So there > is no additional H2D cost at each call, right? Yes, this environment is a constant fed into the kernel at compile time. It will allow us to pass more information, e.g., if you want to support sequentialiazed parallel regions, in a way that caused the "feature" to be removed during compilation. It also allows us to communicate dynamic information in a way that will make us pay for it only if we "enable" it, e.g., if you don't want printf support on AMDGPU you don't have to pay for a buffer.
