You can do either

- synchronization between multiple views by hand, just like
examples/filters/fmultiple_manual.c
- synchronization between multiple views through filters with
explicit submission of synchronization between views, just like
examples/filters/fmultiple_submit.c
- starting with the future StarPU 1.3, synchronization between multiple
views through filtesr with implicit submission, just like 
examples/filters/fmultiple_submit_implicit.c

You do not need specific data interfaces for these: they are still
matrices.
