title: Difference between qdel and kill commands
body: <p>Are there any differences between running qdel command or kill-9  to kill a job that is running using several compute nodes on a HPC cluster?</p>
  
  <p>The effect of kill -9 seems to be immediate while qdel takes 5-10 minutes to change the job status from running (R) to canceled (C) before it stops.</p>
