The "pestat" tool can tell you the CPUload of nodes belonging to a job:

pestat -j jobid

Get pestat from 
https://github.com/OleHolmNielsen/Slurm_tools/tree/master/pestat

The "psjob" tool prints the processes on nodes of a given job when 
executed on the control node:

psjob jobid

get psjob and other tools from
