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?
