Performance Optimization With Profiling Insights

via “model profiling and performance analysis with per-operator timing”

Cross-platform ML inference accelerator — runs ONNX models on any hardware with optimizations.

Unique: Implements a lightweight profiler (onnxruntime/core/framework/profiler.cc) that instruments operator kernel execution with timing hooks, collecting per-operator execution time, memory allocation, and provider-specific metrics. Results are exported as structured JSON enabling programmatic analysis and visualization.

vs others: More integrated than external profiling tools (NVIDIA Nsight, Intel VTune) because profiling is built-in and doesn't require separate tools, and more detailed than PyTorch's profiler (which lacks per-operator memory tracking) because ORT tracks both timing and memory per operator.
