Description
Technical Field

Background
With the development of the technology, the application of the server is more and more extensive, wherein the CPU is used as the core technology of the server, and the power consumption of the CPU affects the power consumption and the pressure of the server.
In the actual test process, when the server is matched with components such as a CPU, a network adapter, a storage hard disk, a memory and the like, the whole system pressure test is a necessary test item for testing the stability of the server. However, when the pressure of the network adapter, the storage hard disk, the memory and other components starts to be tested, part of the CPU power consumption is additionally occupied, that is, the CPU power consumption is increased in the testing process. In the CPU stress test, a PTU tool provided by Intel corporation is often adopted to limit the power consumption of the CPU by using parameters, or a PASSMARKburn tool is adopted to adjust the power consumption utilization rate of the CPU to limit the power consumption utilization of the CPU. When the CPU is pressurized by using a common method, part of the CPU power consumption is occupied.
The existing solutions to the above problems and their disadvantages are as follows.
(1) The pressure of the network adapter, the thread number, the number of the storage hard disks, the number of the memories and the memory capacity all influence the power consumption of the CPU; when the pressure of the CPU is tested, the system blockage cannot be influenced by manually calculating the power consumption parameter of the CPU, and the operation is complicated.
(2) When the pressure of a plurality of different components is tested simultaneously, in order to avoid the system from being blocked to influence the pressure test of other components, the pressure test of a CPU is often put at the last to start the test; therefore, the component pressure test has execution sequence.
(3) The power consumption can be set by adopting a parameter setting method, but the method is static, and when other threads occupy a large amount of CPU power consumption, the CPU power consumption cannot be dynamically adjusted, so that the system is stuck.

In order to facilitate understanding of the present invention, the power consumption adjustment method based on the CPU stress test provided by the present invention is further described below with reference to the principle of the power consumption adjustment method based on the CPU stress test of the present invention and the process of performing the stress test on the CPU in the embodiment.
Specifically, the power consumption adjustment method based on the CPU pressure test includes:
the effect of the yes command in the shell is to repeatedly print a given content until it is terminated, the specified content being separated by a space, and if no content is specified, it will repeatedly print 'y' until it is terminated. The present invention uses the "yes > >/dev/null &" command to increase the pressure to the CPU.
When the pressure is added to the CPU, the pressure of the single command 'yes > >/dev/null &' cannot reach the value of automatically adjusting the power consumption of the CPU, and the pressure of the single command is small. The number of pressure strokes is gradually increased or decreased in a cyclic manner. The number of pressure lines is determined by the number of yes pressure lines. And monitoring the power consumption value of the CPU in real time in the whole pressure process. When the CPU power consumption value is lower, the lines of yes pressure are taken as dynamic parameters, and a circulating method is adopted to gradually increase the lines of pressure. And when the CPU power consumption value reaches a limit value, the circulation is exited, and the number of the pressure threads is not increased. When the real-time power consumption value of the CPU exceeds the maximum power consumption value in the pressure process, the number of the cores of the CPU is gradually reduced to reduce the number of the pressure threads in a circulating mode. And exiting the loop until the CPU power consumption value reaches the maximum power consumption value again.

In the CPU pressurization process, the number of yes threads of the CPU is taken as a dynamic parameter, and when the number of yes threads is gradually increased from 1, the number of the pressure threads increased to the CPU by a command of 'yes > >/dev/null &' is also increased at the same time, and the power consumption value of the CPU is gradually increased. The pressurization is gradually made with reference to the following method.

thread＝`ps–ef|grep–iyes|wc-l`
for((i＝$thread；i<＝$corecount；i++))
do
yes>/dev/null&
cpuusage＝`expr$cputimediff\*1000/$cpudiff`
if[$cpuusage-ge 90]；then
exit；

specifically, when other components are pressurized, if the CPU power consumption exceeds a limit value, the thread of the CPU pressurization is reduced.
threadsnum＝`ps–ef|grep–i yes|wc–l`
for((i＝$threadsnum；i>＝1；i--))
do
thread＝`ps–ef|grep–i yes|awk‘{print$2}’`
firstthread＝`echo$thread|awk‘{print$1}’`
