Updating an accelerator profile

You can update the existing accelerator profiles in your deployment. You might want to change important identifying information, such as the display name, the identifier, or the description.

Prerequisites

  • You have logged in to {productname-short} as a user with {productname-short} administrator privileges.

  • The accelerator profile exists in your deployment.

Procedure

  1. From the {productname-short} dashboard, click Settings → Notebook images.

    The Notebook images page appears. Previously imported notebook images are displayed. To enable or disable a previously imported notebook image, on the row containing the relevant notebook image, click the toggle in the Enable column.

  2. Click the action menu (⋮) and select Edit from the list.

    The Edit accelerator profile dialog opens.

  3. In the Name field, update the accelerator profile name.

  4. In the Identifier field, update the unique string that identifies the hardware accelerator associated with the accelerator profile, if applicable.

  5. Optional: In the Description field, update the accelerator profile.

  6. To enable or disable the accelerator profile immediately after creation, click the toggle in the Enable column.

  7. Optional: Add a toleration to schedule pods with matching taints.

    1. Click Add toleration.

      The Add toleration dialog opens.

    2. From the Operator list, select one of the following options:

      • Equal - The key/value/effect parameters must match. This is the default.

      • Exists - The key/effect parameters must match. You must leave a blank value parameter, which matches any.

    3. From the Effect list, select one of the following options:

      • None

      • NoSchedule - New pods that do not match the taint are not scheduled onto that node. Existing pods on the node remain.

      • PreferNoSchedule - New pods that do not match the taint might be scheduled onto that node, but the scheduler tries not to. Existing pods on the node remain.

      • NoExecute - New pods that do not match the taint cannot be scheduled onto that node. Existing pods on the node that do not have a matching toleration are removed.

    4. In the Key field, enter a toleration key. The key is any string, up to 253 characters. The key must begin with a letter or number, and may contain letters, numbers, hyphens, dots, and underscores.

    5. In the Value field, enter a toleration value. The value is any string, up to 63 characters. The value must begin with a letter or number, and may contain letters, numbers, hyphens, dots, and underscores.

    6. In the Toleration Seconds section, select one of the following options to specify how long a pod stays bound to a node that has a node condition.

      • Forever - Pods stays permanently bound to a node.

      • Custom value - Enter a value, in seconds, to define how long pods stay bound to a node that has a node condition.

    7. Click Add.

  8. If your accelerator profile contains existing tolerations, you can edit them.

    1. Click the action menu (⋮) on the row containing the toleration that you want to edit and select Edit from the list.

    2. Complete the applicable fields to update the details of the toleration.

    3. Click Update.

  9. Click Update accelerator profile.

Verification

  • If your accelerator profile has new identifying information, this information appears in the Accelerator list on the Start a notebook server page.
