Racked GPU system

An Information Handling System (IHS), comprising:

• a rack system defining a plurality of device housings;
• an interposer device housed in the rack system adjacent the plurality of device housings;
• a plurality of compute devices that each include a plurality of Graphics Processing Units (GPU) devices, wherein each of the plurality of compute devices is housed in a respective one of the plurality of the device housings and connected to the interposer device;
• and
• at least one switch system that includes a plurality of networking processing devices, wherein each at least one switch system is housed in the rack system opposite the interposer device from the plurality of compute devices and the plurality of device housings, and connected to the interposer device, wherein each of the plurality of GPU devices in the plurality of compute devices communicates via the interposer device and the at least one switch system with at least one of the others of the plurality of GPU devices in the plurality of compute devices.

A method for providing a racked Graphics Processing Unit (GPU) system, comprising:

• positioning, by an interposer device, in a rack system defining a plurality of device housings such that the interposer device is located adjacent the plurality of device housings;
• positioning, by each a plurality of compute devices that each include a plurality of Graphics Processing Units (GPU) devices, in a respective one of the plurality of the device housings;
• connecting, by each of the plurality of compute devices in response to being positioned in the respective one of the plurality of the device housings, to the interposer device;
• positioning, by at least one switch system that includes a plurality of networking processing devices, in the rack system opposite the interposer device from the plurality of compute devices and the plurality of device housings;
• connecting, by the at least one switch system in response to being positioned in the rack system, to the interposer device to communicatively couple each of the plurality of networking processing devices in that switch system to each of the plurality of GPU devices in each of the plurality of compute devices.
