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. It can freely be used for scientific research.

Some of PALM's highlights are

• excellent scaling, so far tested up to 10000 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
