LAMMPS
LAMMPS (Large-scale Atomic/Molecular Massively Parallel Simulator) is a classical molecular dynamics code with a focus on materials modeling.
To determine the available versions of LAMMPS installed use
$ vpkg_versions lammps
The clusters may have a few versions of a lammps package available but users are cautioned: they contain only the default functionality with which the program ships. Any additional functionalities realized by enabling packages require end users (or workgroups) to build their own copies of LAMMPS. Please reference Installing and managing LAMMPS on Caviness/DARWIN as a guide through this process.
