Hotfix: Update G4 NVIDIA drivers for kernel 6.17 compatibility

  • Update NVIDIA driver branch from 575 to 590 to support the newer 6.17.0-1008-gcp kernel in recent Ubuntu 24.04 LTS images.
  • Resolve dpkg file conflicts by adding a task to remove the pre-installed Ubuntu 'nvidia-firmware-590' package.
  • Use 'force-overwrite' dpkg option to ensure NVIDIA repository firmware correctly replaces conflicting system files.
  • Correct package naming to 'nvidia-driver-590-open' to align with NVIDIA's current repository conventions for open kernel modules.
  • Set CUDA toolkit to 12.8 for stable compatibility with the 590 branch.

Callouts:
The issue being fixed here can re-occur if the image and package versions are not pinned.

Code Review

This pull request updates the NVIDIA drivers in the ml-slurm-g4.yaml example to version 590, likely to ensure compatibility with newer kernels. The changes include updating the list of nvidia_packages, adding a task to remove a conflicting firmware package, and using force-overwrite during the driver installation. While the updates seem reasonable, I have a concern regarding the use of force-overwrite. It's a powerful option that can reduce system robustness and maintainability. I've added a comment suggesting to either explore alternatives or to improve the in-code documentation to better justify its use, which would align with the project's goals for technical excellence and maintainability.
