Recently I submitted a message to torque user group but found that my question 
is actually related to maui. Here is the problem:
With two stations (server+worker) each has 16 cores, I want to submit a job but 
don't want to explicitly mention on which station. 
If I use "nodes=2:ppn=4", then 4 cores on each station is devoted. That is 
If I use "ncpus=18", I expect that maui put 16 processes on one station and 2 on 
the other automatically. However the actual result is that my job is deferred.
Total Tasks: 1  Req[0]  TaskCount: 1  Partition: ALL Network: [NONE]  Memory >= 
0  Disk >= 0  Swap >= 0 Opsys: [NONE]  Arch: [NONE]  Features: [NONE] Dedicated 
Resources Per Task: PROCS: 17 NodeCount: 1   IWD: [NONE]  Executable:  [NONE] 
Bypass: 0  StartCount: 0 PartitionMask: [ALL] Flags:       RESTARTABLE  job is 
deferred.  Reason:  NoResources  (cannot create reservation for job '152'  
(intital reservation attempt) ) Holds:    Defer  (hold reason:  NoResources) PE:  
17.00  StartPriority:  1 cannot select job 152 for partition DEFAULT (job hold 

How can I fix that?
