The authors better start thinking about the trademark infringement notice coming their way
Naming anything is hard and I don’t have better suggestions but when you’re doing something that’s already poking at something a big corp holds dearly hitting on trademark while you’re at it makes it really easy for them.
You can't have the CUDA substring in the name or anything a court would deem potentially confusing. Even if "CUDA" wasn't registered, using a similar name could be seen as an attempt to pass off the product as affiliated with or endorsed by NVIDIA. The similarity in names could be construed as an attempt to unfairly benefit from NVIDIA's reputation and market position. If the open-source project implements techniques or methods patented by NVIDIA for CUDA, it could face patent infringement claims. If CUDA is considered a famous mark, using a similar name could be seen as diluting its distinctiveness, even if the products aren't directly competing. If domain names similar to CUDA-related domains are registered for the project, this could potentially lead to domain dispute issues. It's a huge can of worms.
