Intro to Supercomputing with LUMI - Online course, December 10-11, 2024

Course organisation

  • Schedule

  • HedgeDoc for questions

  • Project for the course: project_465001603.

    This project provides resources for the exercises. The project should not be used for your own work!

  • There are two Slurm reservations for the course for the exercises on he second day:

    • CPU nodes: LUMI_Intro_small (on the small Slurm partition)
    • GPU nodes: LUMI_Intro_standard-g (on the standard-g Slurm partition)

Setting up for the exercises

During the course, you can use the training project project_465001603 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. 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. 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 5pm CET/ 6pm 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_465001603/$USER/exercises
cd /scratch/project_465001603/$USER/exercises

    where you have to replace project_465001603 using the number of your own project.

  • Now download the exercises and un-tar:

    wget https://462000265.lumidata.eu/2day-20241210/files/exercises-20241210.tar.gz
tar -xf exercises-20241210.tar.gz

    Link to the tar-file with the exercises

  • You're all set to go!
