Use project limits (also called capacity allowance) to control how much of a capacity block group (CBG) a project can consume. This article explains how to view, set, remove and disable project limits for capacity block groups.

​
Prerequisites

Make sure you are in a group that has the admin role within your tenant; for example, the default admins group. You can check this in the Administration → IAM section of the web console.

​
How to view project limits

  1. In the web console, go to  Administration → Limits.
  2. Open the Capacity block groups tab.
  3. Click the capacity block group that you want to view.
  4. Open the Project limits tab.
The table shows the following for each project:
  • Usage: Current GPU consumption from the CBG. If usage exceeds the project limit or the current CBG size, running workloads continue, but new CBG allocations are blocked. Usage above the CBG size is billed at pay-as-you-go (PAYG) prices.
  • Limit: Configured and effective limit of GPU consumption, if they differ. The effective limit is always capped at the current CBG size.

​
How to set a custom project limit

  1. In the web console, go to  Administration → Limits.
  2. Open the Capacity block groups tab.
  3. Click the capacity block group that you want to set a project limit for.
  4. Open the Project limits tab.
  5. In the row of the required project, click → Set custom limit.
  6. Enter the limit value and click Save changes.
Setting the limit to 0 disables CBG usage for the project.

​
How to remove a project limit

Removing a project limit removes the configured value. The effective limit becomes the current capacity block group size.
  1. In the web console, go to  Administration → Limits.
  2. Open the Capacity block groups tab.
  3. Click the capacity block group that you want to remove a project limit from.
  4. Open the Project limits tab.
  5. In the row of the required project, click → Limit by CBG size.

​
How to disable CBG usage for a project

When you disable CBG usage, running workloads continue, but can’t restart once stopped. New CBG allocations are not possible.
  1. In the web console, go to  Administration → Limits.
  2. Open the Capacity block groups tab.
  3. Click the capacity block group where you want to disable CBG usage for a project.
  4. Open the Project limits tab.
  5. In the row of the required project, click → Disable CBG usage.
You can also disable CBG usage for a project by setting the project limit to 0.
