C is not CLOSE TO THE METAL. It lacks concept of SIMD instructions and barriers/fences. If you want to be CTM learn OpenCL / CUDA (unless you want to learn assembler for actual ISAs or SIMD extensions).

Thanks for spelling it out, I am surprised there are people in this year and age who would not get that "C is close to the metal" is a trite joke.
