# HPC spaces

## HPC integration

Need more computing power for your workloads? On Nuvolos, you can run interactive HPC workloads by scaling up your application size. If the sizes included in your plan aren't sufficient, consider using [credit-based sizes](https://docs.nuvolos.com/features/applications/application-resources).

**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](https://docs.nuvolos.com/pricing-and-billing/resource-pools-and-budgets#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](https://docs.nuvolos.com/user-guides/education-guides/configuring-student-applications#scheduled-startup-with-gpu) for students.
* A [credit quota](https://docs.nuvolos.com/user-guides/education-guides/courses-with-gpus#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

**To enable HPC features in your space:**

Navigate to your project. Then on the sidebar (Cogwheel) **Course/Project/Dataset Settings** > **Course/Project/Dataset Configuration**:

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.
