== Introduction ==

Welcome to the HPC.NRW OpenMP Online Tutorial!

Using the [[MPI | Message Passing Interface (MPI)]] is the de-facto standard for parallel distributed-memory programming. MPI defines an API for portable and scalable process-based parallelism.

== How to proceed through this tutorial? ==

This tutorial is targeted for novice HPC developers as an initial introduction to distributed-memory programming with MPI.

The tutorial is made up of several sections, each covering a separate stand-alone topic, but they are designed to be worked through '''in order'''.

Each tutorial consists of a '''short video''', followed by a couple of quiz questions for a self control. Everything in the tutorial is platform-independent and works with every operating system with an OpenMP-compatible compiler available. Although most examples are written in C/C++, the fundamental concepts also work with Fortran.

If you have any questions or encounter problems, you can contact us via e-mail at [mailto:tutorials@hpc.nrw tutorials@hpc.nrw].

== Who created this tutorial? ==

This tutorial has been developed within the framework of the [https://hpc.dh.nrw/ HPC.NRW] project. It is part of a [[:Category:Tutorials|series of online tutorials]] on various HPC-related topics, all of which were created by HPC.NRW members.

The initial online course is based on the in-person MPI courses developed at the IT Center of RWTH Aachen University. The speaker is '''Dr. Marc-André Hermanns''' from RWTH Aachen University. Marc-André works at the university's IT center and has been an active member of the MPI Forum for many years.
