# Octo-Tiger
[](https://www.codacy.com/gh/STEllAR-GROUP/octotiger?utm_source=github.com&utm_medium=referral&utm_content=STEllAR-GROUP/octotiger&utm_campaign=Badge_Grade) [](https://github.com/STEllAR-GROUP/octotiger/actions/workflows/cff-validator.yml) [](https://zenodo.org/badge/latestdoi/73526736)
From :
> Octo-Tiger is an astrophysics program simulating the evolution of star systems
> based on the fast multipole method on adaptive Octrees. It was implemented using
> high-level C++ libraries, specifically HPX and Vc, which allows its use on
> different hardware platforms.
