GPU-only analysis
Connect host API calls to work on the device.
Open an Nsight Systems report
Pulsario reads the documented Nsight SQLite export. For .nsys-rep input it invokes your locally installed nsys export. If you already have a .sqlite export, you can open it directly without Nsight Systems installed.
pulsario report.nsys-rep
pulsario report.sqliteExplore streams and kernels
The timeline includes CUDA API calls, GPU kernels and memory copies grouped into streams, synchronization waits, NVTX ranges, and GPU metrics when those records are present in the source.
Follow launch relationships
The event inspector exposes kernel launch relationships. GPU analysis includes kernels, API activity, launch latency, and idle gaps. The website’s linked events show the idea using invented timestamps and correlation IDs.
Known limits
Availability depends on the captured data. NVTX colors and payloads are not yet imported. A report that lacks a particular metric does not gain it during import.
