How to Check GPU Usage on Ubuntu

Are you experiencing sluggish performance or suspecting your GPU is not being utilized effectively on your Ubuntu system? Monitoring GPU usage is crucial for understanding your system's resource allocation and troubleshooting potential performance issues. This article will guide you through various methods to check your GPU usage on Ubuntu.

1. Using the nvidia-smi Command

For users with Nvidia GPUs, the nvidia-smi command is your go-to tool for GPU monitoring. This command provides a comprehensive overview of your GPU's utilization, temperature, memory usage, and other vital information.

Here's how to use it:

  1. Open a terminal window.
  2. Type nvidia-smi and press Enter.

The output will display a table with the following information:

  • GPU Name: The model of your Nvidia GPU.
  • GPU ID: The unique ID of your GPU.
  • Memory.Usage: The amount of GPU memory currently in use.
  • Utilization.Gpu: The percentage of your GPU's processing power currently being used.
  • Temperature.Gpu: The temperature of your GPU.
  • Fan.Speed: The speed of your GPU's fan.

Example:

+-----------------------------------------------------------------------------+
| NVIDIA-SMI 470.57.02   Driver Version: 470.57.02   CUDA Version: 11.4     |
|-------------------------------+----------------------+----------------------+
| GPU  Name        Persistence-M| Bus-Id        Disp.A | Volatile Uncorr. ECC |
| Fan  Temp   Perf  Pwr:Usage/Cap|         Memory-Usage | GPU-Util  Compute M. |
|===============================+======================+======================|
| 0  GeForce GTX 1080    On   | 00000000:01:00.0  On   |                  0 |
| N/A   42C    P8    17W / 250W |  1375MiB / 8192MiB |    15%      Default |
+-------------------------------+----------------------+----------------------+

Understanding the Output:

In this example, the output shows that the GeForce GTX 1080 GPU is currently using 15% of its processing power, 1375MB of its 8GB memory, and has a temperature of 42 degrees Celsius.

2. Using gpustat Command

gpustat is another powerful command-line tool that offers detailed GPU usage statistics. It provides a continuous stream of data on your GPU's utilization, memory, temperature, and other metrics.

To install gpustat:

  1. Open a terminal window.
  2. Run the following command: sudo apt install gpustat

Once installed, you can use it by typing:

gpustat

This will display a table with the following information:

  • GPU Name: The model of your GPU.
  • Memory.Total: The total amount of GPU memory.
  • Memory.Used: The amount of GPU memory currently in use.
  • Utilization.Gpu: The percentage of your GPU's processing power currently being used.
  • Temperature.Gpu: The temperature of your GPU.

Example:

-------------------------------------------------------------------------------
GPU     |   Load |  Memory.Total |  Memory.Used |  Memory.Free |     Temp | Utilization |
-------------------------------------------------------------------------------
 GeForce GTX 1080 |    15% |     8192 MB |    1375 MB |    6817 MB |    42 C |       15% |
-------------------------------------------------------------------------------

gpustat can also be used to monitor multiple GPUs if you have a multi-GPU system.

3. Using System Monitoring Tools

Several system monitoring tools are available for Ubuntu, providing visual dashboards with GPU usage information.

  • GNOME System Monitor: Built-in to GNOME desktop environments, it provides a graphical interface for monitoring CPU, RAM, and GPU usage. To access it, search for "System Monitor" in the Applications Menu.
  • Htop: A powerful command-line process viewer, it can display real-time GPU usage alongside other system statistics. To install it, run sudo apt install htop in a terminal.
  • Conky: A highly customizable system monitoring utility, it can display various system metrics including GPU usage. You can find pre-configured Conky themes online or create your own.

These tools offer a user-friendly interface for monitoring your GPU's performance.

4. Using GPU-Specific Monitoring Software

For specific GPU manufacturers like Nvidia and AMD, dedicated software is available that provides more in-depth GPU monitoring and control.

  • Nvidia Control Panel: Accessible from the system tray on Ubuntu, it provides a graphical interface for configuring GPU settings and viewing performance metrics.
  • AMD Radeon Software: Available for AMD GPUs, it offers a comprehensive suite of tools for GPU monitoring, driver updates, and performance optimization.

These software packages often provide more features and granular control over your GPU's performance.

Troubleshooting Performance Issues with GPU Usage

Once you have a clear understanding of your GPU's usage, you can troubleshoot potential performance issues.

Common Scenarios:

  • High GPU Usage, But Low Frame Rates: This could indicate a bottleneck elsewhere in your system, such as a CPU or RAM limitation.
  • Low GPU Usage, But Slow Performance: Your GPU may not be adequately utilized due to driver issues, software conflicts, or resource allocation problems.

Tips for Optimizing GPU Usage:

  • Update Drivers: Ensure you have the latest GPU drivers installed for optimal performance.
  • Close Unnecessary Programs: Minimize background processes and applications that may be using GPU resources.
  • Adjust Graphics Settings: Reduce graphics settings in games or applications to lower GPU demands.
  • Monitor GPU Temperature: Overheating can cause performance degradation. Ensure adequate cooling for your GPU.
  • Check for Driver Conflicts: Conflicts between drivers or software can affect GPU performance.

Conclusion

Monitoring your GPU usage on Ubuntu is essential for understanding your system's performance and troubleshooting any issues. By utilizing the command-line tools, system monitoring utilities, or GPU-specific software discussed in this article, you can gain insights into your GPU's utilization and make informed decisions to optimize its performance. Remember to keep your drivers updated and ensure adequate cooling for your GPU to maintain optimal performance.
