stereomatching 17 Posting Whiz in Training

I am studying CH4.3.2 of the book "C++ concurrency in action" , the book mention about
"synchronizing with message passing" and give the reader some basic idea about it but
without details(how to implement it).

Could I find some simple examples which implement MPI by boost::thread? Since I haven't
grasp the ideas of concurrency programming yet, I hope this example could as easier as
possible and base on boost::thread.

When I was finding a simple example of MPI, I find boost::MPI 5 minutes ago, is this
MPI same as the MPI I mention above?

Thanks a lot
