====== Using the GWDG Scientific Compute Cluster – An Introduction ====== \\ This is a very old introduction to our HPC system. A lot has changed since then. \\ The basic principles still apply, so we kept this up for reference, but most names, \\ especially hostnames, names of partitions, etc. have changed and are no longer valid. \\ \\ Please take a look at our [[https://docs.hpc.gwdg.de/start_here/index.html|current documentation]] for up-to-date information. ===== 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. {{http://wwwuser.gwdg.de/~parallel/scc-course/connecting-to-frontends.webm}} ==== Important Linux Commands ==== {{http://wwwuser.gwdg.de/~parallel/scc-course/introduction-linux.webm}} ==== Specifics of the GWDG Cluster ==== {{http://wwwuser.gwdg.de/~parallel/scc-course/specifics-of-gwdg-cluster.webm}} ==== Modules ==== {{http://wwwuser.gwdg.de/~parallel/scc-course/modules.webm}} ==== Compiling Software ==== {{http://wwwuser.gwdg.de/~parallel/scc-course/compiling-software.webm}} ==== Introduction into Slurm ==== {{url>https://www.youtube.com/embed/JCS9PO-Jp1I 560,315 noscroll noborder}} ==== Resource Selection ==== {{url>https://www.youtube.com/embed/cl3HNS94QR8 560,315 noscroll noborder}} ==== Jobscripts and /scratch Usage ==== {{url>https://www.youtube.com/embed/F-iYYgw-X5g 560,315 noscroll noborder}} ==== Longer Jobs, the fat+ partition, GPUs and Debugging ==== {{url>https://www.youtube.com/embed/yFWlDu28pFA 560,315 noscroll noborder}} ==== Job Arrays, Dependencies and Useful Slurm Parameters ==== {{url>https://www.youtube.com/embed/yFWlDu28pFA 560,315 noscroll noborder}}
