I’d like to use some SDK samples kernels for my app. The kernels need to be adjusted to work with floating point inputs, but I am concerned if I can use code based on the NVIDIA samples at all.
Eg, for the matrix transpose sample I read

Interestingly the same matrix transpose sample from the OpenCL SDK has a much more relaxed copyright note

So, is NVIDIA heading to the more relaxed copyright of OpenCL for CUDA stuff soon, or do I have to ask for a written permission to use & modify the CUDA sample code.
These copyright’s do not exactly help to widespread the use of efficient code on NVIDIA GPUs.
