NVIDIA adds Global Performance Tuner to TensorRT 11.1 to expand build routes
A Part 1 blog post introduces TensorRT's Global Performance Tuner, released in TensorRT 11.1, which provides customizable build routes and an accuracy-aware tuning workflow that expands the compiler's solution space and validates candidate engines against end-to-end accuracy and performance. The article frames compilation as a builder/search problem, explains the tuner's three guiding principles, and points readers to documentation and a forthcoming Part 2 covering algorithm and architecture details.
KEY POINTS
- A Part 1 blog post introduces TensorRT's Global Performance Tuner, released in TensorRT 11.1, which provides customizable build routes and an accuracy-aware tuning workflow that expands the compiler's solution space and validates candidate engines against end-to-end accuracy and performance.
- The article frames compilation as a builder/search problem, explains the tuner's three guiding principles, and points readers to documentation and a forthcoming Part 2 covering algorithm and architecture details.
- Expanding build routes and validating complete engines end-to-end addresses heuristic sprawl and makes TensorRT tuning more robust across diverse models and deployment environments.
WHY IT MATTERS
Expanding build routes and validating complete engines end-to-end addresses heuristic sprawl and makes TensorRT tuning more robust across diverse models and deployment environments.
SOURCES & TIMELINE
1NVIDIA TensorRT builds inference engines by making interdependent scheduling decisions across graph transformations, fusion, implementation selection, memory placement, and quantization. A mathematical framework models compilation as a builder algorithm generating candidate solutions and a searching algorithm selecting the fastest feasible one under accuracy constraints. The Global Performance Tuner, released in Te…
The Global Performance Tuner in TensorRT 11.1 represents alternative scheduling strategies as explicit, searchable build routes composed of compiler knob combinations. TensorRT exposes C++ APIs to apply a fixed build route, inspect the current route, and discover the full tunable configuration space of more than 200 knobs with their allowed values and defaults. trtexec implements a tuning loop that expands a route …
