Description

From http://lammps.sandia.gov/ : "LAMMPS is a classical molecular dynamics code, and an acronym for Large-scale Atomic/Molecular Massively Parallel Simulator.

LAMMPS has potentials for soft materials (biomolecules, polymers) and solid-state materials (metals, semiconductors) and coarse-grained or mesoscopic systems. It can be used to model atoms or, more generically, as a parallel particle simulator at the atomic, meso, or continuum scale.

LAMMPS runs on single processors or in parallel using message-passing techniques and a spatial-decomposition of the simulation domain. The code is designed to be easy to modify or extend with new functionality. "

Version 3Mar2020

• Using the foss/2019b toolchain

This version was compiled with the foss/2019b toolchain (GNU 8.3.0 compilers and OpenMPI 3.1.4) and it is installed in /apps/eb/LAMMPS/3Mar2020-foss-2019b-Python-3.7.4-kokkos/

The binary is called lmp and it was compiled with the following packages:

   'ASPHERE', 'BODY', 'CLASS2', 'COLLOID', 'COMPRESS', 'CORESHELL', 'DIPOLE',
   'GRANULAR', 'KIM', 'KSPACE', 'MANYBODY', 'MC', 'MESSAGE', 'MISC',
   'MOLECULE', 'MPIIO', 'PERI', 'POEMS', 'PYTHON', 'QEQ', 'REPLICA', 'RIGID',
   'SHOCK', 'SNAP', 'SPIN', 'SRD', 'VORONOI',

   'EFF', 'FEP', 'H5MD', 'LB', 'MANIFOLD', 'MEAMC', 'MESO', 'MGPT', 'MISC',
   'MOFFF', 'MOLFILE', 'NETCDF', 'PHONON', 'PLUMED', 'PTM', 'QTB', 'REAXC',
   'SMD', 'SMTBQ', 'SPH', 'TALLY', 'UEF', 'YAFF'

To use this version of Lammps, first load the modules with

ml LAMMPS/3Mar2020-foss-2019b-Python-3.7.4-kokkos

The name of the binary is lmp and it does not work on the AMD Opteron processors. To exclude these processors, please add the following line in your job submission script:

#SBATCH --constraint=EDR
