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.
| Simple build- and legacy tests |
| gcc/clang, with/without-cuda, with/without-kokkos |
| POWER9 tests | |
| KNL Kokkos HPX Backend / SIMD tests | |
| Development environment tests |
CircleCI note for maintainers: The base Docker image used by CircleCI needs to be built and updated manually. Neither HPX nor any of the other dependencies update automatically. Relevant files are under
