Embodiment Construction

[0063] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0064] refer to figure 1 , the present invention proposes a method for switching GPU topology without cables, with a corresponding operating system, the operating system is associated with the PCH, and the PCH has a corresponding GPIO, including:

[0065] S1: The operating system is powered on and initialized;

[0066] S2: Change the state of the GPIO of the PCH according to the preset method;

[0067] S3: store the state information after the GPIO of the PCH is changed;

[0068] S4: Perform a system reset to complete the switching of the GPU topology.

[0069] In the embodiment of the present invention, the GPU server has three commonly used modes, which are general mode, balanced mode and cascade mode. The operating system includes BIOS (Basic Input Output System, basic input and output system) and BMC (Baseboar...

Abstract

The invention discloses a method, a device and equipment for switching GPU (Graphics Processing Unit) topology without a cable, the method for switching GPU topology without a cable is provided with acorresponding operating system, the operating system is correspondingly associated with a PCH (Platform Controller Hub), the PCH is provided with a corresponding GPIO (General Purpose Input / Output),and the method comprises the following steps of: electrifying the operating system and finishing initialization; changing the state of GPIO of the PCH according to a preset mode; storing the changed state information of the GPIO of the PCH; and carrying out system reset, and completing switching of the GPU topological structure. Free combination of GPU topologies is achieved by setting different states of GPIOs of the PCH. Switching of common applications can be realized without any change operation of a user on hardware, so that the universality of the GPU server is improved. Meanwhile, in terms of hardware, stock for different hardware of different topological structures can be omitted, the stock types of materials are reduced, and funds are saved.

Description

technical field [0001] The present invention relates to the field of servers, in particular to a method, device and equipment for switching GPU topology without cables. Background technique [0002] The current digitalization of information and the application of various artificial intelligences have replaced artificial intelligence in all walks of life for intelligent analysis of various complex data.
