Once a slurm script has been prepared for a Gurobi problem it can be submitted to the queue by running the <code>sbatch script-name.sh</code> command. The jobs status in the queue can then be checked by running the <code>sq</code> command. Sample slurm scripts for two such problems provided with each gurobi module version in the examples directory are given here: | |||
