6ca294ed6d D5a: Use tensor indexing for LSE write 2026-05-23 21:13:52 +00:00
7e91d76669 D5a: Use cute.store for LSE write 2026-05-23 21:13:07 +00:00
751abd9b18 D5a: Fix LSE - compute row_max_safe from final row_max, remove mLSE None check 2026-05-23 21:12:29 +00:00
d6ea7f3ebd D5a: Fix - add normalize param to __init__ 2026-05-23 21:11:37 +00:00
c80f223d08 D5a: Add normalize flag + LSE output
- normalize=True (default): O = softmax(P) @ V (existing behavior)
- normalize=False: O = P @ V (un-normalized) + lse = log(row_sum) + row_max
- LSE tensor passed as optional parameter
- Test includes D5a normalize=False verification with LSE comparison
- Cleaned up SMEM-P debug prints and broken make_tiled_copy_C code
- hd=64 TMEM-P regression: cos 0.973 PASS

542bc7b1b0 D1.3: Use const_expr if for tOrP0 compile-time selection 2026-05-23 21:07:58 +00:00
37edd783ce D1.3: Pre-compute tOrP0_offset in _setup, use const_expr for compile-time selection 2026-05-23 21:07:10 +00:00
972fbd48b9 D1.3: Use const_expr for tOrP0 offset (compile-time conditional) 2026-05-23 21:06:16 +00:00
a762820352 D1.3: Use MLIR-compatible expression for tOrP0 offset (same as Stage C) 2026-05-23 21:05:12 +00:00
4fa4239f95 D1.3: Initialize tOrP0 before conditional for CuTeDSL scoping 2026-05-23 21:03:53 +00:00
2bb3eb95ed D1.3: Fix tOrP0 for SMEM-P - skip make_tensor when offset is 0
CuTeDSL doesn't support OpResult + int. When offset is 0 (SMEM-P),
just use tOrP directly.

eabea91b64 D1.3: Fix tOrP0 offset - scale FP32 columns to BF16 elements
tmem_p0_offset is in FP32 columns, but tOrP uses BF16 elements.
Offset = p0_offset * (32/16) = p0_offset * 2.

47eade4afc D1.3: Fix CuTeDSL scoping - define tOrP0 unconditionally with p0 offset 2026-05-23 21:01:18 +00:00
0e81fc18aa D1.3: Fix critical bug - add TMEM column offset for P0 in PV GEMM
The softmax warps store P at tmem_p0_offset=32. PV MMA must read from
the same offset. tOrP0 was missing the offset, causing PV to read from
TMEM column 0 (where S is) instead of column 32 (where P is).
This was the root cause of NaN/zeros in D1 tests.

8bc8b21470 D1.3: Full correction_epilog with TMA store, normalize in reg before SMEM write
One-way trip: TMEM->reg (normalize) ->SMEM->GMEM
Replicates epilogue_tma_store logic with normalize step added
Uses CUTLASS helpers for correct layout handling

d769e01a16 D1.3: Apply transform_partitioned_tensor_layout before epilogue helpers 2026-05-23 20:52:42 +00:00
cc18fddc7e D1.3: Replace NO-op TMEM round-trip with correction_epilog using epilogue_tmem_copy_and_partition + epilogue_smem_copy_and_partition
- Remove hand-constructed TMEM round-trips (3% layout mismatch error)
- Use CUTLASS get_tmem_load_op + get_smem_store_op paired atoms
- One-way trip: TMEM -> reg (normalize) -> SMEM -> GMEM
- SMEM-P path: zero-fill stub (proper copy TBD)
- Keep per-tile O rescale atoms for n>128 support
