Chapter 7. Enabling accelerators

Prerequisites

• You have logged in to your OpenShift cluster.
• You have the cluster-admin role in your OpenShift cluster.
• You have installed an accelerator and confirmed that it is detected in your environment.

Verification

• From the Administrator perspective, go to the Ecosystem Installed Operators page. Confirm that the following Operators appear:

  • The Operator for your accelerator
  • Node Feature Discovery (NFD)
  • Kernel Module Management (KMM)

• The accelerator is correctly detected a few minutes after full installation of the Node Feature Discovery (NFD) and the relevant accelerator Operator. The OpenShift CLI (oc) displays the appropriate output for the GPU worker nodes with accelerator cards. For example, here is output confirming that an NVIDIA GPU is detected:

  # Expected output when the accelerator is detected correctly
  oc describe node <node name>
