Driver Incompatibility for Supporting Both Volta and Blackwell Simultaneously on Ubuntu

Accelerated Computing CUDA CUDA Setup and Installation

Hello NVIDIA team and community,

I’m currently facing a driver compatibility issue on Ubuntu when trying to support both Volta-based GPUs (Tesla V100) and the latest Blackwell GPUs (RTX 5090) in the same system(on Ubuntu LTS 24.04 and Supermicro H12ssl-i).

From my testing, V100s are supported by the proprietary NVIDIA drivers. However, my RTX5090 requires the open-source NVIDIA GPU kernel modules and is not supported by the proprietary drivers. This creates a dead end for my plan to combine V100’s FP64 jobs and RTX5090’s FP8 jobs in the same workstation.

Is there any release of a unified driver branch that supports both Volta and Blackwell architectures at the same time? If not, what is the recommended best practice for systems that require both GPUs to be operational simultaneously under Ubuntu/Linux? Will there be containerized or multi-driver solutions officially supported for such mixed setups?

Thank you for your time, and I look forward to any guidance or roadmap information.

Regards,

Zhiyuan
