NVIDIA RTX 6000 Ada 48 GB 4DP Graphics compatibility with CUDA 11.X

Hi, we just purchased a new machine with NVIDIA RTX 6000 Ada 48 GB 4DP Graphics card and CUDA 12 running on the machine. Unfortunately we have an application looking for CUDA 11.X and are unable to run this with CUDA 12. Can anybody advise on if it is possible to run this card with CUDA 11/ if I can revert CUDA to an older version?

I’m assuming a linux OS here, although the comments apply to Windows as well.

you should be able to use CUDA 11.8 in a normal fashion with your RTX 6000 Ada GPUs. If you already have CUDA 12 installed and running properly, there is no need to install a new or different driver for CUDA 11.8. You still may need to install the CUDA toolkit components minus the driver, and both the package manager and runfile install methods allow for this.

For package manager method, the package you would specify is ... install cuda-toolkit-11-8
For a runfile installer method, the runfile installer will present you with an install menu. Deselect the option to install the driver.

in other respects, follow the instructions in the linked guide for post-install steps including setting PATH variable.

If you wish to use a software stack installed via e.g. conda, then there are methods to select a cuda version with those, usually.

I don’t recommend trying to use something prior to CUDA 11.8
