For CUDA specifically, there is a fairly large set of sample code that used to be installed when you installed CUDA. But now I think it’s on the Nvidia GitHub page; you’ve got to download it yourself.

The Nvidia dev blog has some easy to follow tutorials, but they don’t get very complicated.

Nvidia also has a learning platform which offers fairly decent courses at a cost. You get a certificate for finishing.

You’ll find some books out there with good reputations. Ultimately, this is an area that leans heavily toward paying money for good quality learning materials.

The best course by NVidia looks like "Fundamentals of Accelerated Computing with CUDA C/C++" which I think used to be publicly available, but is now offered "By invitation only"

It appears as though that course has been replaced with "Getting Started with Accelerated Computing in CUDA C/C++" which is $90 as a self-paced online class with a certificate at the end.

The course you are referring to is instructor-led and costs $10,000 to have them set up, for up to 20 people.
