Default queue resource attributes are a set of parameters that are defined in the queue configuration. These parameters are described in the queue_conf(5) man page.
You can add new resource attributes to the default attributes. New attributes are attached only to the queue instances that you modify. When the configuration of a particular queue instance references a resource attribute that is defined in the complex, that queue configuration provides the values for the attribute definition. For details about queue configuration see Configuring Queues.
For example, the queue configuration value h_vmem is used for the virtual memory size limit. This value limits the amount of total memory that each job can consume. An entry in the complex_values list of the queue configuration defines the total available amount of virtual memory on a host or assigned to a queue.
