# MLCDevice

An object that represents the CPU or one or more GPUs the framework uses to execute a neural network.

```
class MLCDevice
```

## Topics

### Creating Devices

[`init(type:)`](/documentation/MLCompute/MLCDevice/init(type:))

Creates a device of the type you specify.

[`init(type:selectsMultipleComputeDevices:)`](/documentation/MLCompute/MLCDevice/init(type:selectsMultipleComputeDevices:))

Creates a device that you can configure to use multiple compute devices.

[`MLCDeviceType`](/documentation/MLCompute/MLCDeviceType)

A device type for execution of a neural network.

[`init(gpuDevices:)`](/documentation/MLCompute/MLCDevice/init(gpuDevices:)-4mj85)

Creates a device using the GPUs you specify.

[`cpu()`](/documentation/MLCompute/MLCDevice/cpu())

Creates a device that uses the CPU.

[`gpu()`](/documentation/MLCompute/MLCDevice/gpu())

Creates a device that uses a GPU, if one exists.

[`ane()`](/documentation/MLCompute/MLCDevice/ane())

Creates a device that uses the Apple Neural Engine, if one exists.

### Inspecting Devices

[`type`](/documentation/MLCompute/MLCDevice/type)

The type you specify when creating the device.

[`actualDeviceType`](/documentation/MLCompute/MLCDevice/actualDeviceType)

The active device.

[`gpuDevices`](/documentation/MLCompute/MLCDevice/gpuDevices)

An array that contains the specific Metal devices you use to execute neural networks.
