* change hook so that test still gets saved in --sc when fails in test setup (caused an off by 1 error due to setup being called before the logreport hook)
* allow reruns for all tests now that --sc is used
* increase number of reruns now that --sc is used

* add stepcurrent flag (--sc) based off the stepwise flag that saves the currently running test so that test running can resume from the last successful test after segfaults, takes in an argument for a key so that different test runs dont overwrite each other
* send sigint to process when timeout so that xml can be made
* add currently unused stepcurrent skip flag (--scs) based off stepwise skip flag that skips the failing test, was going to use if for the keep-going label but having trouble with CI

This depends on [pytest-cpp](https://github.com/pytest-dev/pytest-cpp) to discover and run C++ tests with pytest. C++ tests are built under `${WORKSPACE}/build/bin` directory and copied to the test job under the same path.
* To expose them to `run_test`, I choose to use the mock path prefix `cpp`, for example `build/bin/c10_Array_test` would be named as `cpp/c10_Array_test` and the `python test/run_test.py --cpp -i cpp/c10_Array_test` would run the test in the same way as other Python tests. I could copy them from `build/bin` to `test/cpp`, but it will be mixed with the source code and CMake file. So this looks easier
* Some executable under `build/bin` are not C++ tests, and they are exclude, for example `build/bin/torch_shm_manager`
* C++ tests need to run with pytest directly as python command doesn't understand it
* The change is gated by the new `--cpp` argument to `run_test.py`, for example `python test/run_test.py --cpp` will run all available C++ tests
* The tests can be run in parallel
* Failing tests can be retried with `--reruns=2` and `--sw`

Sharing code between the code that handles test results in parallel vs serial mode.
Note that the original version of this code had an inconsistency between the two versions where it would execute `print_to_stderr(err_message)` on every test that ran in parallel, but for serial tests it would only invoke `print_to_stderr(err_message)` if `continue_on_error` was also specified. By sharing code, this PR changes that behavior to be consistent between the two modes.
Also adding some comments.

Common advice we give for handling memory fragmentation issues is to
allocate a big block upfront to reserve memory which will get split up later.
For programs with changing tensor sizes this can be especially helpful to
avoid OOMs that happen the first time we see a new largest input and would
otherwise have to allocate new segments.
However the issue with allocating a block upfront is that is nearly impossible
to correctly estimate the size of that block. If too small, space in the block
will run out and the allocator will allocate separate blocks anyway. Too large,
and other non-PyTorch libraries might stop working because they cannot allocate
any memory.
This patch provides the same benefits as using a pre-allocating block but
without having to choose its size upfront. Using the cuMemMap-style APIs,
it adds the ability to expand the last block in a segment when more memory is
needed.
Compared to universally using cudaMallocAsync to avoid fragmentation,
this patch can fix this common fragmentation issue while preserving most
of the existing allocator behavior. This behavior can be enabled and disabled dynamically.
This should allow users to, for instance, allocate long-lived parameters and state in individual buffers,
and put temporary state into the large expandable blocks, further reducing
fragmentation.
See inline comments for information about the implementation and its limitations.

In C++ we have TORCH_LIBRARY_FRAGMENT. This PR adds the same
functionality to the Python torch.library API.
The motivation for this is: for the simple custom op API, we don't want
users to need to deal with Library objects. One way to hide this from
users is to create library fragments.
Test Plan:
- tests that you can create multiple fragments and def+impl operators on each.

This has been bugging me for a while as I'm working on these Python scripts and they are not tracked by ufmt linter. So I add these script into that linter.
```
[[linter]]

include_patterns = [
'.github/**/*.py',
'test/run_test.py',

This change should just work and not break anything as ufmt (black + usort) linter is very safe to use for standalone util scripts.

- Delete the functorch CI shard from all CI job configurations (if it exists)
- Increase the "default" shard count by 1 for each job, unless it was
previously set to 1, to accommodate the new functorch tests and not
regress time-to-signal.
- Adds a bunch of skips for ROCM and torchdynamo configurations. We can
investigate them later.
NB: I might go through some more iterations to figure out what other
skips need to be added, but this iteration of the PR seems to pass most CI.

Enables the last few files under pytest.
xdist was causing problems with `profiler/test_profiler` `test_source_multithreaded` due to creating extra threads. Luckily we don't use it so we can disable it with `-p no:xdist`, but this is incompatible with pytest-rerunfailures==10.2, so upgrade to 10.3. I'd update the windows ami but idk how.
`dynamo/test_optimizers` and `dynamo/test_repros` both had tests that used skip_if_pytest. https://github.com/pytorch/pytorch/pull/93251/files suggests that it is due to pytest assertion rewriting, so I added `PYTEST_DONT_REWRITE` to their module docstrings to prevent pytest from rewriting assertions.
Disable test by issue in `dynamo/test_dynamic_shapes` seems sane.

Enable pytest for a few unique files. pytest runs tests in a different order than unittest (but still a consistent ordering with respect to itself) and some tests change global state, causing other tests to fail.
`test_transpose_non_contiguous` in `test_torchinductor.py` gets impacted from some other test but I'm not sure which one, so my solution is to reset the metrics before the rest of the test is run.
`test_register_patterns` in `test_quantize_fx.py` adds extra keys to global variables, so remove them when the test is done via unittest's `addCleanUp` which also works on pytest.
pytest doesn't really have an equivalent for `load_tests` so change it to be like `test_jit` that imports all the classes. I also attempted to dynamically import them, but I failed.
`test_public_api_surface` in `test_fx.py` checks for a backwards compatibility classification. There is a different test in test_fx that results in `fuser_utils` being imported. pytest runs this test before `test_public_api_surface` while unittest runs it after, so pytest sees `fuser_utils` when crawling through the modules.

Run more tests through pytest.
Use a block list for tests that shouldn't run through pytest. As far as I can tell, the number of tests run, skipped, and xfailed for those not on the blocklist are the same.
Regarding the main module:
Usually tests are run in CI, we call `python <test file>`, which causes the file to be imported under the module name `__main__`. However, pytest searches for the module to be imported under the file name, so the file will be reimported. This can cause issues for tests that run module level code and change global state, like test_nn, which modifies lists imported from another file, or tests in test/lazy, which initialize a backend that cannot coexist with a second copy of itself.
My workaround for this is to run tests from the `__main__` module. However, this results in pytest being unable to rewrite assertions (and possibly other things but I don't know what other things pytest does right now). A better solution might be to call `pytest <test file>` directly and move all the code in run_tests(argv) to be module level code or put it in a hook in conftest.py.

Fixes#90940. This PR revamps how tests are run in parallel as well as device visibility at the docker container and within the run_test.py test runner.
First, running multiple test modules concurrently on the same GPU was causing instability for ROCm runners manifesting as timeouts. ROCm runners have at least 1 GPU each, but often 2 or more. This PR allows NUM_PROCS to be set equal to the number of devices available, but also takes care to set HIP_VISIBLE_DEVICES to avoid oversubscribing any GPU.
Second, we had introduced env vars `-e ROCR_VISIBLE_DEVICES` (#91031) to prepare for two GHA runners per CI node, to split up the GPU visibility at the docker level between the two runners. This effort wasn't fully realized; to date, we haven't had more than one runner per CI host. We abandon this effort in favor of all GPUs being visible to a single runner and managing GPU resources as stated above.

Rerun all disabled test to gather their latest result so that we can close disabled tickets automatically. When running under this mode (RERUN_DISABLED_TESTS=true), only disabled tests are run while the rest are skipped `<skipped message="Test is enabled but --rerun-disabled-tests verification mode is set, so only disabled tests are run" type="skip"/>`
The logic is roughly as follows, the test runs multiple times (n=50)
* If the disabled test passes, and it's flaky, do nothing because it's still flaky. In the test report, we'll see the test passes with the following skipped message:
```
<testcase classname="TestMultiprocessing" file="test_multiprocessing.py" line="357" name="test_fs" time="0.000" timestamp="0001-01-01T00:00:00">
<skipped message="{"flaky": True, "num_red": 4, "num_green": 0, "max_num_retries": 3, "rerun_disabled_test": true}" type="skip"/>
</testcase>
```
* If the disabled test passes every single time, and it is not flaky anymore, mark it so that it can be closed later. We will see the test runs and passes, i.e.
```
<testcase classname="TestCommonCUDA" name="test_out_warning_linalg_lu_factor_cuda" time="0.170" file="test_ops.py" />
```
* If the disabled test fails after all retries, this is also expected. So only report this but don't fail the job (because we don't care about red signals here), we'll see the test is skipped (without the `flaky` field), i.e.
```
<testcase classname="TestMultiprocessing" file="test_multiprocessing.py" line="357" name="test_fs" time="0.000" timestamp="0001-01-01T00:00:00">
<skipped message="{"num_red": 4, "num_green": 0, "max_num_retries": 3, "rerun_disabled_test": true}" type="skip"/>
</testcase>
```
This runs at the same schedule as `mem_leak_check` (daily). The change to update test stats, and (potentially) grouping on HUD will come in separated PRs.

This PR does a couple things to stop slow gradcheck from timing out:
- Splits out test_ops_fwd_gradients from test_ops_gradients, and factors out TestFwdGradients and TestBwdGradients which both inherit from TestGradients, now situated in common_utils (maybe there is a better place?)
- Skips CompositeCompliance (and several other test files) for slow gradcheck CI since they do not use gradcheck
- because test times for test_ops_fwd_gradients and test_ops_gradients are either unknown or wrong, we hardcode them for now to prevent them from being put together. We can undo the hack after we see actual test times are updated. ("def calculate_shards" randomly divides tests with unknown test times in a round-robin fashion.)
- Updates references to test_ops_gradients and TestGradients
- Test files that are skipped for slow gradcheck CI are now centrally located in in run_tests.py, this reduces how fine-grained we can be with the skips, so for some skips (one so far) we still use the old skipping mechanism, e.g. for test_mps

Fixes#83973 (This is a substitute PR for https://github.com/pytorch/pytorch/pull/85024)
First of all, thanks for your invaluable contributions to PyTorch everyone!
Given how extensively `torch.cuda.is_available` is used in the PyTorch ecosystem, IMHO it's worthwhile to provide downstream libraries/frameworks/users the ability to alter the default behavior of `torch.cuda.is_available` in the context of their PyTorch usage.
I'm confident there are many current and future such use cases which could benefit from leveraging a weakened, NVML-based `torch.cuda.is_available` assessment at a downstream framework's explicit direction (thanks @malfet 81da50a972 !). Though one could always patch out the `torch.cuda.is_available` function with another implementation in a downstream library, I think this environmental variable based configuration option is more convenient and the cost to including the option is quite low.
As discussed in https://github.com/pytorch/pytorch/pull/85024#issuecomment-1261542045, this PR gates new non-default NVML-based CUDA behavior with an environmental variable (PYTORCH_NVML_BASED_CUDA_CHK) that allows a user/framework to invoke non-default, NVML-based `is_available()` assessments if desired.
Thanks again for your work everyone!

run tests in parallel at the test file granularity
runs 3 files in parallel using multiprocessing pool, output goes to a file, which is then printed when the test finishes. Some tests cannot be run in parallel (usually due to lacking memory), so we run those after. Sharding is changed to attempt to mask large files with other large files/run them on the same shard.
test_ops* gets a custom handler to run it because it is simply too big (2hrs on windows) and linalg_cholesky fails (I would really like a solution to this if possible, but until then we use the custom handler).
reduces cuda tests by a lot, reduces total windows test time by ~1hr

This is a new version of #15648 based on the latest master branch.
Unlike the previous PR where I fixed a lot of the doctests in addition to integrating xdoctest, I'm going to reduce the scope here. I'm simply going to integrate xdoctest, and then I'm going to mark all of the failing tests as "SKIP". This will let xdoctest run on the dashboards, provide some value, and still let the dashboards pass. I'll leave fixing the doctests themselves to another PR.
In my initial commit, I do the bare minimum to get something running with failing dashboards. The few tests that I marked as skip are causing segfaults. Running xdoctest results in 293 failed, 201 passed tests. The next commits will be to disable those tests. (unfortunately I don't have a tool that will insert the `#xdoctest: +SKIP` directive over every failing test, so I'm going to do this mostly manually.)
