All C++ MPI specialists, which relevance has the MPI C++ binding of Boost ( http://www.boost.org/ )? In the actual version 1.35 http://www.boost.org/users/news/version_1_35_0 one can find a "C++-friendly interface to the standard Message Passing Interface". The comment from boost: "Although there exist C++ bindings for MPI, they offer little functionality over the C bindings." Is there any knowledge of whether in real C++ programming, whether the official C++ MPI binding or the C++ boost MPI binding is more often used in the C++ community? For me, the answer may have implications on how separate or integrated additional bindings should be integrated into the language independent text of the MPI standard. Best regards Rolf PS: As non-C++-specialist, this question is based on a question from Martin Bernreuther. The citations are from him.
