Get an account on the system

UiB, IMR and Uni Research AS

To get a user account on one of the supercomputers at UiB you need to complete the account application form. This is valid also for users that already have accounts on other UiB machines.

You will be notified by email as soon as the account is established. If you provided your mobile phone number in the application form you will receive the password via SMS.

The regulations of use for computer equipment at the University of Bergen can be found here.


NOTUR

To get an account on hexagon via the NOTUR project please follow this link.

Connect to the system

You will be able to connect to the supercomputers at UiB only via SSH.

Please refer to the Secure Shell page for basic information regarding ssh and related utilities.

Obtain a new password

If you are a NOTUR user you can obtain a new password at Metacenter page, otherwise please contact Support.

Change password

NOTUR users can change their passwords at Metacenter page.

Hexagon login nodes have a read-only file system, therefore it is not possible for the user to change his password directly. If you want to change the password on Hexagon please contact Support.

Users of the fimm cluster can change the password on Fimm and then request that their new password is to be transferred to Hexagon via Support.
