Theoretical PBS Scheduler/Server Limits

Hello,

We are curious to know what might be the theoretical/practical limits for the Open PBS scheduler as we have a couple a few users submitting a couple of thousand jobs at a time.

Is there a known number of submitted jobs the scheduler cannot handle and would likely crash? Or if the limit is based on available hardware resources, are there formulas we could employ in determining the limit for our scheduler and/or PBS server?

Thanks,
Siji

What is your goal of such a use case ? Is there any requirements to know such a limit for your usecase ?

It would be based on your underlying capacity, speed, i/o reponse of your underlying hardware on which PBS Server is hosted. Obvisiously, if 100’s of users are continously (every second) querying the server while 100 users are submitting millions of jobs at the same would have some consequences.
