Description
Technical Field
The present invention relates to the field of process creation, and more particularly, to a method and system for determining the number of parallel processes for a running unit.
Background
A process is a running activity of a program in a computer with respect to a data set, and is a basic unit of resource allocation and scheduling by a system, and is also a basis of an operating system structure. The concept of a process has two main points: first, a process is an entity. Each process has its own address space, typically including a text region, a data region, and a stack. The text region stores code executed by the processor, the data region stores variables and dynamically allocated memory used during process execution, and the stack region stores instructions and local variables of active procedure calls. Second, the process is an "executing program". A program is an inanimate entity that can become an active entity only when the processor gives the program life (when it is executed under the control of the operating system).
In the field of process management, more user processes can be run as a result of the user equipment. These processes may compete for the same shared resources. To resolve this contention, it is necessary to queue processes that issue requests for resources and share the resources in turn according to the queuing, i.e., application parallel control is required. Secondly, in order to achieve parallel control within the user equipment, it is necessary that all processes within the user equipment that are involved in achieving a particular function are able to obtain a consistent system state associated with that function,
In practical applications, a user usually needs to perform multiple program or multiple process on the same application, the same software, the same plug-in the user equipment, that is, the same application, the same software, the same plug-in and the like run the same multiple processes. Such program multi-opening is typically to meet the user's customized needs, such as upgrading for a particular role, meeting a particular task requirement, etc.
However, in the prior art, when the same application, the same software, the same plug-in, etc. are subjected to multiple program opening or multiple process opening in the user equipment, the situation that the system runs slowly due to excessive resources occupied by the program or the process usually occurs.

FIG. 1 is a flow chart of a method 100 for determining the number of parallel processes for a runtime unit in accordance with a preferred embodiment of the present invention. The method 100 is capable of reading device description information of the user device, determining hardware information of a processor of the user device based on the device description information, and parsing the hardware information of the processor to determine the number of cores of the processor and a dominant frequency of each core. The method 100 can determine a plurality of running units included in a target application in a plurality of applications in the user equipment in response to running of the target application, and select a running unit needing parallel processes from the plurality of running units according to the parallel requirement of each running unit. When an execution unit requiring parallel processes is running, the method 100 can determine a current utilization rate of each core of the plurality of cores of the processor, and determine a number of parallel processes that can be created for the execution unit requiring parallel processes based on the number of cores, a dominant frequency of each core, and the current utilization rate of each core.
As shown in fig. 1, method 100 begins at step 101. In step 101, device description information of the user equipment is read, and hardware information of a processor of the user equipment is determined based on the device description information. Typically, device description information is generated and stored in the operating system of the user device for distinguishing and identifying hardware in the user device, and so on. Wherein the device description information includes: hardware information of the processor, hardware information of the memory, hardware information of the display device, and hardware information of the interface device. The hardware information of the processor includes: the model number of the processor, the dynamic acceleration frequency, the number of the cores, the main frequency of each core and the cache size. The model of the processor is, for example, the intel corporation's bori 7 920. The dynamic acceleration frequency is, for example, 2.93GHz. The number of cores is, for example, 2 or 4. The primary frequency of each core is, for example, 2.66GHz. The buffer sizes are, for example, a level one buffer 128KB, a level two buffer 1MB, and a level three buffer 8MB.
The hardware information of the memory is, for example, the manufacturer of the memory, the lot number of the product, the storage capacity, and the like. The hardware information of the display device is, for example, the manufacturer, the size, the panel material, etc. of the display device. Hardware information of the interface device such as names of all interfaces included in the user device, etc.
In step 102, the hardware information of the processor is parsed to determine the number of cores of the processor and the dominant frequency of each core. After the hardware information of the processor is obtained, the number of the cores of the processor and the main frequency of each core are determined according to the number of the cores in the hardware information of the processor and the main frequency of each core. The dominant frequency of each core is typically the same and may be referred to as the dominant frequency of the processor.
In step 103, in response to the running of a target application in a plurality of applications in the user equipment, determining a plurality of running units included in the target application, and selecting a running unit needing parallel processes from the plurality of running units according to the parallel requirement of each running unit. The application type of each of the plurality of applications is a game platform application, a browser application, a ticketing application, a gaming application, or a shopping application. When the application type is a browser application, the execution unit may be various plug-ins that execute in the browser. The plug-in may be, for example, a game plug-in, a ticket plug-in, a security plug-in, etc.
Each of the plurality of applications has application description information, and the application description information includes a running unit description table. The execution unit description table comprises a plurality of description items, wherein the format of each description item is < identification of the execution unit, description information of the execution unit and parallel requirement of the execution unit >. Wherein the identification of the execution unit is for example the identification of the plug-in. The description information of the execution unit is for example information describing the function, source, scope of use, etc. of the plug-in, e.g. the function of the game plug-in is shooting aid, from the plug-in developer, the scope of use is a specific design class game. The parallel requirement of the execution unit is, for example, that when a game plug-in having a plurality of functions is executed only to meet one requirement of the user when the shooting game is executed, and when the user needs a plurality of requirements when the shooting game is executed, the game plug-in may need to execute in parallel, that is, there is a parallel requirement. By running multiple identical inserts simultaneously, a user may be enabled to use multiple different shooting aids while playing a shooting game.
And responding to the operation of a target application in a plurality of applications in the user equipment, analyzing an operation unit description table of the target application to determine the number of operation units included in the target application according to the number of description items in the operation unit description table of the target application. For example, if the number of description items is 3, the number of execution units included in the target application is 3. And responding to the running of a target application in a plurality of applications in the user equipment, analyzing a running unit description table of the target application so as to select a running unit needing parallel processes from the plurality of running units according to the parallel requirements of the running units in each description item in the running unit description table of the target application. For example, the parallel requirement of the execution unit may be a boolean expression, e.g., when the value is 1, the parallel requirement of the execution unit is required, and when the value is 0, the parallel requirement of the execution unit is not required.
In step 104, when the running unit of the parallel process is running, determining a current usage rate of each core in the multiple cores of the processor, and determining a number of parallel processes capable of being created for the running unit of the parallel process based on the number of cores, a main frequency of each core and the current usage rate of each core. Wherein determining the current utilization of each of a plurality of cores of the processor comprises: acquiring running state information of the processor; and analyzing the running state information to determine the current utilization rate of each core in the plurality of cores.
Wherein the determining the number of parallel processes that can be created for the execution unit that needs the parallel processes based on the number of cores, the dominant frequency of each core, and the current usage rate of each core includes:
an average current utilization of all cores is determined based on the current utilization of each core. For example, the current usage rates of the four cores are 30%, 25%, and 35%, respectively, and the average current usage rate of all cores is 30%. Where the current utilization is the ratio of the processing resources used by the core or processor to the entire processing resources. The concept opposed to the current usage rate is the current idle rate. The current idle rate is the ratio of unused processing resources of the core or processor to the total processing resources.
When the average current usage is less than a usage threshold, it is determined whether the number of cores is greater than a number threshold and whether the dominant frequency of each core is greater than a dominant frequency threshold. For example, when the usage threshold is 40%, then the average current usage 30% is less than the usage threshold. Wherein the number threshold is for example 2 and the dominant frequency threshold is for example 1.60GHz. When the number of cores is 4 and the dominant frequencies of the four cores are 1.66GHz, then the number of cores is greater than the number threshold and the dominant frequency of each core is greater than the dominant frequency threshold. In this case, the number of parallel processes that can be created is the number of cores (e.g., 4), the number preset by the user (e.g., 20), or the maximum number that can be supported by the processor resources (e.g., 10).
Alternatively, the determining the number of parallel processes that can be created for the execution unit that needs the parallel processes based on the number of cores, the dominant frequency of each core, and the current usage rate of each core includes:
an average current utilization of all cores is determined based on the current utilization of each core. For example, the current usage rates of the four cores are 30%, 25%, and 35%, respectively, and the average current usage rate of all cores is 30%.
When the average current usage is less than a usage threshold, it is determined whether the number of cores is greater than a number threshold and whether the dominant frequency of each core is greater than a dominant frequency threshold. For example, when the usage threshold is 40%, then the average current usage 30% is less than the usage threshold. Wherein the number threshold is for example 2 and the dominant frequency threshold is for example 1.60GHz. When the number of cores is 4 and the main frequency of each of the four cores is 1.50GHz, then
The number of cores is greater than a number threshold and the dominant frequency of each core is less than or equal to the dominant frequency threshold. In this case, the number of parallel processes that can be created is the difference between the number of cores and the number threshold, for example, 4-2=2.
Alternatively, the determining the number of parallel processes that can be created for the execution unit that needs the parallel processes based on the number of cores, the dominant frequency of each core, and the current usage rate of each core includes:
an average current utilization of all cores is determined based on the current utilization of each core. For example, the current usage rates of the four cores are 30%, 25%, and 35%, respectively, and the average current usage rate of all cores is 30%.

For example, when the usage threshold is 40%, then the average current usage 30% is less than the usage threshold. Wherein the number threshold is for example 2 and the dominant frequency threshold is for example 1.60GHz. When the number of cores is 2 and the main frequencies of the four cores are 1.66GHz, the number of cores is smaller than or equal to the number threshold, and the main frequency of each core is greater than the main frequency threshold, the number of parallel processes which can be created is the number threshold, namely 2.
Alternatively, the determining the number of parallel processes that can be created for the execution unit that needs the parallel processes based on the number of cores, the dominant frequency of each core, and the current usage rate of each core includes:
an average current utilization of all cores is determined based on the current utilization of each core. For example, the current usage rates of the four cores are 30%, 25%, and 35%, respectively, and the average current usage rate of all cores is 30%.
When the average current usage is less than a usage threshold, it is determined whether the number of cores is greater than a number threshold and whether the dominant frequency of each core is greater than a dominant frequency threshold. For example, when the usage threshold is 40%, then the average current usage 30% is less than the usage threshold. Wherein the number threshold is for example 2 and the dominant frequency threshold is for example 1.60GHz. When the number of cores is 1 and the main frequencies of the four cores are 1.50GHz, and when the number of cores is less than or equal to the number threshold and the main frequency of each core is less than or equal to the main frequency threshold, the number of parallel processes that can be created is 0, alternatively, the determining the number of parallel processes that can be created for the running unit that needs the parallel processes based on the number of cores, the main frequency of each core, and the current usage rate of each core includes:
An average current utilization of all cores is determined based on the current utilization of each core. For example, the current usage rates of the four cores are 50%, 45%, and 55%, respectively, and the average current usage rate of all cores is 50%.
When the average current usage is greater than or equal to a usage threshold, it is determined whether the number of cores is greater than a number threshold and whether the dominant frequency of each core is greater than a dominant frequency threshold.
