Device and method for realizing double-GPU (Graphics Processing Unit) adaption

Abstract

The invention provides a device for realizing double-GPU (Graphics Processing Unit) adaption. The device comprises an X24 Riser card and an X8 Riser card, wherein the X24 Riser card, wherein the X24 Riser card is used for obtaining 16 paths of CPU0 PORT2 signals and 8 paths of CPU0 PORT3 signals from a mainboard, transmitting the 16 paths of CPU0 PORT2 signals to a first GPU and transmitting the 8paths of CPU0 PORT3 signals to the X8 Riser card; and the X8 Riser card is used for combining the 8 paths of CPU0 PORT3 signals obtained from the mainboard with the 8 paths of CPU0 PORT3 signals obtained from the X24 Riser card to form integral 16 paths of CPU0 PORT3 signals, and transmitting the 16 paths of CPU0 PORT3 signals to a second GPU. By use of the device, through the X24 Riser card andthe X8 Riser card, the configuration that a single CPU mounts double GPUs on the basis of a 5280M5 mainboard is realized so as to reduce the configuration cost of 5280M5 2GPU. The invention also provides a method for realizing the double-GPU adaption.

Description

technical field [0001] The present invention relates to the technical field of servers, in particular to a device and method for realizing dual-GPU switching. Background technique [0002] With the development of the Internet industry, Internet companies have higher and higher requirements for computing power of servers. Due to its excellent computing power, GPU has been used in places that require high computing power, and the requirements for GPU configuration in servers required by Internet companies are also getting higher and higher. [0003] In the dual-socket server NF5280M5, in order to increase the computing power of the server, the number of GPUs needs to be increased. The specific solution is: insert a GPU standard card into the X24 PCIE SLOT1 connected to CPU0, and insert it into the X24 PCIESLOT1 connected to CPU1. One GPU standard card to meet the requirements of two GPUs. [0004] In the above solution, the motherboard needs to be equipped with two CPUs, whi...
