# HPC spaces

### HPC integration

Nuvolos supports interactive HPC workloads by scaling up application sizes. When the included subscription sizes are insufficient, [credit-based sizes](/reference/applications/application-resources.md) with dedicated CPU, RAM, and GPU resources can be enabled. 

To use interactive HPC features, space administrators need to enable them first. Once enabled, here's what you need to do:

**In research spaces:**

* Space administrators and Instance Editors can change application sizes.
* Credit costs are charged to the [resource pool associated with the space](/billing/resource-pools-and-budgets.md#mapping-spaces-to-resource-pools).

**In teaching spaces:**

* Space administrators can scale up applications in the **Master instance** anytime.
* Space administrators can distribute scaled applications to students.
* Space administrators can also define [scheduled startup with GPU](/how-to-guides/workflows-for-instructors/configuring-student-applications.md#scheduled-startup-with-gpu) for students.
* A [credit quota](/how-to-guides/workflows-for-instructors/courses-with-gpus.md#credit-quota-schedules) needs to be set for applications to scale in teaching spaces.
* Credit costs are charged to the resource pool associated with the space.

### Enable credit-based application sizes

1. Navigate to the Space.
2. On the sidebar, open the cogwheel menu and select **Course / Project / Dataset Settings → Course / Project / Dataset Configuration**.
3. In the configuration menu, toggle the button to enable scaling up to credit-based sizes.

You can't turn off access to credit-based sizes through self-service. If you need this feature disabled, contact support.
