TensorRT

As explained in LLMs in Production

TensorRT is NVIDIA software for optimizing and executing machine-learning inference on NVIDIA GPUs.

TensorRT turns a trained model into an NVIDIA GPU-specific inference engine. It combines graph optimization, INT8 quantization, and memory techniques to reduce runtime cost, but the resulting engine must match the hardware where it will run. section 6.1.1

A practical TensorRT workflow typically involves:

  • Loading a PyTorch model and representative input, then tracing it into TorchScript so its operations can be optimized. section 6.1.1
  • Defining static or dynamic input shapes and datatypes in torch_tensorrt before compilation. section 6.1.1

How LLMs in Production covers it

How deep it goes
Explains graph optimization, quantization, memory techniques, tracing, input shapes, and hardware-specific compilation without detailing the full compiler.
Examples
Uses a GPT-2 PyTorch model, traced tokens, configurable shapes, and an NVIDIA Docker container.
What it assumes
Assumes familiarity with PyTorch models, tensors, and GPU execution while demonstrating tracing and input configuration.
What you can do after
Apply it via torch_tensorrt to compile a traced PyTorch model for specified NVIDIA GPU hardware.
How it connects
Connects model compilation with graph optimization, quantization, TorchScript, PyTorch, Docker, and GPU inference.
