Inductor logging + analysis of torch.profile (#149697)
Prereqs: - https://github.com/pytorch/pytorch/pull/152708 Features: 1. Adds inductor's estimate of flops and bandwidth to the json trace events that perfetto uses. 1. Only use the tflops estimation from triton if we don't have the info from the datasheet because Triton's estimates are inaccurate. I have a backlog item to fix triton flops estimation upstream. New `DeviceInfo` class, and new function `get_device_tflops`. 1. New helpers `countable_fx` and `count_flops_fx` helps get the flops of an `fx.Node`. 1. Extends Triton `torch.profiler` logging to `DebugAutotuner`. 1. New script `profile_analysis.py`: `--augment_trace` adds perf estimates to any perfetto json trace, `--analyze` creates a summary table of these perf estimates, and `--diff` will compare two traces side by side: ```python Device(NVIDIA H100, 0): Kernel Name | resnet Kernel Count | resnet FLOPS | resnet bw gbps | resnet Dur (ms) | resnet Achieved FLOPS % | resnet Achieved Bandwidth % | newresnet

[Inductor] Allow exhaustive autotuning across all GEMM options (#156610)
Differential Revision: D76843916 Exhaustive autotuning is meant to autotune GEMM configs across the entire search space of possible configs. Some of these configs can cause extremely long compilation times and OOMs, especially with configs of the following nature: Excessive register spillage Using much larger amounts of shared memory than available on the hardware This diff prunes out those configs to make exhaustive autotuning more viable, along with supporting exhaustive autotuning for persistent+tma template and decompose_k. Previously, exhaustive autotuning would hang, now we are able to tune shapes in ~5 minutes. Below is a sample log for autotuning with exhaustive: ``` AUTOTUNE mm(1152x21504, 21504x1024) strides: [21504, 1], [1, 21504] dtypes: torch.bfloat16, torch.bfloat16 mm 0.1167 ms 100.0% triton_mm_6270 0.1172 ms 99.6% ACC_TYPE='tl.float32', ALLOW_TF32=False, BLOCK_K=64, BLOCK_M=64, BLOCK_N=256, EVEN_K=True, GROUP_M=8, USE_FAST_ACCUM=False, num_stages=5, num_warps=4, num_consumer_groups=0, num_buffers_warp_spec=0 triton_mm_6522 0.1183 ms 98.6% ACC_TYPE='tl.float32', ALLOW_TF32=False, BLOCK_K=64, BLOCK_M=128, BLOCK_N=128, EVEN_K=True, GROUP_M=8, USE_FAST_ACCUM=False, num_stages=5, num_warps=4, num_consumer_groups=0, num_buffers_warp_spec=0 triton_mm_persistent_tma_7482 0.1190 ms 98.1% ACC_TYPE='tl.float32', ALLOW_TF32=False, A_ROW_MAJOR=True, BLOCK_K=64, BLOCK_M=128, BLOCK_N=128, B_ROW_MAJOR=False, EVEN_K=True, GROUP_M=8, NUM_SMS=132, TMA_SIZE=128, USE_FAST_ACCUM=False, num_stages=5, num_warps=4, num_consumer_groups=0, num_buffers_warp_spec=0 triton_mm_persistent_tma_7483 0.1195 ms 97.6% ACC_TYPE='tl.float32', ALLOW_TF32=False, A_ROW_MAJOR=True, BLOCK_K=64, BLOCK_M=128, BLOCK_N=128, B_ROW_MAJOR=False, EVEN_K=True, GROUP_M=8, NUM_SMS=132, TMA_SIZE=128, USE_FAST_ACCUM=False, num_stages=5, num_warps=8, num_consumer_groups=0, num_buffers_warp_spec=0 triton_mm_6523 0.1274 ms 91.6% ACC_TYPE='tl.float32', ALLOW_TF32=False, BLOCK_K=64, BLOCK_M=128, BLOCK_N=128, EVEN_K=True, GROUP_M=8, USE_FAST_ACCUM=False, num_stages=5, num_warps=8, num_consumer_groups=0, num_buffers_warp_spec=0 triton_mm_6267 0.1285 ms 90.8% ACC_TYPE='tl.float32', ALLOW_TF32=False, BLOCK_K=64, BLOCK_M=64, BLOCK_N=256, EVEN_K=True, GROUP_M=8, USE_FAST_ACCUM=False, num_stages=4, num_warps=4, num_consumer_groups=0, num_buffers_warp_spec=0 triton_mm_6519 0.1287 ms 90.7% ACC_TYPE='tl.float32', ALLOW_TF32=False, BLOCK_K=64, BLOCK_M=128, BLOCK_N=128, EVEN_K=True, GROUP_M=8, USE_FAST_ACCUM=False, num_stages=4, num_warps=4, num_consumer_groups=0, num_buffers_warp_spec=0 triton_mm_persistent_tma_7480 0.1298 ms 89.9% ACC_TYPE='tl.float32', ALLOW_TF32=False, A_ROW_MAJOR=True, BLOCK_K=64, BLOCK_M=128, BLOCK_N=128, B_ROW_MAJOR=False, EVEN_K=True, GROUP_M=8, NUM_SMS=132, TMA_SIZE=128, USE_FAST_ACCUM=False, num_stages=4, num_warps=4, num_consumer_groups=0, num_buffers_warp_spec=0 triton_mm_persistent_tma_7312 0.1302 ms 89.7% ACC_TYPE='tl.float32', ALLOW_TF32=False, A_ROW_MAJOR=True, BLOCK_K=64, BLOCK_M=64, BLOCK_N=256, B_ROW_MAJOR=False, EVEN_K=True, GROUP_M=8, NUM_SMS=132, TMA_SIZE=128, USE_FAST_ACCUM=False, num_stages=4, num_warps=4, num_consumer_groups=0, num_buffers_warp_spec=0 SingleProcess AUTOTUNE benchmarking takes 298.7185 seconds and 21.2569 seconds precompiling for 2210 choices INFO:tritonbench.utils.triton_op:Took 333894.46ms to get benchmark function for pt2_matmul_maxautotune ``` Pull Request resolved: https://github.com/pytorch/pytorch/pull/156610 Approved by: https://github.com/jansel |

[inductor] Add configuration control for CUTLASS operation selection. (#155770)
Added a new configuration option `cutlass_enabled_ops` that allows users to control which operations use CUTLASS lowerings. By default, CUTLASS is enabled for all operations (maintaining backward compatibility), but users can now selectively enable it only for specific operations to optimize compilation time. **Fixes #155718** ## Usage Examples ```bash # Enable CUTLASS for all operations (default behavior) export TORCHINDUCTOR_CUTLASS_ENABLED_OPS="ALL" # Enable CUTLASS only for matrix multiplication operations export TORCHINDUCTOR_CUTLASS_ENABLED_OPS="mm,addmm" # Enable CUTLASS only for batch operations export TORCHINDUCTOR_CUTLASS_ENABLED_OPS="bmm,baddbmm" # Disable CUTLASS for all operations export TORCHINDUCTOR_CUTLASS_ENABLED_OPS="" ``` Pull Request resolved: https://github.com/pytorch/pytorch/pull/155770 Approved by: https://github.com/henrylhtsang |

[inductor][triton pin] add support for new TMA API for mm.py templates (#155723)
Triton 3.4 will remove the experimental TMA APIs: https://github.com/triton-lang/triton/pull/6488 For mm.py templates, this PR adds support for using the new APIs when they are available (and otherwise falls back to the experimental APIs). For flex_attention, we'll remove TMA support for Triton 3.2 and 3.3 (versions of triton that don't have the new API). For mm_scaled_grouped.py, https://github.com/pytorch/pytorch/pull/150944 will remove TMA support for Triton 3.2. Note: we attempted this earlier with https://github.com/pytorch/pytorch/pull/154858, but this broke TMA usage in Triton 3.2.

Inductor logging + analysis of torch.profile (#149697)
Prereqs: - https://github.com/pytorch/pytorch/pull/152708 Features: 1. Adds inductor's estimate of flops and bandwidth to the json trace events that perfetto uses. 1. Only use the tflops estimation from triton if we don't have the info from the datasheet because Triton's estimates are inaccurate. I have a backlog item to fix triton flops estimation upstream. New `DeviceInfo` class, and new function `get_device_tflops`. 1. New helpers `countable_fx` and `count_flops_fx` helps get the flops of an `fx.Node`. 1. Extends Triton `torch.profiler` logging to `DebugAutotuner`. 1. New script `profile_analysis.py`: `--augment_trace` adds perf estimates to any perfetto json trace, `--analyze` creates a summary table of these perf estimates, and `--diff` will compare two traces side by side: ```python Device(NVIDIA H100, 0): Kernel Name | resnet Kernel Count | resnet FLOPS | resnet bw gbps | resnet Dur (ms) | resnet Achieved FLOPS % | resnet Achieved Bandwidth % | newresnet

[inductor] use int64 for large index (#154575)
Split reduction may need add an extra mask to avoid invalid index. Previously we always uses torch.int32 dtype. That causes problem when the tensor numel exceeds 2^31.

Inductor logging + analysis of torch.profile (#149697)
Prereqs: - https://github.com/pytorch/pytorch/pull/152708 Features: 1. Adds inductor's estimate of flops and bandwidth to the json trace events that perfetto uses. 1. Only use the tflops estimation from triton if we don't have the info from the datasheet because Triton's estimates are inaccurate. I have a backlog item to fix triton flops estimation upstream. New `DeviceInfo` class, and new function `get_device_tflops`. 1. New helpers `countable_fx` and `count_flops_fx` helps get the flops of an `fx.Node`. 1. Extends Triton `torch.profiler` logging to `DebugAutotuner`. 1. New script `profile_analysis.py`: `--augment_trace` adds perf estimates to any perfetto json trace, `--analyze` creates a summary table of these perf estimates, and `--diff` will compare two traces side by side: ```python Device(NVIDIA H100, 0): Kernel Name | resnet Kernel Count | resnet FLOPS | resnet bw gbps | resnet Dur (ms) | resnet Achieved FLOPS % | resnet Achieved Bandwidth % | newresnet

Reflect back mutation if we clone misaligned tensors (#154442)
Fix for https://github.com/pytorch/pytorch/issues/152425 inductor specializes whether or not a tensor is 16-bit aligned on the first invocation. then, on subsequent invocations, if we inferred alignment but are passed a non-aligned tensor we clone the tensor. If we infer alignment, then run with unaligned, and mutate the input, we need to reflect back the mutation to the input. This pr adds back that mutation. We could have also been less aggressive about inferring alignment for mutated tensors, but that has a pretty perf hit.See the following benchmark: ``` import torch t = torch.rand(4096 * 4096, device="cuda", dtype=torch.float16) @torch.compile(dynamic=False) def foo(x): return x.add_(1) import triton print(triton.testing.do_bench(lambda: foo(t[:-1]))) torch._dynamo.reset() print(triton.testing.do_bench(lambda: foo(t[1:]))) ``` gives ``` 0.04063070610165596 0.07613472988113162 ``` So almost twice as slow for non-aligned tensors. Tensors changing alignment is a relatively rare case. In the future, we could considering a multi-kernel approach, or codegening a triton kernel that does most of the loads with aligned instructions, and a prologue/epilogue of un-alignment. But, it's yet to be seen this is a huge issue. Pull Request resolved: https://github.com/pytorch/pytorch/pull/154442 Approved by: https://github.com/bobrenjc93, https://github.com/bdhirsh |

[Inductor] FX backend via Wrapper IR (#146942)
# Sub-PRs These PRs contain refactors from the main one. They should be reviewed and merged first. - https://github.com/pytorch/pytorch/pull/150458 - https://github.com/pytorch/pytorch/pull/152391 - https://github.com/pytorch/pytorch/pull/152587 # Feature The goals of this PR are twofold. ## Goal 1: Introduce Wrapper IR as an intermediate step in wrapper codegen. In addition to Triton/C++/Halide kernels, Inductor also generates "wrapper" code which allocates memory and calls the kernels. Originally, this wrapper code was fairly standard Python which resembled a user-written PyTorch program. Over time, various wrapper code generators have been added to accommodate things like AOTInductor, which prefers C++ code for static compilation. This complexity has bled into other parts of the codebase, as we now need if/else statements to choose between Python and C++ macros. (See an example [here](https://github.com/pytorch/pytorch/blob/main/torch/_inductor/ir.py#L5515-L5522).) Since most of these code generation steps are conceptually identical across target languages, it seems reasonable to refactor them into some kind of intermediate representation which can be shared between the various backends. This might also make it easier to develop out-of-tree backends which cannot put their own macros in core Inductor components. This PR takes some initial steps to formalize Inductor's wrapper codegen by generalizing the existing Memory Planning IR into a fully fledged Wrapper IR. This is pretty much identical to the existing Memory Planning IR, but it supports a richer set of ops for things like kernel definitions and calls. This refactor could help encapsulate wrapper codegen. Ideally, we don't need to worry about direct Python/C++ codegen in the main compiler files such as `ir.py`, and can instead defer these to classes like `PythonWrapperCodegen` and `CppWrapperCpu`, which operate on the Wrapper IR. ## Goal 2: Convert Wrapper IR into FX IR. One of the main benefits of Wrapper IR is to enable more diverse Inductor backends. This PR introduces a converter from Wrapper IR into [FX IR](https://pytorch.org/docs/stable/fx.html), which is the intermediate representation most commonly used in PyTorch graph compilers. The purpose of this is to enable out-of-tree backends to consume Inductor's output in FX IR, which would hopefully make Inductor easier to leverage in novel compilers, hardware accelerators, etc. It's not trivial to generate Python or C++ code which Inductor can compile and run, and doing so may require changes to other core Inductor files, for the reasons outlined in the previous section. The goal of supporting FX output is to enable something like `torch.compile`'s [custom backend](https://pytorch.org/docs/stable/torch.compiler_custom_backends.html) system, in which an out-of-tree backend can receive an optimized FX graph from Inductor, and compile and run it however it likes. The typical users of this feature would likely not be part of PyTorch, and may or may not support running a kernel in eager mode. However, they can understand what `torch.empty_strided` means, compile and run Triton kernels, etc. So we just need to present them with an FX graph saying what code Inductor wants to run, which should be easier to analyze and transform in a third party system than Python or C++ source. Since FX IR is fairly stable, this mechanism should hopefully isolate third-party backends, hardware accelerators, etc. from the implementation details of Inductor, and vice versa. # Current status Things that seem to work: - Converted a lot of the most common Python codegen lines to Wrapper IR lines. - Handled the following cases, in addition to what was already in the Memory Planning IR: - Comments - Triton kernels - Extern/fallback kernels - Freeing tensors (`del buf0`) - MultiOutput - Graph outputs - ReinterpretView / StorageBox, for both call args and outputs. - FX conversion asserts that the program only contains Wrapper IR lines, and not strings of Python/C++ code. - Prototype FX converter which can handle some of the most common use cases. - Defining Triton kernels, and putting them in a side table using TorchDynamo's existing [utilities](https://dev-discuss.pytorch.org/t/higher-order-operators-2023-10/1565). - Calling wrapped Triton kernels. - Calling extern kernels and certain types of fallback kernels. - Support both `extern_kernels.*` and `aten.*`. - Support multi-output kernels like `torch.topk`. - Graphs with multiple inputs/outputs. - Training i.e. calling `Tensor.backward()` in a compiled function. - Graph breaks (training). - Run the `torch.fx.GraphModule` on GPU using the standard `__call__` method. This makes it easy to test the correctness of FX codegen. Things that don't work: - Both Wrapper IR and Wrapper -> FX coverage are currently best effort. There are still features which aren't captured as Wrapper IR lines, and fall back to plain strings. This representation is functionally correct but probably not rich enough to achieve the goals outlined in the previous sections. - Fallback kernels seem like the most difficult thing to fully cover, since they each define their own Python/C++ macros that would need to be converted to FX. - Size/alignment asserts are currently disabled via the config file. It's possible to generate FX IR for these, but it seems reasonable to defer these sanity checks to a later PR. - CommBuffer's and distributed communication are not yet supported. An earlier version of this PR attempted to implement this by calling `empty_strided_p2p`. However, building and testing distributed support seems non-trivial, so it's probably better to defer this. # Out-of-tree compilers With this PR, out of tree backends will be able to do further compilation on the FX graphs by subclassing `WrapperFxCodegen` and overriding the `compile_graph` function. This follows the same API as torch.compile's [custom backends](https://pytorch.org/docs/stable/torch.compiler_custom_backends.html), where the user simply returns a callable running the graph. The callable need not be a method of `GraphModule` or any other PyTorch class. See an example below. ``` from torch._inductor.codegen.wrapper_fxir import WrapperFxCodegen class MyCustomBackend(WrapperFxCodegen): def compile_graph(self, gm): # Add 1 to the graph's outputs def compiled_fn(*args): return [x + 1 for x in gm.graph.forward(*args)] return compiled_fn ``` # Example FX graphs This section contains some example FX graphs generated by Inductor. The correctness of these graphs was verified against eager mode by calling the corresponding `GraphModule`. Here's an FX graph calling a basic Triton kernel. Notice how outputs are allocated with `torch.empty_strided`, and the Triton kernel is called by reference to Dynamo's triton side table. ``` graph(): %arg0_1 : [num_users=1] = placeholder[target=arg0_1] %arg1_1 : [num_users=1] = placeholder[target=arg1_1] %buf0 : [num_users=2] = call_function[target=torch.empty_strided](args = ((8,), (1,)), kwargs = {dtype: torch.float32, device: cuda:0}) %triton_kernel_wrapper_mutation : [num_users=0] = call_function[target=torch.ops.higher_order.triton_kernel_wrapper_mutation](args = (), kwargs = {kernel_idx: 0, constant_args_idx: 0, grid: [(8,)], tma_descriptor_metadata: {}, kwargs: {in_ptr0: %arg1_1, in_ptr1: %arg0_1, out_ptr0: %buf0, xnumel: 8, XBLOCK: 8}}) return (buf0,) ``` Here's a more complicated graph that calls a `torch.addmm` extern kernel. ``` graph(): %arg0_1 : [num_users=1] = placeholder[target=arg0_1] %arg1_1 : [num_users=2] = placeholder[target=arg1_1] %buf0 : [num_users=3] = call_function[target=torch.empty_strided](args = ((), ()), kwargs = {dtype: torch.float32, device: cuda:0}) %triton_kernel_wrapper_mutation : [num_users=0] = call_function[target=torch.ops.higher_order.triton_kernel_wrapper_mutation](args = (), kwargs = {kernel_idx: 0, constant_args_idx: 0, grid: [(1,)], tma_descriptor_metadata: {}, kwargs: {in_ptr0: %arg1_1, out_ptr0: %buf0, xnumel: 1, r0_numel: 129, XBLOCK: 1}}) %buf2 : [num_users=2] = call_function[target=torch.empty_strided](args = ((129, 1), (1, 1)), kwargs = {dtype: torch.float32, device: cuda:0}) %addmm : [num_users=0] = call_function[target=torch.addmm](args = (%buf0, %arg0_1, %arg1_1), kwargs = {alpha: 1, beta: 1, out: %buf2}) %delete : [num_users=0] = call_function[target=torch._inductor.codegen.wrapper_fxir.delete](args = (%buf0,), kwargs = {}) return (buf2,) ``` Here's a graph which indexes into a tuple using `operator.getitem`. This is necessary to use the output of the `torch.topk` operation. ``` graph(): %arg0_1 : [num_users=1] = placeholder[target=arg0_1] %buf0 : [num_users=3] = call_function[target=torch.ops.aten.topk.default](args = (%arg0_1, 2), kwargs = {}) %buf1 : [num_users=2] = call_function[target=operator.getitem](args = (%buf0, 0), kwargs = {}) %buf2 : [num_users=2] = call_function[target=operator.getitem](args = (%buf0, 1), kwargs = {}) %delete : [num_users=0] = call_function[target=torch._inductor.codegen.wrapper_fxir.delete](args = (%buf0,), kwargs = {}) %triton_kernel_wrapper_mutation : [num_users=0] = call_function[target=torch.ops.higher_order.triton_kernel_wrapper_mutation](args = (), kwargs = {kernel_idx: 0, constant_args_idx: 0, grid: [(2,)], tma_descriptor_metadata: {}, kwargs: {in_out_ptr0: %buf1, xnumel: 2, XBLOCK: 2}}) %triton_kernel_wrapper_mutation_1 : [num_users=0] = call_function[target=torch.ops.higher_order.triton_kernel_wrapper_mutation](args = (), kwargs = {kernel_idx: 1, constant_args_idx: 1, grid: [(2,)], tma_descriptor_metadata: {}, kwargs: {in_out_ptr0: %buf2, xnumel: 2, XBLOCK: 2}}) return (buf1, buf2) ``` Here's a graph that reinterprets an output tensor using `torch.as_strided`. This is one way to handle Inductor's `ReinterpretView` op. ``` graph(): %arg0_1 : [num_users=1] = placeholder[target=arg0_1] %arg1_1 : [num_users=1] = placeholder[target=arg1_1] %buf0 : [num_users=2] = call_function[target=torch.empty_strided](args = ((2, 4), (4, 1)), kwargs = {dtype: torch.float32, device: cuda:0}) %triton_kernel_wrapper_mutation : [num_users=0] = call_function[target=torch.ops.higher_order.triton_kernel_wrapper_mutation](args = (), kwargs = {kernel_idx: 0, constant_args_idx: 0, grid: [(8,)], tma_descriptor_metadata: {}, kwargs: {in_ptr0: %arg0_1, in_ptr1: %arg1_1, out_ptr0: %buf0, xnumel: 8, XBLOCK: 8}}) %buf0_view_buf0_0 : [num_users=1] = call_function[target=torch.as_strided](args = (%buf0, (8,), (1,), 0), kwargs = {}) return (buf0_view_buf0_0,) ``` Here's a graph with dynamic shapes. This one is a little bit funky. Inductor provides a graph input for each shape symbol, which we map to a placeholder, in this example `s6`. Then, shape expressions in the generated code can refer to the symbol `s6`. The size hint for `s6` is stored in `node.meta["val"]` where `node` is the placeholder defining it. This works out in the generated python code because the placeholder defines a Python variable with the name `s6`. ``` graph(): %s6 : [num_users=0] = placeholder[target=s6] %arg1_1 : [num_users=1] = placeholder[target=arg1_1] %arg2_1 : [num_users=1] = placeholder[target=arg2_1] %buf0 : [num_users=2] = call_function[target=torch.empty_strided](args = ((s6,), (1,)), kwargs = {dtype: torch.float32, device: cuda:0}) %triton_kernel_wrapper_mutation : [num_users=0] = call_function[target=torch.ops.higher_order.triton_kernel_wrapper_mutation](args = (), kwargs = {kernel_idx: 0, constant_args_idx: 0, grid: [[-(((-s6)//8)), 1, 1]], tma_descriptor_metadata: {}, kwargs: {in_ptr0: %arg2_1, in_ptr1: %arg1_1, out_ptr0: %buf0, xnumel: s6, XBLOCK: 8}}) return buf0 ``` Here's another graph, this time with dynamic shapes and strides. The grid expression is more complex since the numel is a product of dimensions. ``` graph(): %s10 : [num_users=0] = placeholder[target=s10] %arg1_1 : [num_users=1] = placeholder[target=arg1_1] %arg2_1 : [num_users=1] = placeholder[target=arg2_1] %buf0 : [num_users=2] = call_function[target=torch.empty_strided](args = ([s10, s10], [s10, 1]), kwargs = {dtype: torch.float32, device: cuda:0}) %triton_kernel_wrapper_mutation : [num_users=0] = call_function[target=torch.ops.higher_order.triton_kernel_wrapper_mutation](args = (), kwargs = {kernel_idx: 0, constant_args_idx: 0, grid: [[-(((s10**2)//(-64))), 1, 1]], tma_descriptor_metadata: {}, kwargs: {in_ptr0: %arg2_1, in_ptr1: %arg1_1, out_ptr0: %buf0, xnumel: s10**2, XBLOCK: 64}}) return buf0 ``` Pull Request resolved: https://github.com/pytorch/pytorch/pull/146942 Approved by: https://github.com/jansel |

The goal of supporting FX output is to enable something like `torch.compile`'s [custom backend](https://pytorch.org/docs/stable/torch.compiler_custom_backends.html) system, in which an out-of-tree backend can receive an optimized FX graph from Inductor, and compile and run it however it likes. The typical users of this feature would likely not be part of PyTorch, and may or may not support running a kernel in eager mode. However, they can understand what `torch.empty_strided` means, compile and run Triton kernels, etc. So we just need to present them with an FX graph saying what code Inductor wants to run, which should be easier to analyze and transform in a third party system than Python or C++ source. Since FX IR is fairly stable, this mechanism should hopefully isolate third-party backends, hardware accelerators, etc. from the implementation details of Inductor, and vice versa. # Current status Things that seem to work: - Converted a lot of the most common Python codegen lines to Wrapper IR lines. - Handled the following cases, in addition to what was already in the Memory Planning IR: - Comments - Triton kernels - Extern/fallback kernels - Freeing tensors (`del buf0`) - MultiOutput - Graph outputs - ReinterpretView / StorageBox, for both call args and outputs. - FX conversion asserts that the program only contains Wrapper IR lines, and not strings of Python/C++ code. - Prototype FX converter which can handle some of the most common use cases. - Defining Triton kernels, and putting them in a side table using TorchDynamo's existing [utilities](https://dev-discuss.pytorch.org/t/higher-order-operators-2023-10/1565). - Calling wrapped Triton kernels. - Calling extern kernels and certain types of fallback kernels. - Support both `extern_kernels.*` and `aten.*`. - Support multi-output kernels like `torch.topk`. - Graphs with multiple inputs/outputs. - Training i.e. calling `Tensor.backward()` in a compiled function. - Graph breaks (training). - Run the `torch.fx.GraphModule` on GPU using the standard `__call__` method. This makes it easy to test the correctness of FX codegen. Things that don't work: - Both Wrapper IR and Wrapper -> FX coverage are currently best effort. There are still features which aren't captured as Wrapper IR lines, and fall back to plain strings. This representation is functionally correct but probably not rich enough to achieve the goals outlined in the previous sections. - Fallback kernels seem like the most difficult thing to fully cover, since they each define their own Python/C++ macros that would need to be converted to FX. - Size/alignment asserts are currently disabled via the config file. It's possible to generate FX IR for these, but it seems reasonable to defer these sanity checks to a later PR. - CommBuffer's and distributed communication are not yet supported. An earlier version of this PR attempted to implement this by calling `empty_strided_p2p`. However, building and testing distributed support seems non-trivial, so it's probably better to defer this. # Out-of-tree compilers With this PR, out of tree backends will be able to do further compilation on the FX graphs by subclassing `WrapperFxCodegen` and overriding the `compile_graph` function. This follows the same API as torch.compile's [custom backends](https://pytorch.org/docs/stable/torch.compiler_custom_backends.html), where the user simply returns a callable running the graph. The callable need not be a method of `GraphModule` or any other PyTorch class. See an example below. ``` from torch._inductor.codegen.wrapper_fxir import WrapperFxCodegen class MyCustomBackend(WrapperFxCodegen): def compile_graph(self, gm): # Add 1 to the graph's outputs def compiled_fn(*args): return [x + 1 for x in gm.graph.forward(*args)] return compiled_fn ``` # Example FX graphs This section contains some example FX graphs generated by Inductor. The correctness of these graphs was verified against eager mode by calling the corresponding `GraphModule`. Here's an FX graph calling a basic Triton kernel. Notice how outputs are allocated with `torch.empty_strided`, and the Triton kernel is called by reference to Dynamo's triton side table. ``` graph(): %arg0_1 : [num_users=1] = placeholder[target=arg0_1] %arg1_1 : [num_users=1] = placeholder[target=arg1_1] %buf0 : [num_users=2] = call_function[target=torch.empty_strided](args = ((8,), (1,)), kwargs = {dtype: torch.float32, device: cuda:0}) %triton_kernel_wrapper_mutation : [num_users=0] = call_function[target=torch.ops.higher_order.triton_kernel_wrapper_mutation](args = (), kwargs = {kernel_idx: 0, constant_args_idx: 0, grid: [(8,)], tma_descriptor_metadata: {}, kwargs: {in_ptr0: %arg1_1, in_ptr1: %arg0_1, out_ptr0: %buf0, xnumel: 8, XBLOCK: 8}}) return (buf0,) ``` Here's a more complicated graph that calls a `torch.addmm` extern kernel. ``` graph(): %arg0_1 : [num_users=1] = placeholder[target=arg0_1] %arg1_1 : [num_users=2] = placeholder[target=arg1_1] %buf0 : [num_users=3] = call_function[target=torch.empty_strided](args = ((), ()), kwargs = {dtype: torch.float32, device: cuda:0}) %triton_kernel_wrapper_mutation : [num_users=0] = call_function[target=torch.ops.higher_order.triton_kernel_wrapper_mutation](args = (), kwargs = {kernel_idx: 0, constant_args_idx: 0, grid: [(1,)], tma_descriptor_metadata: {}, kwargs: {in_ptr0: %arg1_1, out_ptr0: %buf0, xnumel: 1, r0_numel: 129, XBLOCK: 1}}) %buf2 : [num_users=2] = call_function[target=torch.empty_strided](args = ((129, 1), (1, 1)), kwargs = {dtype: torch.float32, device: cuda:0}) %addmm : [num_users=0] = call_function[target=torch.addmm](args = (%buf0, %arg0_1, %arg1_1), kwargs = {alpha: 1, beta: 1, out: %buf2}) %delete : [num_users=0] = call_function[target=torch._inductor.codegen.wrapper_fxir.delete](args = (%buf0,), kwargs = {}) return (buf2,) ``` Here's a graph which indexes into a tuple using `operator.getitem`. This is necessary to use the output of the `torch.topk` operation. ``` graph(): %arg0_1 : [num_users=1] = placeholder[target=arg0_1] %buf0 : [num_users=3] = call_function[target=torch.ops.aten.topk.default](args = (%arg0_1, 2), kwargs = {}) %buf1 : [num_users=2] = call_function[target=operator.getitem](args = (%buf0, 0), kwargs = {}) %buf2 : [num_users=2] = call_function[target=operator.getitem](args = (%buf0, 1), kwargs = {}) %delete : [num_users=0] = call_function[target=torch._inductor.codegen.wrapper_fxir.delete](args = (%buf0,), kwargs = {}) %triton_kernel_wrapper_mutation : [num_users=0] = call_function[target=torch.ops.higher_order.triton_kernel_wrapper_mutation](args = (), kwargs = {kernel_idx: 0, constant_args_idx: 0, grid: [(2,)], tma_descriptor_metadata: {}, kwargs: {in_out_ptr0: %buf1, xnumel: 2, XBLOCK: 2}}) %triton_kernel_wrapper_mutation_1 : [num_users=0] = call_function[target=torch.ops.higher_order.triton_kernel_wrapper_mutation](args = (), kwargs = {kernel_idx: 1, constant_args_idx: 1, grid: [(2,)], tma_descriptor_metadata: {}, kwargs: {in_out_ptr0: %buf2, xnumel: 2, XBLOCK: 2}}) return (buf1, buf2) ``` Here's a graph that reinterprets an output tensor using `torch.as_strided`. This is one way to handle Inductor's `ReinterpretView` op. ``` graph(): %arg0_1 : [num_users=1] = placeholder[target=arg0_1] %arg1_1 : [num_users=1] = placeholder[target=arg1_1] %buf0 : [num_users=2] = call_function[target=torch.empty_strided](args = ((2, 4), (4, 1)), kwargs = {dtype: torch.float32, device: cuda:0}) %triton_kernel_wrapper_mutation : [num_users=0] = call_function[target=torch.ops.higher_order.triton_kernel_wrapper_mutation](args = (), kwargs = {kernel_idx: 0, constant_args_idx: 0, grid: [(8,)], tma_descriptor_metadata: {}, kwargs: {in_ptr0: %arg0_1, in_ptr1: %arg1_1, out_ptr0: %buf0, xnumel: 8, XBLOCK: 8}}) %buf0_view_buf0_0 : [num_users=1] = call_function[target=torch.as_strided](args = (%buf0, (8,), (1,), 0), kwargs = {}) return (buf0_view_buf0_0,) ``` Here's a graph with dynamic shapes. This one is a little bit funky. Inductor provides a graph input for each shape symbol, which we map to a placeholder, in this example `s6`. Then, shape expressions in the generated code can refer to the symbol `s6`. The size hint for `s6` is stored in `node.meta["val"]` where `node` is the placeholder defining it. This works out in the generated python code because the placeholder defines a Python variable with the name `s6`. ``` graph(): %s6 : [num_users=0] = placeholder[target=s6] %arg1_1 : [num_users=1] = placeholder[target=arg1_1] %arg2_1 : [num_users=1] = placeholder[target=arg2_1] %buf0 : [num_users=2] = call_function[target=torch.empty_strided](args = ((s6,), (1,)), kwargs = {dtype: torch.float32, device: cuda:0}) %triton_kernel_wrapper_mutation : [num_users=0] = call_function[target=torch.ops.higher_order.triton_kernel_wrapper_mutation](args = (), kwargs = {kernel_idx: 0, constant_args_idx: 0, grid: [[-(((-s6)//8)), 1, 1]], tma_descriptor_metadata: {}, kwargs: {in_ptr0: %arg2_1, in_ptr1: %arg1_1, out_ptr0: %buf0, xnumel: s6, XBLOCK: 8}}) return buf0 ``` Here's another graph, this time with dynamic shapes and strides. The grid expression is more complex since the numel is a product of dimensions. ``` graph(): %s10 : [num_users=0] = placeholder[target=s10] %arg1_1 : [num_users=1] = placeholder[target=arg1_1] %arg2_1 : [num_users=1] = placeholder[target=arg2_1] %buf0 : [num_users=2] = call_function[target=torch.empty_strided](args = ([s10, s10], [s10, 1]), kwargs = {dtype: torch.float32, device: cuda:0}) %triton_kernel_wrapper_mutation : [num_users=0] = call_function[target=torch.ops.higher_order.triton_kernel_wrapper_mutation](args = (), kwargs = {kernel_idx: 0, constant_args_idx: 0, grid: [[-(((s10**2)//(-64))), 1, 1]], tma_descriptor_metadata: {}, kwargs: {in_ptr0: %arg2_1, in_ptr1: %arg1_1, out_ptr0: %buf0, xnumel: s10**2, XBLOCK: 64}}) return buf0 ``` Pull Request resolved: https://github.com/pytorch/pytorch/pull/146942 Approved by: https://github.com/jansel |

[Inductor] Add decomposeK as an autotuning choice for mm (#150654)
As a result of adding subgraph as a choice to inductor https://github.com/pytorch/pytorch/pull/149761 and enabling FP32 output from PyTorch GEMMs from FP16/BF16 inputs: https://github.com/pytorch/pytorch/pull/150812, this PR enables decompose_k as an autotuning choice for Inductor in generating the fastest matmuls with Triton. DecomposeK is currently only enabled for `torch.compile`. Followups: * decompose_k does not currently support epilogue fusion, which will take some work to enable * Enable autotuning the bmm with Triton Templates as well without requiring tons of more compile time, async compilation. Anecdotal evidence shows that Triton BMM performs better usually than aten BMM * Add for addmm * Enable for Inference and AOTI Below are the results of running TritonBench for Split-K shapes, comparing the aten performance versus pt2_triton, which now autotunes on decompose_k, seeing >10% speedup compared to aten on average, and for some shapes over 3x the performance of the best Triton mm previously: <img width="929" alt="Screenshot 2025-04-28 at 9 15 39 PM" src="https://github.com/user-attachments/assets/27d85bbc-4f3a-43a6-a8fa-d4a5bbb8c999" /> TorchInductor Benchmark Dashboard: <img width="1727" alt="Screenshot 2025-04-30 at 2 02 53 PM" src="https://github.com/user-attachments/assets/4acd7ffc-407f-4cfd-98bb-2e3d8b1f00b3" /> We see speedups across all runs for training.

Add precedence to the infix printing done by sympy_str. (#151920)
Add precedence to the infix printing done by sympy_str. Without this change sympy_str will print the same string for both `a+b*(c+d)` and `(a+b)*(c+d)`. While there I also cleaned up the printing for `-a` and `a - b`. Added some tests. Pull Request resolved: https://github.com/pytorch/pytorch/pull/151920 Approved by: https://github.com/jansel |
