Background

A CPU (Central Processing Unit) may include multiple physical cores, where each physical core may be divided into multiple logical cores. The application process of the application is bound with the logic core of the CPU, so that the application process can be prevented from being switched among different logic cores included in the CPU, and the performance of the application process can be effectively improved.

However, for some applications, during the execution of the application, a sub-process of the application process may be generated to perform other tasks. At this time, the application process is the parent process corresponding to the child process. The parent process and the child process share the resource, that is, the parent process is bound to the logical core, and therefore the child process is also bound to the logical core. Therefore, in the process of running the parent process and the child process, resource competition conflict can be generated between the parent process and the child process, and the performance of the parent process and the child process is affected. Based on this, it is desirable to provide a method for binding an application process and a processor core, so as to improve the performance of the parent process and the child process in the above scenario.

Before explaining the embodiments of the present application in detail, an application scenario related to the embodiments of the present application will be described.

At present, the performance of an application process can be improved by binding the application process of an application with a logic core of a CPU, however, in the running process of some applications, a sub-process of the application process may be generated to execute other tasks, and since the sub-process and the application process share resources, the sub-process and the application process are bound in the same logic core, so that resource competition may be generated between the sub-process and the application process, and the performance of the application process is reduced on the contrary. The method for binding the application process and the processor core provided by the embodiment of the application process and the processor core can be used for adjusting the binding relationship between the application process and the logic core according to the process state change of the target application in the above scenario, so that resource competition between the application process and the sub-process is avoided.

For example, for a single-process Redis database, an application process of the Redis database may be bound to one logical core in the CPU, so that the performance of the application process may be greatly improved. However, when the Redis is configured with the persistence process, a sub-process is generated during the persistence process, and thus the sub-process and the application process of the Redis are bound to the same logical core, which causes resource competition between the sub-process and the application process of the Redis. Under such a condition, the application process and processor core binding method provided by the embodiment of the application can be adopted to unbind the application process and the logic core of the Redis; when the fact that the sub-process exits is detected, the application process of the Redis is bound with the logic core again, so that the performance of the application process of the Redis is improved, and meanwhile resource competition between the application process of the Redis and the sub-process is avoided.

Next, a system architecture related to the method for binding an application process and a processor core provided in the embodiment of the present application is described.

Fig. 1 is a system structure diagram of a terminal according to a method for binding an application process and a processor core provided in an embodiment of the present application. As shown in fig. 1, the terminal 100 includes a processor 101, an application 102, and a memory 103. Processor 101 includes a plurality of physical cores, each of which includes a plurality of logical cores. Processor 101 may communicate with applications 102, memory 103.

Wherein the processor 101 may bind the application process of the application 102 on the logical core. Then, the processor 101 may detect a process state change of the application 102 according to the application identifier of the application 102, and when a process state change result is used to indicate a sub-process corresponding to the application process of the newly added application 102, the processor 101 may unbundle the application process of the application 102 from the logical core. When the process state change result is used to indicate that the sub-process corresponding to the application process of the application 102 exits, the processor 101 may bind the application process of the application 102 with the logical core.

The application 102 is a single-process application installed on the terminal 100, and an application process of the application 102 may be bound to a logical core of the processor, so that the application process is always processed on the logical core and is not switched between multiple logical cores of the processor. During operation of the application 102, sub-processes of the application process may be spawned to perform other tasks. At this time, the application process of the application 102 is the parent process corresponding to the child process.

The memory 103 is used for storing programs of application processes of the application 102, data generated during execution of the application processes, and the like.

Next, a method for binding an application process and a processor core provided in the embodiment of the present application is introduced.

Fig. 2 is a flowchart of a method for binding an application process and a processor core according to an embodiment of the present disclosure, where the method may be applied to a processor, which may be referred to as the processor 101 in fig. 1. As shown in fig. 2, the method comprises the steps of:

step 201: the application process of the target application is bound with a target logic core of a CPU of the processor, and the target logic core is any one of a plurality of logic cores of the CPU.

The CPU may include a plurality of physical cores, each of the plurality of physical cores may include a plurality of logical cores, and the application process of the target application may be bound to one logical core of the CPU. The target application is a single-process application, that is, the target application only generates one main process when being executed.

As an example, the processor of the terminal may control the display device to display a configuration page, where the configuration page includes at least an affinity configuration item, and the affinity configuration item is used to indicate a logical core to which an application process of the target application is to be bound. The user may input a logical core identifier in the affinity configuration item, and the processor may obtain the logical core identifier input by the user, and use the logical core identified by the logical core identifier as the target logical core. Thereafter, when the target application is detected to be launched, the processor may bind the application process of the target application with the target logical core.

Optionally, the target logic core may be one logic core selected according to processing capabilities of the plurality of logic cores, or may be one logic core arbitrarily selected from the plurality of logic cores, which is not limited herein in this embodiment of the application.

After the processor binds the application process of the target application with the target logic core, the application process of the target application is only processed on the target logic core, so that the application process of the target application can be prevented from being switched among a plurality of logic cores. When the application processes are processed on different logic cores, execution environments need to be built, for example: the register, the display card and the like, so that after the application process of the target application is bound with the target logic core, the execution environment switching expense caused by repeated switching of the application process among a plurality of logic cores is reduced. And the application process of the target application is bound with the target logic core, so that the probability of acquiring the required program from the cache memory can be improved.

Step 202: and detecting the process state change of the target application according to the identification of the target application.

After the target application is started and the application process of the target application is bound with the target logic core, the processor may determine the process state of the target application according to the identifier of the target application at preset time intervals, and determine the state change result of the application process of the target application according to the process state of the target application at the current time and the process state determined most recently before the current time.

The preset time interval is a time interval stored in the processor, and may be 1s, for example. In addition, the state change result is used for indicating that the sub-process corresponding to the application process of the newly added target application or the sub-process corresponding to the application process of the target application exits.

It should be noted that, during the running process of the target application, a sub-process corresponding to the application process of the target application may be newly added, and other tasks are executed by the sub-process, and when the sub-process executes other tasks, the sub-process exits.

For example, Redis is a single-process memory database, when Redis performs persistence, that is, when data backup is performed, Redis adds a new sub-process corresponding to a Redis application process, and performs data backup through the sub-process, and after the data backup is completed, the sub-process exits.

In some embodiments, the processor may determine, at preset time intervals, a process state of the target application according to the identifier of the target application; and if the process state determined at the current moment is the first state and the process state determined last time before the current moment is the second state, determining that the state change result of the application process of the target application is the first state change result. The first state indicates that the target application corresponds to a plurality of processes with the same process name, the process identifier of one process in the plurality of processes is the same as the parent process identifier of the other process, the second state indicates that the target application corresponds to one application process, and the first state change result is used for indicating a child process corresponding to the application process added with the target application.

It should be noted that each process may include a process name, a process identifier, and an application identifier. Optionally, when the process is a child process, a parent process identifier may be further included, where the parent process identifier is the same as the process identifier of the parent process corresponding to the process, and the process names of the parent process and the child process are the same.

As an example, the processor may obtain all current processes of the terminal, and then, according to the application identifier of the target application, find a process that includes the application identifier that is the same as the application identifier of the target application from all the processes. And determining the process state of the target application at the current moment according to the searched process, and correspondingly storing the process state of the target application at the current moment and the current moment.

Specifically, when the process corresponding to the target application is found to include multiple processes with the same process name, and a parent process identifier included in at least one process is the same as a process identifier of an application process of the target application, at this time, it may be determined that the process of the target application exists in a child process, that is, it may be determined that the process state of the target application at the current time is the first state. When the process corresponding to the searched target application does not include multiple processes with the same name, it may be determined that the process of the target application does not have a sub-process, that is, it may be determined that the process state of the target application at the current time is the second state. Then, the terminal may store the correspondence between the process state at the current time and the current time.

For example, it is assumed that the processor determines that the process corresponding to the target application is as shown in table 1 below, where the process corresponding to the application identified by the application 1 includes two processes with the same process name, and the process with the process identifier 2 corresponds to the parent process identifier 1, and the parent process identifier is the same as the process identifier of the process with the process identifier 1, that is, the process with the process identifier 2 is a child process of the process with the process identifier 1, and at this time, it may be determined that the process state of the application identified by the application 1 at the current time is the first state.

TABLE 1

Process name	Process identification	Parent process identification	Application identification
				Process 1	1	Applications 1
Process 1	2	1	Applications 1

For another example, the processor determines that the process corresponding to the target application is as shown in table 2 below, where the process corresponding to the application identified by the application 1 does not include two processes with the same process name, but only includes one process, and at this time, the process state of the application identified by the application 1 at the current time may be determined to be the second state.

TABLE 2

Process name	Process identification	Application identification
			Process 1	1	Applications 1

After the processor determines the process state of the target application at the current time, the process state determined last time before the current time can be obtained from the stored corresponding relation, and the state change result of the application process of the target application is determined according to the process state at the current time and the process state determined last time before the current time.

The process state determined at the current time is a first state, which indicates that the process of the target application includes the sub-process, while the process state determined last time before the current time is a second state, which indicates that the process of the target application determined last time before the current time does not include the sub-process. In this way, the sub-process corresponding to the application process to which the target application is newly added may be determined, that is, the state change result of the application process of the target application may be determined to be the first state change result.

Illustratively, assume that the processor determines the process state every 1s, and the stored partial correspondence is as shown in table 3. After determining that the process state at the current time 12:00 is the first state, the processor may acquire the process state determined last time before the current time from the stored correspondence, that is, the process state corresponding to 11:59 is the second state, and thus, it may be determined that the state change result of the application process of the target application is the first state change result.

TABLE 3

The current time	Process state
		11:58	Second state
11:59	Second state

In other embodiments, if the process state determined at the current time is the second state and the process state determined last time before the current time is the first state, the state change result of the application process of the target application is determined to be the second state change result, and the second state change result is used to indicate that the sub-process corresponding to the application process of the target application exits.

In this case, the process state determined at the present time is the second state indicating that the process of the target application does not include the child process, and the process state determined last before the present time is the first state indicating that the process of the target application determined last before the present time includes the child process. In this way, it may be determined that the sub-process corresponding to the application process of the target application exits, that is, it may be determined that the state change result of the application process of the target application is the second state change result.

Illustratively, assume that the processor determines the process state every 1s, and the stored partial correspondence is as shown in table 4. After determining that the process state at the current time 12:26 is the second state, the processor may acquire the process state determined last time before the current time from the stored correspondence, that is, the process state corresponding to 12:25 is the first state, and thus, may determine that the state change result of the application process of the target application is the second state change result.

TABLE 4

Current time of day	Process state
		12:25	First state
12:26	Second state

Step 203: and adjusting the binding relationship between the application process of the target application and the target logic core according to the detected state change result.

In some embodiments, when the state change result detected by the processor is the first state change result, the application process of the target application is unbound from the target logical core.

And when the state change result detected by the processor is the first state change result, indicating that a child process corresponding to the application process of the target application is newly added, wherein the application process of the target application is a parent process corresponding to the child process. In this case, the parent process and the child process may share resources, i.e., since the parent process is bound to the target logical core, the child process is also bound to the target logical core. Therefore, in the running process of the parent process and the child process, resource competition conflict can be generated between the parent process and the child process, and the performance of the parent process and the performance of the child process are affected. To avoid this, when the processor determines that the state change result is the first state change result, the application process of the target application may be unbound from the target logical core.

After the processor unbinds the application process of the target application and the target logic core, the processor may allocate a first logic core to the application process of the target application, allocate a second logic core to a sub-process corresponding to the application process of the target application, and the first logic core and the second logic core are two different logic cores of a plurality of logic cores included in the CPU.

It should be noted that, when the processor allocates the first logic core to the application process of the target application and allocates the second logic core to the sub-process corresponding to the application process of the target application, the first logic core and the second logic core may be selected according to the processing capabilities of the plurality of logic cores, or the first logic core and the second logic core may be arbitrarily selected from the plurality of logic cores, which is not limited herein in this embodiment of the application.

In other embodiments, when the state change result detected by the processor is the second state change result, the application process of the target application and the target logical core are bound again.

And when the state change result detected by the processor is a second state result, indicating that the sub-process corresponding to the application process of the target application exits. In this case, since the child process has already exited, there is no problem that resource contention conflict is generated between the parent process and the child process, and therefore, the application process of the target application and the target logical core can be bound again, so as to improve the performance of the application process of the target application.

In this embodiment, a process state change of the target application may be detected, where the detected process state change result may include a sub-process corresponding to an application process of the newly added target application or a sub-process exit corresponding to an application process of the target application. Therefore, when the terminal determines the sub-process corresponding to the application process of the newly added target application according to the process state change result, the binding between the application process of the target application and the target logic core can be released. When the terminal determines that the sub-process of the target application exits according to the process state change result, the application process of the target application and the target logic core can be bound again, so that resource competition conflict between the application process of the target application and the sub-process is avoided.

if the process state determined at the current moment is the first state and the process state determined last time before the current moment is the second state, determining that the state change result of the application process of the target application is the first state change result;

the first state indicates that the target application corresponds to a plurality of processes with the same process name, the process identifier of one process in the plurality of processes is the same as the parent process identifier of the other processes, the second state indicates that the target application corresponds to one application process, and the first state change result is used for indicating the child process corresponding to the application process with the new target application.

Optionally, the detection module 302 is further specifically configured to:

and if the process state determined at the current moment is the second state and the process state determined last time before the current moment is the first state, determining that the state change result of the application process of the target application is the second state change result, wherein the second state change result is used for indicating that the sub-process corresponding to the application process of the target application exits.

Optionally, the adjusting module 303 is specifically configured to:

and when the detected state change result is a second state change result, the application process of the target application and the target logic core are bound again.

In summary, in the embodiment of the present application, a process state change of the target application may be detected, where a detected process state change result may include a sub-process corresponding to an application process of the newly added target application or a sub-process exit corresponding to an application process of the target application. Therefore, when the terminal determines the sub-process corresponding to the application process of the newly added target application according to the process state change result, the binding between the application process of the target application and the target logic core can be released. When the terminal determines that the sub-process of the target application exits according to the process state change result, the application process of the target application and the target logic core can be bound again, so that resource competition conflict between the application process of the target application and the sub-process is avoided.
