How to Safely Eject a GPU (with examples)

The SafeEjectGPU command is a utility that allows users to safely eject a GPU on their system. This command provides various use cases to manage and control GPUs attached to the system.

Use case 1: Eject all GPUs

Code:

SafeEjectGPU Eject

Motivation:

• This use case is useful when you want to eject all the GPUs attached to your system at once, ensuring that they are safely disconnected.

Explanation:

• SafeEjectGPU: The command used to safely eject GPUs.
• Eject: The argument specifying that all GPUs should be ejected.

Example output:

Ejecting all GPUs...
GPU 0 ejected successfully.
GPU 1 ejected successfully.
...

Use case 2: List all GPUs attached

Code:

SafeEjectGPU gpus

Motivation:

• You may want to quickly check which GPUs are currently attached to your system before performing any other actions.

Explanation:

• SafeEjectGPU: The command used to safely eject GPUs.
• gpus: The argument specifying that you want to list all GPUs attached.

Example output:

GPU 0: NVIDIA GeForce RTX 3070
GPU 1: AMD Radeon RX 6800 XT
...

Use case 3: List apps using a GPU

Code:

SafeEjectGPU gpuid GPU_ID apps

Motivation:

• It can be helpful to identify which apps are currently using a specific GPU before ejecting it.

Explanation:

• SafeEjectGPU: The command used to safely eject GPUs.
• gpuid: The argument specifying that you want to list apps using a particular GPU.
• GPU_ID: The ID of the GPU for which you want to list the apps.
• apps: The argument specifying that you want to list the apps using the specified GPU.

Example output:

Apps using GPU 0:
- Safari.app
- Final Cut Pro.app
...

Apps using GPU 1:
- Chrome.app
- Adobe Photoshop.app
...

Use case 4: Get the status of a GPU

Code:

SafeEjectGPU gpuid GPU_ID status

Motivation:

• You may need to check the current status of a specific GPU, such as whether it is in use or idle, before performing any actions on it.

Explanation:

• SafeEjectGPU: The command used to safely eject GPUs.
• gpuid: The argument specifying that you want to get the status of a particular GPU.
• GPU_ID: The ID of the GPU for which you want to get the status.
• status: The argument specifying that you want to retrieve the status of the specified GPU.

Example output:

Status of GPU 0: Idle
Status of GPU 1: In use
...

Use case 5: Eject a GPU

Code:

SafeEjectGPU gpuid GPU_ID Eject

Motivation:

• You can use this use case to safely eject a specific GPU from your system without affecting other GPUs.

Explanation:

• SafeEjectGPU: The command used to safely eject GPUs.
• gpuid: The argument specifying that you want to eject a particular GPU.
• GPU_ID: The ID of the GPU that you want to eject.
• Eject: The argument specifying that you want to eject the specified GPU.

Example output:

Ejecting GPU 1...
GPU 1 ejected successfully.

Use case 6: Launch an app on a GPU

Code:

SafeEjectGPU gpuid GPU_ID LaunchOnGPU path/to/App.app

Motivation:

• This use case allows you to launch a specific app directly on a chosen GPU, useful for testing or troubleshooting purposes.

Explanation:

• SafeEjectGPU: The command used to safely eject GPUs.
• gpuid: The argument specifying that you want to launch an app on a particular GPU.
• GPU_ID: The ID of the GPU on which you want to launch the app.
• LaunchOnGPU: The argument specifying that you want to launch an app on the specified GPU.
• path/to/App.app: The path to the application bundle (.app) that you want to launch on the specified GPU.

Example output:

Launching "App.app" on GPU 0...
"App.app" launched successfully on GPU 0.

Conclusion:

The SafeEjectGPU command provides a versatile set of use cases to safely manage and control GPUs attached to your system. Whether you want to eject all GPUs, list attached GPUs, identify apps using a GPU, get the status of a GPU, eject a specific GPU, or launch an app on a GPU, this command offers the necessary functionality for efficient GPU management.
