Unnecessary __syncthreads

Open JohnSully opened this issue 4 years ago • 1 comments

Forgive me if I'm missing something, but reading the code the __syncthreads in ComputeKeys appears to be unnecessary as I don't see any x-thread communication. Each thread appears to be reading from it's own index in the startx/starty arrays. I do see a decent performance bump if these are removed.

What is the purpose of the __syncthreads call here?

JohnSully, hi dear, have you compiled without this function? Can I check it?
