From 56f92f3659d77aa2372f86e43a8466ed030fef4e Mon Sep 17 00:00:00 2001 From: skal Date: Sun, 8 Feb 2026 13:05:15 +0100 Subject: feat(tools): Add effect depth analysis to seq_compiler Adds --analyze flag to seq_compiler to identify performance bottlenecks by analyzing how many effects run simultaneously at each point in the demo. Features: - Samples timeline at 10 Hz (every 0.1s) - Counts overlapping effects at each sample point - Generates histogram of effect depth distribution - Identifies bottleneck periods (>5 concurrent effects) - Reports max concurrent effects with timestamps - Lists top 10 bottleneck peaks with effect names Analysis Results for Current Demo (demo.seq): - Max concurrent effects: 11 at t=8.8s - 28 bottleneck periods detected (>5 effects) - 29.6% of demo has 7+ effects running (critical) - Most intensive section: 8b-12b (4-6 seconds) Most Used Effects: - GaussianBlurEffect: ~10 instances (optimization target) - HeptagonEffect: ~9 instances - ThemeModulationEffect: ~7 instances Usage: ./build/seq_compiler assets/demo.seq --analyze ./build/seq_compiler assets/demo.seq --analyze --gantt-html=out.html Files Modified: - tools/seq_compiler.cc: Added analyze_effect_depth() function - EFFECT_DEPTH_ANALYSIS.md: Detailed analysis report + recommendations - timeline_analysis.html: Visual Gantt chart (example output) This helps identify: - Which sequences have too many overlapping effects - When to stagger effect timing to reduce GPU load - Which effects appear most frequently (optimization targets) Next steps: Profile actual GPU time per effect to validate bottlenecks. --- timeline_analysis.html | 425 +++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 425 insertions(+) create mode 100644 timeline_analysis.html (limited to 'timeline_analysis.html') diff --git a/timeline_analysis.html b/timeline_analysis.html new file mode 100644 index 0000000..92e4a3f --- /dev/null +++ b/timeline_analysis.html @@ -0,0 +1,425 @@ + + + + +Demo Timeline - BPM 120 + + + +
