Registration/Login/Username

1 Login Username

All members of universities and colleges in Baden-Württemberg can use the bwHPC resources. Prefixes are used to ensure that the usernames assigned by the home organization are unique within the state. The username for the bwHPC clusters is the same as the one assigned by the university or college, but it is prefixed with two letters for the home institution.

Users from the KIT, don't need a prefix on the bwUniCluster.

There are two ways to find out your username for the bwForCluster and the bwUniCluster:

• Get your Username by adding a Prefix to your local Account Name
• Find out your Username by visiting the Registration Service

1.1 Get your Username by adding a Prefix to your local Account Name

If your university is not listed in the bwIDM Membership Table, please ask your university to join bwIDM or update the table.

If you want to use a bwForCluster you need to add a prefix to your local username. But there is one exception:

• If you want to use the bwUniCluster and you are not a member of KIT, you also need to add a prefix.
• BUT: KIT users do not need to use a prefix on the bwUniCluster.

The username is constructed as follows (see Examples below):

<prefix>_<local username>

1.1.1 Prefix for Universities of Applied Sciences

For universities see table below, users from the HAW BW e.V. or a university of applied sciences should use this table updated by bwIDM as a guideline:

• If you are a member of the University of Konstanz and your local username is ab1234, your username on any bwHPC cluster is kn_ab1234.
• If your local username for the university is vwxyz1234 and you are a user of the University of Freiburg, your username on any bwHPC cluster is fr_vwxyz1234.
• If you are from Aalen University and your username is xyzs12342, your username for any bwHPC cluster is aa_xyzs12342.
• KIT users logging into a bwForCluster must use a prefix. If you are a KIT user and your username is pxd27239, your login name for a bwForCluster would be ka_pxd27239.
• If your KIT username is pxd27239,you can use the same username for the bwUniCluster.
