Role::WholeDenoiser is the denoise network exported with any height and
width, for a whole frame instead of 1408 tiles whose borders are thrown
away. It is served only where a new size costs nothing: the CUDA
provider, and TensorRT through an optimisation profile from 256 to
4608 x 6656, tuned for the 6D's frame with Best's border. Everywhere
else whole_frame_limit() says None and the fixed tiles run.
ort's TensorRT builder has no profile options, so the engine registers
through the runtime's V2 options with the names 1.30 reads
(trt_profile_{min,opt,max}_shapes). Without a profile a dynamic input
compiled an engine per size at run time, 156 s on the first frame. The
engine lives in its own directory per model: ORT's cache key leaves the
shape out, and the fixed 1408 export and its any-size sibling are the
same graph.
