GPU Power Limit Manager

This bash script, named gpu_power_limit.sh, provides tools to manage the power limits of NVIDIA GPUs. It allows you to set, reset, or display power limits for all connected GPUs.

Installation

1. Clone the Repository:

   git clone <your-repository-url> gpu_power_limit
   cd gpu_power_limit
   

2. Make the Script Executable:

   chmod +x gpu_power_limit.sh

Usage

The script accepts the following commands:

• Set Power Limit:

  ./gpu_power_limit.sh set <limit|percentage%>

• limit: A numeric value in watts (e.g., 300).

• percentage%: A percentage reduction from the default limit (e.g., 15%).

• Reset Power Limit:

  ./gpu_power_limit.sh reset

This command resets the power limit of all GPUs to their default values.

• Print Power Limits:

  ./gpu_power_limit.sh print

Displays the current, maximum, and minimum power limits for all GPUs.

Examples

• Set power limit to 250 watts for all GPUs:

  ./gpu_power_limit.sh set 250

• Reduce power limit by 10% for all GPUs:

  ./gpu_power_limit.sh set 10%

• Reset all GPUs to their default power limits:

  ./gpu_power_limit.sh reset

• Check current power limits:

  ./gpu_power_limit.sh print

Requirements

• NVIDIA GPUs with support for nvidia-smi command.
• Bash shell.

Notes

• Ensure you have the necessary permissions to adjust GPU settings. You might need to run the script with sudo if you encounter permission issues.
• The script checks if the new power limit is above the GPU's minimum power limit to prevent setting values too low for stable operation.
