Do you mean just specifying a different GRAM (eg gt4) in the job
submission file or is there some extra setup that is required ?

Thanks,

I don't have an idea about this one, and I suspect you'll have better
luck with it in a Condor forum.  I am surprised, however, because I know
that in their architecture there's a separate daemon called the GAHP
they use to offload their interactions with things like Globus into a
separate daemon.  The only thing I can think to suggest is to look if a
GAHP is up and running at the time you experience this problem and try
killing it.

This has to do with the architecture of GRAM2.  It polls for job  
completion, and does so at a one minute interval.  Condor-G is  
meddles with it to try to improve things, which I believe is the  
poll_fast output you're seeing.  It sounds like the poll_fast isn't  
speeding things up, and you're instead getting the default one-minute  
interval polling.  If you set up the more recent implementation of  
GRAM, which also works with Condor, you will get near-instantaneous  
notification of job completion.
