OpenStack Caracal : Add Compute Nodes (GPU)2024/08/07 |
|
Add GPU attached Compute Nodes to use GPU on virtual machine instances. On this example, add [node02.srv.world] like follows.

On the new Node with GPU, Configure GPU Passthrough setting, refer to here for [1]. |
| [2] |
On the new Node with GPU, add it to Openstack Cluster as a Compute Node, refer to here. |
| [3] | On the new Node with GPU, Configure additional settings for Nova-Compute. |
