Non actionable perf hint: reduction over non-contiguous dims
Labels: triaged, enhancement, oncall: pt2, module: inductor

### 🐛 Describe the bug

This is the exact same repro as https://github.com/pytorch/pytorch/issues/103715 but a different issue

When using SAM with SDPA and torch.compile I get this perf hint coming from `torch/_inductor/codegen/triton.py`

```
reduction over non-contiguous dims
reduction over non-contiguous dims
```

But it doesn't really tell me what I can change in my model code to fix this or which line of code in my program is causing this


## Setup

```
pip install git+https://github.com/cpuhrsch/saf.git@msaroufim/sdpa
pip3 install --pre torch torchvision torchaudio --index-url https://download.pytorch.org/whl/nightly/cu121
pip install nvtx
wget https://gist.githubusercontent.com/msaroufim/1002c17469fc670fc5af27dda12fa7e4/raw/c22a381f359da08c7efb4c87959efbd00f688bac/benchmark_segment_anything.py
```

## Command

```
python benchmark_segment_anything.py --model_type "vit_h" --checkpoint_path "/data/home/vasiliy/cluster/sam_dataset/sam_vit_h_4b8939.pth" --compiled 1  --profile 0 --max_batch_size 30 --block_only 0 --quantized 0
```

## Logs

OOM issue was reported seperately

If reserved but unallocated memory is large try setting max_split_size_mb to avoid fragmentation.  See documentation for Memory Management and PYTORCH_CUDA_ALLOC_CONF
