about queues

[elham9449]

Hi all,
I had a few questions regarding how to use Torque scheduler. Assume [if required] that we have the required permissions [admin, etc.] of a cluster.

1. How can we define a maximum wait time for a job before execution (when it is in the queue?)

2. If a job has reached its maximum wait time (for a certain queue), can we change its current queue specified by the user in job script?

3. Can we define a parameter that does not allow users or specific jobs to be executed in a particular queue?

4. Is there a way to find out automatically the elapsed time of a certain job (by using qstat or other tools)?

Thank you very much in advance for your help.
