dq BLOCK_N2=64 + split-timing diagnostic for bwd d=128 non-causal
-
Fix bwd register spill at d=128 (num_warps=8) and trackio per-point logging
-
Fix benchmark: q/k/v requires_grad for backward timing
-
Fix test harness: reference grads via .backward() (autograd.grad result was discarded)
-
Fix: dkdv backward uses tl.dot(k, qT) with untransposed K (shape bug)
-
Fix: pass tl dtypes as DTYPE constexpr (triton 3.8 rejects torch.dtype in .to())
-
Fix: constexpr globals for triton 3.8 (RCP_LN2, LN2)
-
FlashAttention-2 Triton reproduction script (fwd+bwd, tests, benchmark)
