There are several solution what i mostly do is. Give the desired nodes a 
property, eg: reserved

Then in toruqe make a temporary queue: (See example)
  resources_default.neednodes = reserved

only allow the user or in my example the unix group.

Submit jobs with:
   qsub -qq_genetics ....


regards



=== queue definition ====
create queue q_genetics
set queue q_genetics queue_type = Execution
set queue q_genetics acl_host_enable = False
set queue q_genetics acl_user_enable = False
set queue q_genetics resources_max.nodect = 64
set queue q_genetics resources_default.neednodes = reserverd
set queue q_genetics resources_default.nodect = 1
set queue q_genetics resources_default.nodes = 1
set queue q_genetics resources_default.walltime = 01:00:00
set queue q_genetics acl_group_enable = True
set queue q_genetics acl_groups = sara
set queue q_genetics acl_groups += genetics
set queue q_genetics acl_logic_or = True
set queue q_genetics acl_group_sloppy = True
set queue q_genetics enabled = True
set queue q_genetics started = True
