PALM - A PArallelized Large-Eddy Simulation Model for Atmospheric and Oceanic Flows

PALM is a large-eddy simulation (LES) model for atmospheric and oceanic flows which is especially designed for performing on massively parallel computer architectures. PALM is free software. It can be redistributed and/or modified under the terms of the GNU General Public License (v3).

Some of PALM's highlights are

  • excellent scaling, so far tested up to 32000 cores
  • online data analysis (during model runs) in order to avoid I/O bottlenecks
  • topography realized on cartesian grid (allows for steep topography)
  • non-cyclic horizontal boundary conditions including turbulent inflow
  • code can be switched to ocean version with salinity equation and equation of state for seawater
  • embedded parallelized Lagrangian particle model for various applications (footprint calculation, simulation of cloud droplet growth, visualization, etc.)
  • interface which allows users to plug in their own code extensions without modifying the default code
  • advanced shell scripts for installing and running the code in interactive and batch mode are available
  • code is permanently maintained and improved by the PALM group and other users; code management is based on subversion
