What problem does it solve?
This skill provides a structured workflow to compare two Ascend Profiler runs, quantify performance deltas, and optionally trace findings back to source and PRs. The design supports evaluating prefill/decoding, kernel/op deltas, Host/sync behavior, and trace distribution to pinpoint regressions across runs.
Core Features & Use Cases
- Compare two ASCEND_PROFILER_OUTPUT directories to surface performance deltas and regressions.
- Step through sanity checks, overall metrics alignment, stage-level attribution, kernel/op dimension, API signals, and optional source/PR attribution.
- Use cases include debugging performance regressions between baseline and newer runs, attributing changes to specific modules, and generating evidence-backed reports.
Quick Start
Provide Profile A and Profile B ASCEND_PROFILER_OUTPUT directories and run the workflow to generate a comparative report.
