Helpers for dealing with MPI.
Basically there are two helpers available:
Example of who to use these classes:
A program that is parallel if compiled with MPI and sequential otherwise:
If one wants to have sequential program even if the code is compiled with mpi then one simply has to exchange the typedef with
.
For checking whether we really use MPI or just fake please use MPIHelper::isFake (this is also possible at compile time!)
