Profiling in PyTorch (Part 1): A Beginner's Guide to torch.profiler

AchievementResearchMay 29, 2026

Hugging Face researchers Aritra Roy Gosthipaty, Sayak Paul, Sergio Paniego, Rémi Ouazan Reboul, and Pedro Cuenca published a beginner's guide to torch.profiler, demonstrating profiling on matrix multiplication and addition operations using an NVIDIA A100 GPU. The guide walks readers through reading profiler tables and traces, explaining CPU and GPU lane events, and introducing torch.compile's effect on kernel fusion and CUDA launches. The series aims to lower the barrier to PyTorch performance optimization.
