What is the purpose of using the Boost.MPI library? Does it increase performance? And what is the difference between it and the MPICH library?
Boost.MPI provides
It intends
but not to actually improve the performance of MPI; it can’t, because it’s still tied to existing MPI implementations (though it may implement some high-level patterns in a more efficient way than you would write them, depending on how much of an MPI expert you are). It’s mainly more convenient than the regular C API.
