[Swift-user] job waiting

Hi Ben,
Thanks for answering my question. This phenomena occur after half an hour of execution. If all the jobs finish execution at original speed, it would probably take not more than 40 min. How the system figure out that some jobs will take more than 1 hour? Should I request more time when I execute "grid-proxy-init"?
I did not change the default throttles. How much is more appropriate? The total number of jobs in my application typically run between 4000 and 30000 and typically each job can be finished within a couple of minutes.
Chen, Yue

actually, I see you're using coasters on NCSA, so the actual numbers for
walltimes being submitted into NCSA's queueing system will be a little
strange. But my first question, that some jobs taking around an hour still

Also I notice a large number of jobs being submitted at the start of your
run - have you adjusted the default throttles on your swift installation
to some larger value?
