1. Hugging Face Publishes a Beginner’s Guide to Reading torch.profiler Traces

Hugging Face. Hugging Face published the first part of a profiling series that walks through configuring the torch.profiler.profile() context manager and interpreting both the statistical profiler table and the temporal Chrome trace. The post explains the distinction between self and total CPU/CUDA time, how to spot overhead-bound versus compute-bound kernels, the dispatch chain from aten::matmul down to aten::mm, and the roughly 2.5ms gap between CPU kernel launches and GPU execution. It also shows how torch.compile fuses operators such as torch.add(torch.matmul(x, w), b) into a single aten::addmm while adding CPU overhead per step, setting up later parts that target LLM profiling.
