      - so use walltime to use more time
  - qsub -l nodes=1:ppn=2 job.script
    - run the script in a node and using two core processers
  - qsub -l nodes=4:ppn=31,vmem=100gb -l walltime=20:00:00 jobscript.script
    - if use multi commands, use -l to separate the argument
- qstat
  - qstat -a
    - display all job
  - qstat -n
