Recent Polaris HPCM upgrades to the OS, libfabric, and CUDA represent major changes and may break compatibility with older versions. Users are strongly encouraged to recompile code to avoid issues. Please note the correct CUDA versions post the HPCM upgrade:

• NVIDIA driver version (565.57.01) (CUDA driver API 12.7 – previously listed incorrectly as CUDA 12.9)
• Default base nvidia-hpc_sdk is now at 24.11 (CUDA toolkit 12.6 – previously listed incorrectly as CUDA 12.9)
