Description

Technical Field

[0001] The present invention relates to the field of computer technology, and more specifically to a dynamic configuration system, device and readable storage medium of a simulation environment. Background Art

[0002] Hyper-threading technology is a hardware technology that can make a single physical CPU core look like multiple independent processors, allowing a single physical core to process multiple threads simultaneously, thereby improving the overall efficiency of the processor. Hyper-threading technology is particularly applicable in scenarios that require parallel processing, such as multitasking, server virtualization, big data processing, and high-performance computing. It can significantly improve the CPU resource utilization of the processor when processing multiple tasks simultaneously by reducing resource idle time.

[0003] Currently, for a server environment with multiple users in parallel, users have different performance requirements for running programs, and the server load varies at different times. If there are many simulation users, a single physical core can support more simulation environments through multi-threaded parallelism after hyperthreading is enabled. For a situation with fewer simulation users or higher simulation performance requirements, multi-threaded parallelism of physical cores after hyperthreading is enabled may cause resource contention, so hyperthreading needs to be turned off to avoid affecting the task processing efficiency of the CPU single thread.

[0004] However, currently the server manages the opening or closing of hyperthreading based on the entire CPU. It does not support dynamic switching of the hyperthreading state when the simulation system is running, nor does it support separate configuration of the physical cores bound to the simulation environment. Summary of the invention

[0005] In response to the above problems, the purpose of the present invention is to provide a dynamic configuration system, device and readable storage medium for a simulation environment, which can select simulation environments of different modes according to simulation performance requirements and server load conditions, and achieve more optimized configuration of CPU resources by dynamically configuring the hyper-threading state of the CPU core.

[0058] 1. After receiving the simulation environment application, the present invention can adjust the hyperthreading of the CPU core according to different modes. During the adjustment process, it is necessary to interact with the resource management pool to obtain the current hyperthreading state of the CPU core and the core binding state of the existing simulation environment, and allocate the simulation environment after the configuration is completed; at the same time, after receiving the user's simulation environment release request, it can obtain the hyperthreading configuration of the simulation environment binding core from the resource management pool and restore it to the initial state through the configuration restoration module, and then release the simulation environment. In addition, the present invention can also regularly check whether the status of the CPU core and the simulation environment resource pool is normal, and promptly discover and correct the abnormal CPU hyperthreading state and the error storage information of the simulation environment.

[0059] 2 The present invention achieves the effect of turning on or off hyperthreading by turning on or off a logical core corresponding to a physical core. This configuration method can realize the dynamic allocation of CPU resources by the simulation process.

[0074] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0075] See also Figure 1 As shown, this embodiment provides a dynamic configuration system for a simulation environment, which runs in a server and specifically includes: a basic configuration unit 1, a user simulation environment application processing unit 2, a simulation environment release processing unit 3, a resource management pool 4 and a resource management pool maintenance unit 5.

[0076] The basic configuration unit 1 is used to initialize the CPU core configuration of the server, configure the resource management pool, set the core allocation principle of the simulation environment, and set the hyperthreading switch mode of a single physical core.

[0077] In a specific implementation, the basic configuration unit 1 is specifically used to perform basic configuration of the system, and the configuration content is as follows:

[0078] 1. CPU core initialization configuration:

[0079] (1) Enable Hyper-Threading through BIOS and put the processor in Hyper-Threading state.

[0080] (2) Set all logical cores to online.

[0081] 2. Resource management pool configuration:

[0082] (1) Based on the CPU cores of the current server, the number and number of available logical cores in the simulation environment are allocated and these logical cores are isolated.

[0083] (2) Determine the mapping relationship between logical cores and physical cores, where each physical core is mapped to two logical cores.

[0084] (3) Writing the hyperthreading status information of the available CPU cores in the simulation environment and the current simulation environment information into the resource management pool; the simulation environment information includes the process number of the existing simulation environment process, the simulation environment mode, the bound logical core number, etc.

[0085] 3. Set the core allocation principle of the simulation environment:

[0086] (1) Each simulation environment is independently bound to a logical core and is not shared with other simulation environments;

[0087] (2) Bind idle logical cores when allocating simulation environment processes.

[0088] 4. Hyperthreading on / off configuration for a single physical core:

[0089] Currently, turning on or off the hyperthreading state through BIOS requires restarting the server, which will cause the simulation task in progress to be interrupted, data to be lost or damaged, and may also cause unnecessary wear and tear on the hardware, affecting the stability and availability of the system. In order to ensure the continuity of the simulation environment and the integrity of the data, frequent power on and off operations should be avoided as much as possible. Therefore, this system chooses to turn off hyperthreading at the software layer (inside the OS), that is, turn off (offline) a logical core corresponding to each physical core, and retain one logical core corresponding to one physical core to achieve the effect of turning off hyperthreading.

[0090] It should be noted that the operating system kernel controls the enable or disable status of a specific CPU core by writing 1 or 0 to the / sys / devices / system / cpu / cpuX / online file. The hyperthreading on / off mentioned later refers to the enable or disable of a single physical core of the CPU configured by the operating system.

[0091] The user simulation environment application processing unit 2 is used to receive the simulation environment application sent by the user, adjust the hyperthreading of the CPU core using the resource management pool according to the simulation environment mode selected by the user, and allocate the simulation environment.

[0092] Among them, users can choose the simulation environment mode when applying for the simulation environment. The simulation environment mode includes functional mode and performance mode. The functional mode only requires the correctness, stability and integrity of the simulation function; while the performance mode expects the system to allocate more CPU computing resources and has higher requirements for the performance of the simulation environment.

[0093] In a specific implementation, the user simulation environment application processing unit 2 includes: a first interaction interface 21 , a mode configuration module 22 and a simulation environment allocation module 23 .

[0094] The first interactive interface 21 is used to receive a simulation environment application sent by a user.

[0095] The mode configuration module 22 is used to determine the physical cores for executing the simulation environment by executing the physical core configuration mechanism according to the simulation environment mode selected by the user.

[0096] The simulation environment allocation module 23 is used to allocate physical cores to the simulation environment and update the hyperthreading state information of the available CPU cores of the simulation environment in the resource management pool and the current simulation environment information.

[0097] The resource management pool 4 is used to store the hyperthreading status information of the available CPU cores in the simulation environment and the current simulation environment information; the simulation environment information includes the process number of the simulation environment process, the simulation environment mode, and the bound logical core number.

[0098] It should be noted that the CPU core or simulation environment information involved in the hyperthreading adjustment or recovery process is all called from the resource management pool 4, and the resource management pool 4 can be implemented through a database or other algorithms.

[0099] The simulation environment release processing unit 3 is used to receive a simulation environment release request sent by a user, obtain the simulation environment information of the simulation environment from the resource management pool, restore the bound logical core to the initial state according to the simulation environment information, and release the simulation environment.

[0100] In a specific implementation, the simulation environment release processing unit 3 includes: a second interaction interface 31 , a configuration restoration module 32 and a simulation environment release module 33 .

[0101] The second interactive interface 31 is used to receive a simulation environment release request sent by a user.

[0102] The configuration restoration module 32 is used to determine the physical core bound to the simulation environment by executing the hyperthreading state recovery mechanism according to the simulation environment release request, and restore its hyperthreading state.

[0103] The simulation environment releasing module 33 is used to release the simulation environment and update the hyperthreading state information of the available CPU cores in the simulation environment in the resource management pool and the current simulation environment information.

[0104] The resource management pool maintenance unit 5 is used to regularly check the usage of the available logical cores of each simulation environment and the simulation environment information of the resource management pool, so as to identify the simulation environment process that abnormally exits the performance mode and perform correction processing.

[0105] The present invention discloses a dynamic configuration system for a simulation environment. When the system is running, after the user simulation environment application processing unit 2 receives the simulation environment application through the first interactive interface 21, the mode configuration module 22 adjusts the hyperthreading of the CPU core according to different modes. During the adjustment process, it is necessary to interact with the resource management pool 4 to obtain the current hyperthreading state of the CPU core and the core binding state of the existing simulation environment, and use the simulation environment allocation module 23 to perform corresponding configuration. After the configuration is completed, the simulation environment is allocated. After the second interactive interface 31 of the simulation environment release processing unit 3 receives the user simulation environment release request, it obtains the hyperthreading configuration of the core bound to the simulation environment from the resource management pool 4 and restores it to the initial state through the configuration restoration module 32, and then uses the simulation environment release module 33 to release the simulation environment. The main function of the resource management pool maintenance unit 5 is to regularly check whether the status of the CPU core and the simulation environment resource pool is normal, and to promptly discover and correct the abnormality of the CPU hyperthreading state and the error storage information of the simulation environment.

[0106] In a specific implementation, the mode configuration module 22 determines the physical cores for executing the simulation environment by executing the physical core configuration mechanism according to the simulation environment mode selected by the user. The initial state of the CPU core is that the hyperthreading is turned on. The mode configuration module 22 adjusts the hyperthreading state according to the simulation environment requirements, and processes the performance mode and function mode by executing the physical core configuration mechanism.

[0107] like Figure 2 As shown, the physical core configuration mechanism is as follows:

[0108] When the simulation environment mode selected by the user is the performance mode, the work of the mode configuration module mainly includes finding an idle physical core and disabling the hyperthreading of the physical core. The specific steps are as follows:

[0109] S1001: Find idle physical cores:

[0110] First, based on the simulation environment information, find out the logical core numbers bound to all current simulation environment processes; then, determine the currently idle logical cores based on the logical core numbers bound to all current simulation environment processes, and further determine the idle logical core numbers among the available logical cores in the simulation environment.

[0111] If there is no idle logical core at present, it is considered that the simulation environment application has failed and an error message is returned.

[0112] If there is an idle logical core currently, the number of the idle logical core is obtained. Based on the number of the idle logical core and the mapping relationship between the logical core and the physical core, the idle physical core is screened out; wherein the two logical cores corresponding to the idle physical core are both in an idle state.

[0113] At this time, if the idle physical core cannot be screened out, it is deemed that the simulation environment application has failed and an error message is returned; if the idle physical core can be screened out, the numbers of the two logical cores corresponding to the idle physical core are determined, and are recorded as a and b, respectively, a<b; the two logical cores corresponding to the idle physical core are recorded as logical core a and logical core b, respectively.

[0114] S1002: Disable the hyperthreading of the physical core:

[0115] Since disabling the hyperthreading of a physical core is achieved by controlling the enabling or disabling state of a corresponding logical core, first, the state of logical core b is set to offline; then logical core a is used as a logical core for running the simulation environment process.

[0116] At this point, the simulation environment process can be assigned to the logical core a, so that the corresponding physical core can run the simulation environment process in performance mode.

[0117] When the simulation environment mode selected by the user is the performance mode, the work of the mode configuration module mainly includes giving priority to the hyperthreaded physical cores to execute the simulation environment. If such physical cores do not exist, the idle physical cores are used to execute the simulation environment. The specific steps are as follows:

[0118] S1003: Find idle logical cores:

[0119] First, based on the simulation environment information, find out the logical core numbers bound to all current simulation environment processes; then, determine the currently idle logical cores based on the logical core numbers bound to all current simulation environment processes. If there are no idle logical cores, it is considered that the simulation environment application has failed and an error message is returned.

[0120] If there is currently an idle logical core, the number of the idle logical core is obtained; at this time, based on the number of the idle logical core and the mapping relationship between the logical core and the physical core, the physical core corresponding to the idle logical core is determined as the physical core to be screened.

[0121] Then, according to the mapping relationship between the logical cores and the physical cores, it is determined whether another logical core mapped to the physical core to be screened is in use.

[0122] If yes, it can be determined that the physical core is bound to a simulation environment process, and the idle logical core mapped to the physical core is used as the logical core for running the simulation environment process. That is, according to the mapping relationship between the logical core and the physical core, the physical core mapped to it is preferentially selected as an idle logical core in use to run the simulation environment process (that is, another logical core mapped to the same physical core as the logical core has a process bound to it).

[0123] If all the physical cores to be screened are not bound to the simulation environment process, the idle logical core with the smallest number is used as the logical core for running the simulation environment process.

[0124] At this point, the simulation environment process can be assigned to the screened logical cores, so that the corresponding physical cores can run the simulation environment process in the functional mode.

[0125] In a specific implementation, after receiving a simulation environment release request, the simulation environment release processing unit 3 restores the hyperthreading state of the physical core bound to the simulation environment by configuring the restoration module 32 to execute the hyperthreading state recovery mechanism. Figure 3 As shown, the hyperthreading state recovery mechanism is as follows:

[0126] First, the simulation environment information is obtained from the resource management pool, the process number of the corresponding simulation environment process is found out according to the simulation environment release request, and the simulation environment mode of the simulation environment process is determined.

[0127] When the simulation environment mode is the performance mode, based on the simulation environment information, the logical core number X bound to the simulation environment process is found according to the process number of the simulation environment process; based on the mapping relationship between the logical core and the physical core, according to the logical core number X, the physical core mapped by the logical core X is found, and the number Y of another logical core mapped by the physical core is determined; the state of the logical core Y is set to online.

[0128] When the simulation environment mode is functional mode, no operation is performed.

[0129] After the hyperthreading state recovery mechanism is executed, the simulation environment is released and the relevant information of the resource management pool is updated.

[0130] In a specific implementation, under normal circumstances, the simulation environment release operation is performed by the user, but there are also other situations where the simulation environment program terminates abnormally, such as insufficient memory, simulation program bugs, initial data errors, etc. In order to handle these abnormal situations, the system is provided with a resource management pool maintenance unit 5.

[0131] Since the simulation environment configuration of the functional mode does not need to change the hyperthreading state of the physical core to which it is bound, the abnormal exit of the program does not affect the physical core to which it is bound. However, the hyperthreading of the physical core to which it is bound is turned off during the simulation environment configuration of the performance mode, and the abnormal exit of the program cannot restore the initial state of the core. Therefore, the resource management pool maintenance unit 5 is used to filter out the simulation environment process that abnormally exits the performance mode and perform correction processing. The resource management pool maintenance unit 5 can implement the above functions by executing the resource maintenance process. Figure 4 As shown, the resource maintenance process includes the following steps:

[0132] Step 1: Filter out the processor cores in the idle state. Specifically, filter out the logic cores in the idle state based on the simulation environment information at each preset time interval.

[0133] Step 2: Filter out n processor cores in the offline state. Specifically, filter out n logical cores in the offline state from the logical cores in the idle state, and set a variable i, with an initial value of i set to 1. The n processor cores in the offline state are filtered one by one.

[0134] Step 3: Find the physical core mapped to the ith processor core according to the mapping relationship between the logical cores and the physical cores. Specifically, determine the physical core corresponding to the ith logical core according to the mapping relationship between the logical cores and the physical cores.

[0135] Step 4: Find another logical core that is mapped to the physical core. Specifically, determine another logical core other than the i-th logical core among the two logical cores mapped to the physical core according to the mapping relationship between the logical cores and the physical cores.

[0136] Step 5: Determine whether the logic core is in an idle state. If yes, execute step 6; if no, execute step 7.

[0137] Step 6: Enable the hyperthreading of the corresponding physical core, and execute step 8. Specifically, the hyperthreading of the corresponding physical core is enabled by setting the state of the logical core to online.

[0138] Step 7: Determine whether the simulation environment mode of the logic core is the performance mode; if so, execute step 8; if not, execute step 6.

[0139] Step 8: i=i+1;

[0140] Step 9: Determine whether i≥n; if so, end directly; if not, execute step 3.

[0141] In the above resource maintenance process, firstly, all processor cores in an idle state are screened out.

[0142] Then, filter out all the processor cores in the offline state, and perform the following screening on these cores one by one:

[0143] 1) Determine the physical core corresponding to the CPU core according to the mapping relationship between the logical core and the physical core;

[0144] 2) Determine another logical core mapped to the physical core (normally, the logical core with a smaller number), and determine whether it is an idle CPU core:

[0145] If yes, enable hyperthreading for the physical core and continue to check the next core;

[0146] If not, determine whether the simulation environment it is bound to is in performance mode:

[0147] If yes, continue to check the next core;

[0148] If not, turn on hyperthreading for that physical core and continue checking the next core.

[0149] Based on the dynamic configuration system of the above simulation environment, in order to better illustrate the implementation process of the specific functions of the system, the operation process of each functional unit of the system is explained with a specific example, as follows:

[0150] 1. Design a database table structure as a resource management pool to store the core binding information and mode information of the simulation environment process. For example, define the database table structure as follows:

[0151] id: Auto-increment primary key that uniquely identifies each record.

[0152] pid: Process ID.

[0153] command: The command name or path of the process.

[0154] cpu_affinity: CPU affinity of the process (bound CPU core information).

[0155] status: The status of the process (such as running, terminated, etc.).

[0156] mode: performance mode or functional mode.

[0157] 2. Use the basic configuration unit to perform the following operations:

[0158] Enable hyperthreading through BIOS; allocate 8 available logical cores for the simulation environment to the current server, numbered 0-7; every two logical cores share one physical core resource, and define the mapped 4 physical core numbers as 0, 1, 2, and 3 respectively. At this time, set the mapping relationship between logical cores and physical cores. The specific mapping relationship is shown in Table 1 below:

[0159] Table 1: Mapping relationship between logical cores and physical cores

[0160] Logic Core 0 1 2 3 4 5 6 7 Mapped physical cores 0 0 1 1 2 2 3 3

[0161] At this time, all CPU cores are online, and a simulation environment of up to 8 functional modes can be configured.

[0162] 3. Use the user simulation environment to apply for the processing unit to perform the following operations:

[0163] 3.1. When the simulation environment mode selected by the user is the performance mode, first search the database for the logical core numbers bound to all current simulation processes, and obtain that the current logical cores 0, 1, and 2 are bound. Then, based on the information of all available cores in the simulation environment that is initialized, determine that the idle logical core numbers in the available logical cores of the simulation environment are 3, 4, 5, 6, and 7. At this time, logical cores 4 and 5 are also mapped to physical core 2, and are both in an idle state, indicating that physical core 2 is idle. Finally, set the state of logical core 5 to offline, and use logical core 4 as the CPU core bound to the simulation environment to be run, start configuring the simulation environment, and update the database information.

[0164] 3.2. When the simulation environment mode selected by the user is the functional mode, first search the database for the logical core numbers bound to all current simulation processes, and obtain that the current logical cores 0, 1, and 2 are bound. Then, based on the information of all available cores in the simulation environment that is initialized and configured, determine that the idle logical core numbers in the available logical cores of the simulation environment are 3, 4, 5, 6, and 7. At this time, it can be determined that logical core 3 is mapped to physical core 1, and the other logical core 2 mapped to physical core 1 is non-idle. Finally, select logical core 3 as the CPU core bound to the simulation environment to be run, start configuring the simulation environment, and update the database information.

[0165] 4. Use the simulation environment to release the processing unit to perform the following operations:

[0166] If the simulation environment release processing unit receives a release request from the simulation process, it finds out that the simulation process is in performance mode and is bound to logical core 4. By querying Table 1, it is known that logical core 4 and logical core 5 belong to physical core 2, and it is determined that logical core 5 is in the offline state. Finally, logical core 5 is configured to be online, the database is updated, and the simulation environment release is executed.

[0167] If the simulation environment release processing unit receives a release application of a simulation process, it finds out that the simulation process is in a functional mode, directly executes the simulation environment release and updates the database information.

[0168] 5. Use the resource management pool maintenance unit to perform the following operations every 30 minutes:

[0169] 5.1. Query the database and obtain the logical core serial numbers of all current simulation processes to find that logical core 0, logical core 1, and logical core 2 are in use.

[0170] 5.2. It is further calculated that the processor cores in the idle state are logical core 3, logical core 4, logical core 5, logical core 6, and logical core 7.

[0171] 5.3. Query the processor cores in the offline state based on the cpu information. Find that logical core 3 and logical core 5 are in the offline state. Perform the following screening on logical core 3 and logical core 5:

[0172] First, according to the mapping relationship between logical cores and physical cores, it is determined that logical core 3 is mapped to physical core 1, and logical core 5 is mapped to physical core 2.

[0173] At this time, another logical core 2 mapped to the physical core 1 can be determined based on the logical core 3. After querying, the simulation process bound to the logical core 2 is in performance mode, and the process is running normally, so the logical core 5 is checked again.

[0174] According to logical core 5, another logical core 4 mapped to physical core 2 can be determined. After query, it is found that there is a process bound to core 4, but according to the process number, it is found that the process does not exist, indicating that the simulation program exits abnormally. Therefore, by configuring logical core 5 to be online, physical core 2 is restored to its initial state and the database information is updated.
