Hi Marc

I am not a C++ programmer, I must say for starters.

The LAM MPI Tutorials have a few C++ examples,
some with non-blocking calls.
Sorry, just a few simple examples,
not "a lot of comprehensive examples" as you wish.

See (in particular Part 2 average.cc and overlap.cc):

http://www.lam-mpi.org/tutorials/nd/

There are some examples here, but they seem to use only blocking
calls, although I haven't checked them all:

http://people.sc.fsu.edu/~burkardt/cpp_src/mpi/mpi.html

In any case, it should not be too difficult to translate the existing
MPI examples written in C to C++.
You can find plenty of examples in C with non-blocking calls online.
Besides the links above, check:

I hope this helps.
