Getting Started

Quick Start

1. Request your server account.
2. Set up your password manager.
3. Connect via SSH.
4. Change your initial password.
5. Explore available resources.

Welcome to the Department of Meteorology and Geophysics

Tasks to complete for newcomers, it is recommended that you print this page an tick off your steps:

• Request a server account via your supervisor
• Receive the inital user account information via mail.
• Setup a password manager. ZID tips, e.g. Bitwarden or KeepassXC
• How to connect using SSH, read the connection 101
  • on Windows install a SSH-Client, e.g. Bitwise, MobaXterm, Putty,...
• Change your initial password with one of these options:
  • browser (https://wolke.img.univie.ac.at/ipa/ui)
  • terminal ssh [username]@login.img.univie.ac.at
• Optional: Create a ssh-key and add it to your profile on the IPA
• Apply for your first VSC Training course, e.g. Introduction to Working on the VSC Clusters

Setting Up Your Environment

When you are new to using servers and linux, these few steps might help to get started. However, it is recommended to make a linux introductionary course, e.g. VSC introduction to linux.

Steps:

• Login to Aurora using SSH: ssh [username]@login.img.univie.ac.at More on Aurora
• There are user specific directories, run: userpaths to understand where different data resides. e.g.
  • HOME, SCRATCH (personal), DATA, SHARED, WEBDATA, ?_JET
• check available environment modules by running: module av and load Anaconda3 module by running: module load Anaconda3. This should allow you to run some python programs.
• list and unload modules: module list and module purge. More on Modules
• run: userservices to get some IMGW special tools. Maybe check the weather!?

Please find a useful summary of commands in the IMGW cheatsheet

Available Computing Resources

The Department of Meteorology and Geophysics has access to the following computing resources:

• Teaching Server (SRVX1)
• Development Server (Aurora)
• Computing Cluster (JET)
• Vienna Scientific Cluster (requires vsc account, VSC)

External resources:

• European Center for Medium-Range Weather Forecast (requires additional account, ECMWF)
• Earth Observation Data Center (requires imgw account, EODC, website)

Please read about access, hardware and quotas at these different resources. A good starting point is here

Troubleshooting

• If you cannot connect via SSH, check your network or VPN settings.
• For password issues, use the IPA web interface or contact IT.
• See FAQ Python for more help on Python.
