# Job Monitoring and Management



Utilize  [hpctools - Tufts HPC Helper Tool](../examples/hpctools.md) to monitor active jobs

### Check Active Jobs

Active jobs are the jobs in the stage of R (running), PD (pending), or CG (completing). Only active jobs can be displayed in `squeue` command output.

To check your active jobs in the queue:

`$ squeue --me` or `$ squeue -u your_utln`

```bash
[tutln01@cc1gpu001 ~]$ squeue --me
             JOBID PARTITION     NAME     USER ST       TIME  NODES NODELIST(REASON) 
            296794   preempt     bash tutln01  R       5:12      1 cc1gpu001 
[tutln01@cc1gpu001 ~]$ squeue -u tutln01
             JOBID PARTITION     NAME     USER ST       TIME  NODES NODELIST(REASON) 
            296794   preempt     bash tutln01  R       5:21      1 cc1gpu001 
```

To check **details** of your **active jobs** (running or pending):

`$ scontrol show jobid -dd JOBID`

```bash
[tutln01@cc1gpu001 ~]$ scontrol show jobid -dd 296794

To cancel all of your jobs:

`$ scancel -u $USER` or `$ scancel -u your_utln`
