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").


For node weighting we've adapted the weight mask method as presented
by Kilian Cavalotti in 


(slides 15 and 16) and as also referred to by Ole Holm Nielsen on his
Slurm web pages 


Best regards
