Detailed Description
In a first illustrative embodiment of the present invention, a method of computing device temperature provisioning is provided. FIG. 1 is a flowchart illustrating a method for allocating a temperature of a computing device according to an embodiment of the present invention.
As shown in fig. 1, the method for adjusting the temperature of the computing device in this embodiment includes:
and S0, placing a plurality of arithmetic devices in a closed space to be subjected to temperature allocation, starting a program, and operating the arithmetic devices according to default parameters.
S1, acquiring the operating temperature parameter of the computing equipment and the current environment temperature of the closed space;
s2, determining whether to reduce the frequency and/or voltage of the operation equipment according to the temperature parameter of the operation equipment;
s3, determining the number and frequency values of the arithmetic devices required to be configured for temperature configuration according to the current environment temperature, the target environment temperature and the configuration ratio, wherein the configuration ratio is the ratio of the difference value of the current environment temperature and the target environment temperature relative to a reference value;
s4, according to the number of the arithmetic devices, selecting the configured arithmetic devices, configuring the frequency of the configured arithmetic devices, storing the configuration information into a database, and returning to the step S2 for cycle operation to realize the continuous control of the temperature.
In this embodiment, in order to continuously control the temperature of the enclosed space, after the configuration information in step S4 is stored in the database, the loop operation in step S2 is returned to be performed according to a fixed time period, that is, the temperature parameter of the operation of the computing device and the current ambient temperature of the enclosed space are periodically obtained, and the temperature of the computing device is adjusted, so that the file of the enclosed space can be continuously controlled.
In step S2, the obtained operating temperature parameter of the computing device is compared with a temperature protection threshold, and if the operating temperature parameter of the computing device is greater than the temperature protection threshold, the frequency and/or voltage of the computing device is reduced, so as to prevent the computing device from being restarted due to an excessively high temperature. The operating temperature parameters of the computing equipment comprise the maximum value of the chip temperature of each computing equipment and/or the air inlet temperature of each computing equipment.
In the step S3, if the current ambient temperature is higher than the target ambient temperature, determining the number of the computing devices to be configured and the reduced voltage or frequency thereof according to the allocation ratio; if the current environment temperature is equal to the target environment temperature, keeping the voltage and the frequency of the current operation equipment unchanged; and if the current environment temperature is lower than the target environment temperature, determining the number of the operation equipment to be configured and the increased voltage or frequency of the operation equipment according to the allocation ratio.
When the configuration is carried out according to the allocation ratio, the reference value is a temperature change difference value within a preset time obtained by configuring a preset number of operation devices to operate at a preset frequency in the previous operation process, or a temperature change difference value within a preset time obtained by configuring a preset number of operation devices to operate at a preset frequency in the preset operation process. And determining the number and frequency values of the computing equipment required to be configured for temperature adjustment according to the current ambient temperature, the target ambient temperature and the adjustment ratio.
Specifically, during the cyclic operation, the reference value is obtained by data during the previous operation:
(T1)n-T2n)/(T1n-1-T2n-1)
Wherein, T1nFor the current ambient temperature, T2nTo target ambient temperature, T1n-1For the current ambient temperature at the time of the last cycle of the recipe, T2n-1The target ambient temperature of the previous cycle. When the allocation ratio is greater than or equal to 1, it indicates that the temperature change amount required by the period is larger than that of the previous period, so that the number of the configured computing devices is unchanged, the frequency value of the configured computing devices is increased by a frequency step value INT (allocation ratio +0.5) compared with the frequency of the previous period, that is, the allocation ratio is rounded up and multiplied by the frequency step value; when the blending ratio is less than 1, it indicates that the temperature change amount required in the present cycle is less than that in the previous cycle. The frequency value of the configured computing devices is unchanged, and the number of the configured computing devices is: INT (number of configured computing devices of last cycle)Allocation ratio), i.e. the number of configured computing devices in the previous cycle, is rounded after the allocation ratio. The next adjustment is carried out by taking the previous adjustment as a reference, and the temperature can be effectively and accurately controlled by real-time adjustment.
Since the frequency change of the computing device is generally increased or decreased according to the frequency step, the frequency value of the computing device to be configured is determined according to the deployment ratio in the embodiment, that is, the frequency step value is determined to be changed several times. In particular, the deployment rate is a default value during the initial period. In an embodiment, when temperature adjustment is performed in an initial period, the configured computing devices are all computing devices in a closed space, increase and decrease are performed according to the target temperature relative to the current temperature, and if the target temperature is higher than the current temperature, a frequency step value is added to the frequency value of the computing device; if the target temperature is lower than the current temperature, the frequency value of the operation device is decreased by one frequency step value.
In step S4, the IP of the computing device to be configured is connected through Socket, and the API for changing the configuration provided by the control center corresponding to the IP is called to complete the configuration of the frequency of the computing device. And after the configuration is finished, storing the number of the operation equipment, the frequency value and the state value of whether the frequency is adjusted in the period into a database.
In this embodiment, the cycle of the cycle operation is a fixed time period, and if the time of each cycle is not a fixed value, the allocation ratio is also related to the time of the cycle and the time of the previous cycle.
The temperature allocation method of the computing equipment can control the output heat quantity of hundreds of computing equipment within a certain temperature range, and the output heat quantity and the temperature of the computing equipment are kept within a certain range by utilizing the heat quantity dissipated by the computing equipment, so that the computing equipment is applied to more application scenes, and more requirements are met.
In a second exemplary embodiment of the present invention, a method of computing device temperature provisioning is provided. FIG. 2 is a flowchart illustrating a method for allocating a temperature of a computing device according to an embodiment of the present invention.
In this embodiment, the temperature adjusting method of the computing device is used for a drying chamber which is relatively closed, so that the temperature of the drying chamber is kept within a certain range. Specifically, in this embodiment, 10 raspberry pies are provided, each raspberry pie has a static IP, and each raspberry pie is connected with 80 pieces of computing equipment. The air outlet of the computing equipment faces to a closed environment, so that the ambient temperature is kept within a certain range, such as 67-71 ℃.
As shown in fig. 2, after the program starts, the computing device operates according to default parameters, the PLL is set to 500MHz, and simultaneously the operating state parameters of all the computing devices are periodically obtained by connecting the IPs of all the raspberry groups through the Socket, including the maximum chip temperature Tmax of each computing device, and the number and frequency of the IPs scheduled in this period are determined.
Because the chip temperature of the computing equipment is very close to the temperature protection value in a relatively closed environment, the normal operation of the computing equipment needs to be ensured on the first premise. When temperature adjustment is carried out, the chip temperature maximum value Tmax of each computing device is firstly obtained, the chip temperature maximum value Tmax of each machine is traversed on the assumption that the temperature protection value is 107 ℃, and if the temperature protection value exceeds 107 ℃, the frequency and/or the voltage of all computing devices under an IP (Internet protocol) where a raspberry group connected with the computing devices is located are reduced to a certain fixed value.
The actual temperature in the closed environment is then obtained. In the embodiment, a plurality of sampling points are arranged in a closed environment, and the environment temperature is required to be 67-70 ℃. The sampling temperature of the sampling point 1 is a first actual temperature; the sampling temperature at sampling point 2 is the second actual temperature. If the first actual temperature and the second actual temperature are both higher than the upper limit of the required temperature range, that is, the first actual temperature threshold is 70 ℃, the frequency of the computing device needs to be reduced to reduce heat dissipation; if the first actual temperature and the second actual temperature are both lower than the lower limit of the required temperature range, that is, the second actual temperature threshold is lower than the lower limit of the required temperature range, the frequency of the computing device needs to be increased to increase heat dissipation, and the adjusted IP number and the adjusted frequency size need to be determined by comparing the temperature change after the adjustment in the previous cycle, in this embodiment, the second actual temperature threshold is 67 ℃. In this embodiment, the computing device may be configured with a frequency of 50-850, 25 being a frequency step. At the first deployment, the full IP is adjusted by default by one step 25 (up or down) and then stored in the database for reference for the next deployment.
Obtaining a current target environment temperature difference value through the actual temperature of the closed environment and the target environment temperature, reading a database to obtain the previous temperature change after the previous period of allocation, and dividing the previous temperature change by the current target environment temperature difference value to obtain the allocation ratio. If it is greater than 1, the number of IP steps is kept unchanged, and the integer part of the deployment ratio is used as the frequency step number, and the step number of each step is multiplied by 25. If the frequency is less than 1, the frequency is not changed, and the IP number is multiplied by the deployment ratio to take an integer. Therefore, the values of the number and the frequency of the IPs needing to be adjusted at this time are obtained, the IPs are connected through a Socket, and the API for changing the configuration provided by the raspberry pi is called to complete the configuration. When the configuration information is stored in the database, the state value of whether the frequency is adjusted or not is also stored. The aim is that if the configuration is not carried out at the last time, no reference value exists, and the configuration is carried out only according to the latest configuration mode.
In other embodiments, different from the first embodiment, the periodically obtaining the operating state parameter of all the computing devices is the air inlet temperature Temp of each computing device, when performing temperature adjustment, the air inlet temperature Temp of each computing device is first obtained, the air inlet temperature Temp of each computing device is traversed assuming that the temperature protection value is 83 ℃, and if the temperature protection value exceeds 83 ℃, the frequency and/or voltage of all the computing devices under the IP where the raspberry group connected to the computing device is located is reduced to a certain fixed value.
In other embodiments, different from the first embodiment, the operation state parameter of all the computing devices is periodically obtained as an air inlet temperature Temp of each computing device, when performing temperature adjustment, a chip temperature maximum value Tmax of each computing device and the air inlet temperature Temp of each computing device are first obtained, assuming that a chip temperature protection value of the computing device is 107 ℃ and an air inlet temperature protection value of the computing device is 83 ℃, traversing the chip temperature maximum value Tmax of each computing device and the air inlet temperature Temp of the computing device, and if the chip temperature maximum value Tmax of the computing device exceeds 107 ℃ or the air inlet temperature Temp of the computing device exceeds 83 ℃, reducing the frequency and/or voltage of all the computing devices below an IP where a raspberry connected to the computing device is located to a certain fixed value.
In a third exemplary embodiment of the present invention, an apparatus for calculating a temperature adjustment of a device is provided. FIG. 3 is a block diagram of a temperature adjustment device of a computing device according to an embodiment of the present invention. As shown in fig. 3, the apparatus includes:

and the configuration unit is used for selecting the configured operation equipment according to the number of the operation equipment, configuring the frequency of the configured operation equipment and storing the configuration information into a database.
The restart prevention unit compares the acquired temperature parameter of the operation equipment with a temperature protection threshold, and reduces the frequency and/or voltage of the operation equipment if the temperature parameter of the operation equipment is greater than the temperature protection threshold, so that the operation equipment is prevented from being restarted due to overhigh temperature. The operating temperature parameters of the computing equipment comprise the maximum value of the chip temperature of each computing equipment and/or the air inlet temperature of each computing equipment.

And determining the number and frequency values of the computing equipment required to be configured for temperature adjustment according to the current ambient temperature, the target ambient temperature and the adjustment ratio.
Specifically, the blending ratio is (T1)n-T2n)/(T1n-1-T2n-1)
Wherein, T1nFor the current ambient temperature, T2nTo target ambient temperature, T1n-1For the current ambient temperature of the previous cycle, T2n-1The target ambient temperature of the previous cycle. When the allocation ratio is greater than or equal to 1, it indicates that the temperature change amount required in the present period is greater than that in the previous period, so that the number of the configured computing devices is unchanged, and the frequency value of the configured computing devices is increased by a frequency step value INT (allocation ratio +0.5) compared with the frequency in the previous period; when the blending ratio is less than 1, it indicates that the temperature change amount required in the present cycle is less than that in the previous cycle. The frequency value of the configured computing devices is unchanged, and the number of the configured computing devices is: INT (number of configured computing devices of previous cycle. deployment ratio).
Since the frequency change of the computing device is generally increased or decreased according to the frequency step, the frequency value of the computing device to be configured is determined according to the deployment ratio in the embodiment, that is, the frequency step value is determined to be changed several times. In particular, the deployment rate is a default value during the initial period. In an embodiment, when temperature adjustment is performed in an initial period, the configured computing devices are all computing devices in a closed space, increase and decrease are performed according to the target temperature relative to the current temperature, and if the target temperature is higher than the current temperature, a frequency step value is added to the frequency value of the computing device; if the target temperature is lower than the current temperature, the frequency value of the operation device is decreased by one frequency step value.
