GitHub issuesOct 8 `[Inductor][CUDA] FTZ on subnormal inputs causes O(1) errors in ceil(float32) and atan2(bfloat16)`### 🐛 Describe the bug On CUDA, Inductor's default flush-to-zero (FTZ) flushes subnormal **inputs** to (signed) zero before the operation, which turns mathematically correct **normal-scale** outputs into wrong ones. Unlike the "a subnormal output is flushed" cases, here the...pytorch/pytorch · tinywisdomOpen ↗GitHub issuesOct 8 [inductor][cutlass] Missing device_type silently selects the CUDA path in CUTLASS codegen...compiled, and the stack trace points at `build/.../*.cpp` rather than at inductor - very hard to attribute. 2. **EVT `trace()`** (`torch/_inductor/codegen/cutlass/lib_extensions/evt_extensions.py`) `trace()` derives `arch_prefix = "xe" if device_type == "xpu" else "sm"`.
