The computing terminal in the embodiment of the application belongs to a computing terminal in a cluster system comprising a plurality of computing terminals, the computing terminals in the cluster system usually have the requirement of being started at the same time, and in order to avoid the problems that electric equipment in the cluster is unstable in work and the computing terminals are unstable in power on caused by starting at the same time, each computing terminal in the embodiment of the application controls the self-starting delay by generating a delay time, so that each computing terminal in the cluster system is prevented from being started at the same time.
Referring to fig. 1, a flowchart of a first embodiment of a power-on method of a computing terminal according to the present application is shown:
step 101: the computing terminal receives a power-on trigger signal.
The computing terminals in this embodiment may be specifically a desktop computer, a notebook computer, and the like, a cluster system is formed by a plurality of computing terminals, and after the cluster system is powered on, the cluster system can simultaneously trigger the closing of a power button of each computing terminal in the cluster system, so as to generate a power trigger signal; or, after receiving a uniform boot event, each computing terminal in the cluster system generates a boot trigger signal, where the boot event may be an event triggered by a mouse scroll operation or an event triggered by a network wakeup.
Step 102: and generating a random number according to the starting trigger signal, wherein the random number is used for determining the delay time.
Specifically, a range of the random number and the delay unit time that are stored in advance are acquired. And calling a random number generation algorithm to generate a random number belonging to the range of the random number, and determining the delay time according to the generated random number and the delay unit time.
Step 103: and controlling the computing terminal to execute the starting operation after the delay time is reached according to the delay time.
Each computing terminal in the cluster system executes the starting control operation according to the generated delay time, so that each computing terminal in the cluster system can be prevented from being started at the same time, the voltage pulse of the cluster system cannot reach a high value instantly at the moment of power-on, the instant fluctuation of a local area network power grid is avoided, and the working stability of other electrical equipment in the power grid is ensured; for the computing terminals, the stability of starting and electrifying each computing terminal can be improved because the computing terminals are not influenced by the fluctuation of external voltage.
Referring to fig. 2, a flowchart of a second embodiment of a booting method of a computing terminal according to the present application is shown:
step 201: the terminal receives a power-on trigger signal.
The computing terminals in this embodiment may be specifically a desktop computer, a notebook computer, and the like, a cluster system is formed by a plurality of computing terminals, and after the cluster system is powered on, the cluster system can simultaneously trigger the closing of a power button of each computing terminal in the cluster system, so as to generate a power trigger signal; or, after receiving a uniform boot event, each computing terminal in the cluster system generates a boot trigger signal, where the boot event may be an event triggered by a mouse scroll operation or an event triggered by a network wakeup.
Taking a cluster system as an example of an electronic classroom, the electronic classroom is provided with a plurality of computing terminals, and the BIOS Power management options of the computing terminals are all set to be Power On, so that after a Power supply is powered On, a starting button of the computing terminal is closed to generate a starting trigger signal.
Step 202: judging whether the pre-received selection command is to start a delayed starting function of the computing terminal, if so, executing step 203; otherwise, step 207 is performed.
In this embodiment, whether each computing terminal adopts the random delay startup or not may be preset, that is, the random delay function may be masked or turned off in advance. The selection function can be realized in a software mode or in a hardware jumper design, which are all general setting modes and are not described herein again. When the selection command received by the computing terminal in advance is to turn on the delayed starting function, the subsequent delayed starting operation is continuously executed, and when the selection command received by the computing terminal in advance is to turn off the delayed starting function, the starting operation is directly executed according to the prior art.
Step 203: and acquiring a random number range and delay unit time which are stored in advance.
Different random number ranges and delay unit time are adopted according to different numbers of the computing terminals in the cluster system, when the number of the computing terminals is small, the range of the random number can be set to be small, meanwhile, the delay unit time can be set to be 'millisecond', and when the number of the computing terminals is large, the setting range of the random number can be expanded. For example, for a cluster system containing one hundred computing terminals, a range of 0 to 500 random numbers may be set, with a delay unit time of "milliseconds".
Step 204: and calling a random number generation algorithm to generate a random number belonging to the range of the random number.

And executing the random number generation algorithm for each computing terminal in the cluster system respectively to generate random numbers which need to be used respectively.
Step 205: the delay time is determined based on the generated one random number and the delay unit time.
Each computing terminal combines the generated random number with the delay unit time, namely the delay time for starting the computing terminal.
Step 206: and controlling the computing terminal to execute the starting operation after the delay time is reached according to the delay time, and ending the current process.
Each computing terminal in the cluster system executes the starting control operation according to the generated delay time, so that the centralized starting event can be effectively dispersed into relatively independent individual starting operations, namely the starting time points of each computing terminal in the cluster system are different. Moreover, since the unit of the delay time is in milliseconds, the user does not feel the difference of the startup delay.
Step 207: and directly executing the starting operation according to the starting trigger information, and ending the current flow.
