Collection of some MPI codes

We are interested in the point to point communication in the linear network model topology using openmp.

The whole point of MPI (Message Passing Interface) is to make processes communicate. Point-to-point communication is divided into two operations: Send and Receive. Its most basic form is called blocking. Here I wrote a blocking and non-blocking mpi program in c++. communications.
