I suppose it's a pretty trivial question but nevertheless, I'm looking for the (sacct I guess) command that will display the CPU time and memory used by a slurm job ID.

If your job is finished, then the sacct command is what you're looking for. Otherwise, look into sstat. For sacct the --format switch is the other key element. If you run this command:

sacct -e

you'll get a printout of the different fields that can be used for the --format switch. The details of each field are described in the Job Account Fields section of the man page. For CPU time and memory, CPUTime and MaxRSS are probably what you're looking for. cputimeraw can also be used if you want the number in seconds, as opposed to the usual Slurm time format.

sacct --format="CPUTime,MaxRSS"
