bench-solver

Ad-hoc runtime benchmarking tool supporting model-checkers CGAAL and PRISM-games. Benchmark results for paper(pending publication) are found at results-model-checker.

Setup

  1. Install model-checkers as described by their instructions.
  2. For CGAAL, we use Rust 1.69.0 (MSRV is 1.65.0) and compile from 64624f6 with cargo build --release.
  3. For PRISM-games we compile from the 6dcd804 to include a required bugfix from the authors and follow the PRISM-games installation guide for compiling from source with PPL.
  4. Make a python3 virtual environment python3 -m venv venv and install requirements pip3 install -rrequirements.txt. Lastly source it source venv/bin/activate.
  5. Change variables in benchmark-suite.py such as which SUITE or SEARCH_STRATEGY to suit your needs.
  6. Run benchmarks by python3 benchmark-suite.py which will show the currently running benchmark, and will emit intermediate results when each test completes.
  7. When suite has been benchmarked, find resulting CSV by the following format results/$suitename-$search-strategy-$timestamp.csv.

Suites

The suites (set of tests the benchmark will run) are defined by a CSV file found in suites/ with the columns name,model,formula. Multiple suites exist for our purposes due to some benchmarks taking days to complete. The full benchmark suite for both model-checkers can be found in suites/cgaal-full.csv and suites/prism-full.csv, respectively.

Limitations

  • Measurement of memory by way of using ru_maxrss in previous tests are flawed and may be ignored. Would be nice to include this, although results upper bound on memory usage exists.
  • Very quick benchmarks (<100ms), may have noise in results. Preferably each test should be run for a minimum of some time, and the average of the completed runs be used as results.
