Dear Jianwei,

The VTK SMP infrastructure abstracts the backend so you don't have to worry
about which backend to write for. See the PDF document reference in


It is up to the students to make a decision on which filters they want to
implement using this infrastructure. Once the proposals are in, we may come
back and make some suggestions for other algorithms. Also, note that the
project may include the VTK imaging pipeline as stating in "this will
include modernization of the old multi-threading code in the imaging

David: Is there a reference describing the VTK threaded image algorithm
infrastructure or do we just point to the code?
