EGU 2026 session about high-performance computation in the geosciences

Computational Geography group — Mon, 20 Oct 2025 10:06:42 GMT

Together with colleagues from five European research institutes we have submitted a session proposal for the EGU 2026 General Assembly in Vienna, Austria. The session is about high-performance computation in the geosciences. We are happy to report that the session has been accepted into the programme as part of the programme group Earth & Space Science Informatics.

You can find more information about this session on the EGU26 home page.

If your work fits within its scope, then we invite you to submit an abstract to this session. Abstract submission will be open from 22 Oct 2025 to 15 Jan 2026, 13:00 CET. We look forward to meeting you in Vienna in May 2026!

First hands-on LUE short course given

Computational Geography group — Wed, 06 Sep 2023 09:29:59 GMT

At June 29 we organized the first hands-on LUE short course. In about three hours the course participants learned everything that is needed to get started with using LUE to build scalable simulation models.

In turn, the following topics where handled:

Introduction of the LUE modelling framework
How to execute LUE models
The hydrological case-study model
Measuring performance and scalability
The factors influencing performance and scalability
Calculating the scalability of the case-study model
Relation LUE vs PCRaster, and upcoming developments

The group of course participants consisted of people working at both research institutes and private companies. Some of them where in the room with us and some where joining online.

We think the course was a success. Everybody learnt a lot, including us.

We will be organizing more LUE courses over time. If you are interested in joining us, then do let us know (lue@computationalgeography.org), and we will notify you once we picked a date.

Hands-on LUE short course

Building scalable spatial simulation models the easy way

We are organizing a short introductory course about using LUE to develop scalable numerical spatial simulation models. At June 29, between 14:00-17:00 we will explain everything you need to get started with using LUE yourself. We will cover at least the following topics:

An overview of how LUE works internally, without the details.
Installing LUE. Bring your own device!
Develop a simple model using the LUE Python binding. Verify that all the CPU cores are being used.
Q&A. Ask us anything.
Drinks.

The course will be held at our institute at the Utrecht Science Park, the Netherlands, but it will be possible for people to join online as well. Participation is free of charge.

In case you are interested in participating in this course, then please let us know (lue@computationalgeography.org), with answers to the following questions:

Do you prefer to join us on-site or online?
Any suggestions for the course? For example: topics we should not forget to cover, or a case you are particularly interested in.

We would be grateful if you could extend this invitation to any of your colleagues who might be interested in learning about LUE.

AMT/HPX workshop EGU 2023

Computational Geography group — Mon, 07 Nov 2022 13:29:22 GMT

The Computational Geography group is organizing a workshop about parallel programming using asynchronous many-tasks (AMT) and the HPX C++ library during the EGU General Assembly 2023 in Vienna. AMT/HPX is used in the implementation of the LUE framework. During this workshop we will introduce this approach and illustrate how it is used in LUE.

This workshop is especially relevant for C++ software developers interested in developing scalable software. Knowing about AMT/HPX is not required for LUE users, but it might be interesting for them too.

For more information, see the associated short course page on the EGU23 website.

LUE workshops december 2022

Computational Geography group — Mon, 07 Nov 2022 13:26:18 GMT

We are planning one or several online workshops, specifically about the support for large scale field-based modelling that is part of LUE. These will be informal sessions of one hour in which we will shortly introduce LUE and discuss opportunities for cooperation with the attendants.

In the next few weeks we will add information about these workshop and how to subscribe to them to this page. See the LUE homepage for possibilities to keep up to date about the LUE project, including these workshops.
