Get an account on the system

UiB and IMR

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. UiB users will have the same password as they have on other UiB systems.

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

NOTUR

Hexagon is not part of the NOTUR project anymore. If you need an account on one of the NOTUR systems, you can apply at this link.

Connect to the system

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

Starting from 14th of June, access to Hexagon is restricted to UiB and IMR campus networks. Users traveling or working outside of these networks will have to use VPN.

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

Obtain a new password

If you are an UiB user, your password is the same as for the other UiB systems, you can change it at https://sebra.uib.no. Otherwise please contact Support.

Change password

UiB users can change their passwords at Sebra.
Non-UiB users will have to contact Hexagon Support.

Hexagon login nodes have a read-only file system, therefore it is not possible for the user to change his password directly.

The next steps for hexagon users

You can find a short introduction to UNIX CLI in Introduction to Unix CLI. This section contains a list of some useful bash commands, short presentation of UNIX file system, processes, environment, etc.

You can find information about how to write job scripts and submit jobs in Job execution (Hexagon). In the same place you will also find details about queue system setup, job limitations, default resources and policies.

Information about operations on data, like file transfers, archiving, and proper use of file systems is located in Data (Hexagon).

The Application development (Hexagon) page contains descriptions of the available tools to build your code, like compilers and debuggers, as well as the specific details for the compilation for a Cray XE system.

In General_software_and_libraries_(Hexagon) you will find information about supported and unsupported popular scientific applications, as well as information about various optimized scientific libraries.

Resources contains links to external resources with valuable information about how to use and utilize Cray XE system.
