Abstract

Learn how GPUs, NVMe drives and other IO devices can be efficiently shared in a PCI Express cluster using SmartIO from Dolphin Interconnect Solutions.Traditionally, IO devices have been statically assigned to a single root complex (host machine), and features such as hot-add, device migration and remote access is not supported in a flexible way without complex software frameworks. Dolphin SmartIO eliminates these restrictions and provide a flexible framework for handling PCIe devices and systems. Devices such as GPUs, NVMe drives and other IO devices can be flexibly accessed from remote systems. We demonstrate how SmartIO is implemented using standard PCIe and Non-Transparent Bridging, show that our system gets near native performance when moving data from local GPUs to remote NVMe drives, and how we can dynamically add more GPUs to scale performance.
