> In {{getNodesUtilJSON()}} is only calculated for resources that are defined on a partition level. These might be the same resources as defined in the nodes or they might not be.
> When walking over the node the last node visited will ultimately set the {{resourceExists}} flag. If I have a set of 2 nodes one that has the resource GPU defined and one that has not the outcome of the call will be different for the order the nodes get visited.
> If the node with GPU is visited last the second loop will be entered with {{resourceExists}} true if it was checked first {{resourceExists}} will be false.
> That means the output of the call is unreliable, it also means that any web UI parts that display the details cannot be relied on.
