Benchmark Suite

The GraphBrew Benchmark Suite provides automated tools for running comprehensive experiments across multiple graphs, algorithms, and benchmarks.

🚀 Quick Start

python3 scripts/graphbrew_experiment.py --full --size small          # Full pipeline
python3 scripts/graphbrew_experiment.py --train --size small         # Training pipeline
python3 scripts/graphbrew_experiment.py --size small --quick         # Quick test
python3 scripts/graphbrew_experiment.py --brute-force               # Validation

Sizes: small (16 graphs, 62MB) · medium (28, 1.1GB) · large (37, 25GB) · xlarge (6, 63GB) · all (87, 89GB). Categories include mesh, web, social, road, citation, P2P, and synthetic graphs.

Results saved to ./results/ (reorder_*.json, benchmark_*.json, cache_*.json) and weights to ./scripts/weights/active/ (type_registry.json, type_N.json).

Running Individual Phases

python3 scripts/graphbrew_experiment.py --phase reorder --size small
python3 scripts/graphbrew_experiment.py --phase benchmark --size small --skip-cache
python3 scripts/graphbrew_experiment.py --phase cache --size small
python3 scripts/graphbrew_experiment.py --phase weights

See Command-Line-Reference for all options including --min-mb, --max-graphs, --trials, --quick.

Output Format

Results are JSON arrays. See Configuration-Files for the complete schema of benchmark_*.json, cache_*.json, reorder_*.json, and type_N.json weight files.

PageRank Convergence Analysis

Analyze how reordering affects PageRank convergence.

Usage

Run PageRank directly via the binary with verbose output:

# Run PR with verbose convergence output
./bench/bin/pr -f graph.mtx -s -o 7 -n 5

Or include in the experiment pipeline:

# Run benchmarks (includes convergence data in results)
python3 scripts/graphbrew_experiment.py --phase benchmark --size small

Example Output

PageRank convergence varies by reordering algorithm:

Graph: facebook.el
┌────────────────────┬────────────┬──────────────┐
│ Algorithm          │ Iterations │ Final Error  │
├────────────────────┼────────────┼──────────────┤
│ ORIGINAL (0)       │ 18         │ 9.2e-7       │
│ HUBCLUSTERDBG (7)  │ 16         │ 8.8e-7       │
│ LeidenOrder (15)   │ 15         │ 9.1e-7       │
│ LeidenCSR (17)     │ 14         │ 8.5e-7       │
└────────────────────┴────────────┴──────────────┘

Experiment Workflow

# One-click full experiment
python3 scripts/graphbrew_experiment.py --full --size medium

For step-by-step control, see Running-Benchmarks for manual execution and Command-Line-Reference for all options.

Troubleshooting

See Troubleshooting for common issues. Quick fixes:

  • Missing graphs: --download-only --force-download
  • Memory issues: --size small or --max-mb 500
  • Timeouts: --skip-slow --skip-expensive
