We introduce a new computer code, Octo-tiger/HPX. Octo-tiger/HPX simulates classically self-gravitating hydrodynamic fluids on an adaptive mesh refinement (AMR) grid. It is particularly suited for modeling interacting binary star systems. To that end, Octo-tiger/HPX uses special techniques to ensure the conservation of linear momentum, angular momentum, and energy to machine precision. Octo-tiger/HPX makes use of the new distributed C++ runtime system, High Performance Para$\|$eX, to enable execution on massively parallel computers.
