I need to add a node Feature to my SLURM AWS parallel-cluster I understand from here: https://groups.google.com/g/slurm-users/c/LgL6hq3XxzE that to add a node feature permanently I have to edit slurm.conf, because the effects of the command: scontrol update NodeName=[node(s)] AvailableFeatures=[comma separated list of features] will not persist after restart (besides, I could not find how to ADD a feature without deleting the existing AvailableFeatures). However, AWS parallelcluster slurm.conf already includes files that contain lines like: NodeName=nn77[1-100] CPUs=2 RealMemory=186777 State=CLOUD Feature=dynamic,g4dn.large,gpu Weight=1000 Gres=gpu:t4:1 which is automatically generated and should not be edited. What is the recommended way to add a feature without breaking the parallelcluster set up? My I put somewhere something like NodeName=nn77[1-100] Feature+=cascadelake ? thank you!
