LAMMPS on Caviness

A template Slurm job submission script for batch LAMMPS jobs is available at /opt/templates/slurm/applications/lammps.qs. Copy and edit the template based on your job's resource needs; the comments in the template describe each Slurm option and environment variable present.

At the very least, the LAMMPS input file variable must be altered accordingly:

#
# [EDIT] Indicate your LAMMPS input file (mandatory)
#
LAMMPS_INPUT="in.indent"

Also keep in mind, the default version of LAMMPS is loaded via VALET in the job submission script template and the default version may change over time based on new releases and bug fixes that indicate an older version should no longer be used. Below is the VALET command specified in the job submission script template

#
# [EDIT] Load some version of LAMMPS into the job environment
#
vpkg_require lammps/default

Based on the versions of LAMMPS available from vpkg_versions lammps, we might see something like this

$ vpkg_versions lammps
 
Available versions in package (* = default version):
 
[/opt/shared/valet/2.1/etc/lammps.vpkg_yaml]
lammps                 Molecular Dynamics Simulator
  12Dec2018:intel,mkl  release 12Dec2018 (Intel compilers, MPI, MKL FFT, USER-INTEL, USER-OMP)
  13Mar2018            release 13Mar2018 (system compilers, MPI, FFTW3)
* 13Mar2018:intel      release 13Mar2018 (Intel compilers, MPI, FFTW3)
  13Mar2018:intel,mkl  release 13Mar2018 (Intel compilers, MPI, MKL FFT)
  28Jun2014            release 28Jun2014 (system compilers, MPI, FFTW3)
  28Jun2014:intel      release 28Jun2014 (Intel compilers, MPI, FFTW3)
  28Jun2014:intel,mkl  release 28Jun2014 (Intel compilers, MPI, MKL FFT)

if we want to specify the 28Jun2014:intel,mkl instead of the default version (13Mar2018:intel) indicated by the *, then we would change the job submission script to the following

#
# [EDIT] Load some version of LAMMPS into the job environment
#
vpkg_require lammps/28Jun2014:intel,mkl

The job submission script template sources an external script to complete the setup of the job environment. You should never delete parts of the template or comment out any option unless you see [EDIT] instructions.
