Single Node Jobs

To request a whole node for a job, use --exclusive option, without requesting any memory (slurm will assign all available memory to the job). Combine with --constraint option, user can request a specify type of single node to run a job. This is a sample sbtach script which request a farm18 node to run a single node job.
#!/bin/bash
#SBATCH --nodes=1
#SBATCH --exclusive
#SBATCH --job-name=xxx
#SBATCH --partition=production
#SBATCH --account=xxx
#SBATCH --constraint=farm18
