pub fn fp8_quant_hopper_lane(tid: u32, span: u32) -> Option<(u32, u32, u32)>Expand description
2026-09-25: The group slot thread tid of a Hopper CTA works on, and the
half-open range [start, end) of 8 elements it owns within that
128-element group, as sub/lane in the .cu. None when the slot is
past the CTA’s span.
