As a noob, I have access to supercomp with SLURM. The squeue command gives the list of used nodes for various jobs of different users. A small example is given below.

Why do some users e.g. user1 (that's actually me) have one line (see below), while almost all other users have hundreds of lines (below is just a very small excerpt from user2, he/she has a lot more)?

I understand that reason is probably that all of them are actually different jobs (with different JOBID), but I am curious is this example of the right usage of resources?

  JOBID PARTITION     NAME     USER ST       TIME  NODES NODELIST(REASON)
3227434 partiti_1 jobname1     user1  R      30:53     20 node[101-110,170-179]

Thanks!
