This course is part of PRACE Advanced HPC Workshop and will be delivered as an ONLINE EVENT for remote participation
Overview
On clusters and distributed memory architectures, parallel programming with the Message Passing Interface (MPI) is the dominating programming model. This 4 half-days course teaches parallel programming with MPI starting from a beginners level. Hands-on sessions (in C, Fortran, and Python (NEW)) will allow users to immediately test and understand the basic constructs of the Message Passing Interface (MPI).
Content Levels: Beginners = 8:00h (50%) + Intermediate = 6:00h (37%) + Advanced = 2:00h (13%)
This course is a PRACE training event. It is organized by the VSC Research Center, TU Wien, in cooperation with the High-Performance Computing-Center Stuttgart (HLRS).

Course format: |
This course will be delivered as a LIVE ONLINE COURSE (using Zoom) for remote participation. |
|---|---|
|
Prerequisites: |
For the hands-on sessions you should know how to work on the Unix/Linux command line and be able to progam in either C/C++ or Fortran or Python (NEW, the exercises will also be available in Python+mpi4py+numpy. |
| Hands-on labs: | For doing the hands-on labs all you need is a C/C++ or Fortran compiler, or Python+mpi4py+numpy, and a recent MPI library. Participants can choose between using their own laptops or any system they have access to that provides these, it's even possible to do the exercises in Google Colab. Alternatively, participants can ask for a training user account at the VSC for the duration of the course. Accepted participants will be contacted a few days before the course and asked to do a short PRE-ASSIGNMENT that has to be completed before the course starts. |
