Learn Parallel Processing Programming: MPI Message Processing Computing

Simplest Introduction to MPI: MPI lets you declare the number of processes or processors and sends copies of each program to each  process or processor you declare

MPI Code Examples: Examples for each type of MPI command

MPI Send / Recv Tutorial: The Send statement sends data value(s) to a specified process. The Recv statement receives a data value from a specified process.

General Flow Chart of Parallel Processing with MPI: Summation Code of Numbers, Sample Structure of Program, stime = Wtime().  Example

// Initialize MPI environment
MPI_Init(&argc, &argv);
MPI_Comm_size(MPI_COMM_WORLD,&nproc);

MPI_Comm_rank(MPI_COMM_WORLD, &rank);

stime = MPI_Wtime(); /* start timer */

// broadcast N & data
MPI_Bcast(&N, 1, MPI_INT, 0, MPI_COMM_WORLD);

MPI_Bcast(&adata[0], n, MPI_INT, 0, MPI_COMM_WORLD);

// Master gets stop timer
etime = MPI_Wtime(); /* end time */
// everybody waits for all to arrive

MPI_Barrier(MPI_COMM_WORLD);
