+# Important Things @UNIVIE
+
+The ZID offers a lot of information on its services, most importantly your **u:account**.
+
+Services:
+
+- [u:account](https://zid.univie.ac.at/uaccount/) everything depends on it
+- [vpn](https://zid.univie.ac.at/vpn/) access to only university wide things (our servers)
+- [u:cloud](https://ucloud.univie.ac.at) University cloud
+- [u:access](https://bibliothek.univie.ac.at/en/uaccess.html) library access for publications
+- [gitlab/mattermost](https://gitlab.phaidra.org/imgw) code development / socializing
+- [u:wiki](https://wiki.univie.ac.at/display/theomet) documentation of workflows, group communication, tutorials, intranet, ...
+    * Lots of tutorials for specific problems (travel, expenses, new employees, printer, ...)
+    * HPC / Computing information and guidelines
+    * Please login once. More access can be granted afterwards.
+- [wolke.img.univie.ac.at](https://wolke.img.univie.ac.at)
+    * Landing Page of IT service @ IMGW
+    * User Management [IPA](https://wolke.img.univie.ac.at/ipa/ui)
+---
+
+# Hardware @ IMGW
+
+Documentation: [Computing@u:wiki](https://wiki.univie.ac.at/x/6kW0Bw) or [Computing@gitlab](https://gitlab.phaidra.org/imgw/computer-resources) (public)
+
+Currently the department has:
+- SRVX1 (Teaching and development node) access: open
+    * All Students
+    * All Staff
+    * Teaching
+    * Development Node for interactive computing
+- SRVX8 (Staff, graphical node, VNC, GPU) access: univie
+    * special use cases
+    * used for VNC
+- JET Cluster (2+7, Staff, HPC) access: univie
+    * default access for staff
+    * some master students
+    * slurm scheduler
+- [VSC](https://vsc.ac.at) 4/5 (Staff, HPC), managed by VSC. access: univie
+    * Our department has private Nodes on VSC4 and VSC5
+    * Request an account with IT
+    * slurm scheduler

+![](../img/IMGW-connection-diagram2.png)
+
+---
+
+# Tools - How to connect?
+Depending on your operating system (OS) you should find the right tool to connect. 
+
+Options:
+
+- Web browser - Jupyterhub running Jupyter Notebooks
+    * Teaching Hub on [SRVX1](https://srvx1.img.univie.ac.at/hub)
+    * Research Hub on [JET01](https://wolke.img.univie.ac.at/researchhub)
+- SSH (Windows: Putty, ...)
+- SFTP (Windows: Mobaxterm, winscp, ...)
+- VNC to SRVX8
+    * install a vnc client on your OS
+    * launch a vnc server on SRVX8, run: `userservices vnc -h` 
+    * more information on @gitlab @VNC
+
+---
+
+# Login and Passwords 
+
+When you login the first time, you will need to change your password. **Please be advised that you should choose a secure one.** *A password manager is recommended.*
+
+```bash
+$ ssh [user]@srvx1.img.univie.ac.at
+$ ssh [user]@jet01.img.univie.ac.at
+# from home to jet directly
+$ ssh -J [user]@srvx1.img.univie.ac.at [user]@jet01.img.univie.ac.at
+# or using the ZID server
+$ ssh -J [u:account]@login.univie.ac.at [user]@jet01.img.univie.ac.at
+```
+
+Each of these require a different password:
+
+- IMGW Servers (srvx1, srvx8, jet)
+- u:account
+- eduroam
+- TeachingHub + OTP
+- (optional) iLibrarian
+
+---
+
+# Services @ Servers
+
+All servers try to be up to date and will be updated regularly, the base OS is Red Hat OS 8/AlmaLinux 8. 
+
+All servers handle software like this:
+- environment modules, run: `modules av`
+    * different compilers: gnu, intel
+    * libraries: math, eccodes, netcdf ,...
+    * different MPI
+    * tools: teleport, ecaccess, ...
+- userservices, run: `userservices`
+    * **quota**
+    * server-schedule
+    * weather
+    * containers
+    * yopass
+    * filetransfer
+    * transfersh
+- singularity containers, advanced topic.
+    * building singularity containers for HPC applications
+    
+---
+
+# Services @ Servers 2
+
+Locations on Servers are very important. Where to store and find what?
+
+| name | Server | Path | Quota | comment |
+| --- | --- | --- | --- | --- |
+| HOME | srvx1 | `/users/staff/[user]` | 100 GB | source code, daily backup |
+| HOME | jet01 | `/jetfs/home/[user]` | 100 GB | source code, daily backup |
+| SCRATCH | srvx1 | `/scratch/das/[user]` | 1 TB | data, no backup |
+| SCRATCH | srvx1 | `/scratch/mas/[user]` | 1 TB | data, no backup |
+| SCRATCH | jet01 | `/jetfs/scratch/[user]` | no | data, no backup |
+| DATA | srvx1 | `/data/[dataset]` | no | data, daily backup, constant |
+| SHARED-DATA | srvx1 | `/scratch/shared/[dataset]` | no| data, no backup, shared |
+| SHARED-DATA | jet01 | `/jetfs/shared-data/[dataset]` | no| data, no backup, shared |
+
+All these paths can be remembered by running `userpaths`
+
+
+---
+
+# DATA Management
+
+Science is about computing, but mostly about data and storaging that data.
+
+| name | Server | Path |
+| --- | --- | --- |
+| DATA | srvx1 | `/data/[dataset]` | 
+| SHARED-DATA | srvx1 | `/scratch/shared/[dataset]` |
+| SHARED-DATA | jet01 | `/jetfs/shared-data/[dataset]` |
+
+Please fill in the **Database** and follow the **Data Guidelines**, that can be found in these directories.
+**Add a short decsription of your data and whom to contact for more information.**
