Scheduler tuning profile 
  1.  in cluster configuration: select global and give some functional tickets in automatic user defaults (50).
  2. in policies: set policies importance factors to 0.01 (posix priority), 0.1 (urgency) and 10 (tickets). give large amount of functional tickets to the system (100000). That's it. if you wish, users with larger/smaller importance can be defined under functional policy button with the corresponding number of tickets.
  3. To establish the order of filling the nodes with jobs (in qmon):
    1. Set Scheduler Configuration/General/Sort by sequence number
    2. In Queue control select the queue/Modify/Attributes for hosts and hostgroups/General/Set sequence number . If sequence number is the same, the load will be used to select a queue by scheduler.
