Making the exercises after the course

The "Object Storage" exercises in Exercise session 5 do require data in the training project but there is an alternative set of exercises missing only one element from the during-the-course version that can be made in your own project. For the exercises from Exercise session 4 you can no longer use the reservation.

  • Create a directory in the scratch of your project, or if you want to keep the exercises around for a while, in a subdirectory of your project directory or in your home directory (though we don't recommend the latter). Then go into that directory.

    E.g., in the scratch directory of your project:

    mkdir -p /scratch/project_46YXXXXXX/course-20260422-$USER/Exercises
cd /scratch/project_46YXXXXXX/course-20260422-$USER/Exercises

    where you have to replace project_46YXXXXXX using the number of your own project.

  • Now install the exercise files:

    tar -xf /appl/local/training/2day-20260422/files/exercises-20260422.tar.bz2

  • You're all set to go!

Warning

The software and exercises were tested thoroughly at the time of the course. LUMI however is in continuous evolution and changes to the system may break exercises and software
