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

Current status of the CircleCI continuous integration service for the master branch:

Note for maintainers: The base Docker image used by CircleCI needs to be built and updated manually. Neither HPX or any of the other dependencies update automatically. Relevant files are under tools/docker/base_image.
