as a matter of fact, yes it wil be. sorting is inherent in domain 
decomposition, but Berk has also implemented in on single processors 
with significant speedup. Of course the output files are now in the same 
order as the input file, so there will not be any need for desorting. 
That said, it could still be useful for 3.3 users.
