Switch GPU mode 10 min

INFO

Only Olares admins can change GPU modes. This helps avoid conflicts and keeps GPU performance predictable for everyone.

Olares lets you control how applications use GPU resources for workloads like AI, image and video generation, and gaming. You can choose different GPU modes depending on how your apps should share compute and memory.

Learning objectives

By the end of this tutorial, you will learn how to:

• Choose between the three GPU modes.
• Switch GPU mode in Settings.
• Configure app binding for App exclusive mode and Memory slicing mode.

Choose the right GPU mode

Olares provides three GPU modes, each designed for a different usage pattern.

GPU mode	Definition	Use scenario
Time slicing (Default)	Multiple apps share one GPU by taking turns using compute and VRAM.	General workloads that run several lightweight apps.
App exclusive	One app gets full, uninterrupted access to the compute and VRAM of a single GPU.	Heavy workloads that require maximum stability, such as LLMs and high‑end gaming.
Memory slicing	The GPU's VRAM is divided into fixed quotas, and apps run concurrently within their limits.	Running specific apps simultaneously while strictly limiting their memory usage.

View GPU details

Go to Settings > GPU to view your GPU status and current mode.

TIP

If you have more than one GPU, Olares lists all your GPUs on this page. Just click a GPU to open its details page directly.

Switch GPU mode

Follow these steps to change how a GPU is used:

1. Go to Settings > GPU.
2. Choose a mode from the GPU mode dropdown.

Restart notice

Changing a GPU's mode restarts applications currently using that GPU.

Time slicing

Time slicing is the default mode in Olares. Use this mode to allow multiple applications to share resources.

When a GPU is in Time slicing mode, GPU-enabled applications are automatically assigned to it. These applications will appear in the app list on this page.

App exclusive

Use App exclusive mode to dedicate a GPU entirely to one high-demand application.

Bind app

To give an app exclusive access:

1. In Select exclusive app section, click Bind app.
2. Select your target application and click Confirm.

Switch app

To replace the current exclusive app with a new one:

1. In Select exclusive app section, click Switch app.
2. Choose the new application and click Confirm.

The previous app is unbound, and the new app takes over exclusive access.

Unbind app

To remove the exclusive binding:

1. In Select exclusive app section, click link_off.
2. In the pop-up window, click Confirm to unbind the app from the GPU.

Memory slicing

Use Memory slicing to run apps concurrently with strict VRAM limits.

Bind app and allocate VRAM

1. In Allocate VRAM section, click Bind app.
2. Select your target application, assign it a specific amount of VRAM in GB, and click Confirm.

   WARNING

   The total of all VRAM limits must not exceed the GPU total VRAM.

3. Repeat for other apps as needed.
