# GPUDeviceID

Media Server can use a graphics card (GPU) to significantly increase the speed of some types of training and analysis. To use a GPU by default, set this parameter to the device ID of the GPU to use.

You can override the value of this parameter for individual actions by setting the `GPUDeviceID` action parameter (on actions that support a GPU). You can override the value of this parameter for individual analysis tasks by setting `GPUDeviceID` in the task configuration.

You can find the device ID for each graphics card using the Nvidia SMI tool.

The default value of this parameter is `CPU`, which disables GPU acceleration.

TIP: Several requirements must be met before you can use a GPU. For information about how to use a GPU with Media Server, see Enable GPU Acceleration. Media Server does not start if you enable GPU support but the server has no GPU, or the requirements for using the GPU have not been met.
