The (maybe imperfect) solution is to mask out the Python keys for guard comparisons. This might be fine because custom dispatch modes won't appear here during compilation - `ignore_compile_internals=True` hides them, and `ignore_compile_internals=False` disables compile entirely?

It must be possible to trace this - fused kernel directly into the graph for fidelity with eager (NB: a user - has the option of then further decomposing at proxy tensor mode via - decomposition table, but we must preserve it to proxy mode to have the - choice.) - - Why does functionalization need to also perform the test here? This is - because some CompositeImplicitAutograd decompositions are not functional. - If we are eventually going to decompose, we need to do this while we can - still turn functionalization back on, so those decompositions get functionalized. - So an early decomposition in functionalization may still be necessary. Note that - if proxy tensor decomposition process could turn functionalization back on, this - wouldn't be necessary, and maybe that is a useful thing to do anyway because - the decomposition table is user specified and a user could violate the functional - decomp requirement with a bad decomp. If this happened, then you could always - pass through functionalization. - """ - has_backend_registration = False - for a in flat_args: - if isinstance(a, torch.Tensor): - backend_key = torch._C._parse_dispatch_key( - torch._C._dispatch_key_for_device(a.device.type) - ) - assert backend_key is not None - # TODO: use func.has_kernel_for_dispatch_key(backend_key) - # but this one checks py_impl and CompositeImplicitAutograd - # incorrectly shows up as has backend reg here - has_backend_registration = torch._C._dispatch_has_kernel_for_dispatch_key( - func.name(), backend_key - ) - - # in theory we should take all backend keys and take the highest priority one - # to properly mimic the dispatcher, - # this just grabs the first tensor and takes its device key - break - return not has_backend_registration - - # See NOTE[SchemaInfo int_tags] above. _TORCH_TAG_INPLACE_VIEW_INT = int(torch.Tag.inplace_view) # type: ignore[call-overload] diff --git a/torchgen/gen_functionalization_type.py b/torchgen/gen_functionalization_type.py index 1cb681ba19d3..c396941cf913 100644 --- a/torchgen/gen_functionalization_type.py +++ b/torchgen/gen_functionalization_type.py @@ -1024,22 +1024,8 @@ def gen_functionalization_registration( ) -> list[str]: @with_native_function def emit_registration_helper(f: NativeFunction) -> str: - if f.has_composite_implicit_autograd_kernel: - metadata = composite_implicit_autograd_index.get_kernel(f) - assert metadata is not None - native_api_name = metadata.kernel - sig = NativeSignature(f.func, symint=metadata.supports_symint()) - # Note [Composite view ops in the functionalization pass] - # We don't need to worry about implemententing functionalization kernels for views with - # CompositeImplicitAutograd kernels, because we can just decompose them into their base operators. - # We can't just opt the entire Functionalization dispatch key into the composite keyset though, - # because we don't want to decompose non-view ops that are composite, like `at::ones`. - registration_str = ( - f"static_cast<{sig.ptr_type()}>(at::native::{native_api_name})" - ) - else: - # non-composite view ops (and inplace ops) get a normal registration. - registration_str = f"TORCH_FN(functionalization::{wrapper_name(f.func)})" + assert not f.has_composite_implicit_autograd_kernel + registration_str = f"TORCH_FN(functionalization::{wrapper_name(f.func)})" return f'm.impl("{f.func.name}", {registration_str});' # Don't generate kernels in mobile build @@ -1052,8 +1038,12 @@ def gen_functionalization_registration( if str(g.view.func.name) == "lift_fresh": return [] view_str = [] - view_str.append(emit_registration_helper(g.view)) - if g.view_inplace is not None: + if not g.view.has_composite_implicit_autograd_kernel: + view_str.append(emit_registration_helper(g.view)) + if ( + g.view_inplace is not None + and not g.view_inplace.has_composite_implicit_autograd_kernel + ): assert g.view_inplace.is_view_op view_str.append(emit_registration_helper(g.view_inplace)) return view_str From 4f8a986b8feb4a171b8a68a2a3664275ec54a75f Mon Sep 17 00:00:00 2001 From: Rahul Agrawal Date: Fri, 10 Oct 2025 20:22:07 +0000 Subject: [PATCH 012/405] Make LOCK_TIMEOUT in codecache configurable (#165030) - Introduce file_lock_timeout in config (defaults to current value of 600) - Use the above config instead of hardcoded 600 config.

We move the steps to get OIDC-based credentials from `_rocm-test.yml` to `setup-rocm.yml`. This lays the groundwork to enable access to AWS ECR in workflows in other repos such as torchtitan that use [linux_job_v2.yml](https://github.com/pytorch/test-infra/blob/main/.github/workflows/linux_job_v2.yml), which also uses [setup-rocm.yml](https://github.com/pytorch/test-infra/blob/335f4f80a0d7534a50ccc89414134b0cec8e2f3d/.github/workflows/linux_job_v2.yml#L168). Any caller workflows that eventually execute `setup-rocm` action will thus need to provide the `id-token: write` permission.

we update to include cases where we know symbolic expression is statically one. There are two errors here; first in graph capture, where a tensor with size 0 yet symbolic stride would attempt to keep the symbolic stride, resulting in a mismatch. The second is in inductor code gen, where we only checked in squeeze if size == 1, missing the case where a symbolic stride equals 1.

This change augments reporting to tensor attributes from configured set. This feature is intended to be used to ease understanding debug string when dealing with larger outputs. For example, before running forward pass of a model we can annotate each of parameters and buffers with their fully qualified names, so that we can see which ops are being executed against specific tensors.

You also need to pass a unique name that maps to the type. ```python class OpaqueQueue: def __init__(self, queue: list[torch.Tensor], init_tensor_: torch.Tensor) -> None: super().__init__() self.queue = queue self.init_tensor_ = init_tensor_ def push(self, tensor: torch.Tensor) -> None: self.queue.append(tensor) def pop(self) -> torch.Tensor: if len(self.queue) > 0: return self.queue.pop(0) return self.init_tensor_ def size(self) -> int: return len(self.queue) register_opaque_type(OpaqueQueue, "_TestOpaqueObject_OpaqueQueue") ``` When creating the custom op, the schema will then use the unique name: ```python self.lib = torch.library.Library("_TestOpaqueObject", "FRAGMENT") torch.library.define( "_TestOpaqueObject::queue_push", "(_TestOpaqueObject_OpaqueQueue a, Tensor b) -> ()", tags=torch.Tag.pt2_compliant_tag, lib=self.lib, ) @torch.library.impl( "_TestOpaqueObject::queue_push", "CompositeExplicitAutograd", lib=self.lib ) def push_impl(queue: OpaqueQueue, b: torch.Tensor) -> None: assert isinstance(queue, OpaqueQueue) queue.push(b) ``` Using the custom op: ```python queue = OpaqueQueue([], torch.zeros(3)) torch.ops._TestOpaqueObject.queue_push(queue, torch.ones(3)) self.assertTrue(queue.size(), 1) ``` Pull Request resolved: https://github.com/pytorch/pytorch/pull/165004 Approved by: https://github.com/albanD --- test/test_opaque_obj_v2.py | 84 +++++++++++++++++++ torch/_C/__init__.pyi.in | 2 + torch/_library/infer_schema.py | 12 ++- torch/_library/opaque_object.py | 35 +++++++- .../csrc/jit/frontend/schema_type_parser.cpp | 25 ++++++ torch/csrc/jit/frontend/schema_type_parser.h | 3 + torch/csrc/jit/python/init.cpp | 13 +++ 7 files changed, 170 insertions(+), 4 deletions(-) create mode 100644 test/test_opaque_obj_v2.py diff --git a/test/test_opaque_obj_v2.py b/test/test_opaque_obj_v2.py new file mode 100644 index 000000000000..aea2441c61b9 --- /dev/null +++ b/test/test_opaque_obj_v2.py @@ -0,0 +1,84 @@ +# Owner(s): ["module: custom-operators"] + +import torch +from torch._dynamo.test_case import run_tests, TestCase +from torch._library.opaque_object import register_opaque_type + + +class OpaqueQueue: + def __init__(self, queue: list[torch.Tensor], init_tensor_: torch.Tensor) -> None: + super().__init__() + self.queue = queue + self.init_tensor_ = init_tensor_ + + def push(self, tensor: torch.Tensor) -> None: + self.queue.append(tensor) + + def pop(self) -> torch.Tensor: + if len(self.queue) > 0: + return self.queue.pop(0) + return self.init_tensor_ + + def size(self) -> int: + return len(self.queue) + + +class TestOpaqueObject(TestCase): + def setUp(self): + self.lib = torch.library.Library("_TestOpaqueObject", "FRAGMENT") #

Unfortunately, all of these approaches have their own composability issues with different techniques. **Candidate Approaches** 1. Ask users to write a module to wrap FlexAttention/SDPA and use `parallelize_module` to install a forward hook. - Pros: This is similar to how we do TP. - Cons: 1) It is cumbersome for users as they need to create a new module. 2) We need two places to parallelize the CP, as a context_parallel context manager is still required for splitting the inputs. 2. Provide a function wrapper. - Pros: Users just need to replace their FlexAttention/SDPA calls with the wrapper. - Cons: It is not the same API, though we can maintain the API signatures to be the same as the core API. **Summary** ~~This PR implements approach 2 and refactor the code in such a way that most code can be used by option approach 1, which will be introduced in another PR.~~ We changed this PR to implement option 1 as people like option 1 due to the consistency with the existing parallelisms. But this PR can also serve the foundation to implement option 2, which was the early version of this PR. This PR also changes `create_cp_block_mask` logic since we now only focus on ModuleWrapper approach which doesn't require to hack the seq_len field in a BlockMask. This PR also removes TorchFunctionMode dispatcher mode as it doesn't work well with SAC.

Yang" Date: Fri, 10 Oct 2025 13:25:49 -0700 Subject: [PATCH 028/405] Do not decompose in functionalization/proxy tensor if autograd wouldn't have decomposed (#164939) This fixes AOTAutograd rms_norm not being bitwise equivalent to eager, because it avoids a decomposition. You can force the decomposition by having the decomposition in the dispatch table, but if eager mode wouldn't have decomposed (because it went to the fused one), we now default to preserving the fused call by default. This largely reverts https://github.com/pytorch/pytorch/pull/103275/ for view ops. This means that in inference mode we could hit the wrong C++ kernel; if this occurs we should just SymInt'ify the C++ kernel. Another neat side effect of this change is that Inductor's generated kernels for rms_norm now have rms_norm in their name. Signed-off-by: Edward Z.

As of now, we just rely on the string `compile_with_inductor` and ignore the integer. As the needs arise, we can update the logic. Example ``` def fn(x, y): sin = torch.sin(x) with fx_traceback.annotate({"compile_with_inductor": 0}): mul = sin * y add = mul + 1 return torch.sin(add) ``` 2) You have to instruct the compiler to use the annotations with `compile_fx_annotated_nodes_with_inductor` transformation. This is somewhat controversial, and a user might expect that just setting annotation is enough. But for now to control the blast radius, we need to explicitly do this. One such example is ``` # Set the fw and bw compiler of aot_autograd to `compile_fx_annotated_nodes_with_inductor` def aot_eager_regional_inductor(): return aot_autograd( fw_compiler=compile_fx_annotated_nodes_with_inductor, bw_compiler=compile_fx_annotated_nodes_with_inductor, ) ``` 3) Fixable in short-term - You have to wrap the user code in `torch.fx.traceback.preserve_node_meta` to ensure that annotations are propagated to the compiler. This is fixable, just need to make CI happy. ### Implementation 1) Relies on `CapabilityBasedPartitioner` to "scoop" out regions based on annotations, and then create subgraphs in the main graph. 2) Call `torch._inductor.standalone_compile` on these subgraphs, and jam the returned callable into the FX graph at the place of call_module Resulting graph looks something like this - search for `torch__inductor_standalone_compile_inner` Forward graph ``` class GraphModule(torch.nn.Module): def forward(self, primals_1: "f32[10]", primals_2: "f32[10]"): # File: /data/users/anijain/pytorch2/test/dynamo/test_regional_inductor.py:64 in fn, code: sin = torch.sin(x) sin: "f32[10]" = torch.ops.aten.sin.default(primals_1) # No stacktrace found for following nodes inner = torch__inductor_standalone_compile_inner(sin, primals_2) # File: /data/users/anijain/pytorch2/test/dynamo/test_regional_inductor.py:68 in fn, code: add = mul + 1 getitem: "f32[10]" = inner[0]; inner = None # File: /data/users/anijain/pytorch2/test/dynamo/test_regional_inductor.py:70 in fn, code: return torch.sin(add) sin_1: "f32[10]" = torch.ops.aten.sin.default(getitem) return (sin_1, primals_1, primals_2, sin, getitem) ``` Backward graph ``` class GraphModule(torch.nn.Module): def forward(self, primals_1: "f32[10]", primals_2: "f32[10]", sin: "f32[10]", add: "f32[10]", tangents_1: "f32[10]"): # File: /data/users/anijain/pytorch2/test/dynamo/test_regional_inductor.py:64 in fn, code: sin = torch.sin(x) cos_1: "f32[10]" = torch.ops.aten.cos.default(primals_1); primals_1 = None # File: /data/users/anijain/pytorch2/test/dynamo/test_regional_inductor.py:70 in fn, code: return torch.sin(add) cos: "f32[10]" = torch.ops.aten.cos.default(add); add = None mul_1: "f32[10]" = torch.ops.aten.mul.Tensor(tangents_1, cos); tangents_1 = cos = None # No stacktrace found for following nodes inner = torch__inductor_standalone_compile_inner(mul_1, sin, primals_2); mul_1 = sin = primals_2 = None # File: /data/users/anijain/pytorch2/test/dynamo/test_regional_inductor.py:67 in fn, code: mul = sin * y getitem: "f32[10]" = inner[0] getitem_1: "f32[10]" = inner[1]; inner = None # File: /data/users/anijain/pytorch2/test/dynamo/test_regional_inductor.py:64 in fn, code: sin = torch.sin(x) mul_4: "f32[10]" = torch.ops.aten.mul.Tensor(getitem_1, cos_1); getitem_1 = cos_1 = None return (mul_4, getitem) ``` ### Some issue raised in the HOP meeting 1) CSE will not differentiate different meta custom nodes and do wrong thing. 2) SAC - The recomputed forward will be smaller than the forward. Will we compile a smaller region than? 3) What happens if you have a op in the middle which does not disturb the topology, is it still 1 subgraph? 4) What happens with the nesting of `fx_traceback.annotate`? Are there any ordering requirements? 5) What are we going to use the annotations for? a) compile flex b) streams c) nn.Module info to organize MoE components for pipelining d) PP stages e) Rename graph nodes for more debugging f) No nested regional compile Pull Request resolved: https://github.com/pytorch/pytorch/pull/164776 Approved by: https://github.com/SherlockNoMad --- docs/source/conf.py | 2 + docs/source/fx.md | 1 + test/dynamo/test_regional_inductor.py | 295 ++++++++++++++++++ .../_functorch/_aot_autograd/graph_compile.py | 2 + torch/fx/passes/__init__.py | 1 + torch/fx/passes/regional_inductor.py | 133 ++++++++ 6 files changed, 434 insertions(+) create mode 100644 test/dynamo/test_regional_inductor.py create mode 100644 torch/fx/passes/regional_inductor.py diff --git a/docs/source/conf.py b/docs/source/conf.py index 9c6a43e9227f..70ea74ae86b4 100644 --- a/docs/source/conf.py +++ b/docs/source/conf.py @@ -1081,6 +1081,8 @@ coverage_ignore_functions = [ "loop_pass", "these_before_those_pass_constraint", "this_before_that_pass_constraint", + # torch.fx.passes.regional_inductor + "regional_inductor", # torch.fx.passes.reinplace "reinplace", # torch.fx.passes.split_module diff --git a/docs/source/fx.md b/docs/source/fx.md index 8baa9589d1ac..c9c235382893 100644 --- a/docs/source/fx.md +++ b/docs/source/fx.md @@ -1169,6 +1169,7 @@ The set of leaf modules can be customized by overriding .. py:module:: torch.fx.passes.operator_support .. py:module:: torch.fx.passes.param_fetch .. py:module:: torch.fx.passes.pass_manager +.. py:module:: torch.fx.passes.regional_inductor .. py:module:: torch.fx.passes.reinplace .. py:module:: torch.fx.passes.runtime_assert .. py:module:: torch.fx.passes.shape_prop diff --git a/test/dynamo/test_regional_inductor.py b/test/dynamo/test_regional_inductor.py new file mode 100644 index 000000000000..21c7cda5754e --- /dev/null +++ b/test/dynamo/test_regional_inductor.py @@ -0,0 +1,295 @@ +# Owner(s): ["module: dynamo"] + +import functools + +import torch +import torch._inductor.test_case +import torch.fx.traceback as fx_traceback +import torch.utils.checkpoint +from torch._dynamo.backends.common import aot_autograd +from torch._inductor.test_case import run_tests +from torch._inductor.utils import run_fw_bw_and_get_code +from torch.fx.passes.regional_inductor import regional_inductor +from torch.nn.attention.flex_attention import create_block_mask, flex_attention +from torch.testing._internal.common_utils import skipIfTorchDynamo +from torch.testing._internal.triton_utils import requires_cuda_and_triton + + +# Open questions / follow-ups +# 1) CSE behavior with meta custom nodes +# Common subexpression elimination may not differentiate between distinct meta +# custom nodes and could remove expressions, which might confuse users. +# +# 2) SAC: recompute vs. forward size +# If the recomputed forward is smaller than the original forward, do we end up +# compiling only the smaller region? +# +# 3) fx_traceback.annotate nesting +# How does nesting behave?

Compare it with the saved result. - Do the above again in deterministic mode. I tried to test a few modes - BertForMaskedLM and GoogleFnet: I can repro the numeric change by distorting the benchnmark result in the default mode. The non-determinism is gone in the deterministic mode - DistillGPT2: I can not repro the numeric change by distorting the benchmarking result in the default mode. It does not surprise me much.

A LocalTensor might be size N, but in fact there are world_size shards/replicas of it stored internally. When you do a plain PyTorch operation on it, we apply the operation to each shard; when you do a collective, we do the mathematically equivalent operation on the local shards. A LocalTensor is associated with a list of ranks which specify which ranks it holds local tensors for. NB, this is NOT a DataParallel like abstraction where you can run operations on multiple different GPUs. It is intended purely for *debugging* purposes, the overhead is almost certainly too high to keep eight GPUs (even the C++ autograd needs multithreading to keep up!) (It might potentially be possible to trace through this with torch.compile and then compile it with CUDA graphs but this is currently a non-goal.) In order to handle MPMD, we provide a helper decorator that allows you to run a function with no side effects for each LocalTensor shard and combine results back into LocalTensor or LocalIntNode. Note: This PR convert all DTensor ops and some DTensor tests to illustrate intended usage and ensure conrrectness. In subsequent PR more tests will be converted. DUring test conversion we aim to share as much as possible of test logic between multi-process / multi-threaded and local tensor tests. We would like to developers to be able to run both flavors of the tests. Note: This work is based on the original proposal by @ezyang (WIP PR https://github.com/pytorch/pytorch/pull/162753).

Call + + +""" +A LocalTensor is a tensor subclass which simulates a tensor that is +distributed across SPMD ranks. A LocalTensor might be size N, but in fact +there are world_size shards/replicas of it stored internally. When you do a +plain PyTorch operation on it, we apply the operation to each shard; when you +do a collective, we do the mathematically equivalent operation on the local +shards. A LocalTensor is associated with a list of ranks which specify +which ranks it holds local tensors for. + +NB, this is NOT a DataParallel like abstraction where you can run operations +on multiple different GPUs. It is intended purely for *debugging* purposes, +the overhead is almost certainly too high to keep eight GPUs (even the C++ +autograd needs multithreading to keep up!) (It might potentially be possible +to trace through this with torch.compile and then compile it with CUDA graphs +but this is currently a non-goal.) + +We do not directly handling MPMD. However in practice even in SPMD you may +encounter divergence in behavior per rank (for example, uneven sharding +across ranks). To support scenarios like this, we provide a helper decorator +that allows you to run a function with no side effects for each LocalTensor +shard and combine results back into LocalTensor or LocalIntNode. + +NB: This is a torch dispatch Tensor subclass, as we want to assume that autograd +is SPMD, so we run it once, and dispatch the inner autograd calls to the individual +local shards. + +NOTE ABOUT MESH: This subclass requires collectives that are issued to it to +respect a DeviceMesh like abstraction. The reason for this is that when +DTensor issues us a collective for a particular rank, you will be asked to do +this on a specific process group which involves some ranks. However, this +will only be for the LOCAL PG that this particular rank is participating in; +there will be a bunch of other PGs for other nodes that you don't get to see. +We need to be able to reverse engineer all of the collectives that don't +involve the current local rank here to actually issue them. This can be done +two ways: (1) looking at the participating local ranks in the PG and computing +the complement which specifies all the other collectives you have to run, or +(2) retrieving the device mesh axis corresponding to the PG for this rank, and +then running all the fibers for this. +""" + +import contextlib +import functools +import operator +import os +import sys +from collections import defaultdict +from collections.abc import Sequence +from types import TracebackType +from typing import Any, Callable, Generator, Optional, Union + +import torch +from torch import Size, SymBool, SymInt, Tensor +from torch._C import DispatchKey, DispatchKeySet +from torch._export.wrappers import mark_subclass_constructor_exportable_experimental +from torch.distributed import DeviceMesh +from torch.distributed._functional_collectives import AsyncCollectiveTensor +from torch.fx.experimental._constant_symnode import ConstantIntNode +from torch.nested._internal.nested_int import NestedIntNode +from torch.utils import _pytree as pytree +from torch.utils._python_dispatch import return_and_correct_aliasing, TorchDispatchMode +from torch.utils.checkpoint import get_device_states, set_device_states + + +not_implemented_log = torch._logging.getArtifactLogger(__name__, "not_implemented") + + +from . import _c10d + + +def _int_on_rank(i: "LocalIntNode | ConstantIntNode", r: int) -> int: + if isinstance(i, LocalIntNode): + return i._local_ints[r] + elif isinstance(i, ConstantIntNode): + return i.val + else: + raise AssertionError(type(i)) + + +def _check_for_subclass(flat_args: Sequence[object]) -> bool: + return any(_check_for_subclass_arg(x) for x in flat_args) + + +def _check_for_subclass_arg(x: object) -> bool: + return ( + not isinstance(x, LocalTensor) + and isinstance(x, Tensor) + and type(x) not in (Tensor, torch.nn.Parameter, torch.nn.Buffer) + ) + + +def _map_to_rank_local_val(val: Any, rank: int) -> Any: + if isinstance(val, LocalTensor): + return val._local_tensors[rank] + if isinstance(val, SymInt) and isinstance(val.node, LocalIntNode): + return val.node._local_ints[rank] + return val + + +def _for_each_rank_run_func( + func: Callable[..., Any], + ranks: frozenset[int], + args: Sequence[Any], + kwargs: dict[str, Any], + *, + alias: bool = True, +) -> Any: + flat_args, args_spec = pytree.tree_flatten((args, kwargs)) + + cpu_state = torch.get_rng_state() + devices, states = get_device_states((args, kwargs)) + + flat_rank_rets = {} + + for r in sorted(ranks): + torch.set_rng_state(cpu_state) + set_device_states(devices, states) + rank_flat_args = [_map_to_rank_local_val(a, r) for a in flat_args] + rank_args, rank_kwargs = pytree.tree_unflatten(rank_flat_args, args_spec) + rank_ret = func(*rank_args, **rank_kwargs) + flat_rank_rets[r] = rank_ret + + rr_key = next(iter(flat_rank_rets.keys())) + rr_val = flat_rank_rets[rr_key] + + if isinstance(rr_val, Tensor): + ret = LocalTensor({r: flat_rank_rets[r] for r in sorted(ranks)}) + elif isinstance(rr_val, (list, tuple)): + ret_list = [] + for i in range(len(rr_val)): + rets = {r: flat_rank_rets[r][i] for r in sorted(ranks)} + v_it = iter(rets.values()) + v = next(v_it) + if isinstance(v, Tensor): + ret_list.append(LocalTensor(rets)) + elif isinstance(v, int) and not all(v == v2 for v2 in v_it): + ret_list.append(torch.SymInt(LocalIntNode(rets))) + else: + assert all(v == v2 for v2 in v_it) + ret_list.append(v) + ret = type(rr_val)(ret_list) + else: + v_it = iter(flat_rank_rets.values()) + v = next(v_it) + if all(v == v2 for v2 in v_it): + return v + if isinstance(v, int): + return torch.SymInt(LocalIntNode(flat_rank_rets)) + raise AssertionError(f"Unexpected return type {type(v)}") + + if alias: + return return_and_correct_aliasing(func, args, kwargs, ret) + else: + return ret + + +def _get_extra_dispatch_keys(t: torch.Tensor) -> DispatchKeySet: + extra_dispatch_keys = torch._C.DispatchKeySet.from_raw_repr(0) + if torch._C._dispatch_keys(t).has(torch._C.DispatchKey.Conjugate): + extra_dispatch_keys = extra_dispatch_keys.add(torch._C.DispatchKey.Conjugate) + if torch._C._dispatch_keys(t).has(torch._C.DispatchKey.Negative): + extra_dispatch_keys = extra_dispatch_keys.add(torch._C.DispatchKey.Negative) + return extra_dispatch_keys + + +class LocalIntNode: + """ + Like a LocalTensor, but for an int.

Now that we plan to redesign CP's UX to explicitly ask users to: 1. Wrap the attention op into an `nn.Module` 2. Lift any buffers that are not sequence agnostic to input We can replace `context_parallel()` with two functional APIs: `_context_parallel_shard` and `_enable_context_parallel_dispatcher`.

But BlockMask actually has B=1 case that the BlockMask will be broadcast. This PR adds the support of B=1 case. 2. The original split_args_kwargs_into_chunks doesn't initialize the default specs correctly. Since we now use tree_flatten and tree_unflatten to do split, we should also use tree_map to initialize the default spec. This will actually support the case when the values are not torch.Tensor, which were only supported if users explicitly provide the shard spec.

Build a graph to search for the path from source placement to destination placement (with device order). Currently solution introduces too many all-gathers and missing the opportunity for all-to-all when redistribute, especially when we consider the device order. ### How to build the graph: When operator of Shard, think of collective op as operation on a stack of device axis: - I, J are tensor dimensions; - X, Y, Z, Y are ordered mesh dimensions. image Detailed collective op transition is implemented in `DTensorRedistributePlanner.get_next_state`. ### How to find the min cost path: Assign weight to different type of collective ops and use Dijkstra to find the min cost path from the graph we build.

As of now, we just rely on the string `compile_with_inductor` and ignore the integer. As the needs arise, we can update the logic. Example ``` def fn(x, y): sin = torch.sin(x) with fx_traceback.annotate({"compile_with_inductor": 0}): mul = sin * y add = mul + 1 return torch.sin(add) ``` 2) You have to instruct the compiler to use the annotations with `compile_fx_annotated_nodes_with_inductor` transformation. This is somewhat controversial, and a user might expect that just setting annotation is enough. But for now to control the blast radius, we need to explicitly do this. One such example is ``` # Set the fw and bw compiler of aot_autograd to `compile_fx_annotated_nodes_with_inductor` def aot_eager_regional_inductor(): return aot_autograd( fw_compiler=compile_fx_annotated_nodes_with_inductor, bw_compiler=compile_fx_annotated_nodes_with_inductor, ) ``` 3) Fixable in short-term - You have to wrap the user code in `torch.fx.traceback.preserve_node_meta` to ensure that annotations are propagated to the compiler. This is fixable, just need to make CI happy. ### Implementation 1) Relies on `CapabilityBasedPartitioner` to "scoop" out regions based on annotations, and then create subgraphs in the main graph. 2) Call `torch._inductor.standalone_compile` on these subgraphs, and jam the returned callable into the FX graph at the place of call_module Resulting graph looks something like this - search for `torch__inductor_standalone_compile_inner` Forward graph ``` class GraphModule(torch.nn.Module): def forward(self, primals_1: "f32[10]", primals_2: "f32[10]"): # File: /data/users/anijain/pytorch2/test/dynamo/test_regional_inductor.py:64 in fn, code: sin = torch.sin(x) sin: "f32[10]" = torch.ops.aten.sin.default(primals_1) # No stacktrace found for following nodes inner = torch__inductor_standalone_compile_inner(sin, primals_2) # File: /data/users/anijain/pytorch2/test/dynamo/test_regional_inductor.py:68 in fn, code: add = mul + 1 getitem: "f32[10]" = inner[0]; inner = None # File: /data/users/anijain/pytorch2/test/dynamo/test_regional_inductor.py:70 in fn, code: return torch.sin(add) sin_1: "f32[10]" = torch.ops.aten.sin.default(getitem) return (sin_1, primals_1, primals_2, sin, getitem) ``` Backward graph ``` class GraphModule(torch.nn.Module): def forward(self, primals_1: "f32[10]", primals_2: "f32[10]", sin: "f32[10]", add: "f32[10]", tangents_1: "f32[10]"): # File: /data/users/anijain/pytorch2/test/dynamo/test_regional_inductor.py:64 in fn, code: sin = torch.sin(x) cos_1: "f32[10]" = torch.ops.aten.cos.default(primals_1); primals_1 = None # File: /data/users/anijain/pytorch2/test/dynamo/test_regional_inductor.py:70 in fn, code: return torch.sin(add) cos: "f32[10]" = torch.ops.aten.cos.default(add); add = None mul_1: "f32[10]" = torch.ops.aten.mul.Tensor(tangents_1, cos); tangents_1 = cos = None # No stacktrace found for following nodes inner = torch__inductor_standalone_compile_inner(mul_1, sin, primals_2); mul_1 = sin = primals_2 = None # File: /data/users/anijain/pytorch2/test/dynamo/test_regional_inductor.py:67 in fn, code: mul = sin * y getitem: "f32[10]" = inner[0] getitem_1: "f32[10]" = inner[1]; inner = None # File: /data/users/anijain/pytorch2/test/dynamo/test_regional_inductor.py:64 in fn, code: sin = torch.sin(x) mul_4: "f32[10]" = torch.ops.aten.mul.Tensor(getitem_1, cos_1); getitem_1 = cos_1 = None return (mul_4, getitem) ``` ### Some issue raised in the HOP meeting 1) CSE will not differentiate different meta custom nodes and do wrong thing. 2) SAC - The recomputed forward will be smaller than the forward. Will we compile a smaller region than? 3) What happens if you have a op in the middle which does not disturb the topology, is it still 1 subgraph? 4) What happens with the nesting of `fx_traceback.annotate`? Are there any ordering requirements? 5) What are we going to use the annotations for? a) compile flex b) streams c) nn.Module info to organize MoE components for pipelining d) PP stages e) Rename graph nodes for more debugging f) No nested regional compile Pull Request resolved: https://github.com/pytorch/pytorch/pull/164776 Approved by: https://github.com/SherlockNoMad ghstack dependencies: #165188 --- docs/source/conf.py | 2 + docs/source/fx.md | 1 + test/dynamo/test_regional_inductor.py | 284 ++++++++++++++++++ test/higher_order_ops/test_invoke_subgraph.py | 23 -- .../_functorch/_aot_autograd/graph_compile.py | 2 + torch/fx/passes/__init__.py | 1 + torch/fx/passes/regional_inductor.py | 133 ++++++++ 7 files changed, 423 insertions(+), 23 deletions(-) create mode 100644 test/dynamo/test_regional_inductor.py create mode 100644 torch/fx/passes/regional_inductor.py diff --git a/docs/source/conf.py b/docs/source/conf.py index 8b0571d2fed2..d21e67c1caad 100644 --- a/docs/source/conf.py +++ b/docs/source/conf.py @@ -1019,6 +1019,8 @@ coverage_ignore_functions = [ "loop_pass", "these_before_those_pass_constraint", "this_before_that_pass_constraint", + # torch.fx.passes.regional_inductor + "regional_inductor", # torch.fx.passes.reinplace "reinplace", # torch.fx.passes.split_module diff --git a/docs/source/fx.md b/docs/source/fx.md index 8baa9589d1ac..c9c235382893 100644 --- a/docs/source/fx.md +++ b/docs/source/fx.md @@ -1169,6 +1169,7 @@ The set of leaf modules can be customized by overriding .. py:module:: torch.fx.passes.operator_support .. py:module:: torch.fx.passes.param_fetch .. py:module:: torch.fx.passes.pass_manager +.. py:module:: torch.fx.passes.regional_inductor .. py:module:: torch.fx.passes.reinplace .. py:module:: torch.fx.passes.runtime_assert .. py:module:: torch.fx.passes.shape_prop diff --git a/test/dynamo/test_regional_inductor.py b/test/dynamo/test_regional_inductor.py new file mode 100644 index 000000000000..fc31e25dce3f --- /dev/null +++ b/test/dynamo/test_regional_inductor.py @@ -0,0 +1,284 @@ +# Owner(s): ["module: dynamo"] + +import functools + +import torch +import torch._inductor.test_case +import torch.fx.traceback as fx_traceback +import torch.utils.checkpoint +from torch._dynamo.backends.common import aot_autograd +from torch._inductor.test_case import run_tests +from torch._inductor.utils import run_fw_bw_and_get_code +from torch.fx.passes.regional_inductor import regional_inductor +from torch.nn.attention.flex_attention import create_block_mask, flex_attention +from torch.testing._internal.common_utils import skipIfTorchDynamo +from torch.testing._internal.triton_utils import requires_cuda_and_triton + + +# Open questions / follow-ups +# 1) CSE behavior with meta custom nodes +# Common subexpression elimination may not differentiate between distinct meta +# custom nodes and could remove expressions, which might confuse users. +# +# 2) SAC: recompute vs. forward size +# If the recomputed forward is smaller than the original forward, do we end up +# compiling only the smaller region? +# +# 3) fx_traceback.annotate nesting +# How does nesting behave?

This can cause a DDE for unbacked symints since `==` operator calls `guard_bool`. ``` // SymInt.h bool operator==(const SymInt& o) const { return sym_eq(o).guard_bool(__FILE__, __LINE__); } ``` ### Solution Adds `sym_equals()` to do elementwise equality for `SymIntArrayRef`.

To avoid complexity and ease the review process, I plan to split this work into two phases as outlined in #151705: 1. **Basic support** (this PR) 2. **Lazy broadcasting** for optimal performance (future PR) ### Summary of This PR This PR implements the basic functionality. It does **not** include lazy broadcasting, so the generated kernels may involve explicit `tl.reshape` and `tl.trans` operations before calling `tl.dot`, which introduces some overhead. ### Notable Changes 1. Adds a new config flag: `config.triton.enable_native_matmul` 2. Introduces a new `ops.dot` IR node in Inductor and lowers `aten.mm` and `aten.bmm` to it when native matmul is enabled 3. Enforces tililng suitable for matmul when the native matmul flag is enabled 4. Implements code generation for `ops.dot` 5. Adds Triton autotuning heuristics: for now, I’ve copied the configuration from the existing matmul templates. However, this may not be optimal—it currently takes a long time to tune, and I think there must be a better way to tackle this. @eellison @jansel @PaulZhang12 @shunting314 Pull Request resolved: https://github.com/pytorch/pytorch/pull/157743 Approved by: https://github.com/jansel --- .../tensor/test_dtensor_compile.py | 3 + .../test_aten_comm_compute_reordering.py | 2 + .../test_c10d_functional_native.py | 3 + .../test_compute_comm_reordering.py | 8 + test/distributed/test_dynamo_distributed.py | 4 + test/distributed/test_inductor_collectives.py | 57 +-- test/inductor/test_aot_inductor.py | 57 ++- test/inductor/test_flex_attention.py | 3 +- test/inductor/test_max_autotune.py | 100 +++- test/inductor/test_native_matmul.py | 156 ++++++ test/inductor/test_torchinductor.py | 46 +- torch/_inductor/codegen/common.py | 5 + torch/_inductor/codegen/simd.py | 118 ++++- torch/_inductor/codegen/triton.py | 472 +++++++++++++++++- torch/_inductor/config.py | 18 + torch/_inductor/dtype_propagation.py | 5 + torch/_inductor/ir.py | 47 +- torch/_inductor/kernel/bmm.py | 51 +- torch/_inductor/kernel/mm.py | 72 ++- torch/_inductor/kernel/mm_common.py | 59 +++ torch/_inductor/kernel/mm_plus_mm.py | 2 + torch/_inductor/ops_handler.py | 5 + .../runtime/coordinate_descent_tuner.py | 27 +- torch/_inductor/runtime/triton_heuristics.py | 111 +++- torch/_inductor/scheduler.py | 12 +- torch/_inductor/shape_propagation.py | 7 + 26 files changed, 1342 insertions(+), 108 deletions(-) create mode 100644 test/inductor/test_native_matmul.py diff --git a/test/distributed/tensor/test_dtensor_compile.py b/test/distributed/tensor/test_dtensor_compile.py index 6919fc93e20f..de319332af62 100644 --- a/test/distributed/tensor/test_dtensor_compile.py +++ b/test/distributed/tensor/test_dtensor_compile.py @@ -959,6 +959,9 @@ def forward(self, primals_1): out_dt = torch.matmul(tmp_dt, y_dt) out_dt.sum().backward() + @unittest.skipIf( + torch._inductor.config.triton.native_matmul, "Matmul is now generated" + ) def _test_tp_compile_comm_reordering(self): class FakeAttention(nn.Module): def __init__(self) -> None: diff --git a/test/distributed/test_aten_comm_compute_reordering.py b/test/distributed/test_aten_comm_compute_reordering.py index 080f7e3da55e..5d1a78bdae0a 100644 --- a/test/distributed/test_aten_comm_compute_reordering.py +++ b/test/distributed/test_aten_comm_compute_reordering.py @@ -64,6 +64,7 @@ def get_patches(): return { "test_configs.estimate_aten_runtime": estimate_aten_runtime, "reorder_for_locality": False, + "triton.native_matmul": False, "reorder_for_compute_comm_overlap_passes": [], "compile_threads": 1, "force_disable_caches": True, @@ -357,6 +358,7 @@ def get_bucket_patches(compute_multiplier=1.0): "test_configs.estimate_aten_runtime": estimate_aten_runtime_part, "test_configs.aten_fx_overlap_preserving_bucketing": True, "reorder_for_locality": False, + "triton.native_matmul": False, "reorder_for_compute_comm_overlap_passes": [], "compile_threads": 1, "force_disable_caches": True, diff --git a/test/distributed/test_c10d_functional_native.py b/test/distributed/test_c10d_functional_native.py index 5e9f70345ae3..0877eb53cd6f 100644 --- a/test/distributed/test_c10d_functional_native.py +++ b/test/distributed/test_c10d_functional_native.py @@ -938,6 +938,9 @@ class CompileTest(TestCase): assert "torch.ops._c10d_functional.wait_tensor.default" in code @unittest.skipIf(not HAS_GPU, "Inductor+gpu needs triton and recent GPU arch") + @unittest.skipIf( + torch._inductor.config.triton.native_matmul, "no extern_kernels.mm" + ) @fresh_cache() def test_inductor_reuse_buffer_after_inplace_collective(self): def func(arg: torch.Tensor) -> torch.Tensor: diff --git a/test/distributed/test_compute_comm_reordering.py b/test/distributed/test_compute_comm_reordering.py index 35b7a45dee7b..a13611a53609 100644 --- a/test/distributed/test_compute_comm_reordering.py +++ b/test/distributed/test_compute_comm_reordering.py @@ -78,6 +78,10 @@ def create_grouped_node_for_allreduce_and_its_deps(snodes): @requires_accelerator_dist_backend() +@unittest.skipIf( + torch._inductor.config.triton.native_matmul, + "native matmul is fused with surrounding ops", +) class TestComputeCommReorderingMultiProc(DynamoDistributedMultiProcTestCase): """ Run correctness checks in multi-proc runner, mark with minimum #

This index is generated during tracing, and at runtime, a helper function is called from the bytecode to populate this map. This differs from the previous implementation that simply mapped IDs to the associated objects. This required specialization on the IDs of the specific objects, while this new approach does not.

To avoid BC breaking changes/losing precision, we upcast the parameters to fp32 after the op gets called, and downcast the gradients to bf16 before returning. For testing, we upcast to fp32 before calling the reference function. We increase the tolerance to 1e-2 for bf16 inputs because of a difference in casting calculations between python's `x.to(torch.bfloat16)` and cpp's `x.to(at::kBFloat16)` (after comparing intermediate tensors, we found that the numerics diverge after the final casting). We don't explicitly cast in the CPP op but rather let autograd/optimizer handle it.

However, it's easy to come up with an edge case. Suppose you encounter this setup. ``` a: [s0 + u0] b: [s1 + u1] c: [u2 + u3] d: [u100] ``` Today, we use a few heuristics to specify the LHS and RHS for replacements. https://github.com/pytorch/pytorch/blob/10d2734d9b9aee767dcecaf2175d9f231810f4be/torch/_inductor/sizevars.py#L730-L759 It's possible to end up with these replacement rules. Notice how there's no replacement for `s1 + u1` and `u2 + u3` :( That's because today picking the LHS and RHS matters a lot, and `s1 + u1` & `u2 + u3` happened to end up on the RHS. ``` s0 + u0 => s1 + u1 s0 + u0 => u2 + u3 # overrides previous replacement; each expr only gets one replacement s0 + u0 => u100 # overrides previous replacement; ditto ``` I believe what we really want is this: everybody gets a replacement! And they all should (eventually) settle at the same canonical expr (i.e. `u100`) when running the replacement several times. ``` s1 + u1 ==> s0 + u0 u2 + u3 ==> s0 + u0 s0 + u0 ==> u100 ``` We can just short-cut this by using the canonical expr as the replacement. ``` s1 + u1 ==> u100 u2 + u3 ==> u100 s0 + u0 ==> u100 ``` ## Implementation I offer one way to deal with this: 1. assure every expression has one canonical replacement (i.e. `u100`) 2. if two expressions are equal (inferred from `deferred_runtime_asserts`), then they must have the same canonical replacement We can implement the above with union find. * Whenever you see `Eq(lhs, rhs)` then do `union(lhs, rhs)`. * Whenever you want to find the canonical replacement for a given expr then do `find(expr)`. * When picking the canonical replacement we can use a few heuristics like (1) prefer a fully backed expr, (2) replacing with sub-expressions, and whatever we'd like.

In flex attention, this could happen if `mask_mod` has operations (such as index) that increase the seq_nr of the forward graph nodes. Then the backward flex_attention nodes cannot find a match in its own subgraph. ``` python test/functorch/test_aot_joint_with_descriptors.py -k preserve_annotate ``` Also tested on torchtitan joint_graph_runner branch.

When we do `dist.all_gather_object`, it will create new bytestorage outside no_dispatch [here](https://github.com/pytorch/pytorch/blob/a2e2e1d8c026951baa345f0dd17668bd1718eda5/torch/distributed/distributed_c10d.py#L3303), which is on meta device. Thus, I updated the code to use `unset_fake_temporarily`, which would gather RealTensor from other ranks.

131/405] [FSDP2] provide public API to share cuda streams across roots (#165024) for pipeline parallel, we can have multiple FSDP roots (chunks) ``` model = nn.Sequential([chunk0, chunk1]) fully_shard(model.chunk0) fully_shard(model.chunk1) ``` we can call `share_comm_ctx` to share all-gather, reduce-scatter, all-reduce cuda streams. this avoids inter-stream memory fragmentation ```

As @williamwen42 suggests (https://github.com/pytorch/pytorch/pull/164349#issuecomment-3379222885) we can just for now get rid of `inspect.signature` call in flex_attention to resolve this high priority issue (https://github.com/pytorch/pytorch/issues/164247#issuecomment-3378673179). In this PR I did exactly this - limited the scope of fix to just computing `num_positional_args` in `flex_attention._get_mod_type` based on properties returned by `NestedUserFunctionVariable.const_getattr` (some were missing so I added them) Fixes #164247 Pull Request resolved: https://github.com/pytorch/pytorch/pull/164923 Approved by: https://github.com/williamwen42 --- test/dynamo/test_repros.py | 63 ++++++++++++++++++++++++++++ torch/_dynamo/variables/functions.py | 14 ++++++- torch/nn/attention/flex_attention.py | 19 ++++++--- 3 files changed, 90 insertions(+), 6 deletions(-) diff --git a/test/dynamo/test_repros.py b/test/dynamo/test_repros.py index c34c5e505e22..0fa1cbc48295 100644 --- a/test/dynamo/test_repros.py +++ b/test/dynamo/test_repros.py @@ -46,6 +46,7 @@ from torch._dynamo.backends.debugging import ExplainWithBackend from torch._dynamo.debug_utils import same_two_models from torch._dynamo.testing import ( CompileCounter, + CompileCounterWithBackend, EagerAndRecordGraphs, rand_strided, same, @@ -54,6 +55,7 @@ from torch._dynamo.testing import ( ) from torch._inductor.utils import fresh_cache from torch.nn import functional as F +from torch.nn.attention.flex_attention import create_block_mask, flex_attention from torch.profiler import profile, ProfilerActivity from torch.testing._internal.common_cuda import ( PLATFORM_SUPPORTS_FLASH_ATTENTION, @@ -7369,6 +7371,67 @@ def forward(self, s77 : torch.SymInt, s27 : torch.SymInt, L_x_ : torch.Tensor): ) self.assertEqual(explain_output.break_reasons[0].reason, expected_msg) + @parametrize("backend", ["eager", "inductor"]) + def test_issue164247(self, backend: str): + if backend == "inductor" and torch._dynamo.config.dynamic_shapes: + raise unittest.SkipTest( + "Skip only in dynamic-shapes wrapper (known issue #157612)" + ) + + class MixedFakeModeModel(nn.Module): + def __init__(self, dim=64): + super().__init__() + self.dim = dim + self.lin = torch.nn.Linear(64, 64) + + def forward(self, x): + batch_size, seq_len, _ = x.shape + + # Process input first - this creates fake tensors in export's fake mode + processed = self.lin(x) + + # Create some computation that depends on processed tensor + intermediate = processed.sum(dim=-1).detach() # Shape: (batch, seq_len) + + def dynamic_mask_function(batch_idx, head_idx, q_idx, kv_idx): + threshold = intermediate[ + batch_idx, q_idx % seq_len + ] # Access the captured tensor + return (kv_idx <= q_idx) & (threshold > 0) + + block_mask = create_block_mask( + mask_mod=dynamic_mask_function, + B=batch_size, + H=None, + Q_LEN=seq_len, + KV_LEN=seq_len, + device=x.device, + _compile=False, + ) + q = processed.view(batch_size, 1, seq_len, self.dim) + k = processed.view(batch_size, 1, seq_len, self.dim) + v = processed.view(batch_size, 1, seq_len, self.dim) + + out = torch.compile(flex_attention)(q, k, v, block_mask=block_mask) + out = flex_attention(q, k, v, block_mask=block_mask) + + return out + + backend_counter = CompileCounterWithBackend(backend) + model = MixedFakeModeModel() + compiled = torch.compile(model, backend=backend_counter, fullgraph=True) + + if backend == "inductor": + # A known InductorError Issue https://github.com/pytorch/pytorch/issues/157612 + with self.assertRaises(RuntimeError): + compiled(torch.randn(2, 128, 64)) + else: + compiled(torch.randn(2, 128, 64)) + + # One graph, so no graph breaks + self.assertEqual(backend_counter.frame_count, 1) + self.assertEqual(len(backend_counter.graphs), 1) + class ReproTestsDevice(torch._dynamo.test_case.TestCase): def test_sub_alpha_scalar_repro(self, device): diff --git a/torch/_dynamo/variables/functions.py b/torch/_dynamo/variables/functions.py index 7d534de073c9..4911ded6e333 100644 --- a/torch/_dynamo/variables/functions.py +++ b/torch/_dynamo/variables/functions.py @@ -1320,9 +1320,21 @@ class NestedUserFunctionVariable(BaseUserFunctionVariable): def const_getattr(self, tx, name): if name == "__name__": - return self.fn_name.as_python_constant() + return self.get_name() + if name == "__code__": + return self.get_code() + if name == "__defaults__": + d = getattr(self, "defaults", None) + return d.as_python_constant() if d else None return super().const_getattr(tx, name) + def call_obj_hasattr(self, tx: "InstructionTranslator", name): + if name == "__code__": + return variables.ConstantVariable.create(hasattr(self, "code")) + if name == "__defaults__": + return variables.ConstantVariable.create(hasattr(self, "defaults")) + return super().call_obj_hasattr(tx, name) + def has_self(self): return False diff --git a/torch/nn/attention/flex_attention.py b/torch/nn/attention/flex_attention.py index 27b81f49fe9c..6d44b9a5f2d9 100644 --- a/torch/nn/attention/flex_attention.py +++ b/torch/nn/attention/flex_attention.py @@ -266,11 +266,20 @@ def _get_mod_type(fn: Callable) -> _ModificationType: considered as a score_mod function.

[inductor] fix issue for example value with unbacked strides (#163660) ## Issue During autotune, we're not applying size hints atomically for the example inputs used for benchmarking. If there is unbacked symint showing up in inputs' strides, this might lead to CUDA IMA, and this could be reproduced by the added unittest, with stride being `[128 * u0, 128, 1]` and unbacked fallback being 8192, after calling `benchmark_example_value`, we get back a tensor with stride as `[8192, 128, 1]` as opposed to `[128 * 8192, 128, 1]` ## Fix Using the atomic API when trying to apply size hints to input tensor' strides.

We also want to add an explicit lower-level API that provides variable sequence length support without padding/masking in SDPA. This PR builds out `varlen_attn`, the public API that users can call for the forward method, and `_varlen_attn`, the private API that calls into the Flash Attention/cuDNN backend. **Benchmarking** To benchmark, we compare runtime and TFLOPs against the current SDPA approach with padding. Settings: - 1 H100 machine - `batch_size=8`, `max_seq_len=2048`, `embed_dim=1024`, `num_heads=16` - dtype `torch.bfloat16` - `is_causal=False` - for variable length, we set sequences to be random multiples of 64 up to `max_seq_len` - 100 runs | | Variable Length API | SDPA | |--------|--------------------|----------| | Runtime | 0.21750560760498047 ms | 0.43171775817871094 ms | | TFLOPs | 231.812 | 320.840 | The sparsity is 0.453 which we can see matches the speedup we get from Varlen (approx 50%). TFLOPs remains around the same, with SDPA slightly larger due to potential higher overhead and total flops scaling with sequence length. **Testing** Run `python test/test_varlen_attention.py` for unit tests where we verify basic functionality and confirm numerical match between varlen outputs vs SDPA. **Next steps** Next steps from this PR (higher in the stack) include registering the private API `_varlen_attn` as a custom op, implementing backward support, and enabling cuDNN with correct numerics.

With torch.compile(dynamic=True), FakeTensor + SymInt shape reasoning is used while tracing through the transform. The old vmap rule for one_hot decomposed into “zeros_symint + scatter,” which interacted poorly with the transform stack and dynamic shapes, leading to failures mid-trace. Using a functional equality construction makes one_hot composable with vmap/JVP and friendly to dynamic shape tracing. # Changes: - functorch vmap batching rule for `aten::one_hot` now uses a purely functional formulation: - Replace “zeros + scatter” with eq(self.unsqueeze(-1), arange(num_classes)).to(kLong) under FuncTorchBatched. - one_hot native path remains unchanged for regular eager; vmap transform no longer relies on scatter, which was fragile under dynamic shape tracing.

However, this change exposed a large difference in a sum for complex32. Namely the case: ``` import torch a = torch.tensor([[ 4.82031250+7.34765625j, -3.37109375-1.9501953125j], [ 3.7832031250-2.43359375j, -6.07812500+5.32812500j]], dtype=torch.complex32, device='cuda:0') sum_out = torch.sum(a) nansum_out = torch.nansum(a) torch.testing.assert_close( sum_out, nansum_out, rtol=0, atol=0, ) ``` Here, the result of `sum` and `nansum` differed significantly by 1e-2. Further investigation showed that the explicit casting of b back to `arg_t` from `scalar_t` was the root cause. `arg_t` is the dtype of the accumulator, ComplexFloat, and `scalar_t` of the input dtype, ComplexHalf. When we cast in the reduction to the accumulator order, that means the input is still of ComplexHalf, which loses precision as it can store intermediate values.

We also want to add an explicit lower-level API that provides variable sequence length support without padding/masking in SDPA. This PR builds out `varlen_attn`, the public API that users can call for the forward method, and `_varlen_attn`, the private API that calls into the Flash Attention/cuDNN backend. **Benchmarking** To benchmark, we compare runtime and TFLOPs against the current SDPA approach with padding. Settings: - 1 H100 machine - `batch_size=8`, `max_seq_len=2048`, `embed_dim=1024`, `num_heads=16` - dtype `torch.bfloat16` - `is_causal=False` - for variable length, we set sequences to be random multiples of 64 up to `max_seq_len` - 100 runs | | Variable Length API | SDPA | |--------|--------------------|----------| | Runtime | 0.21750560760498047 ms | 0.43171775817871094 ms | | TFLOPs | 231.812 | 320.840 | The sparsity is 0.453 which we can see matches the speedup we get from Varlen (approx 50%). TFLOPs remains around the same, with SDPA slightly larger due to potential higher overhead and total flops scaling with sequence length. **Testing** Run `python test/test_varlen_attention.py` for unit tests where we verify basic functionality and confirm numerical match between varlen outputs vs SDPA. **Next steps** Next steps from this PR (higher in the stack) include registering the private API `_varlen_attn` as a custom op, implementing backward support, and enabling cuDNN with correct numerics.

(I think @ezyang spotted this issue, but we have no test to capture this) Meanwhile, I notice another bug that when we normalize a `_StridedShard`'s placement, it will also trigger parent class `Shard`'s `split_tensor` method because it will create a Shard class [here](https://github.com/pytorch/pytorch/blob/0c14f55de674790fd3b2b5808de9f1a523c4feec/torch/distributed/tensor/_api.py#L783). I think we never test `distribute_tensor` for `_StridedShard` before. So I added a test here to compare against ordered shard. Using classmethod because the _split_tensor logic is different between `Shard` and `_StridedShard`. Basically I want to shard on local tensors without initializing the Shard object: ``` local_tensor = _StridedShard._make_shard_tensor(dim, tensor, mesh, mesh_dim, split_factor=split_factor) local_tensor = Shard._make_shard_tensor(dim, tensor, mesh, mesh_dim) ``` Pull Request resolved: https://github.com/pytorch/pytorch/pull/165533 Approved by: https://github.com/XilunWu --- test/distributed/tensor/test_redistribute.py | 17 ++++ torch/distributed/tensor/_api.py | 34 +++++--- torch/distributed/tensor/placement_types.py | 83 ++++++++++---------- 3 files changed, 82 insertions(+), 52 deletions(-) diff --git a/test/distributed/tensor/test_redistribute.py b/test/distributed/tensor/test_redistribute.py index 8b5d031bccfd..1eb0830422f6 100644 --- a/test/distributed/tensor/test_redistribute.py +++ b/test/distributed/tensor/test_redistribute.py @@ -20,6 +20,7 @@ from torch.distributed.tensor._collective_utils import shard_dim_alltoall from torch.distributed.tensor._dtensor_spec import ShardOrderEntry from torch.distributed.tensor._redistribute import redistribute_local_tensor from torch.distributed.tensor.debug import CommDebugMode +from torch.distributed.tensor.placement_types import _StridedShard from torch.testing._internal.common_utils import ( instantiate_parametrized_tests, parametrize, @@ -1145,6 +1146,22 @@ class DistributeWithDeviceOrderTest(DTensorTestBase): sharded_dt, mesh, tgt_placement, shard_order=None ) + @with_comms + def test_shard_order_same_data_as_strided_shard(self): + device_mesh = init_device_mesh(self.device_type, (4, 2)) + x = torch.randn(8, 4, device=self.device_type) + # specify right-to-left order use _StridedShard + strided_placement = [_StridedShard(-2, split_factor=2), Shard(-2)] + x_strided_dt = distribute_tensor(x, device_mesh, strided_placement) + # specify right-to-left order use ordered shard + x_ordered_dt = self.distribute_tensor( + x, + device_mesh, + placements=[Shard(0), Shard(0)], + shard_order=(ShardOrderEntry(tensor_dim=0, mesh_dims=(1, 0)),), + ) + self.assertEqual(x_ordered_dt.to_local(), x_strided_dt.to_local()) + if __name__ == "__main__": run_tests() diff --git a/torch/distributed/tensor/_api.py b/torch/distributed/tensor/_api.py index 03eec9c7d1d4..5fd66b2c5f8e 100644 --- a/torch/distributed/tensor/_api.py +++ b/torch/distributed/tensor/_api.py @@ -25,6 +25,7 @@ from torch.distributed.tensor._utils import ( normalize_to_torch_size, ) from torch.distributed.tensor.placement_types import ( + _StridedShard, Partial, Placement, Replicate, @@ -776,18 +777,29 @@ def distribute_tensor( # distribute the tensor according to the placements. placements = list(placements) for idx, placement in enumerate(placements): - if placement.is_shard(): - placement = cast(Shard, placement) - if placement.dim < 0: - # normalize shard placement dim - placement = Shard(placement.dim + tensor.ndim) - placements[idx] = placement - local_tensor = placement._shard_tensor( - local_tensor, device_mesh, idx, src_data_rank + if isinstance(placement, Shard): + placement_dim = ( + placement.dim + tensor.ndim if placement.dim < 0 else placement.dim ) - elif placement.is_replicate(): - placement = cast(Replicate, placement) - local_tensor = placement._replicate_tensor( + if isinstance(placement, _StridedShard): + local_tensor = _StridedShard._make_shard_tensor( + placement_dim, + local_tensor, + device_mesh, + idx, + src_data_rank, + split_factor=placement.split_factor, + ) + placements[idx] = _StridedShard( + placement_dim, split_factor=placement.split_factor + ) + else: + local_tensor = Shard._make_shard_tensor( + placement_dim, local_tensor, device_mesh, idx, src_data_rank + ) + placements[idx] = Shard(placement_dim) + elif isinstance(placement, Replicate): + local_tensor = Replicate._make_replicate_tensor( local_tensor, device_mesh, idx, src_data_rank ) else: diff --git a/torch/distributed/tensor/placement_types.py b/torch/distributed/tensor/placement_types.py index 45d8682364af..e3d17cee2eef 100644 --- a/torch/distributed/tensor/placement_types.py +++ b/torch/distributed/tensor/placement_types.py @@ -69,9 +69,8 @@ class Shard(Placement): else: return True - @staticmethod - def _make_split_tensor( - dim: int, + def _split_tensor( + self, tensor: torch.Tensor, num_chunks: int, *, @@ -87,47 +86,31 @@ class Shard(Placement): few ranks before calling the collectives (i.e. scatter/all_gather, etc.).

Did you mean: 'buf0'? ``` When not using graph partition, it would work and give the following code ([P1992997521](https://www.internalfb.com/phabricator/paste/view/P1992997521)): ``` def call(self, args): ... buf2 = buf0; del buf0 # reuse ... ``` Note that the issue is buf0 is not reused for buf2 when using graph partition. Why? Because the codegen runs `run_wrapper_ir_passes` and `memory_plan_reuse`, which pops tailing `MemoryPlanningLine` unless it is in graph output by checking `V.graph.get_output_names()`. However, for graph partition, we should check the output of the current partition instead of the graph before partition.

Account for bucketing in overlap calculation: if an in-flight collective exists with the same bucket key, reduce new collectives estimated time by its latency time - Update compute domination so we are ordering based on compute idx, as opposed to compute depth, so we never reorder compute. this makes it a bit easier to reason about memory, and pre-fetching, although we can exploring reordering in the future. - When we wait on a collective, force all collectives on the same process group as it that were enqueued prior to the collective to wait as well. Better Memory Handling: - Pre-fetch limiting - when scheduling collectives for overlap, only pre-fetch up to a certain distance, then schedule off-path collectives (which are typically memory reducing). - When we are above peak memory, schedule waits. TODO: - for each compute node, we know its original memory in the graph. we could limit pre-fetching that goes across peak memory - By scheduling off-path collectives for overlap, we reduce memory, but if there weren't enough compute for overlap, we need to proactively schedule them. not an issue yet on examples. -

The changes are from Yu-Yun . # Summary: Refactor of the implementation of the `upsample_bilinear2d_backward` opertion on MI300X/MI325X - The original "scatter-add" approach - Each thread, representing an output pixel, scattered gradient contributions to four input pixels, using costly atomic operations on MI300X/MI325X GPUs. - The new "gather-sum" approach - Each thread is responsible for a single input pixel and gathers all relevant gradient contributions from a small, calculated region of the output tensor (done by the `compute_output_range` device function). # Breakdown of the code changes - Inversion of the parallelization strategy of the kernel function `upsample_bilinear2d_backward_out_frame` - Originally, the main kernel loop was parallelized over the number of elements in the output gradient tensor (`const size_t o_numel = nc * width2 * height2;`). - Each thread processed one output pixel. - The new loop is parallelized over the number of elements in the input gradient tensor (`const size_t i_numel = nc * height1 * width1;`). - Each thread is responsible for calculating the final gradient for a single input pixel. - The kernel launch changes accordingly in the function `upsample_bilinear2d_backward_out_cuda_template`. - Added a device function for calculating the range of output pixels that could have possibly used that the input pixel (`input_pos`) during the forward pass interpolation - This is essentially the mathematical inverse of the forward pass. - This function tries to prune a thread's search space so that it only needs to inspect a small, local window of the output tensor. - Gradient calculation approach switching from "scatter-add" to "gather-sum" - Scatter-add - For each output pixel, the thread calculated 4 gradient contributions and use `fastAtomicAdd` 4 times to add these values to 4 different (and potentially highly contended) memory locations in the input gradient tensor. - Gather-sum - A thread responsible for one input pixel calls `compute_output_range` to determine the small rectangular region of output pixels that influence the input's final gradient value. - The thread iterates through this region, and for each output pixel in the regionre, it re-calculates the interpolation weights to determine the exact contribution to its specific input pixel. - All these contributions are accumulated into a private, per-thread register variable (`accscalar_t grad_sum = 0;`). - W/o any gloabl memory access, this accumulation is extremely fast. - When the loops are done, the thread performs a single, direct write (non-atomic) of the final summed gradient to its designated location in global memory (`idata[index] = static_cast(grad_sum);`). # Why performance gets boosted - Analysis of the root cause of performance drop - Ref. (internal only) - https://amd.atlassian.net/wiki/spaces/~glencao2/pages/1140493327/PyTorch__upsample_bilinear2d_backward - First and foremost, elimination of the contention of atomic operations - Many parallel threads called `atomicAdd` frequently attempting to update the exact same memory location in the input gradient tensor at the same time. - The GPU's memory controler has to serialize these operations, effectively nullifying the benefit of parallel capability at those contention points. - MI300X/MI325X chiplet-based CDNA 3 architeture amplified the issue. - When contending threads reside on different XCDs, resolving the atomic operation requires high-latency coherence traffic across the Infinity Fabric interconnect. - The implementation change eliminates hardware-level serialization and cross-chiplet coherence traffic caused by many `atomicAdd`. - Improved memory access pattern and locality - Write coalescing - The regular sum writes `idata[index] = static_cast(grad_sum);` can be perfectly coalesced by GPUs. - Read locality - Even though there are many (potentially repeated) reads from the output tensor (`static_cast(odata[output_idx])`), these are highly cache-friendly, meaning the data for one thread is likely to be in the L1 or L2 cache already due to an access from a neighboring thread. - Trade-off: computation for memory synchronization - The recalculation of interpolation weights fits well on high-computational-throughput modern GPUs like MI300X/MI325X. - Removal of atomic operations avoids expensive memory synchronization. --- Optimizations of `grid_sampler_2d_backward` will be addressed in a separate PR.

We already provided an easy-to-extend interface in #161062 for implementing load-balancing and in this PR we start with adding a Round-Robin solution as an example and also a verification. This can be easily adapted to other solutions like Shortest-processing-time-first/ Longest-processing-time-first with extra padding added for collectives. - Added a new type of `_LoadBalancer` implementation `_PTRRLoadBalancer` which is designed for `flex_attention()`. This load-balance strategy analyzes the `BlockMask` sparsity info and perform Round-Robin (unlike traditional Round-Robin doing it in circular order, we do in zig-zag order). - Make `_context_parallel_buffers` and `context_parallel_unshard` handle batched load-balance index (previously it can only handle non-batched load-balance index), like in `create_cp_block_mask`. **Test** `pytest test/distributed/tensor/test_attention.py` Pull Request resolved: https://github.com/pytorch/pytorch/pull/163617 Approved by: https://github.com/fegin --- test/distributed/tensor/test_attention.py | 206 +++++++++++------- .../tensor/experimental/_attention.py | 64 +++--- .../tensor/experimental/_load_balancer.py | 199 ++++++++++++++++- 3 files changed, 358 insertions(+), 111 deletions(-) diff --git a/test/distributed/tensor/test_attention.py b/test/distributed/tensor/test_attention.py index 15de2b17bd38..4806c1b71d0d 100644 --- a/test/distributed/tensor/test_attention.py +++ b/test/distributed/tensor/test_attention.py @@ -1,10 +1,9 @@ # Copyright (c) Meta Platforms, Inc. and affiliates # Owner(s): ["oncall: distributed"] -import functools import itertools import random import unittest -from typing import Callable, ClassVar, Optional, Union +from typing import Any, Callable, ClassVar, Optional import torch import torch.distributed as dist @@ -32,6 +31,7 @@ from torch.distributed.tensor.experimental._load_balancer import ( _HeadTailLoadBalancer, _LoadBalancer, _PerDocumentHeadTailLoadBalancer, + _PTRRLoadBalancer, ) from torch.distributed.tensor.parallel import parallelize_module from torch.nn.attention import sdpa_kernel, SDPBackend @@ -39,6 +39,7 @@ from torch.nn.attention.flex_attention import ( _mask_mod_signature, AuxOutput, AuxRequest, + BlockMask, create_block_mask, flex_attention, ) @@ -391,9 +392,7 @@ def generate_random_lengths_in_chunks( return [num_chunks * chunk_size for num_chunks in num_chunks_per_document] -def length_to_offsets( - lengths: list[list[int]], device: Union[str, torch.device] -) -> Tensor: +def length_to_offsets(lengths: list[list[int]], device: str | torch.device) -> Tensor: """Converts a list of lengths to a list of offsets.

HOPs have bodies that have already been traced by Dynamo, and after Animesh's PR, does have the annotations. But when we lower that Dynamo HOP body to aten in either pre-dispatch or post-dispatch, we need to propagate the annotations to the aten nodes. AOTAutograd does this indirectly by piggybacking off the `PropagateUnbackedSymInts` fx.Interpreter. I'm not sure if all HOPs should be using it to trace their joints or not. This PR adds an interpreter to local_map's implementation.

The name of this attribute is up for debate. The advantage of the `_global_rank_permutation` Tensor is that it is _the same_ Tensor for the root mesh and all its children, so it doesn't need to be copied/reallocated.

In other languages the solution to this would be to add a private overload of the constructor. Python doesn't natively allow this, but in this PR I managed to build something that approximates it. This new private constructor basically only takes `_layout`, `_global_rank_permutation`, and `mesh_dim_names`. With such a constructor we can effectively simplify a lot of callsites and get rid of the `_create_mesh_from_ranks` helper method. That's a good thing because it was instantiating many DeviceMeshes in a for loop, which always felt unnecessary.

FSDP2 is not directly related. ~~This PR adds `GradMode::is_enabled()` check to caching condition. Caching is now disabled in `no_grad()` contexts to prevent storing tensors with incorrect gradient state. Ensures correctness at the cost of using cache.~~ This PR proposes separate caches for gradient-enabled and gradient-disabled modes. Adds tests.

When we decompose matmul by reduction dimension we result in partials that needs additional reduction, we allocate memory for accumulator. Decomposition should not produce small (thin) mms that can not efficiently load the GPU. Limiting for minimal size of the shard 1024 (found empirically by testing in torchtitan). scaled_mm is not supported yet for this case.

This modification sets up the infrastructure for adding new templates based on new scaling modes, such as deepseek-style scaling (a follow-up diff), as new scaling modes (deepseek, block, group) scale before the accumulation (as opposed to per-tensor and per-row scaling, which apply scaling after accumulation). This modification also further enables Inductor to infer a scaling type based on the shape of the scaling tensors, which makes existing infrastructure more extensible to new scaling modes.

Added limited support for sub meshes by properly computing rank coordinates for a given sub mesh. The implementation follows similar approach to collectives. We infer all sub meshes for the given dimensions and compute each rank's coordinates with respect to is sub mesh.

The problem is occuring because in sharding_prop we use FakeTensors to compute an operation size (so we don't have to use the full "real" data). We turn off proxy tracing while we're doing that because we don't want the FakeTensor ops to end up in the graph. We then use that size when doing later operations. Normally this is no problem - but when those sizes are dynamic shapes then we have a problem - the proxy tracer wants to track the provenance of all shape operations (`s1*s2`) but since tracing is disabled it doesn't see the operation and when we then use the result shape later on the proxy tracer gets all confused (because the SymNode appeared out of nowhere). At first we were thinking to never disable shape tracing - but that caused a slew of other downstream problems (lots of code that actually needs the shape tracing to be disabled) so instead we enable having a "sym tracing override" and surgically when we disable proxy tracing we leave shape tracing enabled. After this change the dtensor embedding is "fixed" but then runs afoul of a FakeTensor cache bug - which is fixed in the next PR.

If we have "s1" coming in + from both tensor1 and tensor2 and we pick the wrong one we could end up + keeping a tensor alive longer than intended. + + - There's no guarantee that those values are inputs to the graph: If we have + "s1*s2" computed in a graph #1 and used in graph #2 there's no guarantee + that the input that holds "s1" is actually an input on graph #2. + + - The decomposition isn't guaranteed to be the same: Sympy can "simplify" + expressions so it's possible that our inputs are "s1*s2" and "s3" but we + decompose it into "s1" and "s2*s3" - which wouldn't be found. + + Other ways we could handle this: + + - Don't: Just require that all inputs are tracked properly. This is the + "correct" solution but harder because you need to track down each + potential problem one by one and fix them. And when it fails it's a lot of + work to figure out both why it's failing and the right way to fix it. This + is complicated by the fact that a stashed value could be incorrect but + work fine until we happen to get an graph break in the wrong place - so it + may be a while before the bug is found. (Maybe we need a "dynamo abuse + mode" where we run tests with as many graph breaks inserted as possible?) + + - Track SymNode ops separately from proxy tracing: Right now SymNode + operations are tracked as part of the proxy tracing - so when we disable + proxy tracing we also disable SymNode tracing. But we don't have to do + that - we could instead always have SymNodes track where they came from + and just use that when needed. This solves the problem of tracing being + temporarily turned off but doesn't help if an input isn't present after a + graph break. + + - Better decomposition: Right now the decomposition is pretty simple. We do + have a sat-solver available to us so we could theoretically do a better + job figuring out a "correct" decomposition.

For now, when we're proxy tracing just don't bother caching operations that contain SymNodes in the output. The problem is that the proxy tracer relies on SymNode identity and our cache doesn't preserve that. It can be fixed (and I left some notes in _validate_symbolic_output_for_caching() how) but it's not worth it for now. If we aren't proxy tracing then caching is fine. Thus these changes: 1. Our cache key needs to include whether we were actively tracing or not - this way if we create a cache entry when we weren't tracing and then we try to use it when we ARE tracing it gets rerun. 2. If there's a SymNode in the output then bypass tracing. 3. Some general cleanup of the output validation - we were unnecessarily doing it as a two-step process when it could just be a single step (it's still two parts internally but only a single outer try/except).

Global de-scales are naturally device tensors, but using cublas' device-pointer mode for `alpha`/`beta` has an interesting lifetime implication - the `alpha` tensor must be valid & correct until the end of the matmul call, *not* just the launch (as for host values). To enable this, I added device-constant memory for `one` and `zero`, along with a statically-held single-fp32-value tensor, which is valid from the first passed-`alpha` invocation of `scaled_gemm` to the end of the program. User-passed values are copied into this perpetual buffer to ensure lifetime requirements are met.

Fix internal assertion in torch.linalg.solve for singular matrices (#165254) Fixes #163962 by special casing MPS in the negative status code branch in `_linalg_check_errors`. Checks if info is [`MPSMatrixDecompositionStatus.singular`](https://developer.apple.com/documentation/metalperformanceshaders/mpsmatrixdecompositionstatus/singular) (which has a raw value of -2). I didn't find an official Apple source with this raw value (besides printing the enum value), so I'm not sure if we can (or should) depend on it? Is there a way to directly get the Objective-C enum value in C++?

However, this isn't safe, because `wrap_post_compile` will make `self` unserializable, since it needs to load triton kernels and stuff! So instead, on AOTAutogradCache load, we preserve the bytes that were used to load the object to begin with, and return that object on a call to serialize(). This effectively makes it so that we save a copy of the pre-hydrated artifact, without needing to do an eager copy until someone actually calls `serialize`. Test Plan: Run ```py import torch class M(torch.nn.Module): def __init__(self): super().__init__() self.linear1 = torch.nn.Linear(2, 4) self.relu = torch.nn.ReLU() self.linear2 = torch.nn.Linear(4, 8) def forward(self, x): return self.linear2(self.relu(self.linear1(x))) device = "cuda" m = M().to(device) sample_inputs = (torch.randn(2, 2, device=device),) eager_out = m(*sample_inputs) with torch._dynamo.config.patch("enable_aot_compile", True): compiled_fn_path = "./m.pt" compiled_fn = torch.compile( m, fullgraph=True ).forward.aot_compile((sample_inputs, {})) compiled_fn.save_compiled_function(compiled_fn_path) torch._dynamo.reset() with torch.compiler.set_stance("fail_on_recompile"): with open(compiled_fn_path, "rb") as f: loaded_fn = torch.compiler.load_compiled_function(f) assert loaded_fn is not None compiled_out = loaded_fn(m, *sample_inputs) assert torch.allclose(eager_out, compiled_out) ``` twice, see that it succeeds.

The name of this attribute is up for debate. The advantage of the `_global_rank_permutation` Tensor is that it is _the same_ Tensor for the root mesh and all its children, so it doesn't need to be copied/reallocated.

In other languages the solution to this would be to add a private overload of the constructor. Python doesn't natively allow this, but in this PR I managed to build something that approximates it. This new private constructor basically only takes `_layout`, `_global_rank_permutation`, and `mesh_dim_names`. With such a constructor we can effectively simplify a lot of callsites and get rid of the `_create_mesh_from_ranks` helper method. That's a good thing because it was instantiating many DeviceMeshes in a for loop, which always felt unnecessary.

(I think @ezyang spotted this issue, but we have no test to capture this) Meanwhile, I notice another bug that when we normalize a `_StridedShard`'s placement, it will also trigger parent class `Shard`'s `split_tensor` method because it will create a Shard class [here](https://github.com/pytorch/pytorch/blob/0c14f55de674790fd3b2b5808de9f1a523c4feec/torch/distributed/tensor/_api.py#L783). I think we never test `distribute_tensor` for `_StridedShard` before. So I added a test here to compare against ordered shard. Using classmethod because the _split_tensor logic is different between `Shard` and `_StridedShard`. Basically I want to shard on local tensors without initializing the Shard object: ``` local_tensor = _StridedShard._make_shard_tensor(dim, tensor, mesh, mesh_dim, split_factor=split_factor) local_tensor = Shard._make_shard_tensor(dim, tensor, mesh, mesh_dim) ``` Pull Request resolved: https://github.com/pytorch/pytorch/pull/165533 Approved by: https://github.com/XilunWu --- test/distributed/tensor/test_redistribute.py | 17 ++++ torch/distributed/tensor/_api.py | 34 +++++--- torch/distributed/tensor/placement_types.py | 83 ++++++++++---------- 3 files changed, 82 insertions(+), 52 deletions(-) diff --git a/test/distributed/tensor/test_redistribute.py b/test/distributed/tensor/test_redistribute.py index 8b5d031bccfd..1eb0830422f6 100644 --- a/test/distributed/tensor/test_redistribute.py +++ b/test/distributed/tensor/test_redistribute.py @@ -20,6 +20,7 @@ from torch.distributed.tensor._collective_utils import shard_dim_alltoall from torch.distributed.tensor._dtensor_spec import ShardOrderEntry from torch.distributed.tensor._redistribute import redistribute_local_tensor from torch.distributed.tensor.debug import CommDebugMode +from torch.distributed.tensor.placement_types import _StridedShard from torch.testing._internal.common_utils import ( instantiate_parametrized_tests, parametrize, @@ -1145,6 +1146,22 @@ class DistributeWithDeviceOrderTest(DTensorTestBase): sharded_dt, mesh, tgt_placement, shard_order=None ) + @with_comms + def test_shard_order_same_data_as_strided_shard(self): + device_mesh = init_device_mesh(self.device_type, (4, 2)) + x = torch.randn(8, 4, device=self.device_type) + # specify right-to-left order use _StridedShard + strided_placement = [_StridedShard(-2, split_factor=2), Shard(-2)] + x_strided_dt = distribute_tensor(x, device_mesh, strided_placement) + # specify right-to-left order use ordered shard + x_ordered_dt = self.distribute_tensor( + x, + device_mesh, + placements=[Shard(0), Shard(0)], + shard_order=(ShardOrderEntry(tensor_dim=0, mesh_dims=(1, 0)),), + ) + self.assertEqual(x_ordered_dt.to_local(), x_strided_dt.to_local()) + if __name__ == "__main__": run_tests() diff --git a/torch/distributed/tensor/_api.py b/torch/distributed/tensor/_api.py index 03eec9c7d1d4..5fd66b2c5f8e 100644 --- a/torch/distributed/tensor/_api.py +++ b/torch/distributed/tensor/_api.py @@ -25,6 +25,7 @@ from torch.distributed.tensor._utils import ( normalize_to_torch_size, ) from torch.distributed.tensor.placement_types import ( + _StridedShard, Partial, Placement, Replicate, @@ -776,18 +777,29 @@ def distribute_tensor( # distribute the tensor according to the placements. placements = list(placements) for idx, placement in enumerate(placements): - if placement.is_shard(): - placement = cast(Shard, placement) - if placement.dim < 0: - # normalize shard placement dim - placement = Shard(placement.dim + tensor.ndim) - placements[idx] = placement - local_tensor = placement._shard_tensor( - local_tensor, device_mesh, idx, src_data_rank + if isinstance(placement, Shard): + placement_dim = ( + placement.dim + tensor.ndim if placement.dim < 0 else placement.dim ) - elif placement.is_replicate(): - placement = cast(Replicate, placement) - local_tensor = placement._replicate_tensor( + if isinstance(placement, _StridedShard): + local_tensor = _StridedShard._make_shard_tensor( + placement_dim, + local_tensor, + device_mesh, + idx, + src_data_rank, + split_factor=placement.split_factor, + ) + placements[idx] = _StridedShard( + placement_dim, split_factor=placement.split_factor + ) + else: + local_tensor = Shard._make_shard_tensor( + placement_dim, local_tensor, device_mesh, idx, src_data_rank + ) + placements[idx] = Shard(placement_dim) + elif isinstance(placement, Replicate): + local_tensor = Replicate._make_replicate_tensor( local_tensor, device_mesh, idx, src_data_rank ) else: diff --git a/torch/distributed/tensor/placement_types.py b/torch/distributed/tensor/placement_types.py index d6b7efadee6e..5f68ff03ee22 100644 --- a/torch/distributed/tensor/placement_types.py +++ b/torch/distributed/tensor/placement_types.py @@ -69,9 +69,8 @@ class Shard(Placement): else: return True - @staticmethod - def _make_split_tensor( - dim: int, + def _split_tensor( + self, tensor: torch.Tensor, num_chunks: int, *, @@ -87,47 +86,31 @@ class Shard(Placement): few ranks before calling the collectives (i.e. scatter/all_gather, etc.).

Previously we relied on op input arguments to deduce which devices to get rng state from. Which doesn't work for factory functions such torch.randn. Hence this changes switches to uncondionally collecting rng state from all devices. - Fixing per rank specific computations in _MaskedPartial and Shard placements discovered during test enablement.

(#164341) Three fixes: 1. When doing t[u0] +=1 if u0 is unbacked we could allocate a new unbacked symbol during the the indexing of t[u0] (when we fake trace setitem), namely because meta_select does allocate a new unbacked symbol for the storage offset when we do not know if u0>=0 or u0<0. but the output size/stride of setitem(), does not depend on that new symbol. it's self consumed in setitem so we shall ignore it. 2. Also when we trace through generalized_scatter the applications of the views could allocate unbacked symints but those do not effect final output, we also shall ignore them. 3.Before accessing strides in lowering we shall materialize.

Currently even with tuning enable, filtering will only try a single config in many cases. Avoid filtering with autotune mode, and override MAX_BLOCK limit. Also we always include tiny_config when autotuning is enabled.

Previously we relied on op input arguments to deduce which devices to get rng state from. Which doesn't work for factory functions such torch.randn. Hence this changes switches to uncondionally collecting rng state from all devices. - Fixing per rank specific computations in _MaskedPartial and Shard placements discovered during test enablement.

C++14 support and more! (#165840) Update Eigen pin to 5.0.0 . Tons of new features and perf improvements. Most importantly updates minimum from C++03 to C++14 giving a ton of performance optimizations like properly implemented move operators, simplified code, etc. Also improved vectorization particularily on ARM. We really only use this library as a fallback for sparse operators, but still useful to update it.
