Why is matlab not using GPU for deep learning, even though it says that it is?

Hi Tanmay,
I understand that you are trying to train a deep learning model in MATLAB using GPU, but MATLAB is not utilizing the GPU effectively despite displaying that it is training on a single GPU.
This issue may arise due to multiple factors, such as GPU compatibility, execution settings, or memory limitations.
Please consider the following workarounds to enable utilization of the GPU:
- Run “gpuDevice” to ensure your GPU is CUDA-enabled and compatible with MATLAB. Verify GPU drivers and CUDA/cuDNN toolkit installation.
- Run the following command to explicitly use GPU:
options = trainingOptions('sgdm', 'ExecutionEnvironment', 'gpu');
- GPU Detection: Run “gpuDevice”. If not detected, restart MATLAB and reinstall CUDA/cuDNN.
- Increase batch size in “trainingOptions” to optimize GPU usage.
- Ensure the “Parallel Computing Toolbox” is installed for GPU support.
- Use “nvidia-smi” (Windows) or “watch -n 1 nvidia-smi” (Linux) to check GPU activity.
For further reference, kindly check MATLAB’s official GPU support documentation:
Cheers & Happy Coding!
