3e7a66fae1 [BugFix][Refactor] fix several instances which use f = open(...) without a corresponding f.close() (#167423)
This pattern can lead to potential file descriptor leaks, which can cause resource exhaustion or other unpredictable issues

c73a92fbf5 [BE][CI] bump ruff to 0.9.2: multiline assert statements (#144546)
Reference: https://docs.astral.sh/ruff/formatter/black/#assert-statements

> Unlike Black, Ruff prefers breaking the message over breaking the assertion, similar to how both Ruff and Black prefer breaking the assignment value over breaking the assignment target:
>
> ```python
> # Input
> assert (
>     len(policy_types) >= priority + num_duplicates
> ), f"This tests needs at least {priority+num_duplicates} many types."
>
>
> # Black
> assert (
>     len(policy_types) >= priority + num_duplicates
> ), f"This tests needs at least {priority+num_duplicates} many types."
>
> # Ruff
> assert len(policy_types) >= priority + num_duplicates, (
>     f"This tests needs at least {priority + num_duplicates} many types."
> )
> ```

b346e99376 remove fast_flush arguments (#135387)
I've removed them from upstream Triton in https://github.com/triton-lang/triton/pull/4485. It looks like most places in the code use the default value of `fast_flush=True` anyway, though there are two PRs from @pearu that use `False`. To my knowledge, there's no reason to use the `False` value.

5cb05a82b4 [BC breaking] move benchmarking + prefer inductor path (#132827)
move benchmarking out of `torch._inductor.runtime.runtime_utils` and into `torch._inductor.runtime.benchmarking`, and prefer this path over directly accessing Triton's benchmarking

973037be6a [BE][Easy] apply autofix for ruff rules unnecessary-collection-call (C408): list() / tuple() / dict() (#130199)
This PR changes the empty collection factory call to Python literals:

- `list()` -> `[]`
- `tuple()` -> `()`
- `dict()` -> `{}`

The Python literals are more performant and safer. For example, the bytecode for building an empty dictionary:

```bash
$ python3 -m dis - <<EOS
import collections

d1 = {}
d2 = dict()

dict = collections.OrderedDict
d3 = dict()
EOS
```

```text
  0           0 RESUME                   0

  1           2 LOAD_CONST               0 (0)
              4 LOAD_CONST               1 (None)
              6 IMPORT_NAME              0 (collections)
              8 STORE_NAME               0 (collections)

  3          10 BUILD_MAP                0
             12 STORE_NAME               1 (d1)

  4          14 PUSH_NULL
             16 LOAD_NAME                2 (dict)
             18 CALL                     0
             26 STORE_NAME               3 (d2)

  6          28 LOAD_NAME                0 (collections)
             30 LOAD_ATTR                8 (OrderedDict)
             50 STORE_NAME               2 (dict)

  7          52 PUSH_NULL
             54 LOAD_NAME                2 (dict)
             56 CALL                     0
             64 STORE_NAME               5 (d3)
             66 RETURN_CONST             1 (None)
```

The dict literal `{}` only has one bytecode `BUILD_MAP`, while the factory call `dict()` has three `PUSH_NULL + LOAD_NAME + CALL`. Also, the factory call is not safe if users override the `dict` name in `locals` or `globals` (see the example of replacing with `OrderedDict` above).

cf6041e942 Use weakref in storing tensors as keys (follow-up to #111470) (#112076)
This PR addresses the discussion items in https://github.com/pytorch/pytorch/pull/111470#discussion_r1369008167, that is,
- use weakref when storing tensors as keys,
- add `storage_offset` to the key data,
- and revise the description of the `TensorAsKey` utility.

6382011843 Add NVIDIA A100 optimized meta parameters to bsr_dense_mm (#111760)
As in the title.

The figures below illustrate the performance differences of bsr_dense_mm with optimized parameters and bsr_dense_mm with default parameters (GPU: NVIDIA A100-SXM4-80GB). The first figure represents the performance equilibrium point in BSR tensor sparsity at which value bsr_dense_mm have the same performance characteristics as torch.matmul. The second figure represents speedups from using optimized meta parameters in bsr_dense_mm at its performance equilibrium points with respect to bsr_dense_mm with default meta parameters.

In sum, this PR speeds up `bsr_dense_mm` about 50 % depending on the bsr tensor shape and blocksize and lowers the performance equilibrium points of BSR tensor sparsity and strided tensor for matmul operations.

d4708a6da7 Add scatter_mm and bsr_scatter_mm operations. (#110396)
This PR introduces `scatter_mm` operation (compute `mm` of arbitrary pairs of tensors given in batches of tensors) that is used to implement `bsr_scatter_mm` that is equivalent to `bsr_dense_mm` (the `mm` operation on bsr and strided tensors). The implementation is provided both in Triton (when tensor dimensions are multiples of 16) and in PyTorch (otherwise).

The figures below illustrate the performance differences of `bsr_scatter_mm` and `bsr_dense_mm` (GPU: `NVIDIA GeForce RTX 2060 SUPER`). The first figure represents the performance equilibrium point in BSR tensor sparsity at which value `bsr_scatter_mm` or `bsr_dense_mm` have the same performance characteristics as `torch.matmul`. The second figure represents speedups from using `bsr_scatter_mm` at its performance equilibrium points with respect to `bsr_dense_mm`.

The same figures for GPU card `NVIDIA A100-SXM4-80GB`:

In sum:
- `bsr_scatter_mm` is about 2x faster than `bsr_dense_mm` for small block sizes of 16 and 32 and large tensors [GPU: `NVIDIA GeForce RTX 2060 SUPER`].
- `bsr_scatter_mm` is up to 2x faster than `bsr_dense_mm` for small block sizes of 16 and large tensors [GPU: `NVIDIA A100-SXM4-80GB`].
- `bsr_dense_mm` is up to 20 % faster than `bsr_scatter_mm` for block sizes of 64 or larger [GPU: `NVIDIA GeForce RTX 2060 SUPER`].
- However, `bsr_dense_mm` fails with `OutOfResources` exception for block sizes of 256 or larger whereas `bsr_scatter_mm` succeeds.
