How to use LAMMPS

Software	Version	Cluster
LAMMPS	23Jun2022	Dardel

The LAMMPS module can be loaded with

ml PDC/21.11
ml LAMMPS/23Jun2022-cpeGNU-21.11

This will add the LAMMPS bin directory to your PATH, so that LAMMPS can be started with the command lmp_mpi or lmp_omp.

Below is an example batch script for a LAMMPS job:

#!/bin/bash

# time allocation
#SBATCH -A snicYYYY-X-XX
# name of this job
#SBATCH -J lammps
# wall time for this job
#SBATCH -t 01:00:00
# partition for this job
#SBATCH -p main

# number of nodes
#SBATCH --nodes=2
# number of MPI processes per node
#SBATCH --ntasks-per-node=128

ml PDC/21.11
ml LAMMPS/23Jun2022-cpeGNU-21.11

# Run with the file infile as input and write to outfile
srun lmp_mpi < infile > outfile

This will run LAMMPS (lmp) with 256 cores (2 nodes), and will read the input specified in infile and write to outfile in the directory the job was submitted. Submit the batch script with the sbatch command, see also the How to run jobs.
