Cabana is a performance portable library for particle-based simulations. Cabana provides particle data structures, particle algorithms, and particle communication, as well as structured grids, grid algorithms, grid communication, and particle-grid algorithms. Cabana enables simulation on a variety of platforms, including multi and many-core architectures (CPUs and GPUs). Applications include but are not limited to molecular dynamics (MD) for atomic simulation, peridynamics for fracture mechanics, N-body cosmology, and various flavors of particle-in-cell (PIC) methods, including applications to fluid and solid mechanics and plasma physics.
Cabana is developed as part of the Co-Design Center for Particle Applications (CoPA) within the Exascale Computing Project (ECP) under the U.S. Department of Energy. CoPA is a multi-institutional project with developers from ORNL, LANL, SNL, LLNL, PPNL, and ANL.
