Elemental has very nice C++ wrappers to MPI features. If C++ is your
thing, you may want to take a look (https://github.com/elemental/Elemental/
)
There are a few other good projects you can find on GitHub that wrap MPI in
modern C++ syntax. None are complete AFAIK but I don’t think that matters

FYI: the initial C++ bindings that were proposed (by me!) to the MPI Forum were

Hello,
I would like to use openmpi with a software called LAMMPS. I know it is
possible when compiling the software to indicate it to use it with openmpi.
However when I do that I have a warning message telling me that the linkage
could not have been done (I specified the path for openmpi libra
Hi Durga,
This is only my interpretation, but they were never that appealing, nor
very C++-like, and people mostly kept using the C interface.
If you want to have a real C++ interface for MPI, have a look at Boost
MPI (http://www.boost.org/doc/libs/1_64_0/doc/html/mpi.html )
If the C++ MPI bin

I haven't used them, but at least the profiling part, and possibly

You need to configure with --enable-mpi-cxx -- the Open MPI C++ bindings are
not built by default.
Can I ask what software you are using that requires the MPI C++ bindings?
I ask because the MPI C++ bindings were deprecated in the MPI-2.2 standard in
2009, and were formally deleted from the MPI

Hello,
in a code that I am currently reading I have found that code:
template
struct MPI_Select_unsigned_integer_datatype;
template <>
struct MPI_Select_unsigned_integer_datatype<1> {
static MPI_Datatype datatype;
};
MPI_Datatype MPI_Select_unsigned_integer_datatype<1>::datatype =
MPI_UNSIG
