[torqueusers] resources_max / resources_min

Hi all!

 I'm new to Torque, so I'm sorry if this issue have been discussed before.

I'm using Torque/Maui on a Rocks 5.0 cluster. The problem is that
resources_max / resources_min queue attributes seems to not work
correctly.

[roman at zeon ~]$ qstat -Qf PB
Queue: PB
    queue_type = Execution
    max_user_queuable = 10
    total_jobs = 1
    state_count = Transit:0 Queued:0 Held:0 Waiting:0 Running:1 Exiting:0
    max_running = 2
    acl_host_enable = False
    acl_hosts = compute-3-29,compute-3-19,compute-3-9,compute-3-28,compute-3-18,
        compute-3-8,compute-3-27,compute-3-17,compute-3-7,compute-3-26,
        compute-3-16,compute-3-6,compute-3-25,compute-3-15,compute-3-5,
        compute-3-24,compute-3-14,compute-3-4,compute-3-23,compute-3-13,
        compute-3-3,compute-3-22,compute-3-12,compute-3-2,compute-3-31,
        compute-3-21,compute-3-11,compute-3-1,compute-3-30,compute-3-20,
        compute-3-10,compute-3-0
    resources_max.nodes = 16
    resources_max.pmem = 1800mb
    resources_max.walltime = 400:00:00
    resources_min.nodes = 16
    resources_default.nodes = 16
    mtime = 1213180918
    resources_assigned.nodect = 0
    max_user_run = 1
    enabled = True
    started = True

[roman at zeon ~]$ qsub -q PB -I -l nodes=1
qsub: Job exceeds queue resource limits MSG=cannot satisfy queue min
nodes requirement
[roman at zeon ~]$ qsub -q PB -I -l nodes=2
qsub: waiting for job 586.zeon.xray.lab to start
qsub: job 586.zeon.xray.lab ready

---------------------------------------------------------
Job 586.zeon.xray.lab started execution on node compute-3-15.local at
Thu Jun 12 17:08:06 EEST 2008
Job was selected from queue PB
Assigned nodes:
compute-3-15
compute-3-14
Total CPUs assigned: 2
---------------------------------------------------------
[roman at compute-3-15 ~]$

So, the PB queue (I guess) should accept jobs only for 16 nodes. It
does not accept job on 1 node, but accepts on 2 nodes, and also on 17
CPUs.

Thanks for your help!
 Roman Zubatyuk.
