We set an node property and we create a queue that require that node 
property and in in maui we do reservation with the same node property.
Then this nodes are only accessable when you specify that node property 
or if you specify the queue name it only rin on the nodes that are 
reserved for that queue, eg:

node property: bioasp (for some nodes)
create queue q_bioasp
set queue q_bioasp queue_type = Execution
set queue q_bioasp acl_host_enable = False
set queue q_bioasp resources_max.nodect = 1
set queue q_bioasp resources_default.neednodes = bioasp
set queue q_bioasp resources_default.nodect = 1
set queue q_bioasp resources_default.nodes = 1
set queue q_bioasp enabled = True
set queue q_bioasp started = True

SRCFG[q_bioasp]        STARTTIME=0:00:00 ENDTIME=24:00:00
SRCFG[q_bioasp]        PERIOD=INFINITY
SRCFG[q_bioasp]        CLASSLIST=q_bioasp
SRCFG[q_bioasp]        NODEFEATURES=bioasp
