<pre wrap="">You're right. I was trying to say that fundamentally the problem of
uncertainty in queue times will remain by virtue of the fact that the
times when people submit jobs (as well as the amount of jobs) is
unpredictable and it can affect other people's job queue times.
The predictor in the paper answers the question "if you were to submit
your job before the state of the queue changes in any way, what would be
the expected queue time for the job" and not "what will be the queue
time for the job".

Yes, its possible that between a query of prediction, and actual
submission, the state of the queues change, and therefore the actual
result change. But, every prediction comes with some error bounds, so
its possible that the change in queue state, might be reflected in the
error bars. Nevertheless, I think it might be an interesting
improvement to the current Swift scheduler. Ben, was this on the list
of Google summer of code projects? If not, perhaps you might want to
add it.<br>
