Verified Solution[pytorch/pytorch] torch.compile crashes on user-defined Triton kernel referencing triton.language.dtype globals
Sponsored Content
### ROOT CAUSE
The crash occurs because `torch.compile` does not properly handle user-defined Triton kernels that reference `triton.language.dtype` globals. The compiler fails to resolve these globals during the compilation process, leading to a crash. This is due to the interaction between PyTorch's compiler and the Triton JIT system, where certain global references are not recognized.
### CODE FIX
Modify the kernel to avoid using the `dtype` global from `triton.language` by passing the dtype as an argument instead. This ensures compatibility with `torch.compile`.
```python
import triton
import triton.language as tl
@triton.jit
def kernel(x, dtype: tl.dtype):
# Use the passed `dtype` argument instead of referencing the global
pass
```
This change ensures the kernel's dependencies are explicitly provided, making it compatible with `torch.compile`.
