Hello,
Do I have to adapt the CUDA code to use NVlink?
In other words,
If I have CUDA code that working on 1 GPU and I add more GPUs that connected with NVlink, do I need to change my code?
Thank you,
Artium.

Your code developed to use a single GPU won’t automatically use more than one GPU just because they are connected with NVLink. Yes, code changes are needed.
Thank you for your response,
where can I find tutorial that explain what I need to do ?
just search on multi-GPU
the cuda simple multi-GPU sample code
