I think printing the GRES usage for nodes is a neat idea.  So I've added 
a flag "-G" to my pestat command so that the GRES usage for each job on 
each node is printed.  The squeue command can print GRES usage using -o %b.

Could you give pestat a try to see if it fits your needs:

Just run "pestat -G" on your Slurm cluster.

At the moment pestat doesn't print a column of total configured GRES in 
the node, but this could be added if there is interest.

Please send me feedback and comments about pestat.
