Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, rather than whole embodiments.Based on this
Embodiment in invention, without making creative work, what is obtained is every other by those of ordinary skill in the art
Embodiment belongs to the scope of the present invention.
In order to enable those skilled in the art to better understand the solution of the present invention, with reference to the accompanying drawings and detailed description
The present invention is described in further detail.
Next, the method that a kind of control GPU frequency reducings that the embodiment of the present invention is provided are discussed in detail.Fig. 1 is the present invention
A kind of flow chart of the method for control GPU frequency reducings that embodiment provides, this method include：
S101：Obtain the temperature value of GPU.
Baseboard management controller (Baseboard Management Controller, BMC), may be implemented server
Remote management and control.In embodiments of the present invention, the outer protection mechanism to GPU is established using BMC.
In the concrete realization, can be by the frequency reducing pin of BMC and GPU by bus bar, BMC is by bus to described
GPU sends temperature acquisition instruction, after GPU receives the temperature acquisition instruction of BMC transmissions, by bus by temperature current GPU
Value feeds back to BMC.
Temperature value current GPU reflects the working condition of GPU, when the temperature value is higher, illustrates that GPU is in higher negative
The operating status of lotus, in order to ensure the safe operation of GPU, it may be necessary to which down conversion process is carried out to it.
S102：Judge whether the temperature value is more than predetermined threshold value.
In embodiments of the present invention, by judging whether the current temperature values of GPU are more than predetermined threshold value, as whether right
GPU carries out the foundation of down conversion process.
Predetermined threshold value is used to indicate a warning value of GPU temperature, and the specific value of predetermined threshold value can be according to practical need
It asks and is set, do not limited herein.
When temperature value current GPU is more than the predetermined threshold value, illustrate that the temperature of GPU has reached the warning of its safe operation
Value, if not taking corresponding treatment measures, the temperature of GPU may continue to increase, thus the performance to GPU and safety
It affects.So when temperature value current GPU is more than the predetermined threshold value, BMC can carry out down conversion process to GPU, to
The rate of rise of GPU temperature is reduced, namely when the temperature value is more than the predetermined threshold value, executes S104.
S103：It is instructed to the GPU incoming levels, to realize the frequency reducing of the GPU.
The level value in need inputted to GPU can be carried in level command.Under normal operating conditions, the frequency reducing of GPU is drawn
Foot is in high level, and BMC can actively drag down the voltage value of the frequency reducing pin of GPU to the frequency reducing pin input low level of GPU,
To realize the down conversion process to GPU.After the frequency of GPU reduces, correspondingly, the temperature rate of rise of GPU can decline, realize
Control to GPU temperature achievees the purpose that protect GPU.
BMC obtains the temperature value of GPU it can be seen from above-mentioned technical proposal；Judge whether the temperature value is more than default
Threshold value；When the temperature value is more than the predetermined threshold value, then illustrate that the temperature of current GPU is higher, if taking measures not in time,
The damage of GPU is may result in, at this point, BMC can be instructed to the GPU incoming levels, to realize the frequency reducing of the GPU, works as GPU
Frequency reduce after, the speed of service can decline, its corresponding temperature rate of rise can decline, to effectively control GPU temperature
The purpose of protection GPU is realized in the growth of degree.BMC control GPU frequency reducings are independently of the outer guard method of GPU internal protection mechanism,
Itself and the protection mechanism collective effect inside GPU, provide dual fail-safe for GPU, protect GPU to greatest extent.
In embodiments of the present invention, in order to further enhance the safety of GPU, on the basis of predetermined threshold value is set, also
A limiting value can be preset.Specifically, BMC may determine that whether the temperature value is more than preset limit value；When described
When temperature value is more than the preset limit value, system power failure operation is executed.
Preset limit value is used to indicate the highest value of GPU temperature, when temperature value current GPU is more than the preset limit value
When, it is likely to result in the damage of GPU, therefore, when detecting that the current temperature values of GPU are more than the preset limit value, then
It is immediately performed system power failure operation.
In order to ensure the safety of GPU, a numerical value conduct than causing the temperature value that GPU is damaged slightly relatively low can be chosen
Preset limit value.
It is in order to enable GPU is out of service at once, to realize the timely protection to GPU to execute system power failure operation.
In the specific implementation, when BMC detects that the temperature value of GPU is more than preset limit value, automatic shutdown operation is executed, to realize system
Power down, at this time GPU be stopped, avoid the further promotion of GPU temperature.
By the way that limiting value is arranged, the timely protection to GPU may be implemented, GPU is effectively prevent to be damaged since temperature is excessively high.
In embodiments of the present invention, the overtemperature situation that GPU temperature is understood for the ease of user, can be arranged alarm mechanism.
Specifically, the total degree and temperature value that BMC can be counted in preset time period to GPU transmission temperature acquisition instructions are super
Cross the overtemperature number of the predetermined threshold value；When the overtemperature number and the total degree meet preset condition, carries out alarm and carry
Show.
Preset condition is the trigger condition that BMC carries out alarm.It in embodiments of the present invention, can be by calculating total time
The difference or ratio of number and overtemperature number execute alarm when calculated numerical value is more than preset numerical value.
By taking ratio calculated as an example, BMC calculates the ratio of the overtemperature number and the total degree；When the ratio is more than pre-
When the standard value first set, alarm is carried out.
Wherein, ratio can decimally, the form of score or percentage indicate, do not limit herein.
For example, BMC has sent 10 temperature acquisition instructions to GPU within a preset period of time, wherein there is the temperature of 8 GPU
Value has been more than predetermined threshold value, and by taking decimal form as an example, the ratio of overtemperature number and total degree is 8/10=0.8.
The ratio of overtemperature number and total degree is less than a numerical value equal to 1, correspondingly, standard value can take [0,1]
Between a numerical value.
The specific value of standard value can be set according to actual demand, when higher to GPU temperature requirements, can be incited somebody to action
Standard value is set as relatively low numerical value；When relatively low to GPU temperature requirements, standard value can be set to high value.
Alarm is set, it can be in order to the overtemperature situation of user's more intuitive understanding GPU temperature, in preset time period
Interior, BMC does not carry out alarm, then illustrates that the state of temperature of GPU is preferable；Within a preset period of time, BMC alarm and has carried
Show, then illustrates that the state of temperature of GPU is poor.
