Summary:
- Added 2D-Convolution NHWC support
- on ROCm 4.3, with `PYTORCH_MIOPEN_SUGGEST_NHWC=1` flag
- May need to force MIOpen to search for solutions ( see examples below for flags )
**PYTORCH_MIOPEN_SUGGEST_NHWC Environment Flag**
MIOpen does not officially support NHWC yet, although convolution support has been added to tip-of-tree of MIOpen. This flag is intended to be a short-lived flag to explicitly turn on NHWC support until ROCm officially supports NHWC and performance is verified.
**Examples**
1. Example usage 1 : Run test on ROCm4.3
`PYTORCH_TEST_WITH_ROCM=1 PYTORCH_MIOPEN_SUGGEST_NHWC=1 MIOPEN_FIND_ENFORCE=4 MIOPEN_DEBUG_CONV_GEMM=0 MIOPEN_FIND_MODE=1 pytest test_nn.py -v -k "test_conv_cudnn_nhwc" `
2. Example usage 2: Run the following with `PYTORCH_MIOPEN_SUGGEST_NHWC=1` on ROCm4.3.
```
#!/usr/bin/env python3
import torch
model = torch.nn.Conv2d(8, 4, 3).cuda().half()
model = model.to(memory_format=torch.channels_last)
input = torch.randint(1, 10, (2, 8, 4, 4), dtype=torch.float32, requires_grad=True)
input = input.to(device="cuda", memory_format=torch.channels_last, dtype=torch.float16)
# should print True for is_contiguous(channels_last), and strides must match NHWC format
print(input.is_contiguous(memory_format=torch.channels_last), input.shape, input.stride() )
out = model(input)
# should print True for is_contiguous(channels_last), and strides must match NHWC format
print("Contiguous channel last :", out.is_contiguous(memory_format=torch.channels_last), " out shape :", out.shape, "out stride :", out.stride() )
```

Summary:
We currently build breakpad from [this fork](https://github.com/driazati/breakpad) to include extra logic to restore signal handlers that were previously present. With some [new additions](https://github.com/google/breakpad/compare/main...driazati:main) this fork now includes a CMake based build, so we can add breakpad as a proper dependency rather than rely on including it in Docker images as a system library which is error prone (we have a bunch of images) and hard to extend to MacOS / Windows. This also includes some changes to the crash handling code to support MacOS / Windows in a similar way to Linux.
```python
import torch
# On Windows this writes crashes to C:\Users\<user>\AppData\pytorch_crashes
# On MacOS/Linux this writes crashes to /tmp/pytorch_crashes
torch.utils._crash_handler.enable_minidumps()
# Easy way to cause a segfault and trigger the handler

The goal here is to enable opt-asan for "spawn" based unit tests since
this works for "spawn" unlike "dev-asan". As a result, we can run ASAN for
"spawn" unit tests as well.
This means we can completely remove fork unit tests from the code base since
the only purpose for these tests was to run ASAN.

Pull Request resolved: https://github.com/pytorch/pytorch/pull/62686
Test Plan:
1. Check out this PR and run `python setup.py install`.
2. The test we will be running requires CUDA. If you don't have CUDA, you can try this on another device or simply comment out the skipIf statement before the `test_jit_cuda_extension` test in `test_cpp_extensions_jit.py`
3. Run: `IN_CI=1 python test/run_test.py -i test_cpp_extensions_jit -- -k test_jit_cuda_extension` and notice that it should skip. If it doesn't skip, edit test/.pytorch-disabled-tests.json: modify the platforms list of the first issue (61655) to include whatever platform you are on (macos or linux), and just run `python test/test_cpp_extensions_jit.py -v -k test_jit_cuda_extension --import-disabled-tests` to make sure it skips.
4. Now `export PYTORCH_IGNORE_DISABLED_ISSUES=61655` or `export PYTORCH_IGNORE_DISABLED_ISSUES=34952,61655`.
5. `rm test/.pytorch-*` to clear the cached files.
6. Run the same command as in step 5 and note that it SHOULDN'T skip. It should run.

Summary:
Adds a new `ModuleInfo`-based test to `test_modules.py`.
The test passes `device` and `dtype` to each module during instantiation, ensuring that the kwargs are applied to any newly-created parameters or buffers. Note that the `device` and `dtype` kwargs should only be present when a module creates parameters or buffers; the test uses some mock magic to identify this.

Summary:
This creates `torch.cuda.set_warn_on_synchronization()` function that would warn or error when synchronizing operation is performed. We could wrap it in a context manager for ease of use, but it would be a lie, because it sets global, and not thread-local state. Since it's intended for debugging, maybe that's ok though.
As all `torch.cuda.*` functions, it's going through CPython, not pybind, so the argument is converted to long before being passed to c10 function. I'll make python argument a python enum class, but without pybind it'll still have to go thourgh long conversion.
For a test script
```
import torch
torch.cuda.set_warn_on_synchronization(1)
x=torch.randn(10, device="cuda")
x.nonzero()
y=torch.randn((), device="cuda")
if y:
print("something")
torch.multinomial(x.abs(), 10, replacement=False)
torch.randperm(20000, device="cuda")
ind = torch.randint(10, (3,), device="cuda")
mask = torch.randint(2, (10,), device="cuda", dtype=torch.bool)
val = torch.randn((), device="cuda")
x[mask]=1.
x[mask] = val
torch.cuda.synchronize()
```
the output is
```

### Remaining Tasks
- [ ] Collate results of benchmarks on two Intel Xeon machines (with & without CUDA, to check if CPU throttling causes issues with GPUs) - make graphs, including Roofline model plots (Intel Advisor can't make them with libgomp, though, but with Intel OpenMP).
### Summary
1. This draft PR produces binaries with with 3 types of ATen kernels - default, AVX2, AVX512 . Using the environment variable `ATEN_AVX512_256=TRUE` also results in 3 types of kernels, but the compiler can use 32 ymm registers for AVX2, instead of the default 16. ATen kernels for `CPU_CAPABILITY_AVX` have been removed.
2. `nansum` is not using AVX512 kernel right now, as it has poorer accuracy for Float16, than does AVX2 or DEFAULT, whose respective accuracies aren't very good either (#59415).
It was more convenient to disable AVX512 dispatch for all dtypes of `nansum` for now.
3. On Windows , ATen Quantized AVX512 kernels are not being used, as quantization tests are flaky. If `--continue-through-failure` is used, then `test_compare_model_outputs_functional_static` fails. But if this test is skipped, `test_compare_model_outputs_conv_static` fails. If both these tests are skipped, then a third one fails. These are hard to debug right now due to not having access to a Windows machine with AVX512 support, so it was more convenient to disable AVX512 dispatch of all ATen Quantized kernels on Windows for now.
4. One test is currently being skipped -
[test_lstm` in `quantization.bc](https://github.com/pytorch/pytorch/issues/59098) - It fails only on Cascade Lake machines, irrespective of the `ATEN_CPU_CAPABILITY` used, because FBGEMM uses `AVX512_VNNI` on machines that support it. The value of `reduce_range` should be used as `False` on such machines.
The list of the changes is at https://gist.github.com/imaginary-person/4b4fda660534f0493bf9573d511a878d.
Credits to ezyang for proposing `AVX512_256` - these use AVX2 intrinsics but benefit from 32 registers, instead of the 16 ymm registers that AVX2 uses.
Credits to limo1996 for the initial proposal, and for optimizing `hsub_pd` & `hadd_pd`, which didn't have direct AVX512 equivalents, and are being used in some kernels. He also refactored `vec/functional.h` to remove duplicated code.
Credits to quickwritereader for helping fix 4 failing complex multiplication & division tests.
### Testing
1. `vec_test_all_types` was modified to test basic AVX512 support, as tests already existed for AVX2.
Only one test had to be modified, as it was hardcoded for AVX2.
2. `pytorch_linux_bionic_py3_8_gcc9_coverage_test1` & `pytorch_linux_bionic_py3_8_gcc9_coverage_test2` are now using `linux.2xlarge` instances, as they support AVX512. They were used for testing AVX512 kernels, as AVX512 kernels are being used by default in both of the CI checks. Windows CI checks had already been using machines with AVX512 support.
### Would the downclocking caused by AVX512 pose an issue?
I think it's important to note that AVX2 causes downclocking as well, and the additional downclocking caused by AVX512 may not hamper performance on some Skylake machines & beyond, because of the double vector-size. I think that [this post with verifiable references is a must-read](https://community.intel.com/t5/Software-Tuning-Performance/Unexpected-power-vs-cores-profile-for-MKL-kernels-on-modern-Xeon/m-p/1133869/highlight/true#M6450). Also, AVX512 would _probably not_ hurt performance on a high-end machine, [but measurements are recommended](https://lemire.me/blog/2018/09/07/avx-512-when-and-how-to-use-these-new-instructions/). In case it does, `ATEN_AVX512_256=TRUE` can be used for building PyTorch, as AVX2 can then use 32 ymm registers instead of the default 16. [FBGEMM uses `AVX512_256` only on Xeon D processors](https://github.com/pytorch/FBGEMM/pull/209), which are said to have poor AVX512 performance.
This [official data](https://www.intel.com/content/dam/www/public/us/en/documents/specification-updates/xeon-scalable-spec-update.pdf) is for the Intel Skylake family, and the first link helps understand its significance. Cascade Lake & Ice Lake SP Xeon processors are said to be even better when it comes to AVX512 performance.
Here is the corresponding data for [Cascade Lake](https://cdrdv2.intel.com/v1/dl/getContent/338848) -
The corresponding data isn't publicly available for Intel Xeon SP 3rd gen (Ice Lake SP), but [Intel mentioned that the 3rd gen has frequency improvements pertaining to AVX512](https://newsroom.intel.com/wp-content/uploads/sites/11/2021/04/3rd-Gen-Intel-Xeon-Scalable-Platform-Press-Presentation-281884.pdf). Ice Lake SP machines also have 48 KB L1D caches, so that's another reason for AVX512 performance to be better on them.
### Is PyTorch always faster with AVX512?
No, but then PyTorch is not always faster with AVX2 either. Please refer to #60202. The benefit from vectorization is apparent with with small tensors that fit in caches or in kernels that are more compute heavy. For instance, AVX512 or AVX2 would yield no benefit for adding two 64 MB tensors, but adding two 1 MB tensors would do well with AVX2, and even more so with AVX512.
It seems that memory-bound computations, such as adding two 64 MB tensors can be slow with vectorization (depending upon the number of threads used), as the effects of downclocking can then be observed.

* [x] Test the reference checks for multiple ops. (also decide a list of different and eligible ops for this)
* [x] Handle possible edge cases (for example: `uint64` isn't implemented in PyTorch but is there in NumPy, and this needs to be handled -- more on this later) -- _Update_: We decided that these reference tests should only test for values and not types.
* [x] Create a sample PR for a single (of all different categories?) on adding reference functions to the eligible ops. -- _Update_: This is being done in this PR only.
* [x] ~Remove reference tests from `test_unary_ufuncs.py` and test to make sure that nothing breaks.~ (*Update*: We won't be touching Unary Ufunc reference tests in this PR)
* [x] Add comments, remove unnecessary prints/comments (added for debugging).
Note: To keep the PR description short, examples of edge cases encountered have been mentioned in the comments below.

Summary:
During development it is common practice to put `type: ignore` comments on lines that are correct, but `mypy` doesn't recognize this. This often stems from the fact, that the used `mypy` version wasn't able to handle the used pattern.
With every new release `mypy` gets better at handling complex code. In addition to fix all the previously accepted but now failing patterns, we should also revisit all `type: ignore` comments to see if they are still needed or not. Fortunately, we don't need to do it manually: by adding `warn_unused_ignores = True` to the configuration, `mypy` will error out in case it encounters an `type: ignore` that is no longer needed.

Summary:
Implements an idea by ngimel to improve the performance of `torch.flip` via a clever hack into TI to bypass the fact that TI is not designed to work with negative indices.
Something that might be added is vectorisation support on CPU, given how simple the implementation is now.
Some low-hanging fruits that I did not implement:
- Write it as a structured kernel
- Migrate the tests to opinfos
- Have a look at `cumsum_backward` and `cumprod_backward`, as I think that they could be implemented faster with `flip`, now that `flip` is fast.
**Edit**
This operation already has OpInfos and it cannot be migrated to a structured kernel because it implements quantisation
Summary of the PR:
- x1.5-3 performance boost on CPU
- x1.5-2 performance boost on CUDA
- Comparable performance across dimensions, regardless of the strides (thanks TI)
- Simpler code

Summary:
There are two main changes here:
- THPVariable will actually visit their grad_fn if there are no other reference to the c++ Tensor and no other reference to the grad_fn. The critical observation compared to the existing comment (thanks Ed!) is that if we also check that the c++ Tensor object is not referenced somewhere else, we're sure that no one can change the grad_fn refcount between the traverse and the clear.
- THPVariable don't need a special clear for this new cases as we're the only owner of the c++ Tensor and so the cdata.reset() will necessarily free the Tensor and all its resources.
The two tests are to ensure:
- That the cycles are indeed collectible by the gc

Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/52659
**Summary**
This commit adds `torch._C.ScriptDict`, a dictionary type that has reference
semantics across the Python/TorchScript boundary. That is, modifications
made to instances of `torch._C.ScriptDict` in TorchScript are visible in
Python even when it is not returned from the function. Instances can be
constructed by passing an instance of a Python dictionary to
`torch.jit.script`. In the case of an empty dictionary, its type is
assumed to be `Dict[str, Tensor]` to be consistent with the handling of
empty dictionaries in TorchScript source code.
`torch._C.ScriptDict` is implemented using a modified version of pybind's `stl_bind.h`-style bindings attached to `ScriptDict`, `ScriptDictIterator` and `ScriptDictKeyIterator`, wrapper classes around `c10::impl::GenericDict` and `c10::impl::GenericDict::iterator`. These bindings allow instances of `torch._C.ScriptDict` to be used as if it were a regular `dict` Python. Reference semantics are achieved by simply retrieving the `IValue` contained in `ScriptDict` in `toIValue` (invoked when converting Python arguments to `IValues` before calling TorchScript code).
**Test Plan**
This commit adds `TestScriptDict` to `test_list_dict.py`, a set of tests
that check that all of the common dictionary operations are supported
and that instances have reference semantics across the
Python/TorchScript boundary.

Summary:
This PR adds a note to the documentation that torch.svd is deprecated together with an upgrade guide on how to use `torch.linalg.svd` and `torch.linalg.svdvals` (Lezcano's instructions from https://github.com/pytorch/pytorch/issues/57549).
In addition, all usage of the old svd function is replaced with a new one from torch.linalg module, except for the `at::linalg_pinv` function, that fails the XLA CI build (https://github.com/pytorch/xla/issues/2755, see failure in draft PR https://github.com/pytorch/pytorch/pull/57772).

Summary:
Downloading slow_test list on SC causes timeout, this is even a bigger issue since `common_utils.py` is reused in many internal projects/modules.

Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/55237
In this PR, we reenable fast-gradcheck and resolve misc issues that arise:
Before landing this PR, land #55182 so that slow tests are still being run periodically.
Bolded indicates the issue is handled in this PR, otherwise it is handled in a previous PR.
**Non-determinism issues**:
- ops that do not have deterministic implementation (as documented https://pytorch.org/docs/stable/generated/torch.use_deterministic_algorithms.html#torch.use_deterministic_algorithms)
- test_pad_cuda (replication_pad2d) (test_nn)
- interpolate (test_nn)
- cummin, cummax (scatter_add_cuda_kernel) (test_ops)
- test_fn_gradgrad_prod_cpu_float64 (test_ops)
Randomness:
- RRelu (new module tests) - we fix by using our own generator as to avoid messing with user RNG state (handled in #54480)
Numerical precision issues:
- jacobian mismatch: test_gelu (test_nn, float32, not able to replicate locally) - we fixed this by disabling for float32 (handled in previous PR)
- cholesky_solve (test_linalg): #56235 handled in previous PR
- **cumprod** (test_ops) - #56275 disabled fast gradcheck
Not yet replicated:
- test_relaxed_one_hot_categorical_2d (test_distributions)

Summary:
Under this setting the job should run 3 times a day.
When the environment variable, `PYTORCH_TEST_WITH_SLOW_GRADCHECK` is set to `ON`, set the default value for `fast_mode` in gradchack wrapper as False. This would be overriden by whatever value the user explicitly passes in.
