High Level Design

The Omniperf Tool is architecturally composed of three major components, as shown in the following figure.

  • Omniperf Profiling: Acquire raw performance counters via application replay based on rocProf. The counters are stored in a comma-separated format, for further analysis. A set of MI200 specific micro benchmarks are also run to acquire the hierarchical roofline data. The roofline model is not available on earlier accelerators.

  • Omniperf Grafana Analyzer:

    • Grafana database import: All raw performance counters are imported into the backend MongoDB database for Grafana GUI analysis and visualization. Compatibility of previously generated data between Omniperf versions is not necessarily guaranteed.

    • Grafana GUI Analyzer: A Grafana dashboard is designed to retrieve the raw counters info from the backend database. It also creates the relevant performance metrics and visualization.

  • Omniperf Standalone GUI Analyzer: A standalone GUI is provided to enable performance analysis without importing data into the backend database.
