lbmpy: Automatic code generation for efficient parallel lattice Boltzmann methods

•In this article we present a meta-programming system for lattice Boltzmann methods similar to what FEniCS is for finite element methods.•Our tool can automatically generate highly efficient, MPI parallel CPU and GPU code for a wide range of lattice Boltzmann algorithms including multi-relaxation-time, cumulant, and entropic schemes. The generated compute kernels obtain excellent performance and scaling results, demonstrated on the SuperMUC-NG supercomputing system.
