Most programs written for distributed memory, parallel computers utilize the Message Passing Interface (MPI) to exchange data or messages among processes.
MPI derived datatype provides a powerful method to define arbitrary collections of noncontiguous data in memory and to enable the noncontiguous data movement.
In this tutorial we will describe what the derived datatypes are and when/how to use them.
