====== Using the GWDG Scientific Compute Cluster – An Introduction ======

===== Slides =====
The slides for the course can be found {{:en:services:application_services:high_performance_computing:courses:parallelkurs.pdf|here}}.

===== Please read before watching =====
These videos were recorded a while ago and a few things have changed since then. They remain largely relevant and are still helpful today, so we'll keep them online, but please take the exact commands used, especially when [[https://docs.hpc.gwdg.de/start_here/connecting/index.html|connecting to the cluster via ssh]] with a grain of salt.
Please refer to [[https://docs.hpc.gwdg.de/|our documentation]] for up-to-date information on anything that did not work as shown in the videos.
