From 0ad3278b12138e7b2cc3d77a0dc9ee862cf35c29 Mon Sep 17 00:00:00 2001 From: Oleksandr Bezdieniezhnykh Date: Tue, 12 May 2026 23:55:50 +0300 Subject: [PATCH] [AZ-299] C7 OnnxTrtEpRuntime: ORT + TRT EP fallback strategy Land the fallback InferenceRuntime strategy that satisfies C7-IT-05: when the TRT-direct path (AZ-298) cannot deserialise a cached engine or when the operator explicitly selects ORT, the system stays in the air at degraded latency rather than dropping the request. Conforms to the AZ-297 Protocol; current_runtime_label() == "onnx_trt_ep". Production - onnx_trt_ep_runtime.py: compile_engine is a no-op returning an EngineCacheEntry pointing at the source .onnx; deserialize_engine is gate-first for .engine entries and gate-skip for .onnx, builds an ORT InferenceSession with the provider list [TensorrtExecutionProvider, CUDAExecutionProvider, CPUExecutionProvider], stages cached engines into the ORT TRT EP cache directory via symlink-or-copy, warms up with one session.run after construction, and honours config.inference.ort_disallow_cpu_ fallback by raising EngineDeserializeError when the active provider resolves to CPU; infer emits a one-shot c7.fallback_to_onnx_trt_ep WARN log plus gcs_alert callback on first call when is_fallback= True; release_engine is idempotent. _build_provider_args is the single point that pins TRT EP option-key names (Risk-3) and caps trt_max_workspace_size at gpu_memory_budget_bytes // 4 (AC-8). - config.py: adds ort_trt_cache_dir (validated non-empty) and ort_disallow_cpu_fallback to C7InferenceConfig. - fdr_client/records.py: adds c7.fallback_to_onnx_trt_ep and c7.cpu_fallback FDR record kinds. Tests - test_onnx_trt_ep_runtime.py: covers AC-1..AC-8 + Risk-2 CPU-fallback alert + Risk-3 option-key pin + NFR-reliability error rewrap; Tier-1 via fake ORT session; Tier-2 placeholders skip on macOS dev for numerical FP16 comparison and session-creation perf NFR. - test_protocol_conformance.py: drops onnx_trt_ep from the missing- module parametrize now that the module ships. - test_az272_fdr_record_schema.py: extends per-kind fixture builder to cover the two new C7 FDR kinds in the roundtrip / schema-version AC tests. Docs - module-layout.md: replaces the pending onnx_trt_runtime row with the shipped onnx_trt_ep_runtime row + capabilities list. - batch_32_cycle1_report.md + reviews/batch_32_review.md: full batch + self-review (PASS_WITH_WARNINGS, 4 Low findings accepted). Tests run: c7_inference 139 passing + 17 Tier-2 skips; combined unit suite (excluding pending components) 529 passing, 19 env-skipped.
