[torqueusers] calculating cpu time

This is a basic question but I seem to be getting conflicting answers
When defining a queue in qmgr setting resources_max.cput = 24:00:00
should set the maximum amount of cpu time a job can have right? Is this
a per CPU setting or a general cpu time setting? Meaning if I submit a
job to 16 processors should it run for 1.5 hours (24hours/16processors)
or will it run for 24 hours on each cpu?
I have gotten conflicting answers to this question.
And what if any relation does resources_max.wallclock have to this
issue? I was under the impression that wallclock time meassured the time
from when a job was submitted to when it terminated. If you set
resources_max.wallclock = 48:00:00 a job could be in the system for 48
hours in what ever stat E Q R... but that 48 hours after it was
submitted it was going to get terminated by the scheduler/resource manager.
Is this correct?
