pub const MAX_DECODE_SPLITS: u32 = 16;Expand description
2026-09-25: Ceiling on the split count under every policy but Legacy,
and so on the split-K workspace, which is
rows * num_q_heads * num_splits * (head_dim + 2) F32 values. Without it
a model with few q heads would ask for 2 * sm_count / num_q_heads splits
(264 for one head on 132 SMs). At 24 q heads on the 148-SM targets
(kernels/b200, kernels/b300) auto asks for 13. A pinned count is
clamped to it.
