Setting up for the exercises

During the course, you can use the training project project_465002174 for the exercises. After the course, it is still possible to make almost all exercises in your own project. They need only very little resources, but you will need both CPU and GPU resources. This project should only be used for exercises and not for your own work!

The "Object Storage" exercises in Exercise session 5 do require data in the training project, so these exercises should really be made while the training project is still active. 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 if they are not made during the second course day (the reservation expires at 6pm CET/ 7pm EET that day).

  • 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_465002174/course-20250602-$USER/Exercises
cd /scratch/project_465002174/course-20250602-$USER/Exercises

    where you have to replace project_465002174 using the number of your own project.

    If you have no other project on LUMI, you can also use the scratch of the course project project_465002174. Do use a personal subdirectory as in the following commands:

    mkdir -p /scratch/project_465002174/$USER/Exercises
cd /scratch/project_465002174/$USER/Exercises

  • Now download the exercises and un-tar:

    wget https://462000265.lumidata.eu/2day-20251020/files/exercises-20251020.tar.bz2
tar -xf exercises-20251020.tar.bz2

    Link to the tar-file with the exercises and the bzip2-compressed version.

  • You're all set to go!
