Abstract

The invention discloses a computing terminal starting method which is applied in a cluster system containing a plurality of computing terminals. The method includes: a computing terminal receives a starting trigger signal; a random number is generated according to the starting trigger signal and used for determining delay time; and the computing terminal is controlled according to the delay time to arrive at the delay time to perform starting operation. Starting delay of each computing terminal in the cluster system is controlled through the generated delay time so as to prevent each computing terminal in the cluster system from being started at the same time. Voltage pulse of the cluster system cannot arrive at a high value at the electric moment, moment fluctuation of a local area network power grid is avoided, and operating stability of other electric devices in the power grid is guaranteed. For the computing terminal, the computing terminal cannot be influenced by fluctuation of external voltage, and starting and electrifying stability of each computing terminal can be improved.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a method and system for starting up a computing terminal and a computing terminal. Background technique [0002] In a computer cluster application environment, there are usually dozens or even more computing terminals, and these computing terminals can be managed centrally, for example, power-on control is performed on all computing terminals. Taking the electronic classroom in the prior art as an example, each electronic classroom includes multiple computing terminals, and the BIOS power management option of each computing terminal is set to "Power On". It will turn on automatically without manual operation. Based on the above booting process, the administrator of the electronic classroom only needs to switch on the switch when starting up, and then can complete the simultaneous booting operation of multiple computers in the entire classroom. [0003] In...
