Resources for Linux on HPC
Rocky Linux is the Operating System running on the CLAIX system and it is therefore required to have good foundational knowledge about its file structure, command line, scripting, ssh among other aspects of Linux.
To help you learn the required tools need to use the CLAIX HPC system, our partners at HPC.NRW have prepared a series of video Tutorials explaining the most important aspects of Linux.
Please make sure you use the HPC.NRW Tutorials to develop experience using Linux, since the CLAIX HPC system requires it.
To have a quick overview, please attend ur HPC Introduction Workshops or check the Slides from past events.
We will only be able to properly help support requests that meet a minimum Linux Knowledge. For this reason we recommend that you become familiar with these topics!
