Description

Technical Field

[0001] The present invention relates to the technical field of servers, and in particular to a method, device, server and medium for adjusting the frequency of a central processing unit. Background Art

[0002] Overclocking and downclocking of the server's central processing unit (CPU) are two common methods of hardware optimization and energy saving. Overclocking refers to increasing the CPU's operating speed to a higher speed than its default or nominal speed, thereby improving the overall performance of the server, processing tasks faster, and increasing the computing rate; downclocking refers to reducing the CPU's operating speed to a lower speed than its default or nominal speed, thereby helping to extend the life of the hardware and reduce power consumption and heat. Currently, CPU overclocking or downclocking is mainly achieved by setting the Basic Input / Output System (BIOS) startup items and using hardware jumpers.

[0003] However, both the method of modifying the CPU frequency by setting the BIOS startup item and the method of hardware jumper have problems in actual application. First, setting the BIOS startup item requires the server to be shut down and restarted to take effect, which will increase downtime and interrupt the running business, and have a serious impact on the normal use of the server. Secondly, although the hardware jumper method is technically feasible, in actual operation, it is necessary to manually open the server chassis and modify the jumper, which increases the complexity and risk of the operation. For scenarios where the computer room is far away, the operability of this method is greatly reduced. Not only does it take more time and manpower, but it may also cause hardware damage due to misoperation. It is not suitable for the pursuit of efficient and convenient server operation and maintenance.

[0059] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0060] The core of the present invention is to provide a central processing unit frequency adjustment method, device, server and medium to solve the current problem that the operating frequency of the server CPU cannot be adjusted efficiently and safely.

[0061] 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.

[0062] At present, both the solution of modifying the CPU frequency by setting BIOS startup items and the method of hardware jumpers have problems in practical applications. First, setting BIOS startup items usually requires the server to be shut down and restarted to take effect, which will increase downtime and interrupt the running business, affecting the normal use of the server. In addition, although the method of using hardware jumpers is technically feasible, in actual operation, the server chassis needs to be manually opened and modified, which increases the complexity and risk of operation. For scenarios far away from the computer room, the operability of this method is greatly reduced, it takes more time and manpower, and may also cause hardware damage due to misoperation. Therefore, this method is not suitable for the pursuit of efficient and convenient server operation and maintenance.

[0063] To solve the above problems, the present invention provides a method for adjusting the frequency of a central processing unit. It should be noted that the method is applied to a baseboard management controller (BMC). BMC is a controller specifically used for monitoring and management in a server, and its main functions include device information management, server status monitoring management, remote control management, and maintenance management. It records detailed information of the server, detects the health status of key components in real time, adjusts fan speed and power consumption, and reports abnormal conditions through industry-wide specifications. In addition, BMC also allows administrators to perform various operations remotely, and provides functions such as log management, user management, BIOS management, and alarm management to ensure stable operation and efficient management of the server.

[0064] Figure 1 A flow chart of a method for adjusting the frequency of a central processing unit provided by an embodiment of the present invention. Figure 1 As shown, the method includes:

[0065] S10: Reading the operation data of the target CPU according to a preset cycle.

[0066] The operation data at least includes the current utilization rate and the current power consumption value of the target central processing unit.

[0067] In a specific implementation, the operation data of the target CPU is first read according to a preset period. In this embodiment, there is no limitation on the preset period, for example, the preset period can be set to 10s or 20s, depending on the specific implementation situation.

[0068] It is understandable that, as a core component of the server, BMC has powerful functions, including real-time monitoring and adjustment of the target CPU operation data. In this embodiment, the operation data at least includes the current utilization and current power consumption value of the target CPU, and may also include data such as the operating temperature and operating frequency of the target CPU, which is not limited in this embodiment. It should be noted that during the operation of the server, the load and power consumption of the target CPU directly affect its performance and energy efficiency, so it is crucial to accurately control these two parameters. BMC can dynamically read the current utilization of the target CPU and express it in the form of a percentage, thereby displaying the load of the target CPU. When the server is idle or the task is light, the target CPU load is low, and the current utilization of the target CPU is also low; when the server faces a large number of computing tasks or high loads, the target CPU load increases, and the current utilization of the target CPU also increases. Usually, in order to maintain stable operation and good performance of the server, the current utilization of the target CPU is controlled at around 70%. However, in extreme cases, when the target CPU load reaches the limit, the current utilization of the target CPU will soar to 100%. In addition, the BMC can also read the current power consumption value of the target CPU in real time, which is one of the important indicators for measuring the energy efficiency ratio of the target CPU and is directly related to the operating cost and heat dissipation issues of the server.

[0069] In this embodiment, there is no limitation on the specific method of reading the operation data of the target CPU, which depends on the specific implementation situation.

[0070] S11: Determine a target operating frequency of a target central processing unit according to the operating data.

[0071] Furthermore, in the operation data of the target CPU read by the BMC, the current utilization rate can show the load of the target CPU, and the current power consumption value can measure the energy efficiency ratio of the target CPU and is directly related to the operation cost and heat dissipation problem of the server. Therefore, in order to obtain the best target operating frequency of the current target CPU, it is necessary to determine the target operating frequency of the target CPU according to the operation data. In this embodiment, there is no restriction on the method for determining the target operating frequency of the target CPU, which depends on the specific implementation situation.

[0072] S12: Determine a target power supply voltage of the target central processing unit according to the target operating frequency and the corresponding relationship between the power supply voltage and the operating frequency of the target central processing unit.

[0073] Among them, the power supply voltage of the target CPU is positively correlated with the operating frequency.

[0074] It is understandable that there is a direct connection between the operating frequency and the power supply voltage of the target CPU, and the level of the power supply voltage will directly affect the frequency of the target CPU. Specifically, when the power supply voltage increases, the frequency of the target CPU will usually increase accordingly; and when the power supply voltage decreases, the frequency of the target CPU will also decrease accordingly; that is, the power supply voltage of the target CPU is positively correlated with the operating frequency. This relationship makes it possible to control the frequency of the target CPU by adjusting the output voltage to the target CPU. Therefore, in order to adapt to different working scenarios, in this embodiment, the BMC determines the target supply voltage of the target CPU based on the obtained target operating frequency and the corresponding relationship between the power supply voltage and the operating frequency of the target CPU. In this embodiment, the specific process of determining the target supply voltage of the target CPU is not limited, and it depends on the specific implementation situation.

[0075] S13: Control the target central processing unit to operate at a target power supply voltage, so as to control the target central processing unit to operate at a target operating frequency.

[0076] Finally, after obtaining the target power supply voltage of the target CPU, the BMC controls the target CPU to operate at the target power supply voltage to control the target CPU to operate at the target operating frequency, thereby meeting the real-time workload and performance requirements of the server. In this embodiment, the specific method of controlling the target CPU to operate at the target power supply voltage is not limited.

[0077] In this embodiment, a dynamic CPU frequency adjustment mechanism is provided, which specifically determines the target operating frequency of the target CPU according to the operating data of the read target CPU, and determines the target power supply voltage of the target CPU according to the corresponding relationship between the target operating frequency and the power supply voltage and operating frequency of the target CPU; finally, the target CPU is controlled to operate at the target power supply voltage to control the target CPU to operate at the target operating frequency. The target operating frequency not only takes into account the current workload of the server CPU, but also takes into account the overall performance and power consumption requirements of the system, which can ensure that the server can maintain the best performance and power consumption state under different workloads, thereby improving the overall operation efficiency and stability of the server.

[0078] Based on the above embodiments, in some embodiments, reading the operation data of the target central processing unit according to a preset period includes:

[0079] S101: When the server is started, a calculation optimization frequency process is run;

[0080] S102: Based on the calculation optimization frequency process, the current utilization rate and the current power consumption value of the target central processing unit are read according to a preset period.

[0081] In order to achieve precise control of the target CPU operating frequency, the BMC in this embodiment adds a calculation optimization frequency process CalOptFreq. When the server starts, the calculation optimization frequency process CalOptFreq is automatically run, and the current utilization and current power consumption value of the target CPU are read every preset period. In this way, the target CPU operating data is read.

[0082] On this basis, the target operating frequency of the target CPU is determined according to the operating data, including:

[0083] S111: obtaining a rated power consumption value of a target central processing unit by calculating an optimized frequency process;

[0084] S112: Based on the calculation optimization frequency process, determine the target operating frequency of the target central processor according to the current utilization rate, current power consumption value, rated power consumption value and target operating frequency calculation formula of the target central processor;

[0085] S113: receiving an instruction for storing a target operating frequency, and storing the target operating frequency in a memory of the server according to the instruction.

[0086] It is understandable that each model of CPU has a rated power consumption value, which represents the power consumption level of the CPU under standard working conditions. Therefore, in order to accurately obtain the current power consumption status of the target CPU, it is necessary to read the current power consumption value of the target CPU in real time and compare it with the rated power consumption value of the target CPU, so that the BMC can accurately determine the current power consumption status of the CPU and make corresponding adjustments.

[0087] Specifically, the rated power consumption value of the target CPU is obtained by calculating the optimized frequency process CalOptFreq, and further based on the calculated optimized frequency process CalOptFreq, the target operating frequency of the target CPU is determined according to the current utilization rate, current power consumption value, rated power consumption value and target operating frequency calculation formula of the target CPU. The target operating frequency calculation formula is as follows:

[0088] ;

[0089] in, is the target operating frequency of the target CPU, is the current utilization of the target CPU; is the current power consumption value of the target CPU; is the rated power consumption of the target CPU.

[0090] Finally, an instruction representing the storage of the target operating frequency is received, and the target operating frequency is stored in the memory of the server according to the instruction, so as to facilitate the subsequent use of the target operating frequency data.

[0091] In this way, the target operating frequency data of the target CPU is determined. Through the method provided by this embodiment, the server can dynamically obtain the operating frequency that needs to be adjusted for the target CPU according to the actual load and power consumption, which not only realizes the accurate management and optimization of the server performance, but also greatly improves the energy efficiency ratio of the server while ensuring the performance.

[0092] Based on the above embodiments, in some embodiments, determining the target power supply voltage of the target CPU according to the target operating frequency and the corresponding relationship between the power supply voltage and the operating frequency of the target CPU includes:

[0093] S121: When the server starts, the voltage regulation module is run to control the process;

[0094] S122: obtaining a rated supply voltage and a rated operating frequency of a target central processing unit through a voltage regulation module control process;

[0095] S123: Based on the voltage regulation module control process and the corresponding relationship between the power supply voltage and the operating frequency of the target CPU, the target power supply voltage of the target CPU is determined according to the rated power supply voltage, the rated operating frequency and the target operating frequency of the target CPU.

[0096] In order to achieve precise control of the target CPU operating frequency, BMC also adds a voltage regulation module control process ControlVR. When the server starts, the voltage regulation module control process ControlVR automatically runs and obtains the rated supply voltage and rated operating frequency of the target CPU through the voltage regulation module control process ControlVR.

[0097] It is understandable that the rated supply voltage of the target CPU is a fixed value, which is set according to the specifications and performance requirements of the target CPU and has been determined in the hardware design stage. When the target CPU runs at the rated supply voltage, the operating frequency of the target CPU will also be close to its rated operating frequency, thereby ensuring that the performance of the target CPU is fully utilized.

[0098] Further, based on the correspondence between the voltage regulation module control process ControlVR and the supply voltage and operating frequency of the target CPU, the target supply voltage of the target CPU is determined according to the rated supply voltage, rated operating frequency and target operating frequency of the target CPU. It can be understood that from the above embodiment, the supply voltage and operating frequency of the target CPU are positively correlated, so there is the following correspondence:

[0099] ;

[0100] Thus, the target power supply voltage that the target CPU needs to meet when operating at the target operating frequency can be obtained through the above corresponding relationship, so that the target CPU can be operated at the target operating frequency by adjusting the target CPU to operate at the target power supply voltage.

[0101] Based on the above embodiments, in some embodiments, controlling the target central processor to operate at the target power supply voltage includes:

[0102] S131: Based on the voltage regulation module control process, the voltage regulation module chip is controlled to output the target power supply voltage to the target central processing unit through the integrated circuit bus link to control the target central processing unit to operate at the target power supply voltage and the target operating frequency.

[0103] It is worth noting that the Voltage Regulator Module (VR) chip, as the core component of server voltage regulation, plays a key role in the stable operation of the server by providing a stable and reliable power supply voltage for the CPU. As the core management component of the server, the BMC can accurately control the output voltage of the VR chip through specific interfaces and protocols, thereby achieving flexible adjustment of the CPU power supply voltage. In addition, the rated voltage of the VR chip output is a fixed value, which is set according to the CPU specifications and performance requirements. It is the rated power supply voltage when the CPU is operating normally. When the BMC controls the VR chip output voltage to be close to the rated voltage, the CPU frequency will also be close to its rated frequency, thereby ensuring that the CPU performance is fully utilized.

[0104] Therefore, in order to control the target CPU to run at the target power supply voltage, the voltage regulation module control process ControlVR is specifically based on the integrated circuit bus (Inter-Integrated Circuit, I2C) link to control the VR chip to output the target power supply voltage to the target CPU, thereby achieving the control of the target CPU to run at the target power supply voltage and target operating frequency.

[0105] Based on the above embodiments, in some embodiments, after controlling the target central processor to operate at the target power supply voltage, the method further includes:

[0106] S14: monitor the operating temperature of the target CPU;

[0107] S15: Determine whether the operating temperature of the target CPU is greater than a temperature threshold; if so, proceed to step S16;

[0108] S16: controlling the voltage regulating module chip through the integrated circuit bus link to reduce the power supply voltage output to the target central processor;

[0109] S17: Outputting alarm information indicating that the temperature of the target central processing unit exceeds the limit.

[0110] In a specific implementation, after controlling the target CPU to operate under the target power supply voltage, in order to avoid the target CPU performance degradation caused by abnormal temperature of the target CPU, the operating temperature of the target CPU is further monitored. It is determined whether the operating temperature of the target CPU is greater than the temperature threshold. In this embodiment, there is no restriction on the temperature threshold, which depends on the specific implementation situation.

[0111] If the operating temperature of the target CPU is not greater than the temperature threshold, the operating temperature of the target CPU continues to be monitored. If the operating temperature of the target CPU is greater than the temperature threshold, it is confirmed that the operating temperature of the target CPU exceeds the limit. In order to avoid affecting the performance and hardware of the target CPU, the VR chip is specifically controlled through the I2C link to reduce the power supply voltage output to the target CPU, thereby reducing the operating frequency of the target CPU and achieving the target CPU cooling treatment. At the same time, an alarm message indicating that the target CPU temperature exceeds the limit is output, so that the user can adjust the current target CPU task processing process according to the alarm information, or enhance the heat dissipation capacity of the target CPU to ensure the normal operation of the target CPU.

[0112] In addition, to avoid untimely cooling of the target CPU by adjusting the target CPU operating frequency, when the target CPU temperature is too high, the cooling effect can also be improved by adjusting the fan speed. First, enter the server BIOS setup interface and find the options related to fan control in the BIOS. Select the appropriate fan mode according to the current temperature and cooling requirements of the target CPU, and adjust the speed of a single fan by setting the minimum and maximum speed limits in the selected fan mode, so as to control the cooling fan of the target CPU and achieve timely cooling of the target CPU.

[0113] In addition, you can also use thermal management software to adjust the fan speed of the target CPU, such as CPU-Z, HWMonitor, or SpeedFan. After the software is running, find the fan control option; according to the temperature and cooling requirements of the target CPU, adjust the speed of a single fan by setting the minimum and maximum speed limits. In this way, the cooling fan of the target CPU is controlled and the target CPU is cooled in time.

[0114] Based on the above embodiments, in some embodiments, the method further includes:

[0115] S18: monitor the operating frequency of the target CPU;

[0116] S19: Determine whether the operating frequency of the target CPU is greater than a first frequency threshold; if the operating frequency of the target CPU is greater than the first frequency threshold, proceed to step S20; if the operating frequency of the target CPU is not greater than the first frequency threshold, proceed to step S21;

[0117] S20: controlling to reduce the power supply voltage output to the target central processing unit;

[0118] S21: Determine whether the operating frequency of the target CPU is less than the second frequency threshold; if the operating frequency of the target CPU is not less than the second frequency threshold, return to step S18; if the operating frequency of the target CPU is less than the second frequency threshold, enter step S22;

[0119] S22: Increase the number of concurrent requests that the server handles or runs computationally intensive tasks to increase the system load on the server.

[0120] The first frequency threshold is greater than the second frequency threshold.

[0121] In a specific implementation, in order to improve the working efficiency of the target CPU, the operating frequency of the target CPU may be further monitored to determine whether the operating frequency of the target CPU is greater than a first frequency threshold. In this embodiment, the first frequency threshold is not limited and is determined according to specific implementation conditions.

[0122] If the operating frequency of the target CPU is greater than the first frequency threshold, it is considered that the current operating frequency of the target CPU is too high. Continuing to operate at the current frequency will not only increase the power consumption of the server, but also damage the hardware of the target CPU. Therefore, in order to avoid the above problems, the power supply voltage output to the target CPU is controlled to be reduced, which can be achieved by reducing the output voltage of the VR chip to the target CPU, thereby reducing the operating frequency of the target CPU.

[0123] If the operating frequency of the target CPU is not greater than the first frequency threshold, then determine whether the operating frequency of the target CPU is less than the second frequency threshold. It should be noted that in this embodiment, there is no restriction on the size of the second frequency threshold, but it is necessary to satisfy that the first frequency threshold is greater than the second frequency threshold, depending on the specific implementation situation.
