====== Training ======

We provide courses and courses to our users for which you can find the details below. All material (slides, exercises) can be found on the [[habrok:additional_information:course_material:|]] page.

For questions about the courses you can contact us at [[hpc@rug.nl]].

===== Large scale computations and data analysis on the Hábrók cluster ====

Often the power of the desktop PC or laptop is not enough to perform simulations or analyses of huge datasets. The Hábrók cluster with more than 19000 CPU cores can help you in tackling this problem. In this four hour course you will learn how to work with this system.

==== Contents ====

The following topics will be discussed:
  * What the cluster can do for you
  * How to get access to the system
  * How to work with the Linux command-line environment
  * How to transfer data to and from the cluster
  * How to find, and get access to the available software
  * How to start and monitor calculations on the cluster

The course has been split in two parts. The first part addresses logging in to the system and the use of the Linux environment. The second part will discuss the setup of the cluster, the available software and starting real calculations. For people who already have knowledge about the Linux command-line environment it is possible to only attend the second part.

All the materials for this course are available on our wiki [[habrok:additional_information:course_material|here]].

==== Course format ====

The course will be a mixture of lectures and hands-on exercises, in which you will work with the concepts explained.

==== Aim ====

After the course you should understand what a computer cluster is, how to log in to the system, how to work with the command-line environment, be able to transfer data, and submit calculations as jobs to the system.

==== Prerequisites ====

No knowledge about clusters or Linux necessary. All examples are based on (free to download and use) software already available on the university Windows desktops. Pointers to alternative software will be given for Mac and Linux users.

==== Course dates ====

The course is given monthly, except for the summer period. The courses are given in the afternoon from 13:00 to 17:00. The course is given on site and online alternatingly. The following dates are planned for now:

==== 2025 / 2026 ====
  * Tuesday 12 May, online through Kaltura: [[https://forms.gle/sMgVQS9L7B2woz7u9|Registration link]]
  * Thursday 18 June, on site in room 5415.0042 (Landleven 1) [[https://forms.gle/1gJkpKKvggwFGWaD7|Registration link]]

Please be aware that filling in the registration form requires logging in to your RUG account. If you would like to attend the course, but don't have a RUG account, please contact us at [[hpc@rug.nl]], but be aware that for using Hábrók a RUG account is required as well.

===== Research Support Hub =====

We now give workshop sessions within the context of the [[https://www.rug.nl/society-business/center-for-information-technology/research/rsh/|Research Support Hub]] instead of the advanced course. You can find the Research Support Hub calendar [[https://www.rug.nl/society-business/center-for-information-technology/research/rsh/rshcalendar/|here]].

The first of these sessions took place 9th of April and was on **Working with Python on Hábrók**. You can find more information about that session [[https://www.rug.nl/society-business/center-for-information-technology/research/rsh/rshcalendar/260409pythononhabrok|here]] the course material used during the session [[.:courses:rsh_python_habrok|here]].


===== Advanced Hábrók course ====

In the past, we provided an advanced follow-up version of the Hábrók course. Due to low course attendance, this has been discontinued, but you can still find the course material in the relevant [[habrok:additional_information:course_material#:|page]].
