Octo-Tiger
From https://doi.org/10.1145/3204919.3204938:
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.
Build Status [master]
CircleCI - Basic tests:
| Simple build- and legacy tests |  |
Jenkins - All CPU / GPU node-level tests for the 8 major build configurations:
| gcc/clang, with/without-cuda, with/without-kokkos | |
| HIP + Kokkos Tests |
Jenkins - Special machine tests:
| POWER9 tests | |
| KNL Kokkos HPX Backend / SIMD tests | |
| Development environment tests | |
| HIP Development environment tests |
Notes:
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
tools/docker/base_image.
