ProfileInsight
Find why your GPU job is slow from its profile.
ProfileInsight reads a PyTorch profiler trace (Chrome trace JSON, optionally gzip-compressed) and reports what a person would see first when reading it. It is in an early stage.
Install
pip install profileinsight
Use
profileinsight trace_rank0.json.gz
prints the analysis report of the profile:
- the cycles of the GPU timeline, such as
Timeline structure: A B^8 Cfor a setup part, eight repetitions and a tail, with the time of every repetition and how the repetitions differ from each other (src/profileinsight/cycles.py); - the bubbles, the times when no compute kernel runs, with their reasons (communication, copies, a host
synchronization, a slow host, ...), summed per repetition, and an example timeline for communication and copy
bubbles (
src/profileinsight/bubbles.py).
The rules behind each part are described at the top of its file.
Release
Pushing a tag v<version> that matches version in pyproject.toml builds the package and publishes it to PyPI through trusted publishing (.github/workflows/build.yml).
