How can I check the status of my jobs?

Historically check jobs with:
sacct -u $USER -S YYYY-MM-DD -o jobid,submit,start,end,elapsed,state

Note: instead of a date you can supply now-24hours to -S

To get a list of all format fields type:
sacct --helpformat

For current queued and running jobs, you can find the job with:
squeue -u $USER -l

To obtain information about a running job, such as the running node, type:
jobinfo -v JOBID

To examine the resource usage of the job, ssh into that node with:
ssh COMPUTE_NODE

Then run htop. See https://htop.dev/

For GPU jobs, you can use nvtop and nvidia-smi

For current queued and running jobs
squeue --me
scontrol show job <jobid>
