Another issue with MPI versions is that Boost.MPI currently uses
functions such as MPI_Address that have been removed in MPI 3.0. Is
that something that should be addressed in the future? I think the
replacements for some of them did not exist before MPI 2.0.
A valid point - we will have to provide two implementations depending on
which version of MPI is present. Is there any standardized macro that
one an check to determine the MPI version at compile time?
There are MPI_VERSION and MPI_SUBVERSION, but those are in 2.0 and above
only as well. You can probably use their being undefined to mean that the
implementation does not comply to 2.0. I don't know how many 1.1-only MPI
implementations are around anymore, though; there may not be any still in
use (MPI 2.0 was released in 1997).
