Frequently asked questions
A few things worth knowing before your first trace.
Is Pulsario free?
Yes. Pulsario is proprietary software licensed free of charge, subject to its End User License Agreement. Free to use does not mean open source.
Does Pulsario collect profiles?
No. It analyzes existing Linux perf.data and NVIDIA Nsight Systems files. Run profiling collectors separately on the system you want to study.
Does my trace leave my computer?
The application runs locally with no account or upload service. Its local server binds to 127.0.0.1 by default. The website demo uses entirely synthetic data and does not accept profiling uploads.
Do I need a GPU on the viewing machine?
Pulsario analyzes recorded files; it does not execute the captured GPU workload. Viewing can happen on a Mac or Linux workstation. Raw .nsys-rep import still requires a local Nsight Systems installation.
Is the timeline on this website a real capture?
No. It illustrates a fixed synthetic recording following the application's shared design standard. CPU ticks are sample observations; CUDA and GPU intervals represent recorded activity. It is not a live monitor and does not show invented scheduler states. File import and the actual analysis engine are not embedded in the website.
Where are PyPI and GitHub links?
Public package publication is pending. The application source is private and proprietary, so this website does not link to a public source repository.
