[slurm-users] sbatch and --nodes

its friday and i'm either doing something silly or have a misconfig somewhere, i can't figure out which

when i run

sbatch --nodes=1 --cpus-per-task=1 --array=1-100 --output test_%A_%a.txt --wrap 'uname -n'

sbatch doesn't seem to be adhering to the --nodes param. when i look at my output files it's spreading them across more nodes. in the simple case above it's 50/50, but if i through a random sleep in, it'll be more. and if i expand the array it'll use even more nodes. i'm using con/tres and have cr_core_memory,cr_one_core_per_task set
