Benchmarking

We provide benchmarks to encourage collaboration and competition in making actuarial software run faster than ever before.

Containerized benchmarks

We currently only have 1 benchmark, we are working to expand the benchmarks. Open a discussion in this repository if you have any thoughts to share.

Time measurement is currently the best of 3 runs.

Notes

• BasicTerm_ME 100 Million
  • You can find lifelib's modelpoint file with 10,000 modelpoints as model_point_table.xlsx. We use these modelpoints, but repeat them 10,000 times for 100,000,000 modelpoints.

GitHub-hosted runners

These benchmarks run in GitHub-hosted runners in GitHub actions. Used for benchmarks that are not computationally intensive.

Benchmarks in this repository:

• basic_term_benchmark: Replicate the cashflows of the LifeLib BasicTerm model
  • Python LifeLib BasicTerm_M
  • Julia using LifeSimulator
  • Python using recursive formulas with PyTorch and NumPy
  • Python using matrix operations (no recursion) on PyTorch arrays and NumPy arrays
• exposures: Create date partitions for experience studies
  • Julia ExperienceAnalysis
  • R actxps
• mortality: Read SOA mortality tables and use them in a simple calculation
  • Julia MortalityTables
  • Python Pymort

The below results are generated by the benchmarking scripts in the folders for each language. These scripts are run automatically by GitHub Actions and populate the results below.
