If you want to use the HPC cluster, you need to have an university account (e.g. abcd1234) and the account needs to be part of a cluster group. Cluster groups are basically the work groups which are using the cluster. (You can find a list and other informations about that here: Unix groups) Until now we were using a form on the home page of the scientific computing were you could request an HPC account. This process is now automated and you are able to join a group on your own. To do so, follow these simple steps:

• visit the ServiceDesk
• click on "Self Service Portal verwenden" ("Use the Self Service Portal")
• after a succesfull login, click on "IT-Services" > "Wissenschaftliches Rechnen" ("Scientific Computing"). There you will find a button named "Zugang zum Cluster beantragen" ("Request Access to the Cluster")
• after clicking on the button, you will be directly forwarded to the clustergroup selection
• on the bottom, you can choose the cluster group you want to join
• choose one and submit your choice by clicking on "Übernehmen" ("Submit"). If your desired group isnt listed, please contact the .

An administrator will then check, and most likely confirm your request. After that you will be able to use your university account for logging into the cluster.

Note: If you accidentally joined the wrong group or if you simply want to switch to a other group, you follow the steps described above too.
