Making the exercises after the course¶
HPE¶
The exercise material remains available in the course archive on LUMI:
-
The PDF notes in
/appl/local/training/paow-20251022/files/LUMI-paow-20251022-Exercises_HPE.pdf -
The other files for the exercises in either a bzip2-compressed tar file
/appl/local/training/paow-20251022/files/LUMI-paow-20251022-Exercises_HPE.tar.bz2or an uncompressed tar file/appl/local/training/paow-20251022/files/LUMI-paow-20251022-Exercises_HPE.tar.
To reconstruct the exercise material in your own home, project or scratch directory, all you need to do is run:
tar -xf /appl/local/training/paow-20251022/files/LUMI-paow-20251022-Exercises_HPE.tar.bz2
in the directory where you want to work on the exercises. This will create the Exercises/HPE subdirectory
from the training project.
However, instead of running the lumi_c.sh or lumi_g.sh scripts that only work for the course as
they set the course project as the active project for Slurm and also set a reservation, use the
lumi_c_after.sh and lumi_g_after.sh scripts instead, but first edit them to use one of your
projects.
AMD¶
See the notes at each session.
There is no guarantee though that the software that is referred to on the system, will be there forever or will still work after an update of the system.
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
