Summary of Changes

Hello @saara-tyagi27, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces a change to how the NVIDIA Data Center GPU Manager (DCGM) packages are managed within the A3 Ultra GPU Slurm blueprint. The primary goal is to ensure stability and reproducibility by explicitly pinning the DCGM version and preventing automatic updates, which is crucial for maintaining consistent environments, especially in machine learning setups.

Highlights

• DCGM Version Pinning: The datacenter-gpu-manager (DCGM) packages are now explicitly installed with version 1:4.5.0-1 in the a3ultra-slurm-blueprint.yaml configuration.
• Package Holding: After installation, the datacenter-gpu-manager-4-cuda12, datacenter-gpu-manager-4-dev, and datacenter-gpu-manager-4-core packages are marked to be held, preventing unintended automatic upgrades.

Changelog

• examples/machine-learning/a3-ultragpu-8g/a3ultra-slurm-blueprint.yaml
  • Modified the installation process for datacenter-gpu-manager packages to specify version 1:4.5.0-1.
  • Added apt-mark hold commands to prevent future automatic upgrades of the DCGM packages.

Code Review

This pull request pins the version of DCGM packages to ensure stability, which is a good practice. My review focuses on improving the maintainability of the installation script by consolidating commands and removing commented-out code, aligning with guidelines for keeping inline scripts concise.

[gemini-code-assist]

The script for installing CUDA and DCGM can be made more concise and readable. The commented-out lines should be removed, and the apt install commands can be consolidated into a single command. Additionally, the comment for apt-mark hold could be more descriptive. This improves maintainability by reducing redundancy and clarifying the script's intent.

          apt install -y \
              cuda-toolkit-12-8 \
              datacenter-gpu-manager-4-cuda12=1:4.5.0-1 \
              datacenter-gpu-manager-4-dev=1:4.5.0-1 \
              datacenter-gpu-manager-4-core=1:4.5.0-1

          # Hold DCGM components to prevent unintended upgrades
          apt-mark hold \
              datacenter-gpu-manager-4-cuda12 \
              datacenter-gpu-manager-4-dev \
              datacenter-gpu-manager-4-core

References

1. Per the style guide (line 6), code should be maintainable. Consolidating the package installation into a single apt install command and removing the commented-out code improves readability and makes the script easier to modify in the future. ^(link)
2. Per Rule: Inline shell scripts within YAML configurations are acceptable for minor, declarative additions. Making this script more concise and readable helps ensure it remains minor and declarative, aligning with the guideline to keep inline scripts manageable.
