Getting started
A clearer view of what your CPU and GPU are doing.
Meet Pulsario
Pulsario is a proprietary, free-to-use local trace analysis application for Linux perf.data and NVIDIA Nsight Systems reports. It reads existing profiling files and opens an analysis interface in your browser. It does not run profiling collectors.
Public release is upcoming
The public PyPI distribution is not yet available. The installation command shown on this site is the proposed release command, not an available download. The examples below describe the current application for users who already have an authorized build.
Open an existing profile
Launch Pulsario without arguments to browse for files or use drag and drop. You can also pass a CPU file, a GPU report, or both on the command line.

Not every recording contains every kind of data. Review the capability report before interpreting a timeline. Missing scheduler or counter data is reported as missing, never inferred from gaps between samples.
