[gridengine users] how to limit the number of job submission from users

[Park Sangmin]

Hello, my good mentors.

I'm setting up sge to start service for our cluster system.
I want to limit the number of job submission from users.
For example, I want to restrict to 2 jobs number of job submission per a user.
I tried to set it up using "to slots", but it's not enough. 
is there other option instead of slots?

this is rqs
{
   name         job_submission
   description  resourse quota for the number of job submission
   enabled      TRUE
   limit        users {@onsiteusers} queues short.q to slots=16
}
