For now, using "universe=globus" in your submit file is equivalent to 
doing universe = grid with the gt2 grid_type.   But this backwards 
compatibility 'feature' may certainly go away, as doing 
"universe=globus" has been deprecated.  Best to move over to using the 
universe=grid syntax as soon as convenient.
