OpenMP Tutorial Seung-Jai Min ([email protected]) ... -MPI (Distributed memory programming) OUR FOCUS. ECE 563 Programming Parallel Machines 3 Shared Memory ParallelBefore starting the tutorial, I will cover a couple of the classic concepts behind MPI’s design of the message passing model of parallel programming. The first concept is the notion of a communicator. A communicator defines a group of processes that have the ability to communicate with one another. In this group of processes, each is assigned ...

The MPI_Send and MPI_Recv functions utilize MPI Datatypes as a means to specify the structure of a message at a higher level. For example, if the process wishes to send one integer to another, it would use a count of one and a datatype of MPI_INT. The other elementary MPI datatypes are listed below with their equivalent C datatypes.
