MPI Programming Howto for Beginners

To introduce how to parallelize Fortran programs using the MPI library, let us consider very simple example problems. We will see basic idea of parallelization, and actual implementation of that idea using the MPI library in example 1.

1. Example 1: 1D Diffusion Equation
   • Problem description and serial Fortran program
   • Parallelization
     • Deadlock
     • Reduction Operation
     • Derivative Type
