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

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. > Problem 2 > ========= > When we submit a job to the master node it gets there and runs as you > would expect and then exits, however on the submission node the job > appears idle until about a minute after the job has actually finished > (on short jobs lasting 10 secs, we have not really tried any long ones > yet), it then shows status as running (which takes several times > the job > actually took to run) and then exits. 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.
