Not that I know. The problem is of course that no processor will know all
boundary DoFs (because it only knows its local part of the domain) and so you
would have to merge the results of all processors -- this is not terribly
difficult (since the IndexSet class is serializable, for example) but it might
yield a very very large index set if you are working on large numbers of
processors.
My question to you would be what you want to do with the result of this
operation?
