slurm job scheduler sacct show only pending and running jobs no prolog

I am quite new to slurm. I am looking on how to display ONLY current running and pending jobs, no prolog.

> sacct -s PD,R 
       JobID    JobName  Partition    Account  AllocCPUS      State ExitCode 
------------ ---------- ---------- ---------- ---------- ---------- -------- 
5049168       SRR600493    general cluster_u+          1    RUNNING      0:0 
5049168.0        prolog            cluster_u+          1  COMPLETED      0:0

Why is it printing the prolog and what the prolog is?

When you submit a job with slurm there are two things that happen. First, it allocates resources and then when you launch something on this resource, it creates a step.

So the two lines you are showing belong to the same job. The first line is the allocation and the second is the first step. So someone launched a step with a binary named prolog, this step is now finished but the allocation of the resource is not released. The user probably ran salloc first and then srun.

If you think that nobody launched a binary named prolog it's maybe that you have configured a prolog on slurm to be run at each first step of a job.

You should use squeue for that, rather than sacct. squeue will list running and pending jobs, and will be able to display more information (requested resources, etc.) than sacct. And squeue will not show job steps (like 'prolog' here)
