-## Onboarding
-
-The supercomputer used for the exercises is [JUWELS Booster](https://apps.fz-juelich.de/jsc/hps/juwels/booster-overview.html), a system located at Jülich Supercomputing Centre (Germany) with about 3700 NVIDIA A100 GPUs.
-
-Visual onboarding instructions can be found in the subfolder of the according lecture, `01b-H-Onboarding/`. Here follows the textual description:
-
-* Register for an account at [JuDoor](https://judoor.fz-juelich.de/login)
-* Sign-up for the [`training2232` project](https://judoor.fz-juelich.de/projects/join/training2232)
-* Accept the Usage Agreement of JUWELS
-* Wait for wheels to turn as your information is pushed through the systems (about 15 minutes)
-* Access JUWELS Booster via [JSC's Jupyter portal](https://jupyter-jsc.fz-juelich.de/)
-* Create a Jupyter instance using `LoginNodeBooster` and the `training2232` allocation on JUWELS *(see slides for screenshots)*
-* When started, launch a browser-based Shell in Jupyter
-* Source the course environment to introduce commands and helper script to environment
-  ```
-  source $PROJECT_training2232/env.sh
-  ```
-* Sync course material to your home directory with `jsc-material-sync`.
-* *Recommended*: Install [Nsight Systems profiler](https://developer.nvidia.com/gameworksdownload#?dn=nsight-systems-2022-4) for third session (also available via [package managers](https://developer.download.nvidia.com/devtools/repos))
-* **Slido**: [SC22_sess196](https://app.sli.do/event/gJM6zs4JMsoYT4fcJ3oWeP)
-
-You can also access JSC's facilities via SSH. In that case you need to add your SSH key through JuDoor. You need to restrict access from certain IPs/IP ranges via the `from` clause, as explained [in the documentation](https://apps.fz-juelich.de/jsc/hps/juwels/access.html#ssh-login). We recommend using Jupyter JSC for its simplicity, especially during such a short day that is the tutorial day.
