Three-part PyTorch profiling series explains torch.profiler for accelerator debugging
RisingSayak · x · 2026-07-21
A three-part blog series on profiling in PyTorch aims to close a documentation gap around torch.profiler and help practitioners understand what is happening inside an accelerator.
The post argues that profiling is a basic skill for answering questions like:
- why a GPU/accelerator is idle,
- why a model is slower than expected,
- and what can still be optimized.
It also says the series is meant to make the community more comfortable generating and reading profile traces, since PyTorch docs felt insufficient on this topic.
