Introduction to the Message Passing Interface

Course Overview

The Introduction to the Message Passing Interface (MPI) course provides an overview of the MPI standard with a view to its application to scientific / engineering problems. Throughout the course, the basic concepts behind the message passing paradigm are discussed together with code examples. Course attendees will take part in practicals where they will have the the opportunity to explore motivational examples in C or Fortran using one of the ICHEC systems.

Learning Outcomes

After the course, attendees should

  • Understand the key concepts behind MPI
  • Have an overview of the functionality the interface provides
  • Know how to implement a simple parallel program using MPI
  • Know how to compile and run an MPI program on one of the ICHEC systems

Pre-requisites

To benefit from this course attendees should have:

  • An interest in High Performance Computing
  • Completed the ICHEC introduction to HPC Course if they have no prior HPC experience
  • Basic Linux/UNIX skills
  • Programming experience in at least one of Fortran, C or C++
