Profiling in PyTorch Part 2: From nn.Linear to a Fused MLP

Original: Profiling in PyTorch (Part 2): From nn.Linear to a Fused MLP

Hugging Face continues its PyTorch profiling series with a tutorial on moving from nn.Linear layers toward a fused MLP implementation.

This Hugging Face Blog post appears to be a technical tutorial in a PyTorch profiling series. From the title, it focuses on analyzing performance from basic nn.Linear operations to a fused multilayer perceptron implementation. The likely audience is ML engineers and developers interested in understanding where neural network execution time goes and how kernel fusion can improve model throughput.

This Hugging Face Blog article, titled “Profiling in PyTorch Part 2: From nn.Linear to a Fused MLP,” appears to be the second installment in a technical series about profiling PyTorch workloads. Because no article body was provided, the available facts are limited to the source, publication date, URL, and title. The safest reading is that the post is a tutorial centered on measuring and improving the performance of a multilayer perceptron-style block in PyTorch, starting from the familiar nn.Linear module and progressing toward a fused MLP implementation.
