cuTile implementations for group_norm, kl_div, llama4_rope, qwen2vl_mrope, rope, sparsemax, tiled_mlp, and multi_token_attention, dispatched via LIGER_KERNEL_IMPL=cutile. Includes three-way (liger_triton / liger_cutile / torch|huggingface) speed+memory benchmark data on B200 generated with the open-source pip nvidia-cuda-tileiras 13.3.36. Notable kernel choices: - rope/qwen2vl_mrope: stay in input dtype, drop redundant .contiguous() copies - kl_div: drop scale constexpr to avoid per-iter JIT recompile - group_norm: fp32 stats for numerical parity - multi_token_attention: conv-backward runs under the same cuDNN heuristic as the Triton path (no forced cudnn.benchmark) for apples-to-apples comparison Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
