[Swift-devel] Support request: Swift jobs flooding uc-teragrid?

[Ti Leggett]

I can't say how many gram jobs can be submitted at one time or over a  
time period X. I do know that Torque and Moab can handle 1000s of jobs  
in the queue and rather quickly as well. I think you'll need to  
discover what those limits are per resource per method. For instance  
TG will have a different threshold than Teraport for instance.
