Molecular Dynamics Simulation Sofware

LAMMPS is a classical molecular dynamics code, and an acronym for Large-scale Atomic/Molecular Massively Parallel Simulator.

LAMMPS has potentials for solid-state materials (metals, semiconductors) and soft matter (biomolecules, polymers) 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.

For further information, please visit LAMMPS website.

#

   # To run lammps, you need to provide an input script for example "in.script" and also a a data file that your input script needs to read to start the simulation. In the following example, "16" is the number of cores requested.

mpirun -n 16 -envall lmp_mpi < in.script

<code bash>

  • LSF considerations (e.g. bsub example): an example of a script for job submission
  • #!/bin/bash #BSUB -J lammps-test #jobname #BSUB -o test.log #BSUB -e test.err ##BSUB -q short #BSUB -q nodeshort #BSUB -W 300 #runtime in min #BSUB -n 64 # Store working directory to be safe SAVEDPWD=`pwd` # We define a bash function to do the cleaning when the signal is caught cp ${SAVEDPWD}/in.fene1000x10 /jobdir/${LSB_JOBID}/ cp ${SAVEDPWD}/data.file /jobdir/${LSB_JOBID}/ cd /jobdir/${LSB_JOBID} mpirun -n 64 -envall lmp_mpi <in.fene1000x10 mv -f *.* ${SAVEDPWD}

you can submit the job as bsub < lammps_job.sh
