The Hábrók system is available to support scientific research and education. University staff members that want to use the system for these purposes can request an account. Students may also use the system for these purposes (e.g. courses, theses, or projects), but only with approval from their course/thesis/project supervisor.
You can request an account through the Self-Service Portal Iris. Please go to Research and Innovation Support → Computing and Research Support Facilities → Computing (Hábrók, Merlin) → Request Hábrók account. You can then fill in the form and submit it. Please note that you need to login to the Self-Service Portal with your RuG credentials.
You will be automatically subscribed to the Hábrók user mailing list. We only use this list for important notifications that affect all cluster uses. Unsubscribing from the Hábrók user mailing list can only be done by requesting removal of your Hábrók account (see below).
Users of the cluster have to adhere to the Acceptable use policy of the University of Groningen for university computer systems.
The login node of the cluster is used by all users of the cluster to login and submit jobs. A high load on the login node will impair the usability of the cluster for other users.
It is therefore not allowed to run processes that take a significant amount of memory or CPU power. We have a short queue available if you quickly want to test something. Alternatively, you could use one of the interactive nodes which have less severe restrictions.
Please be aware that the cluster is used by many researchers. We may therefore contact you if you do things that adversely affect the performance of the cluster for other users, in order to try to help you find ways to improve your workflow.
When accounts on the cluster expire, data of the account will be removed, in accordance to the university guidelines for account expiration.
If you want to remove your account from Hábrók, please fill in this form. Make sure you’re logged in with your RUG account to be able to fill in the form. You will then receive a confirmation email to which you need to reply before your account will be removed. Together with losing access to Hábrók, your data will be removed after a week. In addition, you will be unsubscribed from the Hábrók mailing list, and the Flying Falcon mailing list.
