Current overview (not historical)

AI overview

Hugging Face Blog released a system-level profiling guide for TorchNeuron on AWS Trainium, demonstrating how to use torch.profiler with NeuronConfig to capture device and runtime traces. Using RMSNorm as an example, the guide shows how to compare CPU and Neuron device times by setting the modes parameter and enabling correlate_device_time=True to trace operations from framework scheduling to hardware execution.

    Hugging Face Profiles Inference Performance on AWS Trainium Using TorchNeuron

    Report first recorded Oct 22, 00:47

    This guide details how to systematically analyze inference performance on AWS Trainium using TorchNeuron, an open-source native PyTorch backend. It demonstrates configuring torch.profiler with the Neuron backend via NeuronConfig to capture device and runtime traces, and using Neuron Explorer to trace an operation from framework dispatch through runtime scheduling to hardware execution on a NeuronCore.
