I'm out of my depth but I believe it's a torus because it's 2 cylinders, not circles?

You are completely right, I'll mention this in the post (In that case do a branchless comparison based on subtraction or similar?). Fwiw when doing simd, you'd use intrinsics which wouldn't have this issue, but it is a valid

Here's a godbolt to play with as well, showing how it does actually compile down to being branchless in clang (you can switch it to use other compilers too) https://goo.gl/bywp8b

This isn't a parallelized implementation, no. To have that, imagine that instead of a size_t for ret, that it was something like size_t[4], and that each operation you did acted on all 4 items at once (this is how SIMD operations work

If you tried the demo and were remarkably unimpressed, give it a try again and it ought to work better (make sure and manually refresh - F5 so you don't have the old page cached). I read how the MNIST data was generated and followed su
