Q: What does a sample bsub script look like?

The following script will submit your job to queue par-multi and ask for 120 cores (i.e, -n) for a task no longer than 8.5 hrs (i.e., -W).

#!/bin/bash 
#BSUB -q par-multi 
#BSUB -n 120
#BSUB -o %J.out 
#BSUB -e %J.err 
#BSUB -W 08:30

echo "Running WRF"
mpirun ./wrf.exe
