Hi, @ctueting; this is a little out of date, but still gives a reasonable idea:
Various threads throughout the forum have requested that the guide be updated with more realistic various maxima for different jobs.
But it’s a larger scale issue which is difficult to address generally, as (for example) 1050 pixel box refinements will run in NU refine on 48GB GPUs, but will demand >440GB of system RAM during various steps (usage is more reasonable throughout most of the run, but some calculations really spike RAM usage). I did post a screenshot immediately below the above post demonstrating this.
On a joint cluster, this is a recipe for disaster as I doubt most places will spec systems with 4TB+ of RAM “just in case”.
