Ah! *ding* goes the memory bell.
There is, but it's an add on to SGE (freely available). Details escape me, but might be worth checking if that's present. I think YAIM, left to it's own devices sorts this out - but YAIM left to it's own devices tends to comandeer SGE, so my understanding is that it's normally throttled back.
Something along the lines of
http://gridscheduler.sourceforge.net/howto/filestaging/
http://grid.pd.infn.it/cream/field.php?n=Main.InstallationAndConfigurationNotesForCREAMUsingSGEAsBatchSystem (techincally out of date, but ...)
Not sure exactly how to check the file staging process, but hopefully that's a hint in the right direction.
