Hi David, I am not quite sure if this is exactly what you are looking for, but we use nodes weights to prioritize "smaller" nodes over "larger" nodes for job scheduling (for our definition of "smaller" and "larger"). https://slurm.schedmd.com/slurm.conf.html#OPT_Weight For node weighting we've adapted the weight mask method as presented by Kilian Cavalotti in https://slurm.schedmd.com/SLUG19/Slurm_on_Sherlock.pdf (slides 15 and 16) and as also referred to by Ole Holm Nielsen on his Slurm web pages https://wiki.fysik.dtu.dk/niflheim/Slurm_configuration#node-weight Best regards Jürgen
