Upgrading a Resource Pool Driver

Description

If GPUs or Ascend resources are used in a dedicated resource pool, you may need to customize GPU or Ascend drivers. ModelArts allows you to upgrade GPU or Ascend drivers of your dedicated resource pools.

There are two driver upgrade modes: secure upgrade and forcible upgrade.

• Secure upgrade: Running services are not affected. After the upgrade starts, the nodes are isolated (new jobs cannot be delivered). After the existing jobs on the nodes are complete, the upgrade is performed. The secure upgrade may take a long time because the jobs must be completed first.
• Forcible upgrade: The drivers are directly upgraded, regardless of whether there are running jobs.

Constraints

The target dedicated resource pool is in running, and the resource pool contains GPU or Ascend resources.

Upgrading the Driver

1. Log in to the ModelArts management console. In the navigation pane, choose Dedicated Resource Pools > Elastic Cluster.
2. In the Operation column of the target resource pool, choose More > Upgrade Driver.
3. In the Upgrade Driver dialog box, the driver type, number of nodes, current version, target version, and upgrade mode of the dedicated resource pool are displayed.
   • Target Version: Select a target driver version from the drop-down list.
   • Upgrade Mode: Select Secure upgrade or Forcible upgrade.
