Preparing GPU Resources
This section describes how you can plan and prepare basic software and hardware before using GPU capabilities.
Basic Planning
Resource |
Version |
---|---|
Cluster |
v1.25.15-r7 or later |
OS |
Huawei Cloud EulerOS 2.0 |
System architecture |
x86 |
GPU |
T4 and V100 |
Driver version |
Only GPU driver 470.57.02, 510.47.03, or 535.54.03 for GPU virtualization |
Container runtime |
containerd |
Add-ons |
The following add-ons must be installed in a cluster:
|
Step 1: Add GPU Nodes to a Cluster and Label the Nodes
If there are GPU nodes that comply with the basic planning in your cluster, skip this procedure.
- Add GPU nodes to your cluster. For details, see Adding Nodes to On-Premises Clusters.
- Label the nodes with accelerator: nvidia-{GPU model}. For details, see Adding Labels/Taints to Nodes.
Figure 1 Labeling nodes that support GPU virtualization
Step 2: Install the Add-ons
If the add-ons that comply with the basic planning have been installed in your cluster, you can skip this procedure.
Before restarting a node, evict all pods on that node. Make sure to reserve GPU resources to avoid pod scheduling failures during node drainage. Insufficient resources can affect services.
- Log in to the UCS console and click the cluster name to access the cluster console. In the navigation pane, choose Add-ons. In the Add-ons Installed area, check whether the Volcano and gpu-device-plugin add-ons have been installed.
- If the gpu-device-plugin add-on is not installed, install it by referring to gpu-device-plugin.
To enable GPU virtualization, install the Volcano add-on. For details, see Volcano.
