Cabana is a performance portable library for particle-based simulations. Applications include but are not limited to Molecular Dynamics (MD) with either short- and/or long-range interactions and various flavors of Particle-in-Cell (PIC) methods, including applications to fluid and solid mechanics and plasma physics. Cabana provides particle data structures, algorithms, and utilities to enable simulations on a variety of platforms including many-core architectures and GPUs.
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.
Information on how to configure, build, and test Cabana on a variety of different computing platforms.
The Cabana programming guide covers core library concepts and directed examples of using the library API.
The Cabana library builds in AOSOA (array-of-struct-of-array) as the basic memory layout of particle data structure.
The Cabana library is built on the Kokkos library, which is a C++ Performance Portability Programming EcoSystem.
Breakdown of basic programming constructs for portable on-node parallelism.
The goal of benchmarks is to ensure high performance of the library infrastructure.
