Single core based job examples

#!/bin/bash
#SBATCH --partition=hourly      # Using 'hourly' will grant higher priority
#SBATCH --ntasks-per-core=2     # Request the max ntasks be invoked on each core
#SBATCH --hint=multithread      # Use extra threads with in-core multi-threading
#SBATCH --time=00:30:00         # Define max time job will run
#SBATCH --output=myscript.out   # Define your output file
#SBATCH --error=myscript.err    # Define your error file

module purge
module load $MODULE_NAME # where $MODULE_NAME is a software in PModules
srun $MYEXEC             # where $MYEXEC is a path to your binary file
