Hi, Kshitij,
Even if you fetch an array to a remote location, its access will
be guarded by the distribution of that array. If tmp(0) lives in
place 1, then accessing tmp(0) in place 1 will produce an exception.
What exactly are you trying to achieve? Do you want to have some
piece of data avaliable (i.e., replicated) in all places?
