Data transmission method and device based on high-speed signal switching chip and medium

Abstract

The invention discloses a data transmission method and device based on a high-speed signal switching chip and a medium. The method comprises the following steps: acquiring a first chip interface of afirst high-speed signal switching chip, a first CPU interface of a first CPU, a second chip interface of a second high-speed signal switching chip and a second CPU interface of a second CPU, which arephysically connected with a target high-speed signal switching chip in advance; setting a communication connection relationship among the first chip interface and the first CPU interface, the secondchip interface and the second CPU interface in the target high-speed signal switching chip according to a preset communication rule to obtain a plurality of transmission paths; when the to-be-transmitted data exists, selecting the target transmission pat from the plurality of transmission paths to transmit the to-be-transmitted data. The transmission paths of the first high-speed signal switchingchip in the first processing end and the second high-speed signal switching chip in the second processing end are increased, so that the data transmission efficiency between GPUs in different processing ends can be improved.

Description

technical field [0001] The invention relates to the field of data transmission, in particular to a data transmission method, device and computer-readable storage medium based on a high-speed signal switching chip. Background technique [0002] In recent years, HPC (High performance computing, high-performance computing) is more and more widely used in servers. Such as figure 1 A schematic diagram of the structure of HPC proposed for the prior art. In the CUDA (computeunified Device Architecture, unified computing device architecture) with NVIDIA, the GPU in the same processing terminal performs information exchange with the CPU through the high-speed signal switching chip SW. Different The GPU in the processing end performs information exchange through the CPU transmission link between the CPUs in different processing ends. For example, the information exchange between GPU1~GPU4 and GPU5~GPU8 needs to pass through the CPU transmission link between CPU0 and CPU1. Realize da...
