Q-Chem

Q-Chem is a comprehensive ab initio quantum chemistry software for accurate predictions of molecular structures, reactivities, and vibrational, electronic and NMR spectra.

Example script slurm-qchem-script.sh to run Q-CHEM on 1 node of the cpu partition using 1 cores and at most 4 GB of memory:

slurm-qchem-script.sh

#!/bin/bash
 
#SBATCH --time=1-00:00:00
#SBATCH --ntasks-per-node=1
#SBATCH --mem=4GB
#SBATCH --partition=cpu
#SBATCH --qos=cpu
#SBATCH --job-name=run_qchem
#SBATCH --output=%x.o%j
#SBATCH --error=%x.e%j
 
echo "JOB NAME    : $SLURM_JOB_NAME"
echo "PARTITION   : $SLURM_JOB_PARTITION"
echo "MEMORY      : $SLURM_MEM_PER_NODE MB"
echo "HOSTNAME    : $HOSTNAME"
 
module load qchem

#--------------------------------------------------------------------------------------------------------------
 
qchem $INPUT_FILE $OUTPUT_FILE

Example script slurm-qchem-multiple-script.sh to run Q-CHEM on 2 node of the cpu partition using 4 cores and at most 4 GB of memory:
