• Job scripts

Job scripts are standard BASH-scripts with some extra information for the slurm job scheduler. Hence, we start with the first line of the script, telling the OS which kind of UNIX shell to use for interpreting the commands in the script.

#!/bin/bash

Then we add a series of directives for the slurm job scheduler, each starting with a '#SBATCH'. Although the '#' character usually indicates a comment, this specific string gets interpreted by slurm and allows to set various options.

#SBATCH -N 1
#SBATCH --ntasks-per-node=16
#SBATCH --ntasks-per-core=1
#SBATCH --partition=mem_0064
#SBATCH --qos=normal_0064
#SBATCH --mail-type=BEGIN,END
#SBATCH --mail-user=roland.braune@univie.ac.at
