After long drought, I got one:

65077 *2^3605944+1 is prime!

This removes a k from the S16 search. Many thanks to Gary for helping to get this posted at the top 5000 primes site. ...and everything else he does for the CRUS project.

Not just any GPU. It has to be an OpenCL GPU, right? Doesn't that generally mean AMD GPU?

OpenCL is supported on NVIDIA and AMD GPUs as long as you have a driver for it. CUDA is NVIDIA specific.
