Prerequisites and content levels

Prerequisites:

Familiarity with Linux and Linux editors is recommended.
Basics/principles of programming (in C, C++ or Fortran).
For doing the hands-on labs all you need is a C/C++ or Fortran compiler 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.
