I've briefly looked at that before and would have wished there was a solution 
which the user herself could set.

However, I don't think this will help me much, as the user's job will copy 
data to the local node which should take a couple of minutes and then should 
run for 1-2 hours on this data. With concurrency limits I will only limit the 
total number of jobs as I still cannot tell Condor that only the copying job 
needs to be limited, not the CPU intensive follow-up job, right?

Thus with concurrency limits I would maybe prevent an inrush at the start of a 
job cluster, but when most nodes are busy with CPU, no more network I/O 
intensive jobs would be able to run even if some CPU cores were idle as the 
limit has been reached.

Do you agree?

Cheers
