between the first device and the second device may be simply represented by fig. 4: the method comprises the steps that a first device sends a first signaling to a second device, the second device returns a second signaling to the first device after receiving the first signaling, the first device determines that the second device supports resource sharing after receiving the second signaling, and sends a third signaling to the second device, the second device triggers a keep-alive message after receiving the third signaling, periodically sends the keep-alive message to the first device and feeds back reported idle computing resources of the second device, and the first device determines the idle computing resources of the second device according to the reported idle computing resources of the second device, which are periodically sent by the second device.
In an embodiment, step S101 of the method at the first device side, the obtaining the idle computing resource of the second device may include: and acquiring the idle computing resources of the second device under the condition that the idle computing resources of the first device are not enough to complete the total second computing task.
In this embodiment of the present application, the second computing task is a total computing task of the first device, and if the idle computing resources of the first device are enough to complete the second computing task, no external second device is needed to assist in completing the first computing task. Only when the idle computing resources of the first device are insufficient to complete the second computing task, the method of the embodiment of the application is implemented, and the external second device is used to assist in completing the first computing task. In this way, an uncontrolled misuse of the first device by the external second device can be avoided.
In an embodiment, step S101 of the method at the first device side, the obtaining the idle computing resource of the second device may include: and the first equipment determines the idle computing resources of the second equipment according to the reported idle computing resources of the second equipment.

Theoretically, the idle computing resources of the second device may be less than or equal to the average of the plurality of reported idle computing resources. However, when the fluctuation of the reported idle computing resources is large, the idle computing resources of the second device are equal to the average value of the plurality of reported idle computing resources, and the first computing task occupies more idle computing resources of the second device, so that other normal functions, tasks or services of the second device are affected. Thus, in an embodiment, the free computing resources of the second device are smaller than the average of the plurality of reported free computing resources.
In an embodiment, step S101, determining the idle computing resources of the second device according to the plurality of reported idle computing resources periodically sent by the second device may further include: substep S1011, substep S1012, substep S1013, and substep S1014.

Sub-step S1014: and determining the idle computing resource of the second equipment according to the average value and the influence factor, wherein the idle computing resource of the second equipment is equal to the product of the average value and the influence factor, and the influence factor is smaller than 1.
The above-mentioned substep S1011 to substep S1014 are specifically described as follows:
the second device periodically sends the current reported idle computing resources to the first device. Then, the first device takes the current time t now Until t now Reporting of idle computing resources M sent during the period of time t 1 ,M 2 ,...,M t The mean μ and variance σ of these values are calculated 2 Obtaining a normal distribution probability density function:

The method is suitable for computing the idle computing resources of all second devices externally connected with the first device.
In an embodiment, step S102, the determining, according to the idle computing resource of the second device, the first computing task of the second device may include: substep S102A1, substep S102A2, substep S102A3 and substep S102A4.
Substep S102A1: and determining the total second computing task of the first device, computing resources required by the second computing task and idle computing resources of the first device.
Substep S102A2: and determining a third computing task which can be completed by the idle computing resource of the first device when the idle computing resource of the first device is smaller than the computing resource required by the second computing task.
Substep S102A3: and determining the computing resources required by the residual computing task, wherein the residual computing task is the remaining computing task after the second computing task minus the third computing task.
