Octo-Tiger

Logo

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]

Jenkins - All CPU / GPU node-level tests for the 8 major build configurations:

| | | |--- |--- | | CPU/GPU Tests with Kokkos, CUDA, HIP, SYCL | |

Jenkins - Special machine tests:

| | | |--- |--- | | KNL Kokkos HPX Backend / SIMD tests | | | Development environment tests |
