Cabana is a performance portable library for particle-based simulations. Applications include, but are not limited to, molecular dynamics (MD) with short- and/or long-range atomic interactions; various flavors of particle-in-cell (PIC) methods, including use within fluid/solid mechanics and plasma physics; N-body cosmology simulations; and peridynamics for fracture mechanics.
Cabana provides particle data structures, algorithms, and communication, as well as structured grids, grid algorithms, and particle-grid interpolation to enable simulations on a variety of platforms including many-core CPU and GPU architectures. Cabana is built on Kokkos, with many additional optional library dependencies, including MPI for multi-node simulation.
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.
Instructions for building Cabana on various platforms, an API reference with tutorial links, and links to the Doxygen can be found in our wiki.
