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 23Jun2022

• Using the foss/2022a toolchain

This version was compiled with the foss/2022a toolchain (GNU 1.3.0 compilers and OpenMPI 4.1.4) and it is installed in /apps/eb/LAMMPS/23Jun2022-foss-2022a-kokkos

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

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

ml LAMMPS/23Jun2022-foss-2022a-kokkos

Example of shell scripts to run LAMMPS on the batch queue:

To use version 23Jun2022 with the foss-2022a toolchain

To run lmp version 23Jun2022 as a parallel job, using e.g. 2 node2 and 16 cores per node (sub.sh)

#!/bin/bash
#SBATCH --job-name=lammpsjob          # Job name
#SBATCH --partition=batch             # Partition (queue) name
#SBATCH --nodes=2                     # Number of nodes
#SBATCH --ntasks=32                   # Number of MPI ranks
#SBATCH --ntasks-per-node=16          # How many tasks on each node
#SBATCH --cpus-per-task=1             # Number of cores per MPI rank 
#SBATCH --mem-per-cpu=600mb           # Memory per processor
#SBATCH --time=02:00:00               # Time limit hrs:min:sec
#SBATCH --output=%x.%j.out            # Standard output log
#SBATCH --error=%x.%j.err             # Standard error log

cd $SLURM_SUBMIT_DIR

ml LAMMPS/23Jun2022-foss-2022a-kokkos

srun lmp -in file.in > file.out

Note: Here file.in and file.out are only sample filenames for the input parameters and the output file. Other parameters of the job, such as the maximum wall clock time, maximum memory, the number of nodes and cores per node, and the email address need to be modified appropriately as well.
