Description
In source:services/api/config/application.default.yml, the explanation of max_compute_nodes is wrong. It suggests that it limits how many nodes will be created, but it doesn't. The correct value is more like "something much bigger than node manager's max-nodes config."
Install docs should recommend TreeWidth=65533 in slurm.conf.
In source:services/nodemanager/doc/gce.example.cfg the max_nodes comment is a copy-paste fail. Others aren't as bad, but they should all say something like "Before raising this, ensure API server's max_compute_nodes config is much larger than the new value, and restart API server if needed to ensure it is using its new config."
# Node Manager will not start any compute nodes when at least this
# running at all times. By default, these will be the cheapest node size.
max_nodes = 8
