…#2757) * [Common] Fix linker error for to_string(DType) in distributed tests Make transformer_engine::to_string(DType) inline in common.h so that translation units outside libtransformer_engine.so can resolve it without requiring the symbol to be exported. Regression introduced by 61f9594 which added to_string(DType) calls into TRANSFORMER_ENGINE_TYPE_SWITCH_* macros, causing test object files to reference the symbol that the linker version script hides.

Signed-off-by: Pawel Gadzinski <pgadzinski@nvidia.com> Made-with: Cursor * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * fix: use detach().clone() to avoid shared storage in DumpTensors Using tensor.detach() creates a view sharing the same underlying storage. If any in-place operation modifies the tensor after the dump, the saved data would be silently corrupted. Use .clone() to ensure the dump captures an independent copy of the data. Signed-off-by: Pawel Gadzinski <pgadzinski@nvidia.com> * test: use torch.equal instead of torch.allclose for serialisation round-trip The saved tensor is an exact bit-for-bit copy (detach().clone()), so torch.equal is the correct check. torch.allclose with its default tolerances could mask a genuine dtype conversion or precision loss introduced by a future change to the serialisation path.

Add tests that demonstrate two known memory issues with FSDP2 + FP8:
- Issue #2681: FP8 weight copies created during te.autocast() forward pass
accumulate across layers instead of being freed between layers, defeating
FSDP2's memory efficiency. Detected by comparing per-layer forward memory
increments against a bf16 baseline using layer hooks.
- Issue #2717: Transpose cache tensors (_create_transpose) allocated during
backward persist until the next forward pass instead of being freed after
backward completes. Detected by comparing the backward memory delta
(post_bwd - post_fwd) against a bf16 baseline.
New tests:
- test_bf16_no_excess_forward_memory: control, validates per-layer measurement
- test_bf16_no_excess_backward_memory: control, validates backward delta comparison
- test_fp8_temp_accumulation_across_layers: xfail, detects #2681
- test_transpose_cache_retained_after_backward: xfail, detects #2717
All parametrized over 5 FP8 recipes x {no_quant_init, quant_init}.

Fix three issues: - Read "rowwise_data" attribute instead of "data" to get the flat 1D quantized buffer rather than torch.Tensor.data (2D wrapper). - Use quantizer->dtype (e.g. kFloat8E4M3) instead of deriving dtype from the raw tensor's scalar_type() which is just uint8. - Pass numel() as a 1-element shape vector to ensure the grouped tensor data is registered as 1D. Promote DType dtype from quantizer subclasses to the base Quantizer class (defaulting to kNumTypes) so group_dequantize can access it without downcasting.

Audit of cleanly-merged upstream changes revealed three issues: 1. newton_schulz/newton_schulz.cpp: added to cuda_only_cpp_sources in CMakeLists.txt — includes cuda_runtime.h directly, uses cuSolverMp, not hipifiable as a .cpp file. 2. pytorch/csrc/extensions/newton_schulz.cpp: wrapped in #ifndef USE_ROCM guard — calls at::cuda::getCurrentCUDAStream() and cuSolverMp APIs. 3. pytorch/__init__.py: guarded newton_schulz import with IS_HIP_EXTENSION check — tex.newton_schulz pybind binding is not registered on ROCm. Co-Authored-By: Claude Sonnet 4 <noreply@anthropic.com>
Seven build errors resolved: 1. cast/core/common.cuh: restructured __HIP_PLATFORM_AMD__ guards — TensorMapStorage, g_tensor_maps, and TMA helper functions guarded; kernel namespace (reduce_dbias, grouped_reduce_dbias) and block decode helpers left unguarded for ROCm use; new upstream TMA dispatch functions (modify_base_tensor_map, update_tma_descriptors, prefetch/store_output_stage) guarded separately. 2. cast/mxfp8/group_dequantize_mxfp8.cuh: entire file guarded with #ifndef __HIP_PLATFORM_AMD__ — uses CUtensorMap throughout. 3. cast/dispatch/dequantize.cuh: guard MXFP8 group_dequantize call with #ifndef __HIP_PLATFORM_AMD__ — depends on group_dequantize_mxfp8.cuh. 4. util/ptx.cuh: added non-template float exp2f_rcp(e8m0_t) overload under #ifdef __HIP_PLATFORM_AMD__ — ROCm-specific files call without <float> template arg. Moved BF16_MANTISSA_BITS outside the CUDA-only guard so ROCm exp2f_rcp<bf16> works. 5. fused_router/utils.h: changed __ballot_sync mask from unsigned int to uint64_t and switched to __popcll — HIP requires 64-bit ballot mask. 6. normalization/rmsnorm/rmsnorm_api.cpp: guarded use_cudnn_norm_bwd() / NVTE_Norm_Backend::Cudnn / use_zero_centered_gamma_in_weight_dtype() calls with #ifndef __HIP_PLATFORM_AMD__. 7. pytorch/csrc/quantizer.cpp: removed duplicate eligible_for_rht_cast_fusion declaration; fixed columnwise_quant_config → columnwise_quant_config_to_use; added out_transpose wrapper construction for the RHT unfused columnwise path. 8. pytorch/quantization.py: added missing `import functools`. Co-Authored-By: Claude Sonnet 4 <noreply@anthropic.com>
Resolved API mismatch from Phase 1 conflict resolution where upstream refactored _Linear.forward to receive quantizers as separate args instead of packed in non_tensor_args: 1. Updated _Linear.forward signature to accept 6 quantizer args separately matching the new call convention from Linear.forward. 2. Updated non_tensor_args unpacking to match the new tuple format (no quantizers). 3. Added ctx.save_for_backward and ctx.tensor_objects assignment. 4. Added ctx.backward_override initialization. 5. Fixed _Linear.backward return to reshape dgrad via ctx.inp_shape and return 11 None-padded values matching the new 11-arg forward signature. 6. Added import of restore_from_saved. 7. Added import functools to quantization.py. Co-Authored-By: Claude Sonnet 4 <noreply@anthropic.com>
…de ordering Two fixes in _Linear.forward: 1. non_tensor_args at call site incorrectly passed 'cache_name is not None' (bool) at the 'module' position — changed to pass 'self' (the Linear module object). 2. backward_override nullification of ctx fields was placed before the ctx assignments, causing them to be immediately overwritten — moved to run after all ctx fields are set. Co-Authored-By: Claude Sonnet 4 <noreply@anthropic.com>
Two build fixes: 1. tests/cpp/operator/test_normalization.cu: guard cudnnGetVersion() call with #ifndef __HIP_PLATFORM_AMD__ — cuDNN is not available on ROCm and use_cudnn is always false on this platform. 2. transformer_engine/jax/csrc/extensions/gemm.cpp: fix GroupedGemmV2Handler FFI binding — replace individual .Attr<> entries (M, N, K, lhs_is_trans, rhs_is_trans, scaling_mode, is_grouped_dense_wgrad) with .Attrs<GroupedGemmV2Config>() to match the GroupedGemmV2FFI function signature. This was the Phase 1 conflict resolution error where the old attribute-based registration was kept instead of adopting the upstream struct-based API.

Two copyright-header issues here, both inconsistent with the convention used in every other ROCm-modified file in this PR (see e.g. transformer_engine/jax/cpp_extensions/quantization.py, transformer_engine/pytorch/module/linear.py):
- Order is reversed. Per CLAUDE.md, when an existing NVIDIA-only file gains an AMD line, the AMD line must go above the NVIDIA line.
- Missing the
# This file was modified for portability to AMDGPUmarker line that every other ROCm-touched Python file carries above the AMD copyright.

The newly added import on line 15 re-imports the same three symbols already imported on line 14 (all_files_in_dir, get_cuda_include_dirs, debug_build_enabled). Looks like a leftover from the merge conflict resolution — both sides of the conflict were kept rather than being unified into a single import (compare with build_tools/pytorch.py, where the equivalent conflict was correctly merged into one from .utils import (...) block).
It works at runtime, but please consolidate to avoid the duplicate, e.g.:

Let's explicitly disable FA3 and FA4 for ROCm
Fixes for FSDP2 distributed tests on ROCm:
1. run_fsdp2_fused_adam.py:
- Add IS_HIP_EXTENSION import and AIPYTORCH-427 synchronize() after
loss.backward() and optimizer.step() in all training loops to prevent
RCCL deadlocks from forward/backward stream overlap with FSDP2.
- Add synchronize() in test_fuse_wgrad_accumulation after forward pass.
- xfail NVFP4BlockScaling in test_fused_adam_bf16 and
test_fused_adam_bf16_store_param_remainders on ROCm: RCCL
allreduce_coalesced on NVFP4 amax tensors produces incorrect values,
causing scale_inv = inf and NaN outputs. Confirmed by disable_rht=True
workaround which bypasses the amax all-reduce path.
2. run_fsdp2_model.py:
- Add IS_HIP_EXTENSION import and AIPYTORCH-427 synchronize() after
backward() in training loop (matches existing pattern from dev branch).
- Fix double dist.destroy_process_group() from keep_both merge: barrier
(for torch < 2.6 teardown race) and destroy consolidated into finally.
- xfail NVFP4BlockScaling + fp8_init + LayerNormLinear on ROCm:
_check_fp8_fsdp2_allgather exceeds atol=5e-4 due to per-shard amax
divergence between the FSDP2 unshard path and manual allgather path.
3. test_torch_fsdp2.py:
- Fix NameError 'fp8' not defined: replaced deprecated fp8 module
references with direct imports from quantization module.
- Add _get_free_port() and --master_port to torchrun calls to prevent
EADDRINUSE when tests run sequentially.
- xfail NVFP4BlockScaling + fp8_init + LayerNormLinear on ROCm.
4. test_cast_master_weights_to_fp8.py:
- Skip _test_cast_master_weights_to_nvfp4 on ROCm: same NVFP4 amax
RCCL issue causes NaN loss; assert_close(nan, nan) then fails
because NaN != NaN by IEEE 754.
