GPUs

Current Status

This page is intended to represent the current state (for deployments in the wild) of how to provide GPU capability within an OpenStack cloud. We also provide links (with comments on currency) to older information on this topic. The future section looks at what is or might be coming upstream.

Today there are two primary possibilities for integrating GPU acceleration "natively" into an OpenStack cloud without any external services. These are:

  • Ironic bare-metal cloud having GPU compute nodes
  • Nova VM-based compute (e.g. Libvirt+KVM) with PCI passthrough

GPU passthrough known good/working & bad/not-working configs

Working GPU passthrough into virtual machines (as possible with PCI passthrough support in Nova) requires specific hardware features which are not always reliably implemented or available. This page aims to collect knowing working and particularly *not*-working hardware combinations of platform and GPU models so that existing and potential deployers can knowledge-share and avoid expensive/nasty surprises. Systems vendors may also be able to use this to indicate compatibility.

The same GPU may appear as both working and not working due to platform and or software issues.
