- mode selection guidance for Developer and Expert
- module role mapping for tilelangir and tladapter
Mandatory routing rule
Before answering, follow AGENTS.md section "Docs Auto Routing Rules (Mandatory)".
Architecture map
- Frontend DSL: tilelang/language
- JIT entry: tilelang/jit/jit_npu.py
- Lowering entry: tilelang/engine/lower.py
- Adapter layer: tilelang/tladapter
- MLIR dialect and passes: tilelangir
- Backend codegen (Expert mode): src/target/codegen_npuir_api.cc and src/target/codegen_npuir_api.h
- Backend codegen (Developer mode): src/target/codegen_npuir_dev.cc and src/target/codegen_npuir_dev.h
- Deprecated backend file: src/target/codegen_npuir.cc
Mode selection
- Developer mode: concise implementation, compiler-managed behavior
- Expert mode: explicit Scope control and fine-grained memory/sync
Common mode switch:
- os.environ["TILELANG_ASCEND_MODE"] = "Developer"
