Abstract

The invention relates to the technical field of server architecture, Provided are a device and a method for freely switching GPU server topology. The device includes a CPU board, GPU board, a PCIE board and a switch board. A PCIE Switch is arranged on the switch board. Four PCIE interfaces are arranged on the PCIE Switch, and the interfaces are used to connect with the CPU board, the GPU board andthe PCIE board. The switch board changes connection relationship among the four PCIE interfaces by switching working modes, and realizes changes of a topology structure of the GPU server. By introducing thea switch board and configuring the working mode of the switch board, the device and the method realize dynamic adjustability of a PCIE interconnection structure, so that a user can switch between two topological structures without changing an internal structure of the server under the condition of not opening a case, so as to satisfy computing requirements of different scenes, and improve operation and maintenance efficiency of a data center.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of server architecture, and in particular to an apparatus and method for freely switching GPU server topology. Background technique [0002] Artificial intelligence technology (referred to as AI) is one of the top ten technologies in the future. AI has extremely high requirements for computational accuracy and computational complexity, which poses a severe challenge to the performance and reliability of its hardware carrier. GPU servers integrate high-density GPU groups to provide more efficient computing resources, so they are widely used in the AI ​​field. The GPU server adopts the CPU+GPU heterogeneous computing architecture. Usually, the CPU is responsible for issuing instructions, controlling calculations and other core tasks. The GPU acts as a coprocessor, accepting the data sent by the CPU for internal calculations, and then feeding back the results to the CPU. . The characteri...
