Prerequisites

For the hands-on sessions you should know how to work on the Unix/Linux command line and be able to program in either C/C++ or Fortran.

Content levels

• Beginner: 8 hours
• Intermediate: 6 hours
• Advanced: 2 hours

Learn more about course curricula and content levels.

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.
